3. Connect an HDMI cable from the HDMI Video Source Device to the Video

Input Port on the back of the HDMI Transmitter.

Note: If you are using a locking HDMI cable, use a Phillips Head Screwdriver

to remove the screw above the HDMI In 1 Port. Insert and tighten the Locking
Screw in the Locking Screw hole above the corresponding HDMI Port. Con­nect an HDMI cable to the HDMI In 1 Port on the back of the HDMI Transmit­ter. Insert a Locking Screw in the Lock Bolt hole above the HDMI Port on the
HDMI Transmitter. Using the Phillips Head Screwdriver, tighten the Locking
Screw. Be careful not to over-tighten.

Notes: Properly grounding the HDMI Transmitter and HDMI Receiver can

prevent damage and improve audio/video signal quality.

The cabling should not go through any networking equipment (e.g. router,
switch, etc.).

For best results use a CAT6 STP Cable.

Display Device into the HDMI Out 1 Port. Refer to Steps 3 - 5, if you are using
a locking HDMI cable.

Notes: Follow steps 1 - 9 to connect a second HDMI Video Source and HDMI

Display Device. Make sure that you use the HDMI In 2 and HDMI Out 2 Ports
instead of using the HDMI In 1 and HDMI Out 1 Ports as outlined in the
Installation steps.

Video source and destination have a one to one relationship, video cannot
be switched or split.

9. Connect the Universal Power Adapter to the DC 12V Power Port on both the

HDMI Transmitter and HDMI Receiver and the other end to an AC Electrical
Outlet.
