KMS-U314, KM Switch
The KM Switch, KMS-U314, allows users to share one set of keyboard, mouse, audio, and USB peripherals among four USB-connected computers. Simply press a button or issue hotkey commands to select your desired PC for access control.
USB Switcher Application
A unique tracking system enables USB devices to operate independently or concurrently. For example, the USB tracking function allows KM Switch users to choose whether USB devices (such as flash drives, printers, or scanners) switch along with the selected PC port. Dedicated USB 3.0 ports on both the front and rear of the unit accommodate both long-term and temporary USB peripheral connections, allowing users to easily attach or detach devices. This is particularly useful for transferring files from one computer while operating another.
The KMS-U314 offers real-time USB HID ports for seamless switching and USB 3.0 ports for high-speed data transfer.

Independent Audio Switching
The audio function allows users to choose whether the audio port switches with the selected USB computer port or not follow the USB port switching. This is useful for listening to audio from one specific computer while working on another.
Mouse Roaming Functionality with Flexible Preset Screen Layouts
The Mouse Roaming Switching Function allows users to switch between computers by moving the mouse cursor across screen borders—an efficient and modern method of switching. Simply glide the cursor from one monitor to another to switch keyboard, mouse, audio, and USB devices - no hotkeys or button presses required.
Screen Layouts:
* Four common 4-screen layout presets are available for 4 x 1, 2 x 2, 1 + 3 and 1 x 4 video wall setups.
** Four 3-screen layout presets options are also available.
