Steps of Regular Troubleshooting Routine
1. Power: Please make sure all devices are powered on (the source, extender set
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: Plug in and out 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 dierent resolutions.
Resolution and Transmission Range
1080P 4K@60 420
4K@30 444 4K@60 444

HDMI OUT 49ft 33ft 16ft
Cat 5e/6 197ft 115ft 115ft
Cat 6a/7 230ft 131ft 131ft
• 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.

Trouble Shooting
1. How to deal with video ash or cut o during the installation?
• Power indicator should be solid on and status indicator should be
blinking. If not, please check if the power adapter is well 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 well 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 to deal with a weak or not working IR signal?
• Make sure the IR cables are correctly installed according to the
Installation Instruction diagram 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)

3. How can I make the IR work with third party control devices?
• Please make sure the third party device follows our pin definition as
below:
• You can purchase an AV Access universal IR cable that will be compliant
with any third party device (Amazon ASIN: "B01MYX46IC").
4. How to use the RS 232 port in the extender?
The RS 232 port provides a channel to pass through protocol commands to
control third party devices such as your source or display. RS 232 uses the
three pins that are labeled transmitter, receiver and GND. Connect a host
computer or control system to the RS 232 connector. Please refer to the
following pin denition of RS 232 during your installation.
