Extron electronic MLC 52 instruction

Programming buttons for multiple inputs on an RS-232 controlled system

If the MLC 52 RS is to control the projector via RS-232, the projector’s remote control does not need to be involved. Program the MLC buttons directly via the front panel configuration port using Windows-based configuration software (see chapter 5, “Serial Communication,” for information on using these control methods).

1.	Program commands 1 and 2 on the PC and Video buttons with the projector’s
	RS-232 command for discrete input selection.
2.	The MLC now has two commands each on the PC and Video buttons. Press
	these buttons repeatedly to switch between the two input selection commands
	that you entered on each button.

Application 2: Projector Requiring a Power Off Confirmation

Some projectors controlled via IR require the Power Off button on the hand-held remote control to be pressed twice to turn off the projector. These projectors usually present a prompt (similar to the one shown below) on the image, instructing you to press the Power Off button again to confirm your intent to power off the projector. (If the projector is controlled via RS-232, this prompt is usually not displayed.)

Turn Power OFF?

Yes: Press Again No: Please Wait
