ADDERView® 4K Single-head (DP/HDMI) 4-port secure KVM switch

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

ADDERView® Secure switches enable a KVM plus audio desktop to be shared between different classification level computers. Designed for superior usability, the switches feature configurable LED buttons and a real-time status display.

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 (Config 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.

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.

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.

Uni-Directional Audio
Enforces computer-to-speaker, one-way flow of sound through uni-directional optical data diodes. Prevents eavesdropping and line-in re-tasking by blocking speaker-to-computer communication.
