INTRODUCTION
The CV-54R HDMI Extender over Single Coax with Bi-directional IR boosts up your HDMI
transmission range up to 120m (394ft) in HDTV 1080p format through single coaxial cable. CV-54R is
easy to install and works perfectly with Belden 1694A coaxial cables. Other coaxial cables can also work
with CV-54R and the transmission distance depends upon the quality and bandwidth of coaxial cables. In
addition, CV-54R is also equipped with bi-directional IR pass-through path. This bonus feature allows
users to rely on the same coax cable to have IR control on IR equipped devices, such as TV and BD
players, and CV-54R makes IR control possible through only single coax cable along with high quality
HDMI A/V signals.
The CV-54R includes two units: transmitting (CV-54R[TX]) and receiving (CV-54R[RX]) units. The
transmitting unit is used to capture the HDMI and HDCP input signals and carry the signals through only
coaxial cable. The receiving unit is responsible for auto equalizing the transmitted HDMI multimedia data.
The transmission range between the sending and receiving units can be up to 120m (394ft) under Full HD
(1080p) with 7.1 channel audio.

The length depends on the characteristics and quality of the coax cables. Higher resolutions
and longer transmission distances require low skew cables for best performance. Solid and
shielded coax cable such as Belden 1694A with metal 75ΩBNC connectors is recommended.

NOTICE
Since CV-54R is sensitive to the HDMI source’s input jitters, the input HDMI signals with larger jitters
will shorten the transmission distance hugely, especially for full HD 1080p@60!
1. The lab testing result shows that Belden 1694A coaxial cables can transmit HDMI signals up to 120m
(394ft).
2. If your HDMI display has multiple HDMI inputs, it is found that the first HDMI input [HDMI input #1]
generally can produce better transmission performance among all HDMI inputs.
3. Please noticed that audio must be 48KHz and 480p is not supported.
