A keyboard hotkey sequence consists of at least three specific keystrokes:

Hotkey = Ctrl+ Alt + [Command key]* Universal hotkey = ScrLK + ScrLk

* The command key is user-definable via the configuration dialog box

See Quick Reference Sheet

Each keystroke within a hotkey sequence should be pressed

within 2 seconds. Otherwise, the hotkey sequence will not be validated.

There are three methods to control your KVM Switch for PC and Audio/Mic channel selection: using (1) the face-panel push button, (2) a hotkey sequence or (3) the KVM Switcher Software.

Face-panel button

The face-panel button allows you a direct control over KVM switching operation. Simply press the button to switch to the corresponding PC port (and audio/mic channel, if binding is enabled). By default, PC port switching and audio/mic port switching are bound together.

You can use the face-panel button to switch to an empty port that is not connected with any computer. Normally, if you use keyboard hotkeys or the KVM Switcher software, you will not be able to switch to an empty port.

Keyboard hotkeys

User-definable hotkeys for PC selection: Hotkey sequence = Ctrl + Alt + [command key]* * Please refer to next section for keys that are qualified to be used as a command key

Universal hotkey for PC toggle-switching:

Both the universal hotkey, ScrLk + ScrLk and the user-definable hotkey, Ctrl + Alt + [command key] WILL NOT allow you to switch to an empty port that is not connected with any computer. To force your KVM to switch to an empty port, just press the face-panel button to switch.

Universal Hotkey sequence = ScrLk + ScrLk

* For other operating systems on PC such as Linux, you can still use this special hotkey to facilitate PC switching. This special hotkey is not available for Mac. HOWEVER, you can press button to switch in any case.

Each keystroke within a hotkey sequence should be pressed within 2 seconds. Otherwise, the hotkey sequence will not be validated.

After perform port switching, you have to wait till the KVM Switch icon shows forth the target port before you can perform next switching again. The KVM Switcher icon could be found on the system tray of your Windows desktop after its installation.

All the hotkeys are only functional after your PCs are booting into the OS. If you want to switch PC in the BIOS/preboot stage, press the face-panel button to switch.
