Introduction
About this Manual
Application Diagrams
This manual contains information about the Extron IR 452
hand-held infrared remote control and instructions on using it to
control the MLC 52, the MLC 104, and the DVCM 50.
The terms "IR 452" and "remote control" are used
interchangeably in this manual.

About the IR 452
The Extron IR 452 is a hand-held remote control that is used
in conjunction with the Extron IRL 20 or the IR Link to control
the MLC 52 MediaLink Controller or the DVCM 50 DVD/VCR
Control Module, via infrared (IR) signals.
Communicating through the DVCM 50, the IR 452 can also
control the MLC 104 via the IRL 20 or the IR Link. The
IR 452 sends IR commands to the DVCM 50, which passes
the commands on to the MLC 104 in serial form as Simple
Instruction Set (SIS™ ) commands.

Setup and Operation
Enabling control of the MLC 104
Operational Overview
The MLC 104 can be controlled by the IR 452 via the
DVCM 50 in conjunction with the IR Link or IRL 20. To set up
the MLC 104 for control by the IR 452, do the following:
The IR 452 can control the MLC 52 or the DVCM 50. It can also
control the MLC 104 via the DVCM 50.
Button configuration on the control modules cannot
1.
Program the buttons on the MLC 104 and the DVCM 50
front panels with the desired commands. (Refer to the
product user's manuals for programming instructions.)
be performed from the IR 452. The commands must be
programmed on the MLC 52 or DVCM 50 using the
Windows-based configuration software or IR Learning.
2.
Connect the DVCM 50 rear panel host port to the MLC 104
rear panel host port. (Refer to the DVCM 50 User's Manual
for instructions and diagrams.)
Each button on the IR 452 front panel, when pressed, sends
an IR signal to the IR Link or IRL 20 signal repeater. The
IR Link or IRL 20 relays the signal to the MLC 52 or the
DVCM 50. The IR signal activates the equivalent button on
the MLC 52 or DVCM 50, causing the button to perform the
function that was programmed to it (e.g., turning the projector
on and off, selecting an input, or turning the projector volume
up and down).
3.
4.
Connect the IR Link to the DVCM 50 rear panel. (Refer to
the DVCM 50 User's Manual for instructions.)
Mount the MLC 104, the DVCM 50, and the IR Link or
IRL 20 on a wall or furniture as desired. (Refer to the
mounting instructions in the product user's manuals.)
If an MLC 104 is connected to the DVCM 50, the signal sent
from the IR 452 goes to the DVCM, which issues the appropriate
SIS™ command to the MLC 104. The SIS command activates the
appropriate button on the MLC 104, which communicates the
command to the display device via RS-232.
Changing button labels
You can use the Windows-based configuration software to
program the buttons on the MLC 52 and DVCM 50 to be used
for functions other than the pre-labeled ones. For example, you
might want to use the two MLC 52 buttons that are pre-labeled
Vol ꢀ and Vol ꢁ for additional input selections or for Auto
Image, instead of volume control.
Setting Up
Before you can use the IR 452 remote to control the MLC 52, the
DVCM 50, or the MLC 104, you must do the following:
To program the MLC 104 buttons, use the Global
Configurator 2 (GC2) software. Visit the Extron Web
software.
1
2
3
Program the buttons on the MLC 52 or the MLC 104
and/or the DVCM 50 with the commands you want them
to issue. Refer to the appropriate product user's manual
for programming procedures.
If you reprogram an MLC or DVCM button for a function
different from what its label indicates, you should also relabel
that button to reflect its new function. When you relabel
an MLC or DVCM button, you will also need to relabel its
equivalent IR 452 button to match it.
Make any needed changes to the button labels on the MLC
controller and/or the DVCM, if you have programmed
any buttons to have functions different from their
pre-installed labels.
With the IR 452, you receive a set of adhesive-backed labels,
which you can use to relabel IR 452 buttons as needed. The
figure on the next page shows the button labels that are
provided.
Wire and install the MLC 52 or the MLC 104; the
DVCM 50, if applicable; and the IR Link or the IRL 20,
following the directions in the appropriate product user's
manual.

5
Affix the provided button labels to the IR 452 overlay
as needed to match the buttons on the MLC and/or the
DVCM. (See Changing button labels, later in this chapter.)
Install the two provided AAA batteries in the IR 452. (See
Installing the batteries, later in this chapter.)

Setup and Operation, cont’d
In order for the IR 452 to be able to control the MLC 52 or the
DVCM 50, you must use the Windows®-based configuration
software or IR Learning to program the MLC 52 or DVCM
buttons with the functions for which their buttons are
labeled. Refer to the product user's manual for button labeling
information.
Buttons on the IR 452 Front Panel
The IRL 452 is provided with an overlay on which the buttons
are labeled as shown below. Its labeling scheme reflects that of
the MLC 52 and the DVCM 50.

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.
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.
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.
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.
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.
•
The projector or other display device responds to the
command it received from the IR 452 remote via the

Selecting DVD or VCR mode
The DVD and VCR buttons on the IR 452 are different from its
other buttons in that each contains a permanent mode switch
command. This command is sent to the DVCM 50, which
activates its equivalent button, or to the MLC 52, which activates
its programmed memory block, every time the button is
pressed. Regardless of any programming done to the DVD and
VCR buttons on the DVCM 50, pressing these IR 452 buttons
always causes the DVCM or MLC 52 to switch to the mode of
the button that was pressed.

Buttons and commands used with the MLC 104
The MLC 104 does not have buttons that control muting and
unmuting on the display device. However, you can program
Mute On and Mute Off commands onto the MLC 104 using
the Global Configurator (GC2) software. (Visit the Extron Web
site at www.extron.com for information on ordering the GC2
software.)
To control the MLC 104, you use the buttons in the Display and
Front Panel sections of IR 452, which are also used to control the
MLC 52.
The following table shows the SIS commands that are issued
from the DVCM 50 to the MLC 104 for each press of an IR 452
button, and the button that is activated on the MLC 104.
Depending on the feature set of your display device, you can
program the MLC 104 to mute/unmute the video, audio, or
both.
You must program the desired commands onto the
MLC 104's front panel buttons, using the Global
Configurator software, in order for the MLC to send the
correct command to the projector.
To use the IR 452 to control muting/unmuting, press the Mute
On or Mute Off button in the Display section. Pressing these
buttons causes the DVCM 50 to send an SIS command (1M for
Mute On button or 0M for Mute Off button) to the MLC 104,
causing it to mute or unmute the display device.

the button that is labeled On (in the Projector section). The MLC
104 responds by issuing the command to the projector to turn
on.
