6. Maintenance
To ensure optimal performance and longevity of your extender:
- Keep the units in a cool, dry, and well-ventilated area.
- Avoid exposing the units to direct sunlight, high temperatures, or excessive humidity.
- Clean the units with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Ensure all cable connections are secure and free from damage.
7. Troubleshooting
If you encounter issues, please refer to the following common solutions:
- No Video Output:
- Ensure all HDMI cables are securely connected to both the source and display, and to the extender units.
- Verify that the Cat5e/6/7 Ethernet cable is properly connected between the TX and RX units and is not damaged.
- Confirm that the power adapter is connected to the TX unit and the unit is receiving power.
- Test with a shorter, known-good Ethernet cable to rule out cable issues.
- Ensure your display is set to the correct HDMI input.
- Keyboard/Mouse Not Responding:
- Check that the USB cable is securely connected from your source PC to the USB IN port on the TX unit.
- Ensure your keyboard and mouse are connected to the KVM USB 2.0 ports on the RX unit.
- Avoid using 5.8GHz wireless keyboards/mice, as they may not be compatible. Wired or 2.4GHz wireless peripherals are recommended.
- Try connecting the keyboard and mouse directly to the source PC to confirm they are functional.
- Restart both the source PC and the extender units.
- Intermittent Signal/Flickering Video:
- Ensure the Cat5e/6/7 cable is of good quality and meets specifications for the distance.
- Check for any sources of electromagnetic interference near the Ethernet cable.
- Verify that the HDMI cables are not excessively long or damaged.
