INTRODUCTION
FEATURES
The HDEXT1-4KHDR 4K-HDR HDMI Extender over Single CAT5/5e/6 with HDBaseT-Lite, RS-232,
Bid-directional IR &PoC boosts up your video/audio transmission distance to 60m (198ft) in HDTV 1080p with
48-bit color depth and 35m (114ft) at 4K-HDR. HDEXT1-4KHDR has new generation technology which makes
sure the HDBaseT extender can support HDMI2.0a and HDC2.2. HDEXT1-4KHDR 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 CAT5/5e/6 cable, users can readily extend HDTV sources
from DVD players, Blu-ray Disc players, PS4, 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. HDEX1-4KHDR is also equipped with bi-directional IR pass-through path and RS-232 serial
port control. These bonus features allow users to boost RS-232 and IR control distance up to 60m (198ft) through
only single CAT5/5e/6 cable with HDMI signals. In addition, HDEXT1-4KHDR also supports PoC (Power over
Cable) which canpower both units from either TX or RX with power supply.
The HDEXT1-4KHDR includes two units: transmitting unit HDEXT1-4KHDR-TX and receiving unit
HDEXT1-4KHDR-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 CAT5/5e/6 cable. The receiving unit is responsible for equalizing the
transmitted HDMI signal and reconstructing IR and serial control signals. HDEXT1-4KHDR offers the most
convenient solution for digital signage with long distance A/V transmission path.
* HDR = High Dynamic Range
** The video bandwidth of 4K2K@60 4:2:0 10bits (HDR) is 384 MHz, and the 4K2K@60 4:4:4
8bits is 594MHz.

HDMI PIN DEFINITION
HARDWARE INSTALLATION

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.
