<br />
The RDTech TC66C (~$25 USD) is a USB-C load meter which can measure various properties of USB-C devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. This device is similar to the [[RDTech UM series]] of devices, but doesn't use the same protocol.<br />

<br />
=== Checksum algorithm ===<br />
Checksums are implemented using CRC-16/MODBUS zero-extended to fit a 32-bit field.<br />
<br />
=== Encryption algorithm ===<br />
Poll packets are encrypted using AES in ECB mode using the following static key:<br />
<pre><br />
0x58, 0x21, 0xfa, 0x56, 0x01, 0xb2, 0xf0, 0x26,<br />
0x87, 0xff, 0x12, 0x04, 0x62, 0x2a, 0x4f, 0xb0,<br />
0x86, 0xf4, 0x02, 0x60, 0x81, 0x6f, 0x9a, 0x0b,<br />
0xa7, 0xf1, 0x06, 0x61, 0x9a, 0xb8, 0x72, 0x88,<br />
</pre><br />
<br />
Kudos to [https://ralimtek.com/reverse%20engineering/software/tc66c-reverse-engineering Ben V. Brown] for documenting the encryption algorithm and key.<br />
<br />
== Recording format (gtrec) ==<br />
<br />
Recordings dumped using the <code>gtrec</code> command are returned as a list of 32-bit unsigned integer pairs terminated by <code>reck</code>. The first value in the pair is the voltage (multiply by 1e-4 to get voltage) and the second value is the current (multiply by 1e-5 to get Ampere).<br />
<br />
== Firmware update ==<br />
<br />
Firmware update process:<br />
* Issue a <code>query</code> command to verify that the boot loader is active.<br />
* Issue the <code>update</code> command, wait for <code>uprdy</code>.<br />
* Write firmware in blocks of 64 bytes (the last block may be shorter than 64 bytes). Each block is acknowledged with an <code>OK</code> response.<br />
* Device reboots automatically.<br />
<br />
Useful URLs:<br />
* Firmware metadata: [http://www.ruidengkeji.com/rdupdate/firmware/TC66/TC66.json http://www.ruidengkeji.com/rdupdate/firmware/TC66/TC66.json]<br />

=== Checksum algorithm ===<br />
Checksums are implemented using CRC-16/MODBUS zero-extended to fit a 32-bit field.<br />
<br />
=== Encryption algorithm ===<br />
Poll packets are encrypted using AES in ECB mode using the following static key:<br />
<pre><br />
0x58, 0x21, 0xfa, 0x56, 0x01, 0xb2, 0xf0, 0x26,<br />
0x87, 0xff, 0x12, 0x04, 0x62, 0x2a, 0x4f, 0xb0,<br />
0x86, 0xf4, 0x02, 0x60, 0x81, 0x6f, 0x9a, 0x0b,<br />
0xa7, 0xf1, 0x06, 0x61, 0x9a, 0xb8, 0x72, 0x88,<br />
</pre><br />
<br />
Kudos to [https://ralimtek.com/reverse%20engineering/software/tc66c-reverse-engineering Ben V. Brown] for documenting the encryption algorithm and key.<br />
<br />
== Recording format (gtrec) ==<br />
<br />
Recordings dumped using the <code>gtrec</code> command are returned as a list of 32-bit unsigned integer pairs terminated by <code>reck</code>. The first value in the pair is the voltage (multiply by 1e-4 to get voltage) and the second value is the current (multiply by 1e-5 to get Ampere).<br />
<br />
== Firmware update ==<br />
<br />
Firmware update process:<br />
* Issue a <code>query</code> command to verify that the boot loader is active.<br />
* Issue the <code>update</code> command, wait for <code>uprdy</code>.<br />
* Write firmware in blocks of 64 bytes (the last block may be shorter than 64 bytes). Each block is acknowledged with an <code>OK</code> response.<br />
* Device reboots automatically.<br />
<br />
Useful URLs:<br />
* Firmware metadata: [http://www.ruidengkeji.com/rdupdate/firmware/TC66/TC66.json http://www.ruidengkeji.com/rdupdate/firmware/TC66/TC66.json]<br />

=== Checksum algorithm ===<br />
Checksums are implemented using CRC-16/MODBUS zero-extended to fit a 32-bit field.<br />
<br />
=== Encryption algorithm ===<br />
Poll packets are encrypted using AES in ECB mode using the following static key:<br />
<pre><br />
0x58, 0x21, 0xfa, 0x56, 0x01, 0xb2, 0xf0, 0x26,<br />
0x87, 0xff, 0x12, 0x04, 0x62, 0x2a, 0x4f, 0xb0,<br />

0xa7, 0xf1, 0x06, 0x61, 0x9a, 0xb8, 0x72, 0x88,<br />
</pre><br />
<br />
Kudos to [https://ralimtek.com/reverse%20engineering/software/tc66c-reverse-engineering Ben V. Brown] for documenting the encryption algorithm and key.<br />
<br />
== Recording format (gtrec) ==<br />
<br />
Recordings dumped using the <code>gtrec</code> command are returned as a list of 32-bit unsigned integer pairs terminated by <code>reck</code>. The first value in the pair is the voltage (multiply by 1e-4 to get voltage) and the second value is the current (multiply by 1e-5 to get Ampere).<br />
<br />
== Firmware update ==<br />
<br />
Firmware update process:<br />
* Issue a <code>query</code> command to verify that the boot loader is active.<br />
* Issue the <code>update</code> command, wait for <code>uprdy</code>.<br />
* Write firmware in blocks of 64 bytes (the last block may be shorter than 64 bytes). Each block is acknowledged with an <code>OK</code> response.<br />
* Device reboots automatically.<br />
<br />

The RDTech TC66C (~$25 USD) is a USB-C load meter which can measure various properties of USB-C devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. This device is similar to the [[RDTech UM series]] of devices, but doesn't use the same protocol.<br />

}}<br />
<br />
== What is it? ==<br />
<br />
The RDTech <span style="color:green">UM24C</span> (~$12 USD), <span style="color:blue">UM25C</span> (~$16 USD) and <span style="color:darkorange">UM34C</span> (~$18 USD) are USB load meters which can measure various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. They can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). They also allow graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
The <span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> are extremely similar, but have several differences:<br />
<br />
* <span style="color:green">UM24C</span> supports USB-A male / USB-microB female line, USB-A female load.<br />
* <span style="color:blue">UM25C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female / USB-C female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB 3.0 data passthrough; <span style="color:green">UM24C</span>/<span style="color:blue">UM25C</span> are USB 2.0 only.<br />
* <span style="color:blue">UM25C</span> displays and sends 1mV / 0.1mA live resolution, <span style="color:green">UM24C</span>/<span style="color:darkorange">UM34C</span> are 10mV / 1mA live resolution. Note that this is applicable for instantaneous view only; aggregates are the same for all three models.<br />
* <span style="color:green">UM24C</span> is maximum 3A current, <span style="color:darkorange">UM34C</span> is 4A, <span style="color:blue">UM25C</span> is 5A.<br />
* <span style="color:green">UM24C</span> only supports detection of unknown (normal) charging mode, QC2.0 and QC3.0, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> support detecting additional charging modes. This does not affect the line/load from negotiating a charging mode, just the meter's ability to detect it.<br />
* <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a switch which lets you turn on and off the Bluetooth functionality.<br />
* <span style="color:green">UM24C</span> is not supported by their Apple app, only <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>.<br />
<br />
The <span style="color:blue">UM25C</span> is the most fully featured of the three, but is missing USB 3.0 data passthrough (<span style="color:darkorange">UM34C</span> only). If you have to buy one, get the <span style="color:blue">UM25C</span>, but if possible get both the <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>. The <span style="color:green">UM24C</span> is a slightly older product feature-wise.<br />
<br />
The meter can be connected to power by plugging it into any one of the supported line inputs (see above; the different line options vary by model). Besides allowing for different connection options, there is a function within the UI to calculate the impedance of a cable by running a test first directly plugged in to a power supply, then unplugging and running again via the cable. Otherwise, line functionality is identical no matter which line input you choose.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Bluetooth ==<br />
<br />
Unlike most devices of this type, these communicate through serial-over-Bluetooth (RFCOMM); the manufacturer provides apps (for Android, Windows and Apple iOS; downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code. On the C models, the Bluetooth board is a separate layer that connects to the serial pads using pogo pins (<span style="color:green">UM24C</span>) or scissor-spring tension pins (<span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>). <span style="color:green">UM24C</span> has a generic open module board with a Beken BK3231 chipset. <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a shielded DX-BT18 module board (which should be compatible with HC-05/HC-06).<br />
<br />
There is no Enable pin passed between the Bluetooth board and the main board; the model name is (presumably) programmed into the module in Command mode at the factory, and the module is always in Data mode during normal operation. Communication between the boards is done at 9600 8-N-1.<br />
<br />
Note that this is specifically about the '''C''' models - the UM24, UM25 and UM34 are the exact same functionality but *without* Bluetooth communication. The UM25 and UM34 have pads which you could solder a TTL adapter to (if you disassemble the device) and get the same functionality. The UM24 has pads, but the firmware does not appear to support communication.<br />
<br />
== Protocol ==<br />
<br />
Approximately 500ms after applying power, the device sends 0xff. However, this is usually before a Bluetooth connection can be established, so the host end will likely never see it.<br />
<br />
1-byte commands are sent to the device, and in the case of 0xf0, the device responds with a 130-byte data dump of the current device status. All other commands return no acknowledgement.<br />
<br />
Each device (<span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>) has a similar command and response format, but the commands and responses vary slightly by device type. These variations are documented below. Unfortunately this means you will need to know what type of device you are communicating with to take full advantage of it.<br />
<br />
=== Commands to send ===<br />
<br />
Multiple commands may be sent at once; e.g. you could set the recording threshold to 0.28 A and rotate the screen by sending 0xccf2 immediately. An exception appears to be requesting the data dump; it doesn't seem to return the 130-byte response unless you wait a bit (approximately 0.2 seconds) after sending other commands.<br />

=== Unknown response fields ===<br />
<br />
Bytes 128+129 are not entirely known yet. They are believed to be stop markers.<br />
<br />
On <span style="color:green">UM24C</span> and <span style="color:blue">UM25C</span>, all observed units seem to be 0xfff1 so far.<br />
<br />
On <span style="color:darkorange">UM34C</span>, the last two bytes vary each time the device is polled. The values drift up and down over time, but will change completely after a device reset. For example:<br />
<br />

<br />
Samples 3 and 4 are identical, but were captured at different times. Samples 1 and 2 have two bytes different (44 -> 45 earlier and 01 -> 00 later) which should have an identical result if it were a simple sum, but result in 688c -> 688d. Samples 2 and 3 have two bytes different (14 -> 15 and 45 -> 46, a cumulative difference of 2), but both result in 688d. Samples 4 and 5 have one byte different (fe -> fc), but result in 688d -> 688f.<br />
<br />
All of these suggest some sort of "add if even or subtract if odd" iteration, but I haven't been able to find a process which results in the expected checksum differences.<br />
<br />
== Checksum (UM34C) ==<br />
The last byte of the packet is a checksum and can be calculated using the following Python snippet:<br />
<br />
<pre><br />
def checksum(pkt):<br />
positions = [<br />
1, 3, 7, 9, 15, 17, 19, 23, 31, 39, 41, 45, 49, 53, 55, 57, 59, 63,<br />
67, 69, 73, 79, 83, 89, 97, 99, 109, 111, 113, 119, 121, 127,<br />
]<br />
<br />
csum = 0<br />
for pos in positions:<br />
csum = csum ^ pkt[pos]<br />
return csum<br />
</pre><br />
<br />
Note: The checksum only covers odd bytes of the packet!<br />

<div>sigrok is intended as a flexible, cross-platform, and '''hardware-independent''' software suite, i.e., it supports various devices from many different vendors.<br />
<br />
Here is a list of currently supported devices (various stages of completeness) in the [http://sigrok.org/gitweb/?p=libsigrok.git;a=summary latest git version of libsigrok] (fewer devices might be supported in tarball releases) and devices we plan to support in the future.<br />
<br />
The lists are sorted by category ([[File:Nuvola OK.png|16px]] <span style="background-color: lime">supported</span>: [[:Category:Supported|{{PAGESINCATEGORY:Supported|pages}}]], [[File:Nuvola Orange.png|16px]] <span style="background-color: orange">in progress</span>: [[:Category:In progress|{{PAGESINCATEGORY:In progress|pages}}]], [[File:Nuvola Red.png|16px]] <span style="background-color: red">planned</span>: [[:Category:Planned|{{PAGESINCATEGORY:Planned|pages}}]]), and alphabetically within those categories.<br />

<br />
== What is it? ==<br />
<br />
The RDTech <span style="color:green">UM24C</span> (~$12 USD), <span style="color:blue">UM25C</span> (~$16 USD) and <span style="color:darkorange">UM34C</span> (~$18 USD) are USB load meters which can measure various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. They can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). They also allow graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
The <span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> are extremely similar, but have several differences:<br />
<br />
* <span style="color:green">UM24C</span> supports USB-A male / USB-microB female line, USB-A female load.<br />
* <span style="color:blue">UM25C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female / USB-C female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB 3.0 data passthrough; <span style="color:green">UM24C</span>/<span style="color:blue">UM25C</span> are USB 2.0 only.<br />
* <span style="color:blue">UM25C</span> displays and sends 1mV / 0.1mA live resolution, <span style="color:green">UM24C</span>/<span style="color:darkorange">UM34C</span> are 10mV / 1mA live resolution. Note that this is applicable for instantaneous view only; aggregates are the same for all three models.<br />
* <span style="color:green">UM24C</span> is maximum 3A current, <span style="color:darkorange">UM34C</span> is 4A, <span style="color:blue">UM25C</span> is 5A.<br />
* <span style="color:green">UM24C</span> only supports detection of unknown (normal) charging mode, QC2.0 and QC3.0, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> support detecting additional charging modes. This does not affect the line/load from negotiating a charging mode, just the meter's ability to detect it.<br />
* <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a switch which lets you turn on and off the Bluetooth functionality.<br />
* <span style="color:green">UM24C</span> is not supported by their Apple app, only <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>.<br />
<br />
The <span style="color:blue">UM25C</span> is the most fully featured of the three, but is missing USB 3.0 data passthrough (<span style="color:darkorange">UM34C</span> only). If you have to buy one, get the <span style="color:blue">UM25C</span>, but if possible get both the <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>. The <span style="color:green">UM24C</span> is a slightly older product feature-wise.<br />
<br />
The meter can be connected to power by plugging it into any one of the supported line inputs (see above; the different line options vary by model). Besides allowing for different connection options, there is a function within the UI to calculate the impedance of a cable by running a test first directly plugged in to a power supply, then unplugging and running again via the cable. Otherwise, line functionality is identical no matter which line input you choose.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Bluetooth ==<br />
<br />
Unlike most devices of this type, these communicate through serial-over-Bluetooth (RFCOMM); the manufacturer provides apps (for Android, Windows and Apple iOS; downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code. On the C models, the Bluetooth board is a separate layer that connects to the serial pads using pogo pins (<span style="color:green">UM24C</span>) or scissor-spring tension pins (<span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>). <span style="color:green">UM24C</span> has a generic open module board with a Beken BK3231 chipset. <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a shielded DX-BT18 module board (which should be compatible with HC-05/HC-06).<br />
<br />
There is no Enable pin passed between the Bluetooth board and the main board; the model name is (presumably) programmed into the module in Command mode at the factory, and the module is always in Data mode during normal operation. Communication between the boards is done at 9600 8-N-1.<br />
<br />
Note that this is specifically about the '''C''' models - the UM24, UM25 and UM34 are the exact same functionality but *without* Bluetooth communication. The UM25 and UM34 have pads which you could solder a TTL adapter to (if you disassemble the device) and get the same functionality. The UM24 has pads, but the firmware does not appear to support communication.<br />
<br />
== Protocol ==<br />
<br />
Approximately 500ms after applying power, the device sends 0xff. However, this is usually before a Bluetooth connection can be established, so the host end will likely never see it.<br />
<br />
1-byte commands are sent to the device, and in the case of 0xf0, the device responds with a 130-byte data dump of the current device status. All other commands return no acknowledgement.<br />
<br />
Each device (<span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>) has a similar command and response format, but the commands and responses vary slightly by device type. These variations are documented below. Unfortunately this means you will need to know what type of device you are communicating with to take full advantage of it.<br />
<br />
=== Commands to send ===<br />
<br />
Multiple commands may be sent at once; e.g. you could set the recording threshold to 0.28 A and rotate the screen by sending 0xccf2 immediately. An exception appears to be requesting the data dump; it doesn't seem to return the 130-byte response unless you wait a bit (approximately 0.2 seconds) after sending other commands.<br />

=== Unknown response fields ===<br />
<br />
Bytes 128+129 are not entirely known yet. They are believed to be stop markers.<br />
<br />
On <span style="color:green">UM24C</span> and <span style="color:blue">UM25C</span>, all observed units seem to be 0xfff1 so far.<br />
<br />
On <span style="color:darkorange">UM34C</span>, the last two bytes vary each time the device is polled. The values drift up and down over time, but will change completely after a device reset. For example:<br />
<br />

<br />
Samples 3 and 4 are identical, but were captured at different times. Samples 1 and 2 have two bytes different (44 -> 45 earlier and 01 -> 00 later) which should have an identical result if it were a simple sum, but result in 688c -> 688d. Samples 2 and 3 have two bytes different (14 -> 15 and 45 -> 46, a cumulative difference of 2), but both result in 688d. Samples 4 and 5 have one byte different (fe -> fc), but result in 688d -> 688f.<br />
<br />
All of these suggest some sort of "add if even or subtract if odd" iteration, but I haven't been able to find a process which results in the expected checksum differences.<br />
<br />
== Checksum (UM34C) ==<br />
The last byte of the packet is a checksum and can be calculated using the following Python snippet:<br />
<br />
<pre><br />

== What is it? ==<br />
<br />
The RDTech <span style="color:green">UM24C</span> (~$12 USD), <span style="color:blue">UM25C</span> (~$16 USD) and <span style="color:darkorange">UM34C</span> (~$18 USD) are USB load meters which can measure various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. They can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). They also allow graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
The <span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> are extremely similar, but have several differences:<br />
<br />
* <span style="color:green">UM24C</span> supports USB-A male / USB-microB female line, USB-A female load.<br />
* <span style="color:blue">UM25C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female / USB-C female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB 3.0 data passthrough; <span style="color:green">UM24C</span>/<span style="color:blue">UM25C</span> are USB 2.0 only.<br />
* <span style="color:blue">UM25C</span> displays and sends 1mV / 0.1mA live resolution, <span style="color:green">UM24C</span>/<span style="color:darkorange">UM34C</span> are 10mV / 1mA live resolution. Note that this is applicable for instantaneous view only; aggregates are the same for all three models.<br />
* <span style="color:green">UM24C</span> is maximum 3A current, <span style="color:darkorange">UM34C</span> is 4A, <span style="color:blue">UM25C</span> is 5A.<br />
* <span style="color:green">UM24C</span> only supports detection of unknown (normal) charging mode, QC2.0 and QC3.0, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> support detecting additional charging modes. This does not affect the line/load from negotiating a charging mode, just the meter's ability to detect it.<br />
* <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a switch which lets you turn on and off the Bluetooth functionality.<br />
* <span style="color:green">UM24C</span> is not supported by their Apple app, only <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>.<br />
<br />
The <span style="color:blue">UM25C</span> is the most fully featured of the three, but is missing USB 3.0 data passthrough (<span style="color:darkorange">UM34C</span> only). If you have to buy one, get the <span style="color:blue">UM25C</span>, but if possible get both the <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>. The <span style="color:green">UM24C</span> is a slightly older product feature-wise.<br />
<br />
The meter can be connected to power by plugging it into any one of the supported line inputs (see above; the different line options vary by model). Besides allowing for different connection options, there is a function within the UI to calculate the impedance of a cable by running a test first directly plugged in to a power supply, then unplugging and running again via the cable. Otherwise, line functionality is identical no matter which line input you choose.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Bluetooth ==<br />
<br />
Unlike most devices of this type, these communicate through serial-over-Bluetooth (RFCOMM); the manufacturer provides apps (for Android, Windows and Apple iOS; downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code. On the C models, the Bluetooth board is a separate layer that connects to the serial pads using pogo pins (<span style="color:green">UM24C</span>) or scissor-spring tension pins (<span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>). <span style="color:green">UM24C</span> has a generic open module board with a Beken BK3231 chipset. <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a shielded DX-BT18 module board (which should be compatible with HC-05/HC-06).<br />
<br />
There is no Enable pin passed between the Bluetooth board and the main board; the model name is (presumably) programmed into the module in Command mode at the factory, and the module is always in Data mode during normal operation. Communication between the boards is done at 9600 8-N-1.<br />
<br />
Note that this is specifically about the '''C''' models - the UM24, UM25 and UM34 are the exact same functionality but *without* Bluetooth communication. The UM25 and UM34 have pads which you could solder a TTL adapter to (if you disassemble the device) and get the same functionality. The UM24 has pads, but the firmware does not appear to support communication.<br />
<br />
== Protocol ==<br />
<br />
Approximately 500ms after applying power, the device sends 0xff. However, this is usually before a Bluetooth connection can be established, so the host end will likely never see it.<br />
<br />
1-byte commands are sent to the device, and in the case of 0xf0, the device responds with a 130-byte data dump of the current device status. All other commands return no acknowledgement.<br />
<br />
Each device (<span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>) has a similar command and response format, but the commands and responses vary slightly by device type. These variations are documented below. Unfortunately this means you will need to know what type of device you are communicating with to take full advantage of it.<br />
<br />
=== Commands to send ===<br />
<br />
Multiple commands may be sent at once; e.g. you could set the recording threshold to 0.28 A and rotate the screen by sending 0xccf2 immediately. An exception appears to be requesting the data dump; it doesn't seem to return the 130-byte response unless you wait a bit (approximately 0.2 seconds) after sending other commands.<br />

=== Unknown response fields ===<br />
<br />
Bytes 128+129 are not entirely known yet. They are believed to be stop markers.<br />
<br />
On <span style="color:green">UM24C</span> and <span style="color:blue">UM25C</span>, all observed units seem to be 0xfff1 so far.<br />
<br />
On <span style="color:darkorange">UM34C</span>, the last two bytes vary each time the device is polled. The values drift up and down over time, but will change completely after a device reset. For example:<br />
<br />

<br />
Samples 3 and 4 are identical, but were captured at different times. Samples 1 and 2 have two bytes different (44 -> 45 earlier and 01 -> 00 later) which should have an identical result if it were a simple sum, but result in 688c -> 688d. Samples 2 and 3 have two bytes different (14 -> 15 and 45 -> 46, a cumulative difference of 2), but both result in 688d. Samples 4 and 5 have one byte different (fe -> fc), but result in 688d -> 688f.<br />
<br />
All of these suggest some sort of "add if even or subtract if odd" iteration, but I haven't been able to find a process which results in the expected checksum differences.<br />
<br />
== Checksum (UM34C) ==<br />
The last byte of the packet is a checksum and can be calculated using the following Python snippet:<br />
<br />
<pre><br />
def checksum(pkt):<br />

<br />
== What is it? ==<br />
<br />
The RDTech <span style="color:green">UM24C</span> (~$12 USD), <span style="color:blue">UM25C</span> (~$16 USD) and <span style="color:darkorange">UM34C</span> (~$18 USD) are USB load meters which can measure various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. They can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). They also allow graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
The <span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> are extremely similar, but have several differences:<br />
<br />
* <span style="color:green">UM24C</span> supports USB-A male / USB-microB female line, USB-A female load.<br />
* <span style="color:blue">UM25C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female / USB-C female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB 3.0 data passthrough; <span style="color:green">UM24C</span>/<span style="color:blue">UM25C</span> are USB 2.0 only.<br />
* <span style="color:blue">UM25C</span> displays and sends 1mV / 0.1mA live resolution, <span style="color:green">UM24C</span>/<span style="color:darkorange">UM34C</span> are 10mV / 1mA live resolution. Note that this is applicable for instantaneous view only; aggregates are the same for all three models.<br />
* <span style="color:green">UM24C</span> is maximum 3A current, <span style="color:darkorange">UM34C</span> is 4A, <span style="color:blue">UM25C</span> is 5A.<br />
* <span style="color:green">UM24C</span> only supports detection of unknown (normal) charging mode, QC2.0 and QC3.0, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> support detecting additional charging modes. This does not affect the line/load from negotiating a charging mode, just the meter's ability to detect it.<br />
* <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a switch which lets you turn on and off the Bluetooth functionality.<br />
* <span style="color:green">UM24C</span> is not supported by their Apple app, only <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>.<br />
<br />
The <span style="color:blue">UM25C</span> is the most fully featured of the three, but is missing USB 3.0 data passthrough (<span style="color:darkorange">UM34C</span> only). If you have to buy one, get the <span style="color:blue">UM25C</span>, but if possible get both the <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>. The <span style="color:green">UM24C</span> is a slightly older product feature-wise.<br />
<br />
The meter can be connected to power by plugging it into any one of the supported line inputs (see above; the different line options vary by model). Besides allowing for different connection options, there is a function within the UI to calculate the impedance of a cable by running a test first directly plugged in to a power supply, then unplugging and running again via the cable. Otherwise, line functionality is identical no matter which line input you choose.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Bluetooth ==<br />
<br />
Unlike most devices of this type, these communicate through serial-over-Bluetooth (RFCOMM); the manufacturer provides apps (for Android, Windows and Apple iOS; downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code. On the C models, the Bluetooth board is a separate layer that connects to the serial pads using pogo pins (<span style="color:green">UM24C</span>) or scissor-spring tension pins (<span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>). <span style="color:green">UM24C</span> has a generic open module board with a Beken BK3231 chipset. <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a shielded DX-BT18 module board (which should be compatible with HC-05/HC-06).<br />
<br />
There is no Enable pin passed between the Bluetooth board and the main board; the model name is (presumably) programmed into the module in Command mode at the factory, and the module is always in Data mode during normal operation. Communication between the boards is done at 9600 8-N-1.<br />
<br />
Note that this is specifically about the '''C''' models - the UM24, UM25 and UM34 are the exact same functionality but *without* Bluetooth communication. The UM25 and UM34 have pads which you could solder a TTL adapter to (if you disassemble the device) and get the same functionality. The UM24 has pads, but the firmware does not appear to support communication.<br />
<br />
== Protocol ==<br />
<br />
Approximately 500ms after applying power, the device sends 0xff. However, this is usually before a Bluetooth connection can be established, so the host end will likely never see it.<br />
<br />
1-byte commands are sent to the device, and in the case of 0xf0, the device responds with a 130-byte data dump of the current device status. All other commands return no acknowledgement.<br />
<br />
Each device (<span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>) has a similar command and response format, but the commands and responses vary slightly by device type. These variations are documented below. Unfortunately this means you will need to know what type of device you are communicating with to take full advantage of it.<br />
<br />
=== Commands to send ===<br />
<br />
Multiple commands may be sent at once; e.g. you could set the recording threshold to 0.28 A and rotate the screen by sending 0xccf2 immediately. An exception appears to be requesting the data dump; it doesn't seem to return the 130-byte response unless you wait a bit (approximately 0.2 seconds) after sending other commands.<br />

=== Unknown response fields ===<br />
<br />
Bytes 128+129 are not entirely known yet. They are believed to be stop markers.<br />
<br />
On <span style="color:green">UM24C</span> and <span style="color:blue">UM25C</span>, all observed units seem to be 0xfff1 so far.<br />
<br />
On <span style="color:darkorange">UM34C</span>, the last two bytes vary each time the device is polled. The values drift up and down over time, but will change completely after a device reset. For example:<br />
<br />

<br />
Samples 3 and 4 are identical, but were captured at different times. Samples 1 and 2 have two bytes different (44 -> 45 earlier and 01 -> 00 later) which should have an identical result if it were a simple sum, but result in 688c -> 688d. Samples 2 and 3 have two bytes different (14 -> 15 and 45 -> 46, a cumulative difference of 2), but both result in 688d. Samples 4 and 5 have one byte different (fe -> fc), but result in 688d -> 688f.<br />
<br />
All of these suggest some sort of "add if even or subtract if odd" iteration, but I haven't been able to find a process which results in the expected checksum differences.<br />
<br />
== Checksum (UM34C) ==<br />
The last byte of the packet is a checksum and can be calculated using the following Python snippet:<br />
<br />
<pre><br />
def checksum(pkt):<br />

== What is it? ==<br />
<br />
The RDTech <span style="color:green">UM24C</span> (~$12 USD), <span style="color:blue">UM25C</span> (~$16 USD) and <span style="color:darkorange">UM34C</span> (~$18 USD) are USB load meters which can measure various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. They can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). They also allow graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
The <span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> are extremely similar, but have several differences:<br />
<br />
* <span style="color:green">UM24C</span> supports USB-A male / USB-microB female line, USB-A female load.<br />
* <span style="color:blue">UM25C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female / USB-C female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB-A male / USB-microB female / USB-C female line, USB-A female load.<br />
* <span style="color:darkorange">UM34C</span> supports USB 3.0 data passthrough; <span style="color:green">UM24C</span>/<span style="color:blue">UM25C</span> are USB 2.0 only.<br />
* <span style="color:blue">UM25C</span> displays and sends 1mV / 0.1mA live resolution, <span style="color:green">UM24C</span>/<span style="color:darkorange">UM34C</span> are 10mV / 1mA live resolution. Note that this is applicable for instantaneous view only; aggregates are the same for all three models.<br />
* <span style="color:green">UM24C</span> is maximum 3A current, <span style="color:darkorange">UM34C</span> is 4A, <span style="color:blue">UM25C</span> is 5A.<br />
* <span style="color:green">UM24C</span> only supports detection of unknown (normal) charging mode, QC2.0 and QC3.0, <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> support detecting additional charging modes. This does not affect the line/load from negotiating a charging mode, just the meter's ability to detect it.<br />
* <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a switch which lets you turn on and off the Bluetooth functionality.<br />
* <span style="color:green">UM24C</span> is not supported by their Apple app, only <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>.<br />
<br />
The <span style="color:blue">UM25C</span> is the most fully featured of the three, but is missing USB 3.0 data passthrough (<span style="color:darkorange">UM34C</span> only). If you have to buy one, get the <span style="color:blue">UM25C</span>, but if possible get both the <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span>. The <span style="color:green">UM24C</span> is a slightly older product feature-wise.<br />
<br />
The meter can be connected to power by plugging it into any one of the supported line inputs (see above; the different line options vary by model). Besides allowing for different connection options, there is a function within the UI to calculate the impedance of a cable by running a test first directly plugged in to a power supply, then unplugging and running again via the cable. Otherwise, line functionality is identical no matter which line input you choose.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Bluetooth ==<br />
<br />
Unlike most devices of this type, these communicate through serial-over-Bluetooth (RFCOMM); the manufacturer provides apps (for Android, Windows and Apple iOS; downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code. On the C models, the Bluetooth board is a separate layer that connects to the serial pads using pogo pins (<span style="color:green">UM24C</span>) or scissor-spring tension pins (<span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>). <span style="color:green">UM24C</span> has a generic open module board with a Beken BK3231 chipset. <span style="color:blue">UM25C</span> and <span style="color:darkorange">UM34C</span> have a shielded DX-BT18 module board (which should be compatible with HC-05/HC-06).<br />
<br />
There is no Enable pin passed between the Bluetooth board and the main board; the model name is (presumably) programmed into the module in Command mode at the factory, and the module is always in Data mode during normal operation. Communication between the boards is done at 9600 8-N-1.<br />
<br />
Note that this is specifically about the '''C''' models - the UM24, UM25 and UM34 are the exact same functionality but *without* Bluetooth communication. The UM25 and UM34 have pads which you could solder a TTL adapter to (if you disassemble the device) and get the same functionality. The UM24 has pads, but the firmware does not appear to support communication.<br />
<br />
== Protocol ==<br />
<br />
Approximately 500ms after applying power, the device sends 0xff. However, this is usually before a Bluetooth connection can be established, so the host end will likely never see it.<br />
<br />
1-byte commands are sent to the device, and in the case of 0xf0, the device responds with a 130-byte data dump of the current device status. All other commands return no acknowledgement.<br />
<br />
Each device (<span style="color:green">UM24C</span>, <span style="color:blue">UM25C</span>, <span style="color:darkorange">UM34C</span>) has a similar command and response format, but the commands and responses vary slightly by device type. These variations are documented below. Unfortunately this means you will need to know what type of device you are communicating with to take full advantage of it.<br />
<br />
=== Commands to send ===<br />
<br />
Multiple commands may be sent at once; e.g. you could set the recording threshold to 0.28 A and rotate the screen by sending 0xccf2 immediately. An exception appears to be requesting the data dump; it doesn't seem to return the 130-byte response unless you wait a bit (approximately 0.2 seconds) after sending other commands.<br />

=== Unknown response fields ===<br />
<br />
Bytes 128+129 are not entirely known yet. They are believed to be stop markers.<br />
<br />
On <span style="color:green">UM24C</span> and <span style="color:blue">UM25C</span>, all observed units seem to be 0xfff1 so far.<br />
<br />
On <span style="color:darkorange">UM34C</span>, the last two bytes vary each time the device is polled. The values drift up and down over time, but will change completely after a device reset. For example:<br />
<br />

Samples 3 and 4 are identical, but were captured at different times. Samples 1 and 2 have two bytes different (44 -> 45 earlier and 01 -> 00 later) which should have an identical result if it were a simple sum, but result in 688c -> 688d. Samples 2 and 3 have two bytes different (14 -> 15 and 45 -> 46, a cumulative difference of 2), but both result in 688d. Samples 4 and 5 have one byte different (fe -> fc), but result in 688d -> 688f.<br />
<br />
All of these suggest some sort of "add if even or subtract if odd" iteration, but I haven't been able to find a process which results in the expected checksum differences.<br />

== What is it? ==<br />
<br />
A ~$13 USB load meter; it measures various properties for USB devices including their voltage, amperage, wattage, resistance, capacity, temperature, data line voltage, and charging mode. It can track up to 11 groups of mAh/mWh capacity data, one of which is ephemeral (and disappears after replugging the device), nine of which are persistent until cleared, and one of which whose recording is only activated above a certain current threshold (and which can be recorded in parallel with any of the other 10 data groups). It also allows graphing the amperage and voltage over time, on the device's display itself, as well as rotating the display contents into any orientation.<br />
<br />
Unlike most devices of this type, this one communicates through serial-over-Bluetooth; the manufacturer provides apps (for Android and Windows, downloads including device documentation [https://www.mediafire.com/folder/0jt6xx2cyn7jt/UM24 here]), but not protocol documentation nor source code.<br />
<br />
Note that this is specifically about the UM24'''C''' - the UM24 is the version *without* Bluetooth communication, although it's unclear whether the serial pads are still exposed and functional on that model. On the C model, the Bluetooth board is a separate layer (using an off-the-shelf serial-to-Bluetooth module) that connects to the serial pads using pogo pins.<br />
<br />
The manufacturer has indicated that the firmware is not designed to be upgradeable and doesn't provide updates; nevertheless, the SWIM pin for the on-board STM8 chip is exposed, as are the other necessary pins for STM8 debugging. It's unclear whether the chip will allow eg. dumping, though.<br />
<br />
The load meter can be connected either by plugging it in directly using its USB male plug end, or by connecting it using a cable and the micro-USB port on top. These are functionally equivalent; in both cases, both power and data are passed through and measured in the same way. I've not observed any difference in measurements between these two modes of operation.<br />
<br />
It's unclear whether measurement of data lines is accurate enough to theoretically be used as a logic analyzer, but given the strange stability of the values during testing (unlike the voltage on the power lines) and the low-end STM8 chip, I suspect it's not.<br />
<br />
== Protocol ==<br />
<br />
Clearer documentation (as well as a JS implementation of the protocol) are coming soon, but below are my rough notes of the protocol, that I've figured out by reverse-engineering the Android application. The device won't auto-send any data; you're expected to send F0 any time you want new data, eg. on a timed loop.<br />
<br />
<pre><br />
All data returned by the device consists of measurements and configuration status, in 130-byte chunks. To my knowledge, it will never send any other data. All bytes below are displayed in hex format; every command is a single byte.<br />
<br />
# Commands to send:<br />
F0 - Request new data dump; this triggers a 130-byte response<br />
F1 - (device control) Go to next screen<br />
F2 - (device control) Rotate screen<br />
F3 - (device control) Switch to next data group<br />
F4 - (device control) Clear data group<br />
Bx - (configuration) Set recording threshold to a value between 0.00 and 0.15 A (where 'x' in the byte is 4 bits representing the value after the decimal point, eg. B7 to set it to 0.07 A)<br />
Cx - (configuration) Same as Bx, but for when you want to set it to a value between 0.16 and 0.30 A (16 subtracted from the value behind the decimal point, eg. 0.19 A == C3)<br />
Dx - (configuration) Set device backlight level; 'x' must be between 0 and 5 (inclusive)<br />
Ex - (configuration) Set screen timeout ('screensaver'); 'x' is in minutes and must be between 0 and 9 (inclusive), where 0 disables the screensaver<br />
<br />
# Response format:<br />
All byte offsets are in decimal, and inclusive. All values are big-endian and unsigned.<br />
0 - 1 Start marker (always 0x0963)<br />
2 - 3 Voltage (in mV, divide by 1000 to get V)<br />
4 - 5 Amperage (in mA, divide by 1000 to get A)<br />
6 - 9 Wattage (in mW, divide by 1000 to get W)<br />
10 - 11 Temperature (in celsius)<br />
12 - 13 Temperature (in fahrenheit)<br />
14 Unknown (not used in app)<br />
15 Currently selected data group<br />
16 - 95 Array of main capacity data groups (where the first one, group 0, is the ephemeral one)<br />
-- for each data group: 4 bytes mAh, 4 bytes mWh<br />
96 - 97 USB data line voltage (positive) in centivolts (divide by 100 to get V)<br />
98 - 99 USB data line voltage (negative) in centivolts (divide by 100 to get V)<br />
100 Charging mode; this is an enum, where 0 = unknown/standard, 1 = QC2.0, and presumably 2 = QC3.0 (but I haven't verified this)<br />
101 Unknown (not used in app)<br />
102 - 105 mAh from threshold-based recording<br />
106 - 109 mWh from threshold-based recording<br />
110 - 111 Currently configured threshold for recording<br />
112 - 115 Duration of recording, in seconds since start<br />
116 Recording active (1 if recording)<br />
117 Unknown (not used in app)<br />
118 - 119 Current screen timeout setting<br />
120 - 121 Current backlight setting<br />
122 - 125 Resistance in deci-ohms (divide by 10 to get ohms)<br />
126 Unknown<br />
127 Current screen (same order as on device)<br />
128 - 129 Stop marker (always 0xfff1)<br />
