RS-485 Link to Operator Interface
The RS-485 port is located below the hinged plastic cover on the top part of the Controller Module.
Typically, the cable that interconnects this port to the Operator Interface must be fabricated during
installation, because it will probably be necessary to run the cable through conduit.
