3-13 MLC 52 Series MediaLink Controllers • Operation
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.)
