This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.

Introduction
Overview
LINK EXT70-4KUHDE is an HDBaseT Extender. It supports 4K@60
4:4:4 with HDR and HDCP 2.2 compliant, offers the distribution of
uncompressed UHD video, audio, power, and IR together up to
100m/330ft over a single Cat X cable.
With a feature set including transmission of uncompressed 4K@60Hz UHD
video, HDCP 2.2 compatibility, Dolby and DTS HD audio, bi-directional IR
control, it offers the added benefit of an incredibly low-profile for a greatly
reduced form factor behind the screen for even more convenience and ease
of installation at the display zone.
By the DIP switch of Audio Output on the receiver, it’s able to configure
the ARC channel feed by TV (with ARC support), or auxiliary S/PDIF Input
port. This unit also provides an HDMI audio de-embedding with phoenix
analog connector.
Its proprietary one way PoE technology ensures that the
transmitter unit powers the receiver unit, with visual LED indication for
power supply to units and signal status to show established connection
between connected devices.

Connections and Installations
1. Using quality HDMI cables, connect an HDMI source (such as Blu-ray,
games console, satellite/cable TV, media server etc.) to HDMI IN port of
Transmitter.
2. Connect the audio system in the figure to the AUDIO OUT port of the
Transmitter.
3. Connect a good quality, terminated Cat X cable between the HDBT
OUT of the Transmitter to the HDBT IN of the Receiver.
4. Connect the HDMI display device such as TV in the figure to the HDMI
OUT of the Receiver.
5. For two-way IR control of connected sources and displays from either
location, first, connect IR Emitters to the IR OUT ports of the
Transmitter and Receiver, and then insert IR Receivers into the IR IN
ports of the Transmitter and Receiver.
6. For the audio DIP switch output on the receiver, please refer to the
Audio DIP Switch Control Section.
7. Connect the included 12V power supply to the transmitter or receiver.
The PoE function carries power along the length of the cable to power
the other one.
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 within the signal. Power and Link are static lights. Status should
be blinking.

Audio DIP Switch Control
The Extender features an Audio DIP Switch that can be used to control audio
output.
ARC Mode
Note: When you want to configure ARC channel feed by TV:
Ensure AV System and TV support ARC function and CEC should be
ON.
Connect AV System and TV through ARC- enabled HDMI Ports.
Connect the AV System to HDMI IN port of Transmitter, connect a TV to
HDMI Out port of Receiver. Switch the DIP switch to ARC mode, switch TV to
the audio source you want to be sent back, and set the AV System to the
ARC channel. The audio signal of TV through HDMI OUT port will be
transmitted to the AV System connected to HDMI IN Port of Transmitter.
(Figure 1)
TOSLINK IN Mode
When you configure the auxiliary optical input, please switch it to TOSLINK
IN mode and connect an audio system to the TOSLINK IN port of Receiver,
and an Audio System such as an AV Receiver to TOSLINK OUT port of
Transmitter. Audio signal from TOSLINK IN port will pass through to
TOSLINK OUT port. (Figure 2)

IR Control
IR pass-through function allows you to control the source from the display
location or control the display from source location.
Control the Display
In this case, IR IN port in Transmitter is connected to a broadband IR
receiver and IR OUT port in Receiver is connected to an IR emitter. You
can control the TV from the DVD location with the TV remote.

Control the Source
In this case, IR OUT port in Transmitter is connected to an IR emitter and IR
IN port in Receiver is connected to a broadband IR receiver. You can
control the DVD player from the TV location with the DVD remote.

Trouble Shooting
Troubleshooting Steps
1. Power: Please make sure all devices are powered on (the sources,
extender and display).
2. Indicator: Please make sure LED indicators of the extender 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: Plug in and unplug HDMI/Cat X cable or try another HDMI/Cat
X cable. Please make sure the specific cable length is within the
transmission range in the user manual Specification section. Cat
5e/6/6a/7 cable is recommended, do not use Cat 5 cable. Please make
sure the two connectors of one Cat X cable are the same standard
(EIA/TIA 568B).
5. Compatibility: Please test other source and display devices to
determine if it is a compatibility issue.
