Black Box Secure NIAP 4.0 KVM MultiViewer 4-Port DisplayPort CAC KVS48004VPX

SKU CH-NGEA-6V8VS

A secure NIAP 4.0 KVM MultiViewer displaying four DisplayPort computers on one monitor with isolated channels and CAC support

  • NIAP 4.0 certification meets strict government security standards
  • Four DisplayPort sources shown simultaneously on one monitor
  • Isolated channels prevent data leakage between secure ports
  • Uni-directional peripheral flow blocks eavesdropping attempts
  • Protected firmware stops unauthorised reprogramming or reading

Secure NIAP 4.0 KVM for defense analysts

The Black Box Secure NIAP 4.0 KVM MultiViewer connects four DisplayPort computers to one monitor and a single keyboard and mouse set. It is built for operators in defense or intelligence who must view and control sources at different security levels simultaneously. The switch provides isolated channels to prevent data leakage between secure ports and the outside world.

Mechanical electrical and optical isolation

Uni-directional data flow moves from computer to peripheral to block eavesdropping through vulnerable devices. Protected firmware stops intruders from reprogramming or reading the device firmware. Secure EDID learning prevents unsecure data transmission through DDC lines during normal operation.

CAC support and multi-view modes included

The unit supports Common Access Card readers for authenticated access on secure networks. Operators can select Quad-View, T-Quad or picture-in-picture layouts to display all four sources in real time on a single screen without additional software installation.

Questions about this item

How do I install the KVS48004VPX and what step is commonly missed?

Connect each of the four DisplayPort sources to the isolated input ports, attach one monitor to the output, then plug in the shared keyboard and mouse; the step often missed is allowing the unit to complete secure EDID learning before switching sources.

What maintenance or replacement will the KVS48004VPX need over time?

The protected firmware is sealed against reprogramming, so no firmware updates are required; only the external power supply or cables may need replacement if they show physical wear.

What limit appears first when the KVS48004VPX runs continuously under heavy load?

The uni-directional data-flow design and mechanical, electrical, and optical isolation cap sustained throughput at the DisplayPort link rate of each isolated channel, so video bandwidth per port becomes the first bottleneck.
