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.

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.

(You can program the buttons to perform functions other than those for which they are labeled. If you do this, you will need to relabel the buttons on the MLC and/or the DVCM, and on the IR 452, to reflect the programming.)

If you program the MLC 52 or DVCM buttons as labeled, pressing the equivalent IR 452 buttons issues the commands as described below.

1 Display power buttons — Pressing these two buttons sends IR

signals to the MLC 52 or MLC 104 (via the DVCM 50) to activate

the buttons labeled On and Off.

When the MLC On and Off buttons are programmed as labeled,

the IR 452 Power On and Power Off buttons turn the projector

or other display device on and off.

2 Mute On and Mute Off buttons — These buttons are not

direct equivalents of any buttons on the MLC 52 or MLC 104.

However, you can use your MLC's configuration software to

program the MLC to mute and unmute the video and/or audio

on the display device when these IR 452 Mute buttons are

pressed.

The following configuration software programs are available:

MLC 52 and DVCM 50: MLC 52 Control Program (Windows-

based configuration software). Use the Advanced Projector

Config. screen to program these buttons.

MLC 104: Global Configurator 2 (GC2)

3 TV/VCR button — Pressing this button sends an IR signal to

either of the following:

• The MLC 52 to activate the memory block that has been

programmed with the TV/VCR switch command

• The DVCM 50 to activate the button labeled TV/VCR

The MLC 52 or DVCM 50 must be in VCR mode. If they are in DVD mode, this button has no effect. See Selecting DVD or VCR mode, later in this chapter.
