Setup Guide

Follow these steps to connect your TRENDnet TK-409K KVM Switch:

1. Connect Console Devices: Plug your VGA monitor, USB keyboard, USB mouse, 3.5mm speakers, and 3.5mm microphone into the corresponding 'CONSOLE' ports on the KVM switch.
2. Connect Computers: Use the provided KVM cables to connect each computer to the KVM switch. Each cable set includes VGA, USB, and audio connectors. Connect the VGA, USB, speaker, and microphone plugs from one KVM cable to the respective ports on your first computer and to a 'PC' port (e.g., PC 1) on the KVM switch. Repeat this for up to four computers.
3. Power On: Ensure all computers are powered on. The KVM switch draws power from the connected computers via the USB connections, so no external power adapter is required.

Operation

The TRENDnet TK-409K KVM Switch offers multiple methods for switching between connected computers:

• Front Panel Push Buttons: Press the numbered buttons (1, 2, 3, or 4) on the front of the KVM switch to directly select the desired computer.
• Keyboard Hotkey Commands: Utilize predefined hotkey combinations on your keyboard to switch between computers. Refer to the software utility (if installed) or the product's full manual for specific hotkey sequences. Common hotkeys often involve double-tapping a specific key like 'Scroll Lock'.
• Auto-Scan Function: The KVM switch supports an auto-scan interval (10-60 seconds) for monitoring computers. This feature can typically be activated via hotkey commands.

Audio functionality allows you to listen to music or use a microphone from one computer while actively working on another, providing flexibility in your workflow.

Troubleshooting

If you encounter issues with your KVM switch, consider the following general troubleshooting steps:

• Check All Connections: Ensure all VGA, USB, and audio cables are securely connected to both the KVM switch and the computers. Loose connections are a common cause of display or input issues.
• Verify Power: Confirm that all connected computers are powered on, as the KVM switch draws its power from their USB ports.
• Restart Devices: Try restarting the connected computers and the KVM switch (by unplugging and replugging the USB connections) to reset the system.
• Test Peripherals Directly: If a specific peripheral (keyboard, mouse, monitor) is not working, test it by connecting it directly to a computer, bypassing the KVM switch, to rule out a peripheral malfunction.
• Update Drivers: Ensure your computer's display and USB drivers are up to date.
