The integrated USB 3.0 hub allows you to share two USB 3.0 peripherals (connected to the 5G ports) and four USB 2.0 HID peripherals (connected to the HID ports) between the connected computers. Devices connected to these ports will function as if directly connected to the currently selected host computer.

5.4. Audio Support

The KVM switch supports both digital audio (via HDMI, 7.1 Channel Audio) and separate 3.5mm stereo analog audio (2 Channel Audio). Ensure your displays and sources support the desired audio format for full compatibility.

6. Maintenance

To ensure the longevity and optimal performance of your KVM switch, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid or aerosol cleaners.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area. Do not block any ventilation openings.
• Cable Management: Keep cables organized and untangled to prevent damage and ensure proper airflow. Avoid excessive bending or crimping of cables.
• Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your KVM switch, refer to the following common problems and solutions:

• No Display or Incorrect Resolution:
  • Ensure all HDMI cables are securely connected to both the KVM switch and your computers/monitors.
  • Verify that your HDMI cables are rated for 4K 60Hz if you are using 4K displays. Longer cables (e.g., over 3m/10ft) may require higher quality or active cables.
  • Check the display settings on your computers to ensure they are configured for the correct resolution and refresh rate.
  • Try power cycling the KVM switch and monitors.
• Keyboard/Mouse Not Responding:
  • Ensure the USB Type-B cables are securely connected from the KVM switch to your computers.
  • Verify that your keyboard and mouse are connected to the designated HID USB ports.
  • Try connecting the keyboard/mouse directly to the computer to confirm they are functional.
  • Some specialized keyboards/mice with advanced features may require direct connection or specific drivers.
• USB Devices Not Detected:
  • Ensure the USB Type-B cables are connected from the KVM switch to your computers.
  • Verify that the USB device is connected to the appropriate 5G USB 3.0 port.
  • Some high-power USB devices may require an external power source or a powered USB hub connected to the KVM's 5G port.
• Audio Issues:
  • Check all 3.5mm audio cable connections.
  • Verify audio output settings on your computers.
  • Ensure your monitors or audio devices support the HDMI audio format being sent.
• Slow Switching Time:
  • The KVM switch is designed for fast switching. If experiencing delays, ensure EDID and HDCP emulation are functioning correctly.
