RS485 Tranceiver IC's RX Pin - E1.20 RDM (Remote Device Management) Protocol Forums

I would suggest putting a scope on the line and use the Transmitter Enable line as the scope trigger. This way you can accurately measure the timing of what is occurring on the wire to see how much delay there is from the end of the request to the beginning of your response. Also if after you respond you want to make sure you aren't holding in transmit too long that you aren't missing the next request from the controller.
