Secure KVM for defence and intelligence

The ATEN CS1142DP4 is a 2-port Dual Display KVM switch certified to PSD PP v4.0 by NIAP. It isolates two computers of different security classifications while sharing one keyboard, mouse, dual monitors and speaker set. Unidirectional data flow and strict peripheral filtering prevent unauthorised data leakage between connected sources.

Suited for classified environments

This switch serves operators who must control multiple systems from a single console without crossing security domains. It is not for buyers who need multi-user access or who require switching beyond two computer ports. Facilities without NIAP PSD PP v4.0 mandates may find the security feature set exceeds their requirements.

Dual 4K 60 Hz over DisplayPort

Each of the two computers connects through three DisplayPort inputs, delivering 3840 x 2160 at 50 or 60 Hz to the shared displays. The six DisplayPort ports and four USB ports define the total peripheral and video connectivity available for the secure desktop installation.

Questions about this item

What does 3840 x 2160 at 50 Hz and 60 Hz mean when the switch is connected to two computers?

Each connected computer can drive a dual DisplayPort setup at 3840 x 2160 resolution, with the switch passing 50 Hz or 60 Hz refresh rates to both monitors without scaling or compression.

How does PSD PP v 4.0 compliance limit the data paths through the six DisplayPort and four USB ports?

The certification enforces unidirectional video flow from each computer to the displays, isolates USB HID traffic to keyboard and mouse only, and blocks all other peripheral classes so no data can leak between the two connected systems.

What physical space and mounting does the desktop unit need for a dual-display, two-computer installation?

The desktop chassis requires a flat surface with room for six DisplayPort cables, four USB cables and two power cords; no rack ears or brackets are included, so allow clearance for cable bend radius behind the unit.
