Hardware Setup

This chapter describes right, left, and front panel features; basic front panel operation; and how to connect cables to the

MLC 104 IP Plus controller.

Right Side Panel Features and Connections

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

B	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

A	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.

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.

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