Thanks for your elaborate explanation...

possible actions I can think of

  • Can you check with a voltmeter if the GROUNDS are connected, so the electronics share a common reference?

  • Does the RS232 connect really need the TTL level convertor? is the RS232 12V
    if the voltages get too low, communications fail.

  • Connect the laptop and use an Arduino as sniffer?
