Operation
Switching Modes
The Yinker KVM Switch offers four convenient methods to switch between connected computers:
- Panel Button Switch: Press the corresponding 'PC1', 'PC2', 'PC3', or 'PC4' button on the front panel of the KVM switch to select the desired computer. The backlit indicator will show the active port.
- Wired Desktop Selector: Use the included wired desktop controller for extended switching convenience. Simply press the button on the selector to cycle through the connected computers.
- Hotkey Button: Utilize keyboard hotkeys for quick switching. The default hotkey commands are typically initiated by pressing the 'Scroll Lock' key twice, followed by the port number (e.g., Scroll Lock, Scroll Lock, 1 for PC1). Refer to the user manual for a full list of hotkey commands and customization options.
- Auto-Scan Switch: The KVM switch can be configured to automatically scan and switch between active computers at set intervals. Consult the user manual for instructions on enabling and configuring auto-scan mode.
