The '''eTommens eTM-xxxxP''' series are 1 channel switch-mode programmable DC power supplies with both USB/serial and RS232 connectivity.

The devices are also sold as rebranded versions by e.g. [[Hanmatek_HM305P|Hanmatek]] and Rockseed.

'''Note:''' libsigrok support for these devices is pending the merge of this PR - https://github.com/sigrokproject/libsigrok/pull/100

'''Note:''' The libsigrok driver needs to know about the device's class and model, retrievable with [https://github.com/markrages/py_test_interface hm305.py] please let us know.

== Protocol ==

Modbus RTU only function codes 0x03 and 0x06 are supported (according to the pdf that came with the device).([https://en.wikipedia.org/wiki/Modbus#Frame_formats Wikipedia]). Baudrate defaults to 9600, 1 start bit, 8 data bits, no checkbits and 1 stop bit. Registers are 16bits, bigendian.

1. There is actually no OPP button on the power supply, but the protocol documentation lists, the address for it. Not relevant at the moment for a driver, since sigrok seems to have no OPP support anyway.
2. In the protocol documentation there is no mention of how to set the presets M1 to M6. But it seems they start at address 0x1000. This needs to be researched still, but I currently do not know how to handle presets in sigrok, so I need to find that out too.
Also there is some other addresses listed in config files that are with the software provided, these need to be researched too.

3. The Protection State registers contains looks as follow and the designated bit goes high if the protection state is active:

the 2nd byte does not give any information, and seems to always be 0.

4. The decimals registers contains the the decimal information for Voltage, Current and Power. The lower 12 bits are used with 4bits for each value. If the register content is 0x0321, it means Voltage has 3 decimals, Current 2 and Power 1.
