Figure 5. RS-232 and IR Connector Wiring
NOTES:
• The length of exposed wires is critical. The ideal length is
3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the
exposed wires may touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inch,
wires can be easily pulled out even if tightly fastened by the
captive screws.
• Do not tin the power supply leads before installing them in the
connector. Tinned wires are not as secure in the connector and
could be pulled out.
HDMI connectors
Use a LockIt Lacing Bracket to securely fasten each HDMI cable to the
switcher as follows.
1. Plug the HDMI cable into

the panel connection.
2. Loosen the HDMI
connection mounting screw
from the panel enough
to allow the LockIt lacing
bracket to be placed over it.
The screw does not have to
be removed.
3. Place the LockIt lacing
bracket on the screw
and against the HDMI
connector, then tighten
the screw to secure the
bracket.
ATTENTION: Do not overtighten the HDMI connector mounting
screw. The shield it fastens to is very thin and can easily be
stripped.
4. Loosely place the included tie wrap around the HDMI connector and
the LockIt lacing bracket as shown.
5. While holding the connector securely against the lacing bracket, use
pliers or similar tool to tighten the tie wrap, then remove any excess
length.

ATTENTION: For unbalanced audio output, connect the sleeves to
the ground contact. DO NOT connect the sleeves to the negative (-)
contacts.
NOTE: The length of exposed wires is critical (see the RS-232
connector NOTES on page 14 for more information).
Analog video connectors
The universal analog video boards can accept RGB video and (with
adapters) component video, S-video, and composite video (see gure 7).

Figure 7. Analog Video Connector Wiring
For component video, use the R (R-Y) and R return pins (pins 1 and 6),
G (Y) and G return pins (pins 2 and 7), and B (B-Y) and B return pins
(pins 3 and 8).
For S-video, use the R, R return (C-chroma), G, and G return (Y-luma)
pins.
For composite video, use the G pin and the associated return pin.
Input only sync signals, no video signals, on the sync pins, 13 and 14.
