HDMI connectors
HDMI signals for 4K video run at a very high frequency and are especially prone to errors
caused by bad video connections, too many adapters, or excessive cable length. To avoid
the loss of an image or jitter, follow these guidelines:
•
Do not exceed 12 feet (3.6 meters) on the input of the encoder or the output of the
networked decoder.
•
Use only the cable designed for HDMI signals that is supplied by Extron.
•
Limit or avoid the use of adapters.
Use only cables specifically intended for HDMI or DVI signals. Use of non-HDMI or
•
non-DVI cables or modified cables can result in a missing video output.

Installing the LockIt Lacing Bracket
2.
Loosen the HDMI connection mounting screw from the panel enough to allow the
LockIt lacing bracket to be placed over it (
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 to which it
fastens is very thin and can easily be stripped.
•
Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel
elle est attachée est très fin et peut facilement être dénudé.
4.
Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket as shown (

While holding the connector securely against the lacing bracket, use pliers or similar
tools to tighten the tie wrap, then remove any excess length (
