INTRODUCTION
The EX-57V2K-U HDBaseT 2.0 Extender with RS-232, Bi-directional IR, Ethernet, PoC &
USB2.0 boosts up your video/audio transmission distance up to 100m (330ft) in HDTV 1080p
with 48-bit color depth or 80m (264ft) at 4K2K@60 4:2:0 8bit. EX-57V2K-U also supports the
most advanced 3D video format complaint with HDMI specification and therefore guarantees the
highest 3D video compatibility in the market. With single 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 support 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-57V2K-U is also equipped with bi-directional IR pass-through
path, USB2.0 and RS-232 serial port control. These bonus features allow users to boost IR
control distance up to 100m (330ft) through only single Cat.5/5e/6 cable including HDMI signals.
In addition, serial port and USB2.0 offer the convenient path for interactive application, such as
touch panels. In addition, EX-57V2K-U also supports PoC (Power over Cable) which can power
both units from TX or RX with power supply.
The EX-57V2K-U includes two units: transmitting unit EX-57V2K-U-TX and receiving unit
EX-57V2K-U-RX. The transmitting unit is used to capture the input HDMI / DVI signals with
control packets. The receiving unit is responsible for equalizing the transmitted HDMI signal and
reconstructing IR and serial control signals. EX-57V2K-U offers the most convenient solution for
digital signage with long distance A/V transmission path, and with 10G transmission bandwidth
ready, EX-57V2K-U is ready for your next HDMI generation and applications!

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.

HARDWARE INSTALLATION
1. Connect a HDMI or DVI source (such as a Blu-ray Disc player) to the transmitting unit
EX-57V2K-U-TX.
2. Connect a HDMI or DVI display (such as a LCD TV) to the receiving unit EX-57V2K-U-RX.
3. Connect IR Blaster/Receiver to both TX and RX units.
4. Connect USB Host/Device to both TX and RX units
5. Connect audio source to TX and audio receiver/speaker to RX unit.
6. Connect a Cat-5/5e/6 cable between the transmitting and receiving units.
7. Make sure this Cat-5/5e/6 cable is tightly connected and not loose.
8. Plug in 24V DC power supply unit to the power jack of the transmitting unit EX-57V2K-U-TX.

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). 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 1080p, 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.
