Using the VP211K Automatic UXGA / Audio Switcher

5.2 Selecting the Default Master Source Signal
The DEFAULT INPUT switch is factory preset to IN 1 and the
VP-211K
will
detect the presence of the master source signal at the UXGA IN 1 connector.
If you connect active sources to both the UXGA IN 1 and the UXGA IN 2
connectors, the source at the UXGA IN 1 connector takes priority over the
source at the UXGA IN 2 connector and it is routed to the UXGA OUT and
the AUDIO OUT connectors (audio follows video).
You can change the default so that the
VP-211K
automatically detects an
active source signal from UXGA IN 2, by setting the DEFAULT INPUT
switch to IN 2. When active, the source at the UXGA IN 2 connector takes
priority over the source at the UXGA IN 1 connector and it is routed to the
UXGA OUT and the AUDIO OUT connectors (audio follows video).
If the
VP-211K
detects:
No signal
1
at the UXGA IN 1 input (when IN 1 is selected as the default),
the
VP-211K
routes the signal from the source at UXGA IN 2 to the
UXGA OUT and the AUDIO OUT connectors. Similarly, if the
VP-211K
detects no signal at the UXGA IN 2 input (when IN 2 is selected as the
default), the
VP-211K
routes the signal from the source at UXGA IN 1 to
the UXGA OUT and the AUDIO OUT connectors
A signal from the UXGA source at UXGA IN 1 input (when IN 1 is
selected as the default), while routing the signal from the UXGA source
at UXGA IN 2, the
VP-211K
will reroute the signal from the UXGA
source at UXGA IN 1 to the UXGA OUT and the AUDIO OUT
connectors. Similarly, if the
VP-211K
detects a signal from the UXGA
source at UXGA IN 2 input (when IN 2 is selected as the default), while
routing the signal from the UXGA source at UXGA IN 1, the
VP-211K
will reroute the signal from the UXGA source at UXGA IN 2 to the
UXGA OUT and the AUDIO OUT connectors
No signal at all (that is, when there is no active input from a source at
UXGA IN 1 or at UXGA IN 2), the
VP-211K
will still route UXGA IN 2
to the UXGA OUT, and continue to examine UXGA IN 1 input (when IN
1 is selected as the default), switching back to it when it detects a valid
signal. Similarly, if the
VP-211K
detects no signal at all (when IN 2 is
selected as the default), it will still route UXGA IN 1 to the UXGA OUT,
and continue to examine the UXGA IN 2 input, switching back to it when
it detects a valid signal
1 Perhaps no source is connected, or that source is connected but its power is OFF
