Introduction About the Relay Control Modules The Extron Relay Control Modules (RCMs) are hard-wired remote control keypads designed for use with the Extron MediaLink Controller (MLC). Refer to the MediaLink Controllers User’s Manual for information on installing, operating, and setting up the controller. All setup must be done via RS-232.
Installation and Operation Installation Overview Installation and service must be performed by CAUTION authorized personnel only. These products should be used with UL approved electrical boxes. See “UL Requirements”, page 2-3. To install and set up Relay Control Modules, follow these steps: Turn the equipment off.
Installation and Operation, cont’d Rear Panel Connectors and Switches The same type and quantity of connectors and DIP switches shown above can be found on the rear panels of all models of the control modules. Communications connectors — Use these connectors to connect control modules together and to connect them to the MLC and to an optional IR Link infrared repeater.
