Introduction
Overview
LINK EXT40-4KUHD is a slim HDBT transmitter receiver set with HDCP 2.2
compliant. It supports resolutions up to 4K@60Hz 4:4:4 8bit, transporting Ultra
HD/4K video with HDR, audio, bi-directional IR and power up to 131ft (40m) and
1080P signals up to 230ft (70m) over a single CATX cable.
EXT40-4KUHD features bi-directional PoCC, requiring only one
power adapter connected to either transmitter or receiver to power both units. Bi-
directional IR pass through allows users to control the source at the display location
or control the display at the source location with ease. RS232 pass through
supports serial communication.
The transmitter and receiver are easy to install. They are space saving and offer
ideal solutions for homes, ofces, digital entertainment centers, control centers,
conference rooms, schools and corporate training environments.

1. Connect an HDMI source (such as Blu-ray player, games console, STB, Apple
TV etc.) to the HDMI IN port of the Transmitter via an HDMI cable.
2. Connect the Transmitter to the Receiver via a Cat X cable on the HDBT ports.
3. Connect an HDMI display to the HDMI OUT port of the Receiver.
4. Connect the IR emitter and IR receiver to the Transmitter and the Receiver
respectively. Users can control the source at the display location or control the
display at the source location as required, please refer to the diagrams in IR
Pass Through Section.
5. Connect the power supply to either the Transmitter or Receiver to power both
units.
Check Power, Status, and HDCP & Link lights are illuminated on both units to indicate
successful connection, with a lit HDCP light illustrating the presence of encryption

The RS232 port provides a channel to pass through protocol commands to control
third party devices such as user'ssource or display. RS232 uses the three
pins that are labeled transmitter, receiver and GND. Connect a host computer or
control system to the RS232 connector. Please refer to the following pin definition
of RS232 during installation.

and display).
2. Indicator: Please make sure LED indicators of the transmitter and receiver are
normal according to user manual.
3. Devices: Please make sure picture can be shown normally when connecting
source to display devices directly.
4. Cable: Unplug and plug in HDMI/Cat X cable or try another HDMI/Cat X cable.
•Please make sure the specific cable length is within the transmission range
listed in below table based on different resolutions.

Troubleshooting Steps

19
1. How can I fix video flash or cut off during the installation?
•Power indicator should be solid on and status indicator should be blinking. If
not, please check if the power adapter is securely connected.
• Link indicator should be solid on. If it is blinking or off, it is likely a problem
with your Ethernet cable, please change to a qualified cable (Cat5e/6/7,
EIA/TIA 568B) and ensure the cable length is within the maximum distance
(230ft for 1080P, 131ft for 4K).
• HDCP indicator should be solid on or blinking. If it is off, it means no signal
pass through, please check if the HDMI cables are securely connected to
the source and TV, and the Ethernet cable that connects transmitter to
receiver is normal. Try a better HDMI cable or Ethernet cable.
2. How can I fix the IR signal if it is weak or not working?
• Make sure the IR cables are correctly installed according to the diagrams in
IR Pass Through section above.
• Check if the IR emitter head is secured over the center of the device IR
receiver window. The best position may vary depending on the device,
please refer to the device user manual. If the signal is weak, please try to
adjust the position.
•Pay attention to the control angle and distance as below. The control signal
will be better when your controller is pointed at the IR receiver head directly.
Enabled Angle 0° 30°(Horizontal) 15°(Vertical)
Distance 26ft (Max) 15ft (Max) 10ft (Max)
