Buttons and commands used with the MLC 104
To control the MLC 104, you use the buttons in the Display and Front Panel sections of IR 452, which are also used to control the MLC 52.
The following table shows the SIS commands that are issued from the DVCM 50 to the MLC 104 for each press of an IR 452 button, and the button that is activated on the MLC 104.
You must program the desired commands onto the MLC 104's front panel buttons, using the Global Configurator software, in order for the MLC to send the correct command to the projector.

For example, the first row of the table above shows that when you press the Power On button in the Display section of the IR 452, the signal sent to the DVCM 50 is interpreted as the SIS command 1P. This command is sent to the MLC 104 to activate the button that is labeled On (in the Projector section). The MLC 104 responds by issuing the command to the projector to turn on.
Once you have programmed and labeled the buttons on the MLC 104, you should relabel the IR 452 buttons to indicate the commands they will initiate on the MLC 104.

Muting and unmuting
The MLC 104 does not have buttons that control muting and unmuting on the display device. However, you can program Mute On and Mute Off commands onto the MLC 104 using the Global Configurator (GC2) software. (Visit the Extron Web site at www.extron.com for information on ordering the GC2 software.)
Depending on the feature set of your display device, you can program the MLC 104 to mute/unmute the video, audio, or both.
To use the IR 452 to control muting/unmuting, press the Mute On or Mute Off button in the Display section. Pressing these buttons causes the DVCM 50 to send an SIS command (1M for Mute On button or 0M for Mute Off button) to the MLC 104, causing it to mute or unmute the display device.
