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) 
Switch channels (KVM plus audio) simply by moving the mouse across the screen border, whilst pressing the Ctrl key.

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.
