5.2 Selecting the Default VGA Master Source Signal
Both DEFAULT SELECT switches are factory preset to IN 1 and the
CSW-VGA211
will detect the presence of the master source signal at the
VGA IN 1 connector. If you connect active sources to both the VGA IN 1 and
the VGA IN 2 connectors, the source at the VGA IN 1 connector takes
priority over the source at the VGA IN 2 connector and it is routed it to the
VGA OUT and the AUDIO OUT connectors (audio follows the video).
You can change the default so that the
CSW-VGA211
automatically detects
an active source signal from VGA IN 2, by setting the pair of DEFAULT
SELECT switches
1
to IN 2. When active, the source at the VGA IN 2
connector takes priority over the source at the VGA IN 1 connector and it is
routed to the VGA OUT and the AUDIO OUT connectors (audio follows the
video).
If the
CSW-VGA211
detects:
No signal
2
at the VGA IN 1 input (when IN 1 is selected as the
default), the
CSW-VGA211
routes the signal from the source at VGA IN
2 to the VGA OUT and the AUDIO OUT connectors. Similarly, if the
CSW-VGA211
detects no signal at the VGA IN 2 input (when IN 2 is
selected as the default), the
CSW-VGA211
routes the signal from the
source at VGA IN 1 to the VGA OUT and the AUDIO OUT connectors
A signal from the VGA source at VGA IN 1 input (when IN 1 is
selected as the default), while routing the signal from the VGA source at
VGA IN 2, the
CSW-VGA211
will reroute the signal from the VGA
source at VGA IN 1 to the VGA OUT and the AUDIO OUT connectors.
Similarly, if the
CSW-VGA211
detects a signal from the VGA source at
VGA IN 2 input (when IN 2 is selected as the default), while routing the
signal from the VGA source at VGA IN 1, the
CSW-VGA211
will
reroute the signal from the VGA source at VGA IN 2 to the VGA OUT
and the AUDIO OUT connectors
No signal at all (that is, when there is no active input from a source
at VGA IN 1 or at VGA IN 2), the
CSW-VGA211
will still route VGA
IN 2 to the VGA OUT, and continue to examine VGA IN 1 input (when
IN 1 is selected as the default), switching back to it when it detects a
valid signal. Similarly, if the
CSW-VGA211
detects no signal at all
(when IN 2 is selected as the default), it will still route VGA IN 1 to the
VGA OUT, and continue to examine VGA IN 2 input, switching back to
it when it detects a valid signal
1 Both DEFAULT SELECT switches MUST be set to the identical IN #
2 Perhaps no source is connected, or that source is connected but its power is OFF
