Connection Details
Connecting HDMI Connectors
Use an Extron LockIt lacing bracket to secure an HDMI cable to each device.
1. Plug the HDMI cables into the panel connection
(see
1
of the image to the right).
2. Loosen the side HDMI connection mounting screw from
the panel enough to allow the LockIt lacing bracket to
be placed over it (see
2
). 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 (see
3
).
ATTENTION: Do not overtighten the HDMI
connector mounting screw. The shield to which it is
fastened is very thin and can easily be stripped.
ATTENTION : 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 (see
4
).
5. While holding the connector securely against the lacing bracket, use pliers or a similar
tool to tighten the tie wrap, then remove any excess length.
