AdderView AVS-4214

Secure KVM switch for sharing dual-head 4K video, USB keyboard and mouse, plus analog audio between four computers spanning multiple security classification levels.


  • Uni-directional keyboard, video, mouse and audio data paths
    • Uni-directional optical diodes ensure data paths travel in only one direction, thus preventing data leakage through shared peripherals. A uni-directional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.
  • Channel identification
    • Reduce the chances of operator error by displaying a name for each channel and its security classification on the E-paper display. The color of the channel LED may also be configured to reflect the security classification.
  • No shared RAM between ports
    • The keyboard and mouse processor is powered down and reset at each switchover to thwart shared RAM leakages. All data buffers are actively cleared once they have been used.
  • Automatic switching (configuration option)
    • Free-flow KVM and audio control between ports without the need to press any buttons. Simply move the mouse between windows.
  • Hardware anti-tampering
    • Holographic anti-tampering labels protect the product's enclosure, providing a clear visual indication if it has been opened or compromised.
  • Non-reprogrammable firmware
    • There is no access to the product's firmware or memory through any port. Firmware is permanently stored in non-reprogrammable Read Only Memory (ROM) to prevent modification. Firmware integrity is verified through a self-test procedure during power up. Detection of a critical failure disables the device and provides a clear visual indication to the user.
  • Restricted USB function
    • The USB ports will only accept HID (Human Interface Devices), such as keyboards and mice. Other devices, such as USB storage drives, are actively prohibited.
  • Video Performance
    • Up to UHD 4K video resolution at 60 fps for graphics intensive applications requiring very high quality.
  • Audio hold
    • Assign the audio port to a specific computer while switching the KVM to other computers. Useful when a user needs to listen to audio from one computer, whilst working on another.
