Inputs 1, 2 and 3 can be set in priority according to your needs. The VP-311DVI
switches to the secondary input upon loss of the primary input signal, and back to
the primary input when a signal is detected. The following table describes the
priority setup:

Priority Switching Applications
In the following example, DIP-switches 1, 2, and 3 are set to OFF, OFF and OFF
respectively, meaning that the highest priority input is IN 1; IN 2 is the secondary
input; and IN 3 the third. DIP-switch 4 is set ON, enabling AUTO mode operation.
If all the inputs are connected, you can, for example, press the INPUT SELECTOR
2 button to switch IN 2 to OUT. The plasma display shows the IN 2 signal.
If the DVI signal on IN 2 is cut off, the switcher automatically switches IN 1 to the output,
and if that fails too, IN 3 is automatically switched to the output. If, in the meantime, the
IN 2 signal is restored, IN 2 takes priority once again.

Connecting the Contact Closure Remote Control Pins
The contact closure remote control pins operate in a similar way to the input
buttons.
For example, you may override (equivalent to pressing a different input button) the
presently routed input by using the remote control contact closure. To do so,
connect the appropriate input number pin on the REMOTE terminal block
connector to the G (Ground) pin, as
illustrates.
When in the manual mode (DIP-switch 4 set to OFF), you can switch an input to the output
using the front panel INPUT SELECT buttons.
Note that unless the connection is permanent, the VP-311DVI reverts to an automatic switcher
when the connection is removed.
