RS-232 and IR connectors

Figure 5 shows how to wire the RS-232 and IR connector.

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

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.

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 figure 7).

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.

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.

ATTENTION: Do not overtighten the HDMI connector mounting screw. The shield it fastens to is very thin and can easily be stripped.
