Display control RS-232 /IR port — This port has dedicated
bidirectional RS-232 and infrared signal output.
From this port, commands sent from a driver or user-defined
command strings (entered via the Global Configurator) can be
sent to the display device.
For bidirectional RS-232 communication, the transmit, ground,
and receive pins must be wired at both the controller and the
projector connectors, as shown below.

For infrared (IR) output, wire an IR Emitter (2 emitters are the
maximum), as shown below, for a modulated signal and ground.

COMM Link — You can connect up to four Extron control
modules (IRCMs, ACMs, RCMs, CMs), one Extron IR signal
repeater (IRL 20 or IR Link), and/or two Extron SCP 104 control
pads to this port to allow remote control of the MLC 104 IP Plus
controller or other items. A maximum of seven devices can be
connected to this port.
The SCP 104 replicates the MLC's front panel controls. The
IR signal repeater can receive IR signals from an optional IR 402
remote control and send them to the controller. Once the MLC
is set up, control modules can be used to control VCRs, DVD
players, tape decks, a projector lift, or screen control. For device
control, refer to the appropriate device's user's manual.
The control modules, IR signal repeaters, and SCPs can be daisy
chained, as shown on the following page. Extron Comm-Link
(CTL and CTLP) cable is recommended for these connections.

When an SCP 104 is connected to an MLC 104 IP Plus,
the SCP's DIP switch #4 must be in the ON (up) position.
