Switch mode
Video switchers support autoswitch mode. In autoswitch mode, the switcher
automatically switches to the highest-numbered input with video sync signals
present. Input selection, by the front panel buttons or the RS-232/Remote port, is
blocked while in autoswitch mode. However, the front panel LEDs remain
functional and the Input 1 through Input 3 buttons can be used to view or change
the mode.
The switcher must be in normal (manual) mode for contact closure to work.
Audio breakaway is disabled in autoswitch mode; audio always follows video.
When you change from autoswitch to normal (manual) mode, the last input
selected in autoswitch mode remains selected until you manually select a
different input.
