Secure KVM Switch for Sensitive Environments

The Black Box KVS4-2004VX is a NIAP Protection Profile 4.0 certified secure KVM switch designed for defence, government and financial networks. It allows one or two operators to control up to four isolated computers using dual-monitor DisplayPort video. Mechanical, electrical and optical signal isolation prevents data leakage between connected systems.

Verify DisplayPort Outputs and USB 1.1 Peripherals

Each target computer must provide two DisplayPort outputs and a USB Type-B port for the switch inputs. The console side requires two DisplayPort monitors and USB 1.1 keyboard and mouse devices connected to the dedicated Type-A ports. Audio switching uses 3.5 mm stereo connectors on both input and output sides. Cables up to 20 ft are supported for both input and output video runs.

Passive Cooling Within 0 to 40 °C Operating Range

The unit operates without internal fans, drawing power from an external 12 V DC 3 A adapter with centre-pin positive polarity. Operating temperature spans 32 °F to 104 °F (0 °C to 40 °C) with humidity up to 80 % RH non-condensing. The metal chassis measures 12.57" W x 1.76" H x 6.69" D and weighs 4.2 lb, dissipating heat passively in rack or desktop installations.

Questions about this item

What cables are included with the KVS4-2004VX and what must be purchased separately?

The switch ships with an external 12 V DC 3 A power adapter; the eight DisplayPort input cables, eight USB Type-B input cables, two DisplayPort output cables and two USB Type-A console cables are not included and must be bought separately.

How do I choose between the single-monitor and dual-monitor DisplayPort configurations of this Secure KVM Switch?

The KVS4-2004VX is the 4-port dual-monitor model providing two DisplayPort outputs for two 3840 x 2160 @ 30 Hz displays; select it when you need two monitors, otherwise choose the single-monitor variant in the same series.

What does the 3840 x 2160 @ 30 Hz headline resolution mean once the switch is installed in a real system?

Each connected computer can drive up to 3840 x 2160 at 30 Hz per DisplayPort output through the switch, so two 4 K monitors run at that resolution and refresh rate simultaneously without signal degradation over cable runs up to 20 ft.
