Matthias Heidbrink: /* Metrahit 1x series */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==

* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''14S'', ''ONE Plus'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232-II ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer and data storage.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Multimeters */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

The '''[[Gossen Metrawatt]] Metrahit 25S''' is a 4.5 digit, 31000 counts 1000V CAT III/600 V CAT IV handheld digital multimeter with IR (RS232) connectivity.

== Hardware ==

* '''Power supply''':
** Battery: 2x ''1,5 V IEC R 6'', ''IEC LR 6'' or corresponding NiCd rechargeable batteries
* '''Fuse''':
** Current 300 mA: FF (UR) 1,6 A/1000 V AC/DC (10 kA) 6,3 mm x 32 mm
** Current 3A/10A: FF (UR) 10 A/1000 V AC/DC (30 kA) 10 mm x 38 mm

== Photos ==



== Using the device with sigrok ==
The device is supported in ''Send Mode'' using a [[Gossen_Metrawatt#Metrahit_RS232 | RS232 interface]] by the driver gmc-mh-1x-2x-rs232 (actually this should work, but with [[User:Matthias Heidbrink | Matthias']] test device it did not, so it's untested). Set the multimeter to use the communication adaptor ''RS232''.

The multimeter is also supported in bidirectional mode using a [[Gossen_Metrawatt#Metrahit_BD232 | BD232]] or [[Gossen_Metrawatt#Metrahit_SI232-II | SI232-II]] interface by the driver gmc-mh-2x-bd232. Set the multimeter to use the communication adaptor ''BD232''.

The device might be not detected by the driver if it is in a mode where it sends data rarely, either with a huge send interval or with a measurement function that delivers a very low data rate, e.g. temperature measurements with K type sensor. Then it should be set to a mode with higher data rate during the initialisation of the driver.

The '''[[Gossen Metrawatt]] T-Com KMM2002''' is a 3100 counts handheld digital multimeter with IR (RS232) connectivity and insulation measurement (100 V). It seems to be an OEM version of the ''Metrahit 16T'' especially made for T-Com (Deutsche Telekom). Additional features seems to be a backlight and a 30 nF capacity range.

The resolution is one digit higher on the data interface.

== Hardware ==
* '''Battery''': ''9 V IEC 6 LR 61''
* '''Fuse''': None! (not required, no internal amps ranges)

* TODO.

The '''Siemens B1105''' is a 310000 counts 1000V CAT III/600 V CAT IV (older version) or 600V CAT III/300 V CAT IV (newer version) handheld digital multimeter with IR (RS232/USB) connectivity.

It is an OEM version of the [[Gossen Metrawatt]] [[Gossen Metrawatt Metrahit 28S | Metrahit 28S]]. The only differences seem to be the type, logo and color (light grey-blue print on knob, light grey-blue holster) and the voltage rating.

== Hardware ==

* '''Power supply''':
** Battery: 2x ''1,5 V IEC R 6'', ''IEC LR 6'' or corresponding NiCd rechargeable batteries
** External power supply ''NA4/500'' by Gossen Metrawatt, 4.2 V, 500 mA (for older version)
** External power supply ''NA5/600'' by Gossen Metrawatt, 5 V, 600 mA (for newer version, 3-pin plug)
* '''Fuse''':
** Current 300 mA: FF (UR) 1,6 A/1000 V AC/DC (10 kA) 6,3 mm x 32 mm
** Current 3A/10A: FF (UR) 10 A/1000 V AC/DC (30 kA) 10 mm x 38 mm

The '''[[Gossen Metrawatt]] Metrahit 29S''' is a 310000 counts 1000V CAT III/600 V CAT IV (older version) or 600V CAT III/300 V CAT IV (newer version) handheld digital multimeter with IR (RS232/USB) connectivity.

It is very similiar to the [[Gossen Metrawatt Metrahit 28S | Metrahit 28S]], but has additional energy measurement and data logging capabilities. While the device is detected and functions common with the Metrahit 28S are expected to work, some of the additional measurement functions are not implemented yet.

Currently energy measurement is supported by driver ''gmc-mh-1x-2x-rs232'' only.

== Hardware ==

* '''Power supply''':
** Battery: 2x ''1,5 V IEC R 6'', ''IEC LR 6'' or corresponding NiCd rechargeable batteries
** External power supply ''NA4/500'' by Gossen Metrawatt, 4.2 V, 500 mA (for older version)
** External power supply ''NA5/600'' by Gossen Metrawatt, 5 V, 600 mA (for newer version, 3-pin plug)
* '''Fuse''':
** Current 300 mA: FF (UR) 1,6 A/1000 V AC/DC (10 kA) 6,3 mm x 32 mm
** Current 3A/10A: FF (UR) 10 A/1000 V AC/DC (30 kA) 10 mm x 38 mm A 16A fuse described in older versions of the manual is '''wrong''' [https://www.gossenmetrawatt.com/resources/zz_tam/hit28-29s/bbl_dgbfeinl_new_fuse.pdf]!

Matthias Heidbrink: /* Multimeters */ Added Gossen Metrawatt Metrahit 28C and 28S.

sigrok is intended as a flexible, cross-platform, and '''hardware-independent''' software suite, i.e., it supports various devices from many different vendors.

Here is a list of currently supported devices (various stages of completeness) and devices we plan to support in the near future.

The lists are sorted by category ([[File:Nuvola OK.png|16px]] supported: [[:Category:Supported|{{PAGESINCATEGORY:Supported|pages}}]], [[File:Nuvola Orange.png|16px]] in progress: [[:Category:In progress|{{PAGESINCATEGORY:In progress|pages}}]], [[File:Nuvola Red.png|16px]] planned: [[:Category:Planned|{{PAGESINCATEGORY:Planned|pages}}]]), and alphabetically within those categories.

Supported hardware

2016-03-26T17:04:30Z

Matthias Heidbrink: /* Multimeters */ Added Gossen Metrawatt Metrahit X-Tra (planned)

sigrok is intended as a flexible, cross-platform, and '''hardware-independent''' software suite, i.e., it supports various devices from many different vendors.

Here is a list of currently supported devices (various stages of completeness) and devices we plan to support in the near future.

The lists are sorted by category ([[File:Nuvola OK.png|16px]] supported: [[:Category:Supported|{{PAGESINCATEGORY:Supported|pages}}]], [[File:Nuvola Orange.png|16px]] in progress: [[:Category:In progress|{{PAGESINCATEGORY:In progress|pages}}]], [[File:Nuvola Red.png|16px]] planned: [[:Category:Planned|{{PAGESINCATEGORY:Planned|pages}}]]), and alphabetically within those categories.

Matthias Heidbrink: /* Metrahit Starline Series */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232-II ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer and data storage.

Works with Metrahit 1x and Metrahit 2x devices.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192/9600 Baud, 950 nm, 8N1. 
RS232: 9600/19200/38400 Baud, 8N1.

4-8 ''SI232-II'' (depending on multimeter types and baud rate) can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232-II'' can be cascaded to measure offline synchronously.

Not available any more.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Communication Hardware */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

The IR signal is just serial data encoded as SIR (''Asynchronous Serial Infrared''; signal inverted, bits only about 3/16 of the ordinary length). While SIR is the physical layer of IrDA for lower baud rates, an IrDA communication adaptor will not work because it implements further protocols on top. Some details (optical specification; 8192 baud and 6 bit modes required by some multimeters) seem not to conform to the SIR specs.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192/9600 Baud, 950 nm, 8N1. 
RS232: 9600/19200/38400 Baud, 8N1.

4-8 ''SI232-II'' (depending on multimeter types and baud rate) can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232-II'' can be cascaded to measure offline synchronously.

Not available any more.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

A USB to SIR converter like [http://lemmini.de/IrDA%20USB/IrDA%20USB.html this nice Open Souce hardware design by 0xdeadbeef/V. Ott] will work as a cheaper replacement.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

Please note that the IR signal is just serial data encoded in a SIR-like fashion (signal inverted, bits only about 3/16 of the ordinary length), not IrDA. The optical specification and the 8192 baud mode required by some multimeters and modes seem not to conform to the SIR specs. No efforts have been done so far to test if the minimum pulse duration specified by SIR is sufficient.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with a type Mini-B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

== Company ==
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

== Multimeters ==
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

=== Metrahit 1x series ===

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

=== Metrahit Starline Series ===
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

== Communication Hardware ==
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

Please note that the IR signal is just serial data encoded in a SIR-like fashion (signal inverted, bits only about 3/16 of the ordinary length), not IrDA. The optical specification and the 8192 baud mode required by some multimeters and modes seem not to conform to the SIR specs. No efforts have been done so far to test if the minimum pulse duration specified by SIR is sufficient.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

=== Metrahit 1x/2x series ===
==== Metrahit RS232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

==== Metrahit SI232 ====
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

==== Metrahit BD232 ====
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

==== USB-Hit ====
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

=== Metrahit Starline Series ===
==== USB X-Tra ====
IR↔USB adaptor for the ''Starline Series'' devices.

==== Bluetooth ====
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

=== Metraport Series ===
==== USB ====
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Communication Protocols ==
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

=== Metrahit 1x/2x Send Mode ===
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

=== Metrahit 2x Bidirectional Mode ===
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

=== Metrahit 30M ===
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

=== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ===
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

=== LabView ===
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink:

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

Please note that the IR signal is just serial data encoded in a SIR-like fashion (signal inverted, bits only about 3/16 of the ordinary length), not IrDA. The optical specification and the 8192 baud mode required by some multimeters and modes seem not to conform to the SIR specs. No efforts have been done so far to test if the minimum pulse duration specified by SIR is sufficient.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

The adaptor contains just discrete components and ICs, no microcontroller.

=== Metrahit SI232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

== Metraport Series ==
=== USB ===
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Metrahit Starline Series */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Company =

* https://de.wikipedia.org/wiki/Gossen_Metrawatt

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

Please note that the IR signal is just serial data encoded in a SIR-like fashion (signal inverted, bits only about 3/16 of the ordinary length), not IrDA. The optical specification and the 8192 baud mode required by some multimeters and modes seem not to conform to the SIR specs. No efforts have been done so far to test if the minimum pulse duration specified by SIR is sufficient.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

The adaptor contains just discrete components and ICs, no microcontroller.

=== Metrahit SI232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

== Metraport Series ==
=== USB ===
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes. One model, the ''Metrahit Outdoor'', even has IP65 protection! The disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB.

Please note that the IR signal is just serial data encoded in a SIR-like fashion (signal inverted, bits only about 3/16 of the ordinary length), not IrDA. The optical specification and the 8192 baud mode required by some multimeters and modes seem not to conform to the SIR specs. No efforts have been done so far to test if the minimum pulse duration specified by SIR is sufficient.

The ''Metrahit Ultra BT'' also supports Bluetooth. The ''Metraport 40S'' communicates via integrated USB only.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

=== USB ===
The ''Metraport 40S'' has got an integrated USB 1.1 interface with USB Mini-B receptacle.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Metrahit BD232 */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes (one model, the ''Metrahit Outdoor'', even has IP65 protection!), the disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB. Please note that the IR signal is just serial data encoded in a SIR-like fashion, not IrDA or SIR.

The ''Metrahit Ultra BT'' also supports Bluetooth.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

=== Metrahit SI232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 1x and 2x devices and the 30M.

With Metrahit 2x/30M devices up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Metrahit 1x/2x Send Mode */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Company =
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes (one model, the ''Metrahit Outdoor'', even has IP65 protection!), the disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB. Please note that the IR signal is just serial data encoded in a SIR-like fashion, not IrDA or SIR.

The ''Metrahit Ultra BT'' also supports Bluetooth.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

=== Metrahit SI232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 2x devices, including 30M.

Up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

[[User:Matthias Heidbrink|Matthias']] experience is that this adaptor works as a replacement for a ''Metrahit RS232'' with Metrahit 1x devices on ''some'' RS232 ports, but not on others. This is unsupported by the manufacturer.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 18C/27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

Matthias Heidbrink: /* Metrahit 1x series */

Gossen Metrawatt is a German manufacturer of professional and high-end test and measurement equipment, including multimeters.

This article tries to give an overview of the multimeters with interfaces for data exchange, OEM models and communication.

= Company =
* http://www.gossenmetrawatt.com/ (Homepage)
* https://de.wikipedia.org/wiki/Gossen_Metrawatt

= Multimeters =
One remark concerning device names: The manufacturer writes the name of the device series sometimes "METRAHit", sometimes ''METRAHIT'' or even ''METRA HIT'', sometimes not even consistently for the same device. For simplicity it will be "Metrahit" here most of the time, other names alike.

These multimeter can send data unidirectionally via IR/RS232 (''Send Mode''). It seems that the 3100 count types are actually 31000 count types that do not display the last digit, but can deliver it via the serial interface.

Currently the ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'' and ''18S'' are supported by ''sigrok'' using the driver ''gmc-mh-1x-2x-rs232''.

The models marked with ○ in the ''Supported'' row are untested, but expected to work. See section [[#Metrahit_1x.2F2x_Send_Mode | Metrahit 1x/2x Send Mode]] for details.

Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of the unsupported devices and can test it.

The devices are not available from Gossen Metrawatt any more, but it seems that a company in India named [http://rishabh.co.in/ Rishabh] makes slightly redesigned versions of some models. The [[HT Instruments HT410]] seems to be another OEM model, probably made by Rishabh.

The Metrahit 1x series includes some more devices (''Metrahit 15'' and ''16'' without letter, Milliohm Meter ''Metrahit 17'', some sold as ancestor brand ''ABB Metrawatt'') that are unsupported because they do not have an IR interface.

The Metrahit 2x series supports unidirectional (''Send Mode'') and bidirectional data exchange via IR.

Currently the ''Metrahit 25S'' and ''28S (Siemens B1105)'' are supported by two different drivers:
* gmc-mh-1x-2x-rs232: ''Send Mode''
* gmc-mh-2x-bd232: ''Bidirectional Mode''

The models marked with ○ in a Supported row are untested, but expected to work. Please contact [[User:Matthias_Heidbrink|Matthias]] if you have one of these unsupported devices and can test it.

See [[#Communication_Protocols | Communication Protocols]] for more details.

== Metrahit Starline Series ==
The series of newer devices with only three sockets (only one socket for all current measurement ranges) is called ''Starline Series''. The manufacturer sub-divides this further into an ''A Series'', ''E Series'' and ''S Series'', which does not make a big difference concerning communicating with the devices.

= Communication Hardware =
Most Gossen Metrawatt multimeters having data communication support communicate unidirectionally or bi-directionally through the case using IR and proprietary communication adaptors. The advantage of this construction is that it allows a closed case without unnecessary holes (one model, the ''Metrahit Outdoor'', even has IP65 protection!), the disadvantage is a need for special, expensive adaptors to convert this to common RS232 or USB. Please note that the IR signal is just serial data encoded in a SIR-like fashion, not IrDA or SIR.

The ''Metrahit Ultra BT'' also supports Bluetooth.

== Metrahit 1x/2x series ==
=== Metrahit RS232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

RS232 parameters: 8192 (Metrahit 1x)/9600 Baud (Metrahit 2x), 6N1, DTR ON, RTS ON.

The communication speed of 8192 Baud and 6 data bits might not be supported by some operating systems and many [[Serial port#USB to serial converters|RS232-USB adaptors]].

Not available any more.

</gallery>

The adaptor contains just discrete components and ICs, no microcontroller.

=== Metrahit SI232 ===
IR→RS232 adaptor for unidirectional communication from the multimeter to the computer and data storage.

Works with Metrahit 1x and with Metrahit 2x devices in ''Send Mode''.

Up to six ''SI232'' can be cascaded to communicate to the computer via a single RS232 interface. Up to 10 ''SI232'' can be cascaded to measure offline synchronously.

128 kByte battery-buffered CMOS memory, up to about 100000 data sets.

Multimeter: 8192 Baud, 950 nm, 6N1. 
RS232: 9600/19200/38400 Baud, 8N1.

Not available from Gossen Metrawatt any more. It seems that Rishab in India [http://rishabh.co.in/ 1] still sells it as OEM product ''Rish SI232''.

=== Metrahit BD232 ===
IR↔RS232 adaptor allowing bidirectional communication between multimeter and computer.

Works with Metrahit 2x devices, including 30M.

Up to six ''BD232'' can be cascaded to communicate to the computer via a single RS232 interface. When only Metrahit 2x multimeters are used, ''BD232'' and ''SI232'' adaptors can be mixed.

9600 Baud.

[[User:Matthias Heidbrink|Matthias']] experience is that this adaptor works as a replacement for a ''Metrahit RS232'' with Metrahit 1x devices on ''some'' RS232 ports, but not on others. This is unsupported by the manufacturer.

=== USB-Hit ===
IR↔USB adaptor for Metrahit.

For Metrahit 2x/30M devices only.

== Metrahit Starline Series ==
=== USB X-Tra ===
IR↔USB adaptor for the ''Starline Series'' devices.

== Bluetooth ==
Bluetooth 2.1 + EDR, Class 2

For the ''Metrahit Ultra BT''.

= Communication Protocols =
While the older devices MetraHit 1x-30M use proprietary protocols, the newer devices of the socalled ''Starline Series'' use a protocol close to SCPI. Descriptions of the communication protocols are available from the manufacturer.

== Metrahit 1x/2x Send Mode ==
Proprietary binary protocol. Used for sending data from multimeter to PC.

This mode is supported by the driver ''gmc-mh-1x-2x-rs232'' using the interface [[#Metrahit_RS232|RS232]]. 

Supported devices: ''Metrahit 14A'', ''15S (HT410)'', ''16I'', ''KMM2002'', ''18S'', ''25S'', ''28S'' (Siemens B1105), ''29S''.

Other devices of the Metrahit 1x/2x series except the 27x/28Cx devices should work, too, but are untested.

== Metrahit 2x Bidirectional Mode ==
Proprietary binary protocols. Used for bidirectional communication between computer and most Metrahit 2x multimeters.

There seem to be several "sub-modes". See description available from manufacturer on request.

This mode is supported (incompletely) by the driver ''gmc-mh-2x-bd232'' using one of the interfaces [[#Metrahit_BD232|BD232]] or [[#Metrahit_SI232-II|SI232-II]]. The interface [[#USB-Hit|USB-Hit]] might work, too, but is untested.

The driver will try to power on BD232 and SI232-II interfaces and connected multimeters before scanning for devices.
The driver can power off a multimeter using the command SR_CONF_POWER_OFF with a boolean parameter of TRUE.

Supported devices: Metrahit 25S and ''Siemens B1105'' (Metrahit 28S). Other multimeters of the series should work, too, but are untested.

Currently the following restrictions apply:
* Only one multimeter per RS-232 interface supported. Several multimeters on cascaded ''BD232'' or ''SI232-II'' interfaces might be detected, but only one at a time can be used.
* Measured values are read one by one by polling. Depending on the sample rate, this could theoretically cause loss of some values.
* Reading of data stored in memory of storage adaptor SI232-II or multimeter (Metrahit 22M, 26M, 29S) not implemented yet.
* Setting of multimeter configuration not supported yet.

== Metrahit 30M ==
The protocol is proprietary and seems to be quite different from the Metrahit 1x/2x series although communication can use some of the same IR↔Serial adaptors (at least [[Gossen Metrawatt#Metrahit_BD232|BD232]], [[Gossen Metrawatt#USB_Hit|USB-Hit]]).

== Metrahit 27I, 27M, 28C, Starline Series, Metraport 40S ==
Newer Metrahit devices use a proprietary communication protocol that is (mostly) ASCII and oriented at SCPI. A driver is under development.

Depending on the device type, an interface ''[[#Metrahit_BD232|BD232]]'' or ''[[#USB-Hit|USB-Hit]]'' for ''Metrahit 27x'' or ''28C'', ''[[#USB X-Tra|USB X-Tra]]'' for supported devices of the ''Starline Series'' or an USB cable with type B plug for the ''Metraport 40S'' is required.

== LabView ==
Gossen Metrawatt offers LabView drivers for the ''Metrahit Energy'', the ''Metrahit Ultra'' and the ''Metraport 40S''.

** Battery: 2x ''1,5 V IEC R 6'', ''IEC LR 6'' or corresponding NiCd rechargeable batteries
** External power supply ''NA4/500'' by Gossen Metrawatt, 4.2 V, 500 mA (for older version)
** External power supply ''NA5/600'' by Gossen Metrawatt, 5 V, 600 mA (for newer version, 3-pin plug)
* '''Fuse''':
** Current 300 mA: FF (UR) 1,6 A/1000 V AC/DC (10 kA) 6,3 mm x 32 mm
