Relay Control Modules
All IR control signals are sent to all devices (video
sources, projector, etc.) at the same time even if two or
three IR Emitters or an IR Broadcaster are installed. The
IR sending devices share the same IR Display/Control
port on the MLC.
• For RCM modules, ensure that the wiring from
the MLC to the screen motor’s low voltage
controller is correct. Refer to the screen
manufacturer’s user’s guides. For the
RCM-SCLT, ensure that the wiring from the MLC
to the AC power controller is correct for the
model you are using.
5. Call the Extron S3 Sales and Technical Support Hotline if
the item(s) being controlled still does (do) not respond
when the control module’s buttons are pressed.

Mounting the Control Module Into an AAP
Wallplate or Device Faceplate
The control module and any other adapter plates must be
attached to a device faceplate or AAP wallplate and cabled
before the device or wallplate is installed in a wall or furniture.
The screws needed for installing the control module are built
into its front panel, so no additional screws will be needed.
1. Before any cables are attached, insert the control module’s
screws through the holes in the device’s faceplate or AAP
wallplate. Secure the control module to the faceplate/
wallplate with the provided captive washers and #4-40
nuts.
2. Follow steps
5
through
12
in the “Installation Overview”
section of this chapter.
3. If the control module is not installed into a grounded metal wall
box, ground the faceplate before fastening the faceplate
into the wall or furniture.
Do not tie a module’s faceplate to both a separate earth
ground and the circuit ground (via a connector pin). If
you tie a product to two different ground sources, you
may introduce ground loops or other grounding-related
problems into the system.
