Special features
Tie (room relay) to Power — Enabling this feature for room relay 1 or room relay 2
will cause that relay to turn on/off when the Display Power is turned on or off.
Projector Comm — Set communications protocol (RS-232 vs. RS-422, baud rate,
parity, data bits) in this section.
Misc. Options — This section provides a way to send (or not send) various
commands, to mute audio, and to lock input selection when the Display
Power is turned on or off. Descriptions of each item are available in the
System 7SC Help file.
Limit initial power-up volume — Here you can specify an attenuation level for the
initial volume of the audio output. If the Limit initial power-up volume box
is not checked (enabled) or if the limit is set to 100%, the volume will not be
limited (attenuated).
Auto shutoff — If Auto shutoff 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).
