Relay Station RS422 Pin-outs
The RF Relay Stations are connected by twisted pair wire -- use Belden 1227A1, Cat 5 wire or equivalent.
The Relay Port on the Base Station and the Relay Port on the Relay Station are connected with a straight
cable using the following pin-outs:
Base Connector Pin # Relay Connector
Receive Data + 5 Transmit Data +
Receive Data - 6 Transmit Data -
Transmit Data + 2 Receive Data +
Transmit Data - 3 Receive Data -
Make a cable with 5-5, 6-6, 2-2, and 3-3 (a straight cable); but, be careful that you select wires so that the 2
wire is in the twisted pair with the 3 wire, and the 5 wire is in the twisted pair with the 6 wire.
For all RJ Cable pin numbers, number from left to right with the metal pin side of the connector facing you
and the cable running to the down position.
