You can do this with linux without any tools. I'm running Ubuntu 20 on my laptop. A simple echo will suffice.


--- Code: ---root@grexps:/home/greg/python-usbtmc#  echo "*IDN?" > /dev/usbtmc0; cat /dev/usbtmc0
RIGOL TECHNOLOGIES,DL3021A,DL3A19xxxx,00.01.04.00root@grexps:/home/greg/python-usbtmc#
root@grexps:/home/greg/python-usbtmc#
root@grexps:/home/greg/python-usbtmc# echo ":PROJ:SET MODEL,DL3031A" > /dev/usbtmc0; cat /dev/usbtmc0
OK
cat: /dev/usbtmc0: Connection timed out
root@grexps:/home/greg/python-usbtmc#

I have the DP832 hacked to DP832A.  I went to the IP address expecting to see a way to see/change the power supply settings.  That is some type of UI that replaces front panel much like the Rigol O-scope has. 

I was wondering if anyone else was missing this feature?  Is it worth doing a node.js project to add this? If we did come up with a UI how much trouble would it be to have the power supply host the web page?
Remek:
Do you know if it is possible to hack the new dp900 series?

I did this on a Raspberry Pi, where the USB serial device also showed up as /dev/usbtmc0 on Raspian 11, with a kernel reporting itself as

Linux pigps 5.15.32-v7l+ #1538 SMP Thu Mar 31 19:39:41 BST 2022 armv7l

This approach worked really great, thanks!

Is there any possibility that this method works on the new DP932E/DP932U models?
