INTRODUCTION

The

CV-57C HDMI Extender over Dual Cat.X with IR

boosts up your HDMI transmission distance
up to 60m (200ft) in HDTV 720p / 1080i format. With two low cost Cat-5/5e/6 cables, users can readily
extend HDTV sources from DVD players, Blu-ray Disc player, PS3, PC, and any other kinds of sources
compliant with TMDS to distant display monitors including HDMI enabled TV sets, LCD PC monitors, or
projectors. This cost effective flexibility makes HDCP compliant DVD players or PS3 transmit high quality
video and audio with a greater distance at the minimal cost, when integrating several components apart.
In addition, with the embedded infrared (IR) receiving and emitting units to facilitate the control path,
users can enjoy high quality audio/video and control the HDMI sources from the remote site instantly.

The CV-57C includes two units: CV-57C-TX as the transmitting unit and CV-57C-RX as the receiving
unit. The transmitting unit is used to transfer the HDMI or DVI and IR signals input and carry the signals
through two RJ45 connectors over two low cost Cat-5/5e/6 cables. The receiving unit is responsible for
equalizing transferred TMDS multimedia data and re-sending IR signals. The transmission distance
between the sending and receiving units can be up to 60m (200ft) under HD resolution (720p or 1080i) or
40m (130ft) under Full HD resolution (1080p). With 8-level equalization rotary control on the receiving unit,
users can adjust the equalization scale to the received TMDS signals, and therefore optimize the
transmission distance between source and destination.

FEATURES

● Support HDMI Deep Color & full 3D

● HDCP 1.3 compliant

● Extends the transmission distance up to 60m (200ft) from the sources under 1080i or 720p

● Extends the transmission distance up to 40m (130ft) from the sources under 1080p

● Provides independent DDC channel, fully HDCP compliant

● Minimizes the cable skew by adjustable 8-level equalization rotary control switch

● Embedded IR pass-through (38kHz) from RX to TX

● Pure unaltered uncompressed 7.1ch digital HDMI over UTP cable transmission

● Wall mounting housing design for easy and robust installation

● Perfectly integrated with other HDMI over Cat.X series products

The claimed transmission distance here is subject to the grade of installed cable(s), source
device and display.

For over Cat.X/COAX transmission, the cable(s) has to be solid, not stranded. Any keystone
jack along the transmission path will kill the transmission performance significantly!For
more information, please check HERE.
