TroubleShooting

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 different resolutions.

Resolution and Transmission Range

Resolution Cable| 1080P| 4K@60 420
4K@30 444| 4K@60 444
HDMI IN| 49ft| 33ft| 10ft
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).
Compatibility: Please test other source and display devices to determine if it is a compatibility issue.

  • Standard HDMI 2.0 cable is required when 18G signal (4K@60Hz 4:4:4 8bit) is being transmitted.

Typical Question

  1. How to deal with 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 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. Enable 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 RS232 port in the extender?
    The RS232 port provides a channel to pass through protocol commands to control third party devices such as your source 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 your installation.
