Product Introduction
Thanks for choosing the 4K HDMI Extender which consists a transmitter and a
receiver. The extender is designed to extend 4K@60Hz 4:2:0 HDMI video to distance
up to 40 meters (131 feet) and 1080P@60Hz video to distances up to 70 meters (230
feet) over a single CATx cable. Bi-directional Power over Cable (PoC) feature allows
the transmitter or receiver to be powered by each other without the need for a nearby
AC power outlet. It supports stereo and multichannel audio on the HDMI ports. In
addition to the audio embedded in the HDMI input stream, the audio is simultaneously
de-embedded to an analog audio output and an S/PDIF audio output.
The extender supports RS232 pass-through to control source or display devices
remotely. It also supports CEC pass-through. Moreover, it provides two RELAY ports
for controlling relay device such as the rise and fall of the projector screen.
Features
Supports HDMI 1.4 and the HDMI video resolution up to 4K@60Hz 4:2:0.
Supports HDCP pass-through and up to HDCP 2.2 version.
Extends 4K@60Hz 4:2:0 signal up to 40m and 1080P@60Hz signal up to 70m via a
single CATx cable.
Supports CEC pass-through.
Supports bi-directional PoC.
Supports bi-directional RS232 pass-through.
Supports RS232 relay control.
Supports audio de-embedding.

Transmitter Panel Description
1. Power LED: The LED illuminates green when power is applied and is off when no
power is present.
2. LINK LED: The LED illuminates blue when there is a valid HDBaseT connection
with the receiver. The LED is off when there is no valid link.
3. HDMI LED: The LED illuminates blue when there is HDMI video input with HDCP.
It will blink blue when there is HDMI video input without HDCP and will be off
when there is no HDMI video traffic.
4. RS232: 3-pin terminal block for bi-directional RS232 pass-through or RS232 relay
control.
5. L+R OUT: 3-pin terminal block to connect an audio play device (e.g. amplifier) for
audio de-embedding from HDMI input stream.
6. SPDIF OUT: Toslink connector to connect an audio play device (e.g. amplifier) for
audio de-embedding from HDMI input stream.
7. HDBT OUT: RJ45 port to connect the HDBT IN port of receiver by CATx cable.
The HDCP LED illuminates green when the video contains HDCP content, or
blinks green when the video has no HDCP content. The LINK LED illuminates
orange when there is a valid HDBaseT link between the transmitter and the
receiver.
8. HDMI IN:Type-A female HDMI input port to connect an HDMI source device.
9. DC 24V: Locking power port for 24V DC power adapter connection.

RS232 Relay Control
In addition to bi-directional RS232 pass-through, the two RS232 ports of the
transmitter and receiver can be used for controlling relay device.
Connect any RS232 port to the control device (e.g. PC) with RS232 cable, and then
install RS232 control software. The relay device can be controlled by sending RS232
commands. Here take the software CommWatch.exe as example:
Double-click the software icon to run this software.
The main view is shown as below:
Baud rate: 9600; Data bit: 8; Stop bit: 1; Parity bit: none.
