  Programmable buttons — You can program these buttons to 
control any IR-controllable device, or you can have RS-232 
codes or relays assigned to each button. Button labels for use 
with the CM-xBLB modules are available with your controller 
(MLC, System 5 IP, etc.). The metal on the CM-xBB modules can 
be engraved.

Setting Up the Buttons 
(IRCM, RCM, and CM Modules Only)
Before the control module can control a device such as a VCR 
or a DVD player, you must connect the module to an MLC or 
System 5 IP, and then configure each button. Refer to the MLC, 
System 5 IP, or Configuration software user’s manuals.
N
  Once the MLC, or System 5 IP and control modules have 
been set up, pressing a button on the control module 
causes a command to be sent out, regardless of whether 
the display/projector’s power is on or off. Also, it is not 
possible to separately control two or more identical 
devices out of a single IR port.
Mounting the Control Module into an AAP Wall 
Plate or Device Faceplate
The control module and any adapter plates must be attached 
to a device faceplate or AAP wall plate and cabled before it is 
installed in a wall or furniture. The installation screws are built 
into its front panel, so no additional screws are needed. 
1.
  Before attaching any cables, insert the module’s screws 
into the holes in the device’s faceplate or AAP wall plate. 
Secure the control module to the faceplate/wall plate with 
the provided captive washers and #4-40 nuts.
2.  Follow the “Installation Overview” section of this chapter.
