Hi Standard generic drill:
1) Swap RX and TX (or check with a voltmeter) 2) Cycle through the normal set of baud rates 3) Double check the jumpers on the 422 to 232 conversion 4) Check with a terminal program, typing in the *IDN? query by hand Yes it’s sort of a mix and match of what’s above. The order is purely a “what I usually mess up” sequence.
