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 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

UTP/STP cables are the only viable choice.
Safety and Notice
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
than 1080i or 1280x1024, a Cat-6 cable is recommended.

The HDEXT1IR232 HDBasedT Lite Extender with
Bi-directional IR & RS-232 boosts up your video/audio transmission
distance up to 60m (198ft) in HDTV 1080p with 48-bit color depth.
HDEXT1IR232 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 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, HDEXT1IR232 is also equipped with bi-directional IR
pass-through path and RS-232 serial port control. These bonus features
allow users to boost IR control distance up to 60m (198 ft) and makes IR
control possible through only single CAT5/5e/6 cable including HDMI
signals. In addition, serial port offers the convenient path for interactive
application, such as touch panels.
The HDEXT1IR232 includes two units: transmitting unit
HDEXT1IR232-TX and receiving unit HDEXT1IR232-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 signals. HDEXT1IR232 offers the most
convenient solution for digital signage with long distance A/V
transmission path, and with 10G transmission width ready,
HDEXT1IR232 is ready for your next HDMI generation and applications!
