Secure 4-Port KVM for Government Work
The Belkin F1DN204KVM-UN-4 is a dual-head KVM switch built for NIAP Protection Profile PSD 4.0 compliance. It manages up to four host computers across two displays for the user. Dedicated processors with emulators on every port isolate video, audio and peripheral paths. Unidirectional optical data diodes prevent peripherals from becoming breach vectors.
Sustained Isolation Under Continuous Switching
Each port runs its own processor and emulator, so isolation does not degrade when operators cycle through targets repeatedly. Optical diodes enforce one-way data flow at all times, removing the risk of cumulative leakage during long shifts. The protected display interface maintains monitor security without reset cycles. CAC and audio freeze functions hold sensitive channels steady across extended sessions.
Verify Port Count and Mounting Before Ordering
Confirm that four host connections and two display outputs match your workstation layout. Check whether the extrusion form factor fits your rack or under-counter space without extra brackets. Ensure your cables match the TAA combo and video specifications required for deployment. The optional remote control with integrated keyboard adds front-panel colour coding if your workflow demands it.

Questions about this item
Does the Belkin F1DN204KVM-UN-4 generate noticeable heat or fan noise during continuous daily operation?
The unit uses passive cooling with no internal fans, so it runs silently and produces minimal heat even when switching between four connected computers all day.
Which cables must I already have to connect two monitors and four computers to this KVM switch?
You need four TAA-compliant combo cables that carry both video and USB signals, plus two display cables matching your monitor inputs for the dual-head output.
Will my older 1080p monitors work correctly with the 4K-capable video ports on this switch?
Yes, the combo connectors support resolutions up to 3840x2160 at 60 Hz and will downscale automatically to 1080p or other lower resolutions without configuration.
