Team,
Could you please help with the below request?
This card is not functioning as expected:
-Board powered by 5V (V+ is approximately 5V and V- is -3V).
-we configured it in mode 001 (RS232) and looped L2 back to L3.
See attached pics of card configuration and oscilloscope measurement with R2 on channel 1 and R3 on channel 3.
-Why don't we see the same signal on both channels?
We ultimately want to power the board with 3.3V, but then we measure V+ at 3.2V and V- at 700mV.
-Is this behavior expected?
Thanks in advance,
Anber
