5. Operating Instructions

5.1 Keyboard and Mouse Sharing

Once connected, your primary keyboard and mouse (connected to one of the computers) will automatically control both systems. To switch control between computers, simply move your mouse cursor to the edge of one screen, and it will seamlessly transition to the other screen, allowing you to control the second computer. The keyboard input will follow the active mouse cursor.

5.2 File Transfer and Clipboard Sharing

The KM Link Cable supports direct file transfer and clipboard sharing between the two connected computers.

• Clipboard Sharing: Copy text, images, or other data from one computer's clipboard (e.g., using Ctrl+C) and paste it directly onto the other computer (e.g., using Ctrl+V). This works across various clipboard formats, including text, images (JPG), and documents (WORD, PPT, TXT).
• File Transfer: Drag and drop files or folders directly from one computer's desktop or file explorer to the other computer's desktop or an open folder. The high-speed USB 2.0 connection (up to 480Mbps) ensures efficient data transfer.

The device also supports hot keys and hot click areas for quick access to these functions, providing a more convenient alternative to traditional drag-and-drop methods across monitors.

5.3 Multi-language Auto-recognition

The KM Link Cable automatically recognizes and supports 10 common languages without requiring manual configuration on your computer. This includes English, Chinese, Japanese, French, German, Italian, Spanish, Portuguese, Russian, and Korean, simplifying usage in diverse linguistic environments.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Avoid liquid cleaners or abrasive materials.
• Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Handling: Avoid bending the cable sharply or applying excessive force to the connectors to prevent damage.

7. Troubleshooting

• Device Not Detected:
  • Ensure both USB connectors are fully inserted into active USB 2.0 ports on both computers.
  • Try connecting to different USB ports on each computer.
  • Restart both computers and reconnect the cable.
• Keyboard/Mouse Sharing Not Working:
  • Verify that the device is detected by both operating systems (check device manager).
  • Ensure your mouse cursor is moved to the very edge of the screen to initiate the switch.
  • Confirm that the LED indicators on the KM Link module are lit.
• File Transfer/Clipboard Sharing Issues:
  • Ensure both computers recognize the KM Link Cable.
  • Check if any security software or firewalls on either computer are blocking data transfer.
