FAQs
- If your PCs are running Windows OS: Connect two PCs to the input ports labeled 'A' of each input group on the KVM using two USB-C cables to enable MST mode. Connect two PCs to the 'A' inputs.&'B' or only with the input ports of each input group marked 'B' to disable MST mode.
- If your PCs are running MacOS: Connect 2 PCs to inputs 'A'.&'B' of each input group of the KVM with 4 USB-C cables.
- Hotkeys are triggered via a keyboard connected to the dedicated mouse or keyboard ports.
- The emulation programming is fixed and cannot be changed by the mouse. & Keyboard ports will be removed.
- Dedicated mouse & Keyboard ports should not be used for other types of USB devices.
- Use a powered USB hub to expand the number of USB 3.0 ports.
- If the wireless mouse/keyboard is "jumpy", use a USB extender to reduce the distance to the receiver.
- Please install 2 AAA batteries before using the remote control (batteries not included).
COMPATIBILITY INFORMATION
- Dedicated mouse & Keyboard ports have emulation programming. Second-generation chipsets have a "passthrough mode" to send special characters such as multimedia keys (play, pause, volume up/down, etc.), which significantly improves keyboard compatibility.
- Keyboard software such as Logitech Options, DAS Q, Corsair iCUE, etc., conflicts with emulation programming and limits the ability to use dedicated macro keys. We recommend using the KVM's USB 3.0 port as a workaround if this software is desired. The USB 3.0 port does not support emulation programming, and therefore the KVM will not recognize hotkey switching commands. Use a powered USB hub to extend USB connectivity if needed.
