You are looking at the RS-485-side of an RS-232/RS-485 converter and the power supply voltage for the converter is +5V. Under idle conditions (no transmission), and assuming you have enabled the RS-485 output: what would you expect at: (a) Output A measured against output B (b) Output A measured against ground (c) Output B measured against ground
