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. See chapter two and
refer to the MediaLink Control Program or the
MediaLink Controllers User’s Manual for details.
Each control module fits into a double-space high area (1.4” H x
3.5” W) in an Extron Architectural Adapter Plate, interface, or
distribution amplifier.
The relay control modules toggle relays within a MediaLink
Controller to operate controls for various items in a room (such
as a screen control or a light switch). The RCM-SC controls the
movement of a projection screen. The RCM-SCLT controls up/
down screen movement and also lighting. In this manual Relay
Control Modules are referred to as “modules”, “RCMs”, or
“control modules” when instructions apply to more than one
model.
Features
Grey, black, or white faceplates — The control modules are
offered in three shades for integration into a variety of
environments.
System expandability — Up to four control modules (RCMs,
infrared control modules/IRCMs, audio control modules/
ACMs) can be daisy chained together in any combination
and connected to a MediaLink Controller to provide basic
A/V source and room control from several locations.
Furniture and wall mountability — The control modules can be
mounted onto or in furniture or walls if they are installed
in optional mounting plates (AAP 102, AAP 104) or in the
MediaLink Controller’s accessory faceplates.
