5.3 Connecting the REMOTE Connector
You can force the routing of one of the 2 inputs to the VGA output by remote
control. To do so, connect the appropriate REMOTE input terminal block
connector pins to a dry contact switch 1 . For example, as Figure 4 illustrates, to
route REMOTE IN 1 to the VGA output, connect PIN 3 to PIN 2. To route
REMOTE IN 2 to the VGA output, connect PIN 1 to PIN 2. Do not connect both
the REMOTE IN 1 and the REMOTE IN 2 to PIN 2 simultaneously.
Route input 1 to the output,
by attaching PIN 3 to PIN 2:
Route input 2 to the output,
by attaching PIN 1 to PIN 2:
Figure 4: Remote Terminal Block Connector
When both VGA IN 1 and VGA IN 2 are connected, the signal from VGA IN
1 routes to the output. However, you can force the routing of VGA IN 2 to the
output by attaching PIN 1 to PIN 2. If no input is present on VGA IN 1, you
can even force the routing of the output from VGA IN 1 (displaying a blank
screen) by attaching PIN 3 to PIN 2.
1 Note that the connection should be permanent, since the CSW-VGA211 will revert to an automatic switcher when the
connection is removed
