7. Troubleshooting
If you encounter issues with your extender, please refer to the following common problems and solutions:
- No Video Signal on Remote Display:
- Verify that both the TX and RX units are powered on and their indicator lights are active.
- Check all HDMI cable connections between the source, TX, RX, and display.
- Ensure the Ethernet cable connecting the TX and RX units is securely plugged in and undamaged. Try a different Cat5e/6/7 cable if possible.
- Confirm the Ethernet cable length does not exceed 120 meters (394 feet).
- Press the RST button on both TX and RX units to reset them.
- Ensure your display supports 1080P resolution.
- KVM (Keyboard/Mouse) Not Responding:
- Ensure the USB A-A cable is correctly connected from your PC to the TX unit.
- Verify that your keyboard and mouse are standard USB 1.1 devices. Gaming peripherals or devices requiring higher USB versions are not supported.
- Try connecting the keyboard and mouse directly to the PC to confirm they are functional.
- Reset both TX and RX units using the RST button.
- Intermittent Signal or Poor Quality:
- Check the quality and integrity of your Cat5e/6/7 Ethernet cable. A high-quality, oxygen-free copper cable following the IEEE-568B standard is recommended.
