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
fifth 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 Identification). 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 retrofit 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 final 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.
