• Connect the receiver’s HDMI output to the display using a short, high quality
cable no longer than nine feet for 24 bit and 36 bit signals (see pages 4 and 5).
• Plug in the provided AC adapter(s): first to the HCX-11 transmitter (and receiver,
if external power is used), and then to active AC power outlet(s).
• It is recommended to apply power in this sequence: HCX-11 Transmitter
and receiver, then the HDMI source, then the video display. The HDMI LINK
indicator confirms video is being transmitted.

• Make sure the display can accept the resolution and refresh rate output by
the source. Adjust the source output resolution and refresh rate if necessary.
Always test the source and display via a direct HDMI connection before
installation.
• Check the HCX-11 power connection(s) and verify the AC power outlet(s).
• If you encounter problems using the five-cable internal power configuration,
try disconnecting the INTERNAL POWER coax cable at both ends, and use a
power supply at the receiver end. Remember to set POWER MODE switch to
External (EXT). If this solves the problem, either the coax cable is at fault, or the
distance is too long for internal power.
• Use a cable tester to verify continuity in all coaxial cables, and good BNC
terminations.
• Check the HDMI cable connection points to see if the connectors have become
loose. Use good strain relief methods to insure a reliable connection.
• Inspect the HDMI cables for damage, and/or substitute a known good cable.
• Make certain you are using the highest quality, and the shortest length HDMI
cables possible. See page 5 for HDMI cable length guidelines.
• Make certain the coaxial cables are connected to the correct jacks at both ends.
• Check the cable lengths to be sure they are within the limits found on page 4.
• Do not use inferior quality cables; good quality RG-6 or RG-59 type coaxial
cables must be used. Using RG-59 may not allow maximum cable lengths.
