My customer is trying to verify the Apin and Bpin voltages in the final test.
However, the datasheet only describes differential voltage.
Since RS485 is a differential voltage, could you tell me how many volts it should be at (A-B) to be as per the datasheet?
Please tell me what voltage would be for each combination for Dpin and DEpin?
The termination resistor is 120 Ω between A and B near the device.
And, no road.
