- Check if the “Link” LED indicator is solid on. Also, check if the “HDCP” LED indicator is solid on or blinking.
- Make sure the source device and the display device are powered on. And make sure the source device is outputting video signal while the correct HDMI input channel is selected on the display device.
- Connect the source device to the display device directly via an HDMI cable, then set the source resolution to 4K@30Hz or 4K@60Hz 4:2:0. If these two resolutions are not available, then set to 1080P. After you set the default resolution, please re-connect the source device and the display device to the HDMI extender.
- Make sure all of your HDMI cables work normally. You can connect the source to the display device directly via one of these HDMI cables, to check if video can be shown normally on the display.
- It is recommended to use a Cat5E/6/6A/7 cable, instead of Cat5 or flat cable.
- Please make sure the total length of your cable is less than 70m/230ft for 1080P, 40m/131ft for 4K resolution.
- Please make sure the connectors at both ends of the cable meet the IEEE T568B standard.
- Use a new cable, or try crimping your Cat cable connectors according to the IEEE T568B standard.
- If you need to use patch cables at both ends, the length should be as short as possible, no more than 5m/16ft. Please ensure all connectors meet the same standard (IEEE T568B). Also, please note that the total length of the patch cables and the Cat cable should not be over 70m/230ft.
- Check if your IR connection method is correct. The IR receiver cable needs to be connected to the “IR In” port at one end, and the IR emitter cable needs to be connected to the “IR Out” port at the other end. Please note that the 3.5mm cable connectors need to be fully inserted into the IR ports.
- Check if you use the remote controller correctly and if you place the IR emitter head correctly. When you use the remote controller, it needs to be directly facing the IR receiver head. Besides, the IR emitter head should be placed closely to the IR receiving window of the controlled device.
- Try controlling the source device directly via your remote controller, without using the HDMI extender. Then check if the IR connection works.
- Check if the connection method of the RS232 cable between the HDMI extender and the control/controlled device is correct. It should be “TX-RX, RX-TX, GND-GND”.
- Perform an RS232 loopback test to see if the HDMI extender’s RS232 pass-through function can work normally.
- Try connecting the control device and the controlled device directly without using the HDMI extender. Then check if the RS232 connection works.

Michael Randle –
Great set up for long runs
We have a downstairs home theater with a remote receiver upstairs. It’s ~200′ of cabling from the computer downstairs near the TV up to the receiver and 200′ back down to the TV. HDMI runs at that length are amplified/unidirectional and very expensive (~$600 last time we had a run replaced). Now that one of the HDMI cables started having issues instead of shelling out a bunch of cash to have someone fish around in our soffit and insulation I used these little boxes and some pre-existing CAT5e already pulled to both locations.
I’m only running 1080/60p but the signal has been rock solid. Setup was super easy – especially with PoE and only one power adapter required. IR relay is working fine as well. Very impressed by this little piece of kit.
