Extron electronic MLC 52 manual Selecting Inputs, Powering off

Powering off

To turn the projector/display off, press the Off button. The button blinks for 4 seconds, then remains steadily lit.

(A 2-second hold feature, requiring you to press and hold the Off button for 2 seconds in order to turn off the display device, helps prevent accidental powering off of the projector or display. This feature can be disabled and enabled through the configuration software. See “Entering display device power settings,” in chapter 5, “Serial Communication,” for further information.)

Selecting Inputs

The four buttons below the Display On and Off buttons on the MLC 52 front panel can configured to select inputs on the display device. The PC and Video buttons have been preconfigured to select inputs — the desktop or laptop computer (PC); the VCR or DVD (Video).

Using IR learning, IR data transfer, or the Windows-based configuration software, you can reconfigure these buttons and/or add commands to them to select other inputs if desired. The two volume (Vol) buttons on the standard MLC can be configured to select inputs as well, if you do not need them to control projector or display volume. Up to four commands can be programmed on any button. See “Using the MLC 52 Configuration Program,” in chapter 5, “Serial Communication,” for information on configuring MLC buttons.

Input selection buttons on the MLC 52 front panel

To select an input, press and release the appropriate input selection button. The command that was programmed in the button’s first memory block is executed.

•All buttons are lit at 25% intensity while the MLC receives power. A selected (active) input button lights more brightly than the other buttons.

•If there is more than one input selection command programmed in the button’s memory blocks, you can execute the commands in memory blocks 2, 3, and 4 by pressing the button a second, third, and fourth time.

For example, if you have programmed memory block 1 on the Video button for a VCR, and memory block 2 for a DVD player, you would press and release the Video button once to select the input to which the VCR is connected on the display, then a second time to select the input to which the DVD player is connected on the display. (Pressing it a third time reselects the VCR, etc.)
