- 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.
- 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.
An HDMI extender consists of a Transmitter(TX) and a Receiver(RX) and it converts HDMI signals into different forms for a longer run.
4KEX70-H2 is an HDBaseT HDMI extender.
- Firstly, the transmitter and receiver shall be connected directly via an Ethernet cable.
- Secondly, connect your source device to the Transmitter via an HDMI cable; connect your TV or monitor to the receiver via an HDMI cable.
- Lastly, power your extender with the adpater. Then it shall work fine. For more information, check the product manual.
This unit only supports direct connection from transmitter to receiver with a single ethernet cable. So it won’t work if you connect it to a switch. See if this is what you are looking for – HDMI over IP extender.

I'd give it more stars if I could. I needed to run a monitor 32 meters from the computer at 4k 60Hz over a Cat 6a cable. I plugged these in both ends and it fired up perfectly the first time, no messing with anything or tweaking settings, it simply works. I can't perceive any loss of fidelity or lag and I'm using this as my primary daily computer. It's crazy that I have trouble finding regular HDMI cables that reliably push 4k 60Hz and this manages to do it over 30+ meters. Anyway, I simply can't recommend this enough. Well engineered boxes that feel good in the hand. Nice extra touches like including mounting brackets and screw in power connector.
Used this to send 4k from a Virgin V6 box across about 5m of CAT6 cable and it works a treat. Very easy to set up and has been running about 2 months so far with no problems.
Work great for my folks New TV and due to size needed to route equipment to another cabinet where the amp was. I've run Cat 5E/6 Ethernet cable before so I suggested this route to avoid any issues with RF signals and potential delays for sound. Have been working great. If you want to minimize your holes you can install with bulk cable and put ends on after routing cable. Otherwise use long enough Ethernet cable for your job and no need to mess with connectors. I used Outdoor rated Cat 6 cable as I use it for other jobs as well helping others. New Full Copper 1,000 ft Cat6 Ethernet Cable / Wire 1,000ft Cat-6 Waterproof Outdoor / Direct Burial / Underground ~ VIVO Platinum Tools 100054C Clamshell EZ-RJPRO HD Crimp Tool This tool is very easy to use and it is a few bucks more but works great with the ends listed next. Platinum Tools 100010C EZ-RJ45 Cat 6+ Connectors are super easy to use and I don't even test the cables any more as I haven't had any issues with these. Easy to see if you have each wire in the correct spot. If you would like to run wired jobs make the leap and buy this or similar equipment and you should have no problem at all.
