Using the IR 452 with the MLC 52 and the IR Link
2 . Press the IR 452 button for the function you want to
perform. The following takes place:
• The remote control sends the pressed button’s
programmed command via infrared signal to the
IR Link or IRL 20 signal repeater.
• The signal repeater sends the command to the MLC 52
or the DVCM 50 through the IR In port on the back
panel, to which the signal repeater is connected.
• The MLC 52 or DVCM 50 recognizes the command it
receives via the IR In port, and responds as if its own
equivalent button were pressed, issuing the command
to the appropriate display device.
• The projector or other display device responds to the
command it received from the IR 452 remote via the
DVCM 50 or MLC 52.
Additional commands can be programmed to the DVD
and VCR selection buttons on the DVCM 50; however,
the mode switch commands cannot be removed from
those buttons.

9 MLC 104 volume control button — (DVCM 50) This rocker
button is used to raise and lower the volume of the display
device through the MLC 104. Pressing the up- or down-arrow
on this button sends an IR signal to the DVCM 50, which sends
an SIS command to the MLC 104, causing it to increase or
decrease the volume on the projector or other display device.
If you are using the DVCM 50 with the MLC 104,
the button should be labeled as Volume. See Volume
control on the MLC 104, later in this chapter, for more
information.
Using the IR 452
Once you have connected the MLC 52 or DVCM 50 to the
IR Link or IRL 20, programmed the buttons with the desired
commands, and connected/powered on all equipment, you can
use the IR 452 to perform all the functions on the MLC 52 and
DVCM 50 front panels and more.
