5. Operating Instructions

5.1 Switching Between Computers

The KVM switch offers two methods for switching between connected computers:

• Panel Button: Press the 'SW' button located on the front panel of the KVM switch to toggle between PC1 and PC2. The LED indicator (PC1 or PC2) will illuminate to show the active computer.
• Wired Desktop Controller: Connect the provided wired desktop controller to the 'Control' port on the front of the KVM switch. Press the button on the desktop controller to switch between PC1 and PC2. This allows for convenient switching if the KVM unit is placed out of reach.

On Windows, you can typically press Windows + P and select your desired display mode.

• Connect wired or wireless keyboards and mice.
• Connect printers, scanners, webcams, and USB flash drives.
• The KVM's 12V DC power adapter helps ensure stable operation for high-power USB devices like external hard drives.

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. Avoid liquid cleaners or abrasive materials.
• Ventilation: Ensure the KVM switch is placed in a well-ventilated area to prevent overheating. Do not block the ventilation openings.
• Cable Management: Organize cables to prevent strain on ports and accidental disconnections.
• Power Supply: Always use the provided 12V DC power adapter. Using an incorrect power supply can damage the device.
• Storage: When not in use for extended periods, store the KVM switch in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

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

• No Display on Monitors:
  • Ensure all HDMI cables are securely connected from both computers to the KVM and from the KVM to the monitors.
  • Verify that each computer has three HDMI cables connected to the KVM.
  • Confirm that your computer's graphics card supports triple monitor output.
  • Check if the KVM switch is powered on and the correct PC is selected (indicated by the LED).
  • Try restarting the KVM switch, monitors, and computers in sequence.
• Poor Video Quality or Incorrect Resolution (e.g., Not 4K@60Hz):
  • Ensure both your signal source (computer) and HDMI cables support 4K@60Hz. Lower quality cables or sources may limit resolution.
  • Avoid using HDMI to DisplayPort or HDMI to DVI/VGA adapter cables, as these may not support the full resolution or refresh rate.
  • Check your computer's display settings to ensure the correct resolution and refresh rate are selected.
• USB Devices Not Working (Keyboard, Mouse, etc.):
  • Ensure the USB 3.0 Type-A to Type-A cables are securely connected from both computers to the KVM.
  • Verify that the USB devices are properly plugged into the KVM's USB 3.0 OUT ports.
  • If using high-power USB devices (e.g., external hard drives), ensure the 12V DC power adapter is connected and providing sufficient power.
  • Try connecting the USB device directly to the computer to confirm it functions independently.
• Switching Delay or Instability:
  • Ensure all cables are firmly connected. Loose connections can cause intermittent issues.
  • Verify the 12V DC power adapter is correctly connected and functioning.
  • Note that keyboard shortcuts (hotkeys) are not supported by this KVM switch; use the panel button or wired controller for switching.
