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.
