If you have issues, questions, or require assistance with the use of this device please
contact Liberty Wire and Cable with any of the following contact points:
The DigitaLinx™ HDMI™ Coax Transmission System is designed for years of
trouble free service, please reference the troubleshooting steps below if you are
having difficulties.
Recommendation:
Due to variations in the implementation of the HDMI standard by manufacturers
of source and display equipment, it is highly recommended that any system be
mocked up and tested with appropriate cable lengths prior to installation. There
are many compatibility issues with HDMI equipment that become more apparent
as cable extenders are added to the equation. This system goes to great lengths to
minimize those problems. However, after wire is installed, the walls finished and
the display is hung, it’s a little late to find that the source isn’t compatible with the
switching equipment, transmission equipment and the display.
− All cables must be properly connected for any signal to be transmitted.
− If no image is displayed, confirm that all coax cables are properly connected, red to red, green to green etc.
− If there is still no image, confirm that all cable are continuous and not shorted between the center
conductor and the shield.
− Some VGA cables use a twisted pair for the H and V signals. This device requires a coax cable for channels 1-4.
− Cables should be similar in length and of the same part number and manufacturer. CATV/MATV style cables
with Copper Clad Steel conductors and Aluminum braid shields are not recommended.
− Signals on these cables are bi-directional so the coax signals will not function if connected to intermediate
electronics (such as an RGBHV switcher).
− If the system does not function try lower resolutions from the source
− All LEDs will be on with a properly connected system. All LEDs being on does not indicate a properly
connected system.
− The Yellow power channel can be used to determine if the cables are properly constructed. Disconnect all
Coax cables. One at a time connect each cable to the yellow BNC connector with the power supply connected.
If the Power LED on the unit not connected to the power supply illuminates, the cable is not open, nor does it
have a short. Return it to its proper connectors beginning at end that has the power supply.
