Troubleshooting
HDEX80-KVM
1. What can I do if the USB connection is not working?
- Check if you have connected the transmitter to your PC via a USB cable.
- Try connecting the USB cable to another USB port on your PC.
- Check if the LED indicator next to the USB port is in normal status (solid on/flashing). If not, please check if you have connected the USB cable properly.
- Try connecting the USB devices to the PC directly without using the KVM extender. Then check if the USB connection works.
2. My mouse and keyboard can work with the KVM extender, but other USB devices like a hard drive can't work. What should I do?
- Try plugging in the receiver with the included power adapter. (Neglect this step if you already did)
- Try plugging in your USB devices if they have an independent power supply.
- Check if the USB devices are compliant with USB 2.0 specification.
3. What can I do if there is no video output?
- Set the HDMI output resolution of your PC to 1080P.
- Check if you have chosen the right HDMI input channel on your display device.
- Check if the "status" LED indicators on the transmitter and receiver are in normal status (solid on).
- Try connecting the PC to the display device directly via an HDMI cable. Then check if there is any video output.
4. What can I do if the transmitter or receiver is not powered on?
- Use a new Cat cable, or check if your cable meets the standard. It is recommended to use a Cat5E/6/6A/7 cable, instead of Cat5 or flat cable.
- Check if the total length of your cable is within 80m/260ft.
- Check if the connectors at both ends of the cable meet the IEEE T568B standard.
- 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 note that the total length of the patch cables and the Cat cable should not be over 80m/260ft.
