Extron electronic MLC 52 manual Removing commands from a button, Setting up button macros

7. Press the buttons that you configured to verify that the commands you entered have been learned. If you have an IR Emitter connected on the IR output, it should blink. (See “Wiring for IR control” in chapter 2, “Installation.”)

Removing commands from a button

If you want to delete a command that has been programmed onto a button, you must remove all the commands programmed to that button, as follows:

1.	While the MLC 52 is powered on, set configuration switch #1 to On (up).
2.	Press the button for which you want to delete commands, then within
	2 seconds press the same button again. The IR learning LEDs turn off.
3.	Verify that the button’s commands were erased by pressing the same button
	again. If the commands have been erased, only LED #1 (the bottom LED)
	blinks; the other LEDs remain off.
4.	When finished removing commands, set switch #1 to Off (down).

Setting up button macros

Buttons function in either toggle mode or macro mode. By default, all the buttons (except the On and Off Display buttons) are in toggle mode. This means that each press of the button issues one command — the next in sequence of the four commands programmed to the button (each button can store up to four commands).

In macro mode, a single press of a button issues all the commands (up to four) that have been programmed on that button, in the order they were programmed, at

1.5-second intervals. An example of a button macro application would be turning on multiple projectors/displays by pressing one button, one time.

To program a macro for a button,

1.	Ensure that power is applied to the MLC 52.
2.	Set configuration switch #1 on the rear panel to On (up). All front panel
	buttons light dimly.
3.	Program the buttons with the desired commands. See “Configuring using IR
	data transfer” or “Configuring using IR learning,” earlier in this chapter, for
	programming procedures.
		You must program the commands onto the button prior to setting it for macro.
4.	To put the button in macro mode, press and hold it for 3 seconds. The orange
	LED on the back panel, labeled “E,” flashes rapidly five times, then turns off,
	indicating that the button is now configured for macro mode. Release the
	button. The next time that the button is pressed while configuration switch #1
	is in on position, the orange “E” LED lights, indicating that the button is in
	macro mode.
	To take a button out of macro mode, press and hold the button for 3 seconds.
	The orange “E” LED turns off.
5.	Set configuration switch #1 to Off. Verify that the commands have been
	properly learned by pressing the button you programmed. The commands
	should be issued in succession at 1.5-second intervals.

A button is able to learn commands while in macro mode if any of its four command memory blocks are open (not yet programmed with a command).
