INTRODUCTION
The EX-54RZ2 HDMI 2.0 Extender over Single Coax with Bi-directional IR boosts up your HDMI
transmission range up to 110m (363ft) in Ultra HD 4K2K format through single coaxial cable. EX-54RZ2
is easy to install and works perfectly with Belden 1694A coaxial cables. Other coaxial cables can also
work with EX-54RZ2 and the transmission distance depends upon the quality and bandwidth of coaxial
cables. In addition, EX-54RZ2 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 EX-54RZ2 makes IR control possible through only single coax cable along with
high quality HDMI A/V signals.
The EX-54RZ2 includes two units: transmitting (EX-54RZ2[TX]) and receiving (EX-54RZ2[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 110m (363ft) under
Ultra HD (4K2K) with 2 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.
