Extron electronic MLC 52 manual Configuring using IR learning

After approximately 17% of the data has been transferred, the On button lights and remains lit to maximum brightness. After another 17% has been transferred, the Off button lights to maximum brightness. The buttons continue to light brightly in clockwise order after each increment of 17% of the data has been transferred. When a button becomes permanently lit, the remaining buttons continue to blink in clockwise rotation, until the transfer process is complete and all buttons are remain steadily lit.

The following table shows how each percentage of transferred data is indicated by button lighting:

Percent Complete	MLC 52	MLC 52 VC Models
	Buttons Lit	Buttons Lit
Less than 17%	On	On
18% to 36%	Off	Off
37% to 54%	PC	PC
55% to 72	Video	(blank)
73% to 90%	Vol <	DVD
90% to 100%	Vol >	VCR

When the transfer is complete, all buttons on each unit remain brightly lit until a button is pressed on the unit.

If the transmission is interrupted (for example, the two units become separated so that the IR LEDs are no longer in direct line of sight of each other), and the conditions necessary for transfer are then restored, the two units restart the transfer process.

4. When the data transfer is complete, do either of the following:

•If you are finished performing data transfers, return configuration switch #2 on the receiving MLC to the off (down) position. Press any button on both units to return them to the state they were in before the transfer. All buttons dim except for those that were bright previously. Reinitialize the receiving unit by pressing any of its front panel buttons.

•If you want to repeat the transfer process to configure another MLC 52, repeat steps 2 and 3 for the unit that is to be configured. Press any button on the donor unit. The transfer process restarts.

Configuring using IR learning

You can also configure the MLC 52 by using IR learning, which does not require configuration software. By this method, you can program the functions on your display device’s remote control onto the buttons on the MLC front panel. This procedure must be performed before the MLC is mounted on a wall or furniture, so that the IR Transmit/Receive LEDs are accessible.

To program the MLC via IR learning,

1.	Apply power to the MLC 52.
2.	On the rear panel, set configuration switch #1 to On (up). All
	front panel buttons should be dimly lit.
