9MLC 104 volume control button — (DVCM 50) This rocker button is used to raise and lower the volume of the display device through the MLC 104. Pressing the up- or down-arrow on this button sends an IR signal to the DVCM 50, which sends an SIS command to the MLC 104, causing it to increase or decrease the volume on the projector or other display device.

If you are using the DVCM 50 with the MLC 104, the button should be labeled as Volume. See Volume control on the MLC 104, later in this chapter, for more information.

2. Press the IR 452 button for the function you want to perform. The following takes place:

•The remote control sends the pressed button’s programmed command via infrared signal to the IR Link or IRL 20 signal repeater.

•The signal repeater sends the command to the MLC 52 or the DVCM 50 through the IR In port on the back panel, to which the signal repeater is connected.

•The MLC 52 or DVCM 50 recognizes the command it receives via the IR In port, and responds as if its own equivalent button were pressed, issuing the command to the appropriate display device.

•The projector or other display device responds to the command it received from the IR 452 remote via the DVCM 50 or MLC 52.
