RS-485 Communications Connector
This connector provides the connection point for the Local Loop RS-485 communications
loop. The wiring consists of a twisted pair of wires with a shield.
T - RS485 (+) Communications terminal
SHLD - Common return wire, this point is internally tied to GND on the
CV Controller.
R - RS485 (-) Communications terminal
