6.1 Switching Methods

The KVM switch offers two convenient ways to switch between connected computers:

• Button Switching: Simply press the corresponding input selection button (S1, S2, S3, or S4) on the front panel of the KVM switch to switch to the desired computer.
• Hotkey Switching: Use keyboard hotkeys for quick switching without reaching for the KVM unit. The default hotkey sequence is typically Scroll Lock, Scroll Lock, then the number corresponding to the PC (e.g., 1 for PC1, 2 for PC2, etc.). Refer to the full manual for advanced hotkey commands and customization.

8. Troubleshooting

If you encounter issues, please refer to the following common problems and solutions:

• No Display/Black Screen:
  • Ensure all DisplayPort cables are securely connected to both the KVM switch and your monitors/computers.
  • Verify that the KVM switch is powered on and the correct input is selected.
  • Check if your monitors are set to the correct DisplayPort input.
  • Try restarting the KVM switch and then the computers.
  • Ensure your graphics drivers are up to date on all connected computers.
• Keyboard/Mouse Not Working:
  • Ensure the USB 3.0 cables from your computers are connected to the corresponding USB 3.0 input ports on the KVM switch.
  • Verify that your keyboard and mouse are connected to the dedicated console USB ports on the front of the KVM switch.
  • Try connecting the keyboard/mouse directly to the computer to confirm they are functional.
  • Some specialized gaming keyboards/mice may require direct connection or specific drivers; try a standard keyboard/mouse to test.
• Intermittent Connection/Flickering Display:
  • Use high-quality DisplayPort 1.4 certified cables, especially for 8K resolutions.
  • Reduce the resolution or refresh rate to see if the issue persists.
  • Ensure there are no loose connections.
• Hotkey Not Responding:
  • Ensure the keyboard is connected to the dedicated console USB port.
  • Verify the hotkey sequence is correct (e.g., Scroll Lock, Scroll Lock, then number).
  • Some software or operating system settings might interfere with hotkeys; try disabling any conflicting hotkey utilities.

9. 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 KVM switch. Do not use liquid cleaners or aerosols, as they may damage the device.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block any ventilation openings.
• Storage: When not in use for extended periods, store the KVM switch in a cool, dry place away from direct sunlight and extreme temperatures.
