Secure KVM matrix for two operators

The Black Box SS4PDVI4X2UCAC is a secure KVM matrix switch that lets two operators control up to eight DVI computers from a single console. It is built for environments where data isolation between ports and the outside network is mandatory. NIAP 3.0 certification confirms the design meets strict government-grade security requirements.

NIAP 3.0 certified isolation

Each channel uses mechanical, electrical and optical isolation to prevent data leakage between secure ports. Uni-directional data flow from computer to peripheral blocks eavesdropping through vulnerable devices. Protected firmware, secure EDID learning, keyboard cache wiping and chassis intrusion protection add further defence layers.

Passive cooling with no fan noise

The unit operates without active cooling, so it adds no audible noise to a secure workspace. Power is drawn from the connected systems through the DVI and USB links, eliminating the need for an external power supply. This keeps the deployment simple and the thermal footprint negligible.

Questions about this item

What does the NIAP 3.0 certification mean when the switch is installed in a secure facility?

NIAP 3.0 certification confirms the switch meets strict government security requirements, including isolated channels, uni-directional data flow, protected firmware, and chassis intrusion protection to prevent data leaks between connected computers.

How does the DVI interface limit the video signals I can run through this matrix?

The DVI ports carry digital video only, so each connected computer must output a DVI-compatible signal; analog VGA or newer DisplayPort and HDMI sources would require active converters not included with the switch.

What physical space and power does the 4 x 2 matrix unit need to be rack-mounted?

The unit is designed for rack installation and includes an external AC power adapter; it occupies a standard rack width and depth for secure KVM matrix switches of this port count.
