As I understand 120 Ohm terminated resistor for RS485 bus will be used only in one single end of the bus. I wonder if RS485T integrate R120 ohm and we connect many of them together, the data might be incorrect. I test with AC Plug if I don't use the RS485T the RX response is correct as in attached picture. After testing AC Socket for a while I found that if there is only one 120 Ohm terminate resistor on the bus, sometimes the Rx response is incorrect.
Anyone face the same problem?
