Two machines at different security classifications sitting on one desk, and you need to switch between them without a single byte crossing the boundary. The ATEN CS1142H4 handles exactly that.
It's a 2-port USB HDMI dual display KVM switch certified to PSD PP v4.0 by NIAP – the standard defence and intelligence installations actually require. Share one keyboard, mouse, monitor, and speaker set across both sources. Switching is manual only: front panel pushbuttons or a Remote Port Selector (RPS 1, sold separately). No software layer, no network path, no accidental cross-talk.
Data flow is unidirectional. Audio is strictly filtered. Device connectivity is restricted and configurable. The tamper-proof design stays always-on, so the isolation isn't something you have to remember to enable.
Built for government, military, healthcare, banking, and any environment where what's on one side must never see the other. Package includes a power cord and user instructions. RPS is a separate purchase if you need it.
