Belkin Universal 2nd Gen Secure KVM Switch – 4-Port Single Head with CAC Reader

Product Overview

The Belkin Universal 2nd Gen Secure KVM Switch (F1DN104KVM-UN-4) is a 4-port, single-monitor secure KVM switch certified to NIAP Protection Profile for Peripheral Switching Devices version 4.0, built for government, military, and enterprise IT environments requiring validated cross-domain isolation. This TAA-compliant secure KVM includes an integrated Common Access Card (CAC) reader per port for DoD-standard smart card authentication, and its single-head output makes it the efficient choice for four-domain operator stations where a single display is the standard workstation configuration. It delivers the full Universal 2nd Gen security platform in a compact, cost-effective form factor.

Product Description

The F1DN104KVM-UN-4 is designed for government and enterprise analyst workstations where operators must access up to four classified or sensitive network security enclaves from a single keyboard, mouse, and display without exposing inter-domain data leakage paths. Optical data diodes on all four channels enforce hardware-level unidirectional isolation between connected computers, providing physical air-gap separation that is independent of software configuration. Embedded peripheral emulation maintains continuous keyboard and mouse emulation on all inactive channels, preventing timing-based side-channel exploits.

The built-in CAC reader per input port provides integrated DoD PIV and smart card authentication at each connected workstation, eliminating external card reader hardware from the operator desktop and simplifying procurement. The 8th-order elliptical audio filter protects audio interfaces against ultrasonic data exfiltration. DisplayPort/HDMI combo connectors with internal auto-sensing conversion support DisplayPort, HDMI, and DVI video sources at up to 4K (3840x2160) at 60Hz, providing universal video compatibility across modern and legacy systems without external converters.

Configurable enclave color coding on the front panel maps to the optional Belkin KVM Remote Control with Integrated Keyboard, reducing classification-level operator errors in multi-domain environments. The F1DN104KVM-UN-4 is US-manufactured and fully TAA compliant, supports desktop and under-table deployment, and maintains always-on active anti-tamper protection throughout its service life.

Technical Specifications

Frequently Asked Questions

Is the F1DN104KVM-UN-4 NIAP PP4.0 certified?

Yes. This unit is Common Criteria certified to NIAP Protection Profile for Peripheral Switching Devices version 4.0, satisfying current federal and DoD security requirements for multi-domain KVM switches.

Does it include CAC readers?

Yes. An integrated Common Access Card reader is included on each of the four input ports, enabling DoD PIV smart card login without external USB card readers on the desktop.

How does this compare to the dual-head 4-port model?

The F1DN104KVM-UN-4 supports a single monitor output per operator. The dual-head model (F1DN204KVM-UN-4) drives two independent monitors simultaneously. Both support four ports, NIAP PP4.0 certification, and integrated CAC readers.

Is this product TAA compliant?

Yes. US-manufactured and fully TAA compliant, qualifying for GSA Schedule and government procurement vehicles.

What video standards are supported?

DisplayPort/HDMI combo connectors with internal DVI conversion support all major video standards at up to 4K UHD (3840x2160) at 60Hz without external adapters.

Can external USB devices be connected through the KVM?

Yes. The unit provides 11 USB ports on the operator console side for keyboard, mouse, CAC reader, and additional USB peripheral connections.

What anti-tamper protections are built in?

Always-on active anti-tamper detection continuously monitors for physical intrusion and triggers an automatic lockdown if tampering is detected.

What warranty is included?

A 1-year limited warranty with US-based complimentary technical support from Belkin.
