humidity.
All of the power switches, plugs, sockets and power cords should be insulated and
safety.
All devices should be connected before power on.
Use shielded straight-thru CAT5e/CAT6a cable with TIA/EIAT568B terminations for
good transmission effect.

3.3 Connection Procedure
Step1.Connect HDMI source (such as Blue-ray DVD) to HDMI IN port of HDBaseT
Transmitter with HDMI cable.
Step2.Connect HDBT OUT port of HDBaseT Transmitter and HDBT IN port of LG-HRx,
with single CAT5e/CAT6a cable.
Step3.Connect HDMI displayer (such as HDTV) to HDMI OUT port of LG-HRx with
HDMI cable.

Step4.Both t HDBaseT Transmitter and LG-HRx have IR IN and OUT. When one end is
used as an IR receiver, the signal sent from the end can only be transmitted via
the other end.
For example: When “IR IN” of HDBaseT Transmitter connects with an IR
receiver, the IR transmitter must connect to IR OUT of LG-HRx.
Step5.Connect the RS232 port of the devices to be controlled and the LG-HRx or the
Transmitter.
Step6.Connect with DC24V power adaptor(s) (One is enough if HDBaseT Transmitter
is connected with adapter as its PoH function).
3.4 Twisted Pair Cable Connection
The twisted pair used in this extender MUST be a straight-through cable.
Notice: Cable connectors
MUST be metal one, the
shielded layer of cable
MUST be connected to the
connector’s metal shell, to
make a better transmission.

6. Troubleshooting & Maintenance
No image on display:
Ensure that the display device has been set to the correct input.
Ensure that the HDMI cables used for both the source/transmitter and the
receiver/display are properly connected and are working. Test the HDMI cables
directly from a source to display and ensure their operation.
Ensure that the CAT5e/CAT6a cable has not been damaged and that it has been
terminated correctly with T568B on both ends. Atemporary length of CAT5e/Cat6
can be used for testing to ensure that the devices are all compatible and working
properly.
Ensure proper grounding of the power supply.
Known issues with HDMI 1.2 source devices:
Older compatibility (HDMI 1.2) may result in HDBaseT transmission issues.
Please contact Technical Support of your director for a solution to these issues.
Color lose or poor picture quality:
Ensure that the HDMI cables used for both the source and transmitter and the
receiver and display are properly connected and are of good quality. Test the
HDMI cables directly from a source to display and ensure their picture quality.
Ensure proper grounding of the power supply.
If the static becomes stronger or picture quality becomes worse when connecting
the video connectors, this may be due to improper grounding.
Check the grounding and make sure all the components are properly grounded
to a common ground. Improper grounding may cause damage to the receiver.
If your problem persists after following the above troubleshooting steps, seek further
help from authorized dealer or our technical support.
