About this Manual
This manual documents four types of control modules: 
Infrared Control Modules (IRCMs), Audio Control Modules 
(ACMs), Relay Control Modules (RCMs), and basic Control 
Modules (CMs). Unless otherwise specified, in this manual 
Control Modules are referred to as “modules”, “IRCMs”, 
“ACMs”, "RCMs", " CMs", and “control modules” when 
instructions apply to more than one model 
About the Control Modules
Extron Control Modules are hardwired remote control keypads 
for use with Extron MediaLink Controllers, System 5 IP series 
switchers, or any Secondary Control Panel (SCP) model. The 
logic (RS-232, IR, etc.) for these keypads resides in the MLC or 
System 5 IP units. 
N  Setup and selected command learning must be done via 
RS-232 or IP, and learned commands are stored in the 
MLC or System 5 IP. For programming and operation, 
refer to the MediaLink Control Program or the relevant 
System 5 IP, SCP, or MediaLink Controllers user’s 
manuals for details.
Each control module fits into a double space high or four 
space high opening (depending on the model) in an Extron 
Architectural Adapter Plate, interface, or distribution amplifier.
IRCM control modules replicate source device front panel 
controls (such as on a VCR or DVD player) and uses infrared 
commands to control those devices. ACM models replicate 
some MediaLink Switcher front panel controls. RCM models 
toggle relays within a System 5 IP or MediaLink controller. CM-
19AC remotely controls audio conference systems.
Features
Color options — The control modules come in black, white, or 
RAL9010 for integration into a variety of environments. 
System expandability — Up to four control modules can be 
daisy-chained together in any combination and connected 
to an MLC 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 MLC’s accessory faceplates.
Flexibility — You choose what infrared commands or controls 
to associate with each button on a control module.
