Programming the MLC 52 for control by the IR 452 Remote

The optional IR 452 Remote Control can issue commands to a projector, DVD, VCR, or other device via the MLC 52, which can be programmed to pass on commands received from the IR 452 via the optional IR Link or IRL 20. After programming the MLC to recognize commands sent from the IR 452, you can control a projector or other display device by pressing the IR 452’s buttons while pointing it at the IR Link or IRL 20.

You can add up to four functions to each IR 452 button, including commands from different device drivers. This enables you to program one button to transmit a different command signal to up to four different devices, if desired. For example, you could program an IR 452 button in macro mode with four commands so that one press of the Power On button turns on your projector, DVD player, plasma display, and document camera all at once.

With the MLC 52 and IR Link or IRL 20 set up to receive command signals from the IR 452 with its multiple commands per button capability, you can eliminate the various remote controls for your DVD, VCR, projector, etc., and control all your devices using the IR 452.

The MLC 52 main screen contains a representation of the IR 452. You can store remote control button commands on the MLC by adding IR and/or RS-232 driver functions to these virtual buttons. The procedure for programming IR 452 button commands is the same as for the MLC 52 buttons. See “Assigning functions to buttons” on page 5-32 for this procedure.

In order to use the IR 452 remote with the MLC 52, you must install the IR Link or IRL 20 and connect it to the MLC. (See “Wiring for IR remote control,” in chapter 2, “Installation.”)

You cannot configure the MLC 52 from the IR 452 Remote Control.

Performing IR learning via software

The MLC 52 can “learn” commands from your display device’s remote control in order to control the projector, display, or devices such as VCRs or DVD players. Using IR learning, you can program command codes to a button’s four memory blocks. You can also use IR learning to program the IR 452 button functions on the MLC. The MLC cannot be mounted in the wall or furniture while you are doing this.

Follow these steps to initiate IR learning via the Windows-based configuration program:

1. Use an Extron Tweeker or other small screwdriver to set configuration DIP switch #1 on the MLC rear panel to the On (up) position.

2. Open the MLC 52 configuration software.

3. Click on the MLC or IR 452 button to which you want to program the command.

4.Click Learn IR to Button. The following prompt appears, showing the MLC or IR 452 button you selected and telling you to click OK when you are ready to start the IR learning process.
