1. Introduction
The HDMI Extender over Single Cat5e/6 with IR extends high definition video and audio
signals and IR, at a distance of up to 164ft/50m over a single Cat5e/6 cable. Features
EDID management, which allows and encourages source and display “handshake” for
seamless integration. With only one cost effective Cat5e/6 cable, high definition
sources with HDMI outputs can be connected to high definition displays with HDMI
inputs over long distance. Deep color video, DTS-HD or Dolby TrueHD audio is
supported and compatible with the extender. In addition, the extender is also equipped
with bi-directional IR pass-through which allows for source or display control.
The extender includes two units: transmitting unit and receiving unit. The transmitting
unit is used to capture the HDMI input with IR signals and carries the signals via one
cost effective Cat5e/6 cable. The receiving unit is responsible for equalizing the
transmitted HDMI signal and reconstructing IR control signals. The extender offers the
most convenient solution for HDMI extension over a single Cat5e/6 with long distance
capability, and is the perfect solution for any application.

5.3 RX Equalizer Distance Adjust
If you see flickering or blinking image on the display, adjust the EQ switch to improve
the cable skew. MAX stands for the strongest HDMI signal level for the longest possible
transmission length while MIN stands for the weakest HDMI signal level for short
transmission length. Adjust the signal level from MIN to MAX until desired video quality
is displayed.

7. Connect and Operate
1. Connect a source (such as a Blu-Ray Player, game console, A/V Receiver, Cable or
Satellite Receiver) to the HDMI input on the Transmitting unit.
2. Connect a display such as an HDTV or HD Projector to the HDMI output on the
Receiving unit.
3. Connect a single Category 5e/6 up to 164ft/50m to the output of the Transmitting unit,
and the other end to the input of the Receiving unit.
4. For power, plug both the Transmitting unit and Receiving unit with the equipped
power supply.
5. Power on each device in the same sequence (receiver and transmitter will already be
powered on when either unit is plugged in.)
At this point the display connected should display the source signal connected to the
extender set. If no signal is being displayed, check the receiver EQ switcher. If a display
is having difficulty in receiving a signal, see EDID section and perform EDID learning or
access the display’s menu and adjust the resolution (lowest to highest until signal is
displayed). A 24 Hz vertical refresh rate may work better than 60 Hz or higher. Use the
source remote at the receiver emitter to test IR functionality. If the IR remote function is
not responding, check the emitters to ensure they are placed correctly and are plugged
into the correct IR jacks on the Extender set receiving and transmitting units.
