Composite video outputs (Output 7 and Output 8) —
Connect composite video displays to these female BNC connectors.
NOTE: If the input tied to Output 7 or Output 8 is S-video,
the switcher encodes the input to composite video.
If the tied input is composite video, the switcher
passes it through to the output with no processing.
f
S-video outputs (Output 9 and Output 10) —
Connect S-video displays to these female BNC connectors.
NOTE: If the input tied to Output 9 or Output 10 is composite
video, the switcher decodes the input to S-video.
If the tied input is S-video, the switcher passes it
through to the output with no processing.

(Output 11 and Output 12) —
Connect S-video or composite video displays to
these female BNC connectors. Connect S-video
Y and C or composite video as shown at right.
NOTE: The switcher passes the tied input to these outputs
with no signal processing; an S-video input is output
as S-video, a composite video input is output as
composite video.

• The RS-232 Secondary port is active only if the front
panel Configuration port is not in use. If a front
panel configuration connection is made, the rear
panel RS-232 Secondary port becomes inactive and
the front panel Configuration port is active.
• See figure 3 for wire stripping information.
k
LAN port — If desired, connect a network WAN or LAN hub, a
control system, or computer to the Ethernet RJ-45 port.
• Network connection — Wire as a patch (straight) cable.
• Computer or control system connection — Wire the interface
cable as a crossover cable.
