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.
Setting the input auto switching mode via the front panel
1. Press and release input selection buttons 1 and 2 simultaneously
(see gure 3-5). The input auto switching LED (labeled “Auto SW”) indicates
the switching mode status (lit when enabled).
