Epson MLC 104 IP Plus Benutzerhandbuch

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.

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.

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, 

must be in the ON (up) position.

  The SCP 104 must have firmware version 1.01 or
