Extron electronic MEDIALINK MLC 52 - Manual (Page 51)

4-7 MLC 52 Series MediaLink Controllers • Special Applications
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.)
Yes: Press Again No: Please Wait
Turn Power OFF?
