INTRODUCTION
The EX-57CLZ 4K-HDR HDMI 2.0 Extender over Single CAT6 with, Bi-directional IR & PoC boosts
up your video/audio transmission distance up to 70m (230ft) at 4K2K@60 and supports HDMI2.0 and HDCP2.2.
With only one cost-effective Cat.6 cable, users can readily extend signals from HDMI capable sources, such as
Apple TV, PlayStation, Xbox, PC, and laptop to distant display monitors including HDMI 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. EX-57CLZ is also equipped with
bi-directional IR pass-through path control. These bonus features allow users to boost IR control distance up to
70m (230ft) through only single Cat.6 cable with HDMI signals. In addition, EX-57CLZ also supports PoC (Power
over Cable) which can power both units from either TX or RX with power supply.
The EX-57CLZ includes two units: transmitting unit EX-57CLZ-TX and receiving unit EX-57CLZ-RX. The
transmitting unit is used to capture the input HDMI signals with IR control packets and carry the signals via one
cost effective Cat.6 cable. The receiving unit is responsible for equalizing the transmitted HDMI signal and
reconstructing IR control signals. EX-57CLZ offers the most convenient solution for digital signage with long
distance A/V transmission path.

[CAT6 ] /70m(230ft) [CAT5e] at 1080P60
Supports PoC (Power over Cable) which can power both units from TX or RX side with power
supply
Supports HDMI input loopback
HDCP 2.2/1.43& EDID Bypass

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.
