Input Select buttons — The Input 1 Select through Input 4 Select buttons select the associated video and audio input. The selected video input is transmitted to the receiver. The selected audio input is output locally.

If a user-specified serial command is set for an Input Select button, the transmitter also sends that serial command to the receiver when the button is pressed. The receiver, in turn, issues the command to the projector. See chapter 4, “Serial Communications”, to specify the command to be sent.

The Input Select buttons are also used in conjunction with the Volume buttons ( 5 ) to adjust each input’s audio level. See “Volume adjustment” on page 3-5 for more details.

Blank button and LED — Press the Blank button to toggle video mute on and off. When the output is blanked, no video is transmitted to the receiver, which, in turn, outputs a blank image. The video mute function mutes the video signals only; the sync signal(s) are still active. The Blank LED lights to indicate that the video is blanked.

4Projector Power button and LED — Press the Projector Power button to transmit one of two user-specified serial commands to the receiver, which then issues the command to a device such as a projector. See chapter 4, “Serial Communications”, to specify the command(s) to be sent.

The Projector Power LED lights green when the power on command is the most recent command transmission and is unlit when the power off command is the most recent transmission.

If a projector power on (warm-up) delay or projector power off (cool-down) is programmed (see chapter 4, “Serial Communications”), the Projector Power LED blinks while that delay times out. All front panel operations are disabled during the delay.

Some projectors use the same command for power on and power off. If the same code is specified for on and off, the Projector Power LED blinks for each button push.
