2. Loosen the HDMI connection mounting screw from the panel enough to allow the
LockIt lacing bracket to be placed over it (
b ). 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 (
c ).
ATTENTION: Do not overtighten the HDMI connector mounting screw. The shield
to which it fastens is very thin and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket (
d ).
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 (
e ).

NOTE: The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
• Longer bare wires can short together.
• Shorter wires are not as secure in the connectors and could be pulled out.
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• no flow control
