Troubleshooting
No video or audio signal is being transmitted.
Verify that both the transmitter and receiver are powered on. Check that all HDMI and CAT6 cable connections are secure at both ends. Ensure the CAT6 cable is not damaged and is a CAT6 or higher specification. Try using a shorter known-good CAT6 cable for testing. Confirm the display is set to the correct input source.
Video quality is poor (e.g., flickering, pixelation, stuttering).
The issue may be with the CAT6 cable quality or length. Ensure you are using a certified CAT6 cable. If the distance is close to the maximum 165 ft (50 m), try a higher quality shielded CAT6 cable. Check for any kinks or damage in the CAT6 cable run. Ensure the source device is outputting a compatible resolution and refresh rate.
IR remote control functionality is not working.
Ensure the IR transmitter cable is correctly positioned to 'see' the IR receiver on the source device, and the IR receiver cable is correctly positioned to 'see' the remote control. Verify that the IR cables are plugged into the correct ports on both the transmitter and receiver units. Test the IR functionality with a known-good remote control.
The device is not working after a power surge or outage.
Unplug the power adapters from both the transmitter and receiver, wait 30 seconds, and then plug them back in. Check your power outlet to ensure it is functioning correctly.
