This DigitaLinx™ HDMI™ Coax Transmission System is an externally powered digital HDMI
and DVI transmission system to send HDMI and DVI signals over four coaxial cables. The
fth coaxial cable is for 12 VAC power distribution. The device is compliant with DVI 1.0 and
supports HDMI 1.3 high speed signals. The device is fully compliant with HDCP protocol,
CEC (control) and DDC (Monitor Identication). This device uses Gennum’s ActiveConnect™
Technology to transmit HDMI and DVI over long distances at very high data rates.
In addition to new installations requiring long transmission distances at high resolutions,
this HDMI™ Coax Transmission System is ideal for installations where a pre-wire or past
installation has been completed with RGB cable or where space constraints limit installing
HDMI® or DVI cables. The RGB cable solution is also excellent for retrot applications.
Current Analog RGBHV installations can be quickly and easily converted to Digital HDMI™.
The compact design allows the devices to be unobtrusive in the nal installation. It is
recommended to test an application using the customer equipment as the signal from the
source device varies between manufacturers.
The system can easily accommodate DVI only inputs and outputs by using Liberty’s high
quality HDMI to DVI interconnects. The DVI connector is routed to the sources and display
unit while the HDMI connector plugs into the DigitaLinx™ HDMI™ Coax Transmission System.
The digital audio signal is not transmitted when using DVI connectors.
The actual transmission distance can vary depending on many factors. Maximum distances
are a function of resolution, color depth, refresh rate, cable quality and termination quality.
The quality of the RGB cable is a prime factor in limiting distances. The use of Serial
Digital Coaxial cable will extend distances. SDI Coaxial Construction is a 100% bonded
foil shield and a 95% coverage Tinned Copper braid shield with an SRL value greater then
-20dB to 750 MHz. Use of a braid shield only coaxial cable like a closed circuit TV coax is
not recommended due to the transmission of higher frequencies however it will work to
reduced distances.

This is a practical application chart with actual observed distances and performance in a real
application. Longer distances can be achieved at lower resolutions. Higher resolutions and
color depths will result in shorter distances. Some sources do not adhere to HDMI standards
and may not be transmitted the full expected distance.

High Quality Picture –
No Loss of Resolution or introduced Digital Artifacts
Our HDMI™ Coax Transmission System is manufactured to deliver the highest
quality picture by preserving the native resolution from the video sources and
eliminating any digital artifacts (pixel loss or “sparklies”). Due to the nature of
digital signals any non-active connector junctions will detrimentally aect the
signal, this device provides active junctions to equalize and amplify the signal
(boosting) and ensures the best signal quality to the display.
No Digital to Analog or Analog to Digital Conversion
This device does not convert the digital HDMI signal to an analog signal. Rather
it takes advantage of the high bandwidth capabilities of a coax cable to transmit
the digital HDMI signal hundreds of feet. HDCP, DDC and CEC signals are also
supported to the full transmission distance of the HDMI signal.
Signal Amplication
Each HDMI™ Coax Transmission System has a safety certied 12 VAC external
power supply to ensure adequate power is available to perform the signal boost
to the correct specication. This is necessary because the introduction of a
HDMI™ Coax Transmission System usually indicates that longer cable lengths are
in use. This device amplies and equalizes the signal from a longer length cable
to the original native shape and signal power. All Liberty Wire & Cable HDMI
interconnects are tested to ensure 1080p resolution.
Compact Design
The HDMI™ Coax Transmission System device is manufactured in a small
convenient form factor which allows the devices to be situated in an unobtrusive
installation. The Five BNC receptacles are oriented 180° from the HDMI connector
to facilitate a straight cable lay.
Wide Range of Power Input
The HDMI™ Coax Transmission System device is manufactured to support the
custom installation market and the device can accommodate a wide range of
input power sources. It can accept DC power from 10-32 volts and AC power from
10-28 volts. Each unit is packaged with a Phoenix style connector for assembly
onto the power supply wires.

Installation
Installation
The recommended method for connection of devices to the HDMI™ Coax
Transmission System is listed in the following steps. Please ensure this order is
followed to enjoy the full function of the device.
1.) Ensure the digital video/audio source and display is turned o.
2.) Connect the digital video/audio source to the input port of the DigitaLinx™
HDMI™ Coax Transmission System.
3.) Connect the digital display to the output port of the DigitaLinx™ HDMI™
Coax Transmission System.
4.) Power up the DigitaLinx™ HDMI™ Coax Transmission System. Power LEDs
on both the transmitter and receiver should be illuminated.
5.) Power up the digital display.
6.) Power up the digital video/audio sources
7.) HDCP handshaking operation can take up to 20 seconds.
8.) Check the LED power indicator and status indicators on the DigitaLinx™
HDMI™ Coax Transmission System. The signal indicators should be lit when
the devices are correctly attached. It does not indicate successful data
transmission between the transmitter and receiver. See troubleshooting on
Page 12 if the LED’s are not lit.

Alternative Power Strategies
Note: The unit can function without the fth coaxial cable if power is supplied
to both the TX and RX unit by separate DC power units. Extra Power units are
sold separately under part number DL-HDCX-PS. In addition the power supply
can be connected at either the TX or RX end of the system. If there are only 4 coax
cables available a twisted pair cable can be connected between the green phoenix
power supply connectors to supply power to the TX or RX not directly connected
to the power supply. Make sure that the twisted pair and power supply are
adequate to provide at least the minimum power to the distant device. e.g. A 10
volt power supply and a 24 AWG twisted pair will not be adequate at 200 feet due
to cable losses.
If AC power is used it must be ungrounded (one side of power can not be
connected to the coax shield).

If you have issues, questions, or require assistance with the use of this device please

The DigitaLinx™ HDMI™ Coax Transmission System is designed for years of
trouble free service, please reference the troubleshooting steps below if you are
having diculties.
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 nished and
the display is hung, it’s a little late to nd 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, conrm that all coax cables are properly connected, red to red, green to green etc.
− If there is still no image, conrm 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 andV 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.
− TheYellow 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.
