On a Fanuc DR usually refers to the signal on pin 6 of both 25pin and 9 pin D connectors, if you have the hardware handshake jumpered out, this should be 6,8 & 20 jumpered out on a 25pin.
Otherwise with handshake connected DR usually connects to ER on the oposite end.
ER is 4 on 9pin & 20 on a 25pin.
