Display Power button
To send a power-on command, press and hold the Display Power button for two seconds. At the end of two seconds, the button will flash twice, then glow steadily while the display device is on.
If AC power is removed from the switcher while Display Power is on, the switcher will send an RS-232 power-off command to the display device before shutting down. The System 7 cannot send a power-off command via IR after power has been disconnected.
To turn the display device off, again press and hold the Display Power button for two seconds. The System 7 will send the power-off command, and the Display Power button will flash twice, then turn off (go dark). Many projectors require a power-off delay. The System 7 has a brief power-off delay, during which the power-off command is resent to the display device.
To shut down the projector if the switcher hasn’t been used for a set amount of time, a built-in inactivity shutdown timer can be set by using the included control software. If the inactivity timer is enabled, the switcher monitors the time elapsed since the last input selection (or other function) and sends a display power off command (or that command and any other commands associated with the Display Power button) after a set period of inactivity. That period can be selected in fifteen-minute increments to be as long as 480 minutes (8 hours). See chapter four, “Serial Communication”, for details. To turn the projector on again after it has shut down, you must press the Display Power button, click the Display Power button within the control software, or send the switcher the 1P SIS command via RS-232.
The Display Power button can also have the functions of one of the Room buttons assigned to it. The associated room function (relay activation + associated commands) can be executed immediately after the Display Power IR and/or RS-232 commands are sent. The Room button will light when the room function is executed.
Display Mute button
Once it has been programmed for use with the projector, press and release this button to send a mute on/off command to the display device. The button will not flash before sending the command.
Display Mute is only active when Display Power is on.
Mode button
Press this button to execute any IR or RS-232 command that has been programmed into its memory. For example, it can be used to switch the mode of the projector between computer video (RGB), S-video, and composite video, replicating the 1-button (step) mode function provided on some projectors’ remote controls.
