INTRODUCTION
The EX-57VJ HDMI Extender over Single Cat.X with HDBaseT-Lite, Bi-directional IR & POC boosts
up your video/audio transmission distance up to 60m (198ft) in HDTV 1080p with 36-bit color depth. EX-
57VJ also supports the most advanced 3D video format complaint with HDMI specification and therefore
guarantees the highest 3D video compatibility on the market. With only one cost effective Cat.5/5e/6
cable, 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 or DVI enabled
TV sets or LCD PC monitors. With the advanced design for the latest HDMI technology, deep color video,
DTS-HD or Dolby TrueHD audio, and HDCP supports and compatibility are all further insured. This
flexibility makes HDCP compliant DVD players or PS3 transmit utmost high quality video and audio with
a greater distance at the minimal cost, when integrating several components apart. In addition, EX-57VJ
is also equipped with bi-directional IR pass-through path. These bonus features allow users to boost IR
control distance up to 60m (198 ft) and makes IR control possible through only single Cat.5/5e/6 cable
including HDMI signals. In addition, EX-57VJ also supports PoC (Power over Cable) which can power both
units from either TX or RX with power supply.
The EX-57VJ includes two units: transmitting unit EX-57VJ-TX and receiving unit EX-57VJ-RX. The
transmitting unit is used to capture the input HDMI / DVI signals with IR control packets and carry the
signals via one cost effective Cat.5/5e/6 cable. The receiving unit is responsible for equalizing the
transmitted HDMI signal and reconstructing IR signals. EX-57VJ offers the most convenient solution for
digital signage with long distance A/V transmission path, and is ready for your next HDMI generation and
applications!

(114ft) at 4K2K@30
Supports PoC(Power over Cable) which can power both units from TX or RX side with power supply
HDCP & EDID Bypass
CEC support
Auto equalization
Pure unaltered uncompressed 7.1ch digital HDMI over Cat.5/5e/6 cable transmission


The length depends on the characteristics and quality of the cables. Higher resolutions and
longer transmission distances require low skew cables (<25ns/100m) for best performance.
Unshielded CAT6 with metal RJ45 connectors is recommended.

You can buy any IR extension cables in the market that are compatible to the definition of the
IR sockets for the extender if necessary for replacement use. However, IR cables longer than
2m (6-ft) may not work.
Incorrect placement of IR Blaster and Receiver may result in the failure of the
IR extenders. Please check carefully before plugging in the IR extender to the
respective IR sockets. Warranty will not cover the damage.

NOTICE
1. All HDMI over CAT5 transmission distances are measured using Belden 1583A CAT5e 125MHz UTP
cable and ASTRODESIGN Video Signal Generator VG-859C & VG-870B.
2. Incorrect placement of IR Blaster and Receiver may result in the failure of the IR extenders. Please
check carefully before plugging in the IR extender to the respective IR sockets. Warranty will not
cover the damage.
3. The transmission length is largely affected by the type of Cat-5/5e/6 cables, the type of HDMI
sources, and the type of HDMI display. The testing result shows solid UTP cables (usually in the form
of 300m [1,000ft] bulk cables) can transmit a lot longer signals than stranded UTP cables (usually in
the form of fixed length patch cords). Shielded STP cables are better suited than unshielded UTP
cables. A solid UTP Cat-5e cable shows longer transmission range than stranded STP Cat-6 cable.
For long extension applications, solid UTP/STP cables are the only viable choice.
4. EIA/TIA-568-B termination (T568B) for Cat-5/5e/6 cables is recommended for better performance.
5. To reduce the interference among the unshielded twisted pairs of wires in Cat-5/5e/6 cable, one can
use shielded STP cables to improve EMI problems, which is worsen in long transmission.
6. Because the quality of the CAT5/6 cables has the major effect on how long the transmission limit
can achieve and how good is the received picture quality, the actual transmission range is subject
to one’s choice of Cat-5/5e/6 cables. For desired resolutions greater than 1080i or 1280x1024, a Cat-
6 cable is recommended.
7. 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.
