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.

Turn autoswitch mode on as follows:

1.	Press and hold the Mode (Input 1) button.
2.	Press and release the Auto (Input 3) button. The Auto Switch Active LED
	lights.
3.	Release the Mode button.
Turn autoswitch mode off as follows:
1.	Press and hold the Mode (Input 1) button.
2.	Press and release the Normal (Input 2) button. The Auto Switch Active LED
	goes off.
3.	Release the Mode button.
