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.

NAuto switching is available only in single switcher mode. If separate switching mode is selected, auto switching is automatically disabled.

NWhenever 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 figure 3-5). The input auto switching LED (labeled “Auto SW”) indicates the switching mode status (lit when enabled).
