Auto Switching

The PVS 204SA has an auto switching feature in single switcher mode only, that

detects which input has an active sync signal and automatically switches to that

signal.
In single switcher mode, the auto input switching follows the highest numbered

active input, regardless of the signal format (RGB or composite video). For

example, if input #2 (RGB) is currently active, and then #4 (composite video)

becomes active, the input automatically switches to #4, regardless of format. In this

example, the output signal changes from RGB to composite video.
The PVS 204SA auto switching can be switched on or off from the front panel

or via RS-232.

N

Auto switching is available only in single switcher mode. If separate switching

mode is selected, auto switching is automatically disabled.

N

Whenever an input changes, the switcher sends an unsolicited response via

RS-232 to the controller, alerting the controller of a possible need to change the
projector input command.
