unmute command. But what if someone uses the remote control of the projector to unmute
the video before the next MLC button press? The MLC issues a video unmute command
when the input 4 button is pressed, and the projector continues displaying video—there is
no change in mute status.
However, if, you also configure the MLC to check the AV mute status of the projector
each time the input 4 button is pressed, you can make the MLC act (or not) based on the
actual device status. That way, the MLC executes the correct action regardless of what
happened the last time the button was pressed on the MLC. This keeps the toggle button
synchronized with the status of the controlled device.
Prerequisite Setup Steps
1. Connect cables between the MLC, the input and output devices, and the PC, as
described in
Operation, Features, and Cabling starting on page 7.
2. Install and start the Global Configurator software.
3. Create or open a GC project.
4. Add an MLC to the project, if that has not already been done. For instructions, see the
Global Configurator Help file.
5. In Global Configurator, add device drivers and assign them to the Projector RS-232/IR
port or MLS port (see the
Global Configurator Help file for detailed procedures).
NOTE: For monitoring, the device must be connected to one of the bidirectional
ports on the MLC.
