BZBGEAR BG-EXHOC PRODUCT MANUAL
Introduction
The BG-EXHOC HDMI 2.0 Extender over Single Coax with bi-directional IR boosts your
HDMI transmission range up to 110m (363ft) in Ultra HD 4K2K format over a single coaxial
cable. BG-EXHOC is easy to install and works perfectly with Belden 1694A coaxial cables.
This device is also equipped with bi-directional IR pass-through. This feature allows users
to rely on the same coax cable to carry IR control data for devices like displays and media
players.
The BG-EXHOC is composed of two units: transmitter (BG-EXHOC[TX]) and receiver
(BG-EXHOC[RX]). The transmission range between the sending and receiving units can be
up to 110m (363ft) using Ultra HD (4K2K) with 2 channel audio.
Features
● HDMI 2.0 compliant
● 4K2K@60 4:4:4 8 bits*
● Extends the transmission range up to 110m (363ft) from the HDMI sources at
4K2K@60 4:4:4 8 bits
● HDCP input & output support
● Only needs a single coaxial cable
● Uncompressed HDMI over Coaxial cable transmission
● Audio sample rate supports 32KHz, 44.1KHz, 48KHz
● Auto signal equalization
● Supports full frequency IR signal from 20KHz to 60KHz
● Bi-directional IR path
● Wall mounting housing design for easy and robust installation
The range is dependent 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.
