4. Operating Instructions
The TRENDnet TK-232DV KVM switch offers multiple methods for switching between connected computers.

4.1. Front Panel Switching
Press the corresponding 'PC' button on the front panel of the KVM switch to select the desired computer. The LED indicator above the button will illuminate to show which computer is currently active.
4.2. Keyboard Hot-Key Switching
You can switch between computers using keyboard hot-key commands. The default hot-key sequence is typically:
- Press the Scroll Lock key twice in quick succession, then press the number key (1 or 2) corresponding to the desired computer.
- For example, to switch to PC1, press Scroll Lock, Scroll Lock, then 1.
Refer to the Quick Installation Guide for advanced hot-key commands or to change the hot-key settings.
4.3. USB 2.0 Hub Functionality
The integrated 2-port USB 2.0 hub allows you to share USB peripherals between the connected computers. When you switch to a different computer, the USB devices connected to the hub ports will automatically switch to that computer.
