Setup and Operation

Operational Overview

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 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.

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).

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.

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:

1Program 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.

2Make 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.

3Wire 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.

4Affix 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.)

5Install the two provided AAA batteries in the IR 452. (See Installing the batteries, later in this chapter.)

Enabling control of the MLC 104

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:

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.)
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.)
3.	Connect the IR Link to the DVCM 50 rear panel. (Refer to
	the DVCM 50 User's Manual for instructions.)
4.	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.)

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.

To program the MLC 104 buttons, use the Global Configurator 2 (GC2) software. Visit the Extron Web site at www.extron.com for information on ordering this software.

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.

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.
