If you encounter issues with your ATEN CE820 KVM Extender, refer to the following common troubleshooting steps:
- Fără afișare video:
- Check all HDMI cable connections between the source, local unit, remote unit, and display.
- Ensure both local and remote units are powered on.
- Verify the Cat6/6a cable connection between the local and remote units is secure and undamaged.
- Confirm the display is set to the correct input source.
- If using Long-Reach mode, ensure the DIP switch on the remote unit is correctly set.
- Try a different HDMI cable or display to rule out faulty components.
- No USB Functionality (Keyboard/Mouse):
- Ensure the USB cable from the computer to the local unit is securely connected.
- Verify the USB peripherals are correctly plugged into the USB Type A ports on the remote unit.
