INTRODUCTION
The EX-57VJ-A HDMI Extender over Single Cat.X with HDBaseT-Lite, Bi-directional IR, POC &
ARC boosts up your video/audio transmission distance up to 60m (198ft) in HDTV 1080p with 36-bit color
depth. EX-57VJ-A 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-A 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-A also supports PoC (Power over
Cable) which can power both units from either TX or RX with power supply.
The EX-57VJ-A includes two units: transmitting unit EX-57VJ-A-TX and receiving unit EX-57VJ-A-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-A 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
Supports ARC on transmitter & receiver unit
HDCP & EDID Bypass
CEC support
Auto equalization

You can buy any IR extension cables in the market that are compatible to the definition of
the IR sockets for the matrix 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.
