You've got eight machines on one desk and one operator who can't afford a single data leak between them. This is the switch that keeps those paths locked down — dedicated processors per port, optical data diodes, and CAC freeze so nothing crosses where it shouldn't.
The Belkin F1DN108KVM-UN-4 handles eight host computers on a single 4K monitor at 60Hz. USB keyboard and mouse switch with no lag. Audio runs over a 3.5mm jack with ultrasonic filtering to stop bleed-through. Port naming and colour-coding are customisable, so your team stops hitting the wrong machine at 2am.
Built for NIAP Protection Profile PSD 4.0 compliance and TAA. Extruded aluminium housing, rack-mount or under-counter. Tamper-evident packaging and holographic labelling mean you can verify integrity out of the box.
In the box: the switch, a 12V 2.5A universal power supply with worldwide adaptors, port naming labels, rack-mount adaptors, quick start guide, and compliance documentation
