Epson MLC 104 IP Plus Benutzerhandbuch

There are several features that must be set up prior to using the 

MLC.  Refer to chapter 4 in the MLC 104 IP Plus User's Manual 

for details.

The MLC 104 IP Plus controller has backlit buttons.  The button 

caps are removable so the button labels can be changed.  For 

instructions on how to change the buttons, refer to chapter 1 of 

the MCL 104 IP Plus User's Manual.

a

  Display On/Off buttons — After they have been configured 

(for instructions, see "Configuring the On and Off buttons" in 

chapter 3), press the On button to turn the display device on, 

and press the Off button to power it off.  Only one of these two 

buttons can be selected (active) at once.  You can assign other 

functions to these buttons via the Global Configurator software.

b

  Input selection buttons — By default, these buttons are a 

mutually exclusive group (only one of these buttons can be 

selected at a time).
Press an input selection button to select the desired audio and 

video input to the projector or an optional Extron switcher.  The 

button lights brighter and remains lit while an audio-video 

input is selected.

c

  Volume knob and LEDs — Rotate this knob to adjust the audio 

volume.  Global Configurator allows you to select whether this 

knob will control the projector’s audio levels or the optional 

MediaLink switcher’s audio levels.  

If the MLC is configured for use with a MediaLink Switcher 

or projectors, the MLC’s LEDs light to indicate volume ranges 

(with steadily lit LEDs) and minimum/maximum volume limits 

(with flashing LEDs).
If the MLC is configured for increment/decrement volume 

adjustment, the LEDs scroll up/down briefly.  

d

  Front panel Config port — This 2.5 mm mini stereo jack 

provides an RS-232 connection for configuration and control.  

An optional cable for this port is the 9-pin D Female to 2.5 mm 

TRS configuration cable, shown below, (Extron part #70-335-01).
