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

Product Overview

The Belkin Universal 2nd Gen Secure KVM Switch (F1DN204KVM-UN-4) is a 4-port, dual-monitor secure KVM switch certified to NIAP Protection Profile for Peripheral Switching Devices version 4.0, designed for government, military, and enterprise IT environments requiring Common Criteria-validated isolation between classified or sensitive network security enclaves. This TAA-compliant secure KVM includes an integrated Common Access Card (CAC) reader per port for DoD-standard smart card authentication, and its dual-head video output allows a single operator to simultaneously monitor two independent displays across up to four connected computers. It is the standard-configuration choice for four-domain workstations where dual-monitor productivity and classified network isolation are both required.

Product Description

The F1DN204KVM-UN-4 is purpose-built for analyst, operator, and engineer workstations in environments where DoD and federal IT security policy mandates physical isolation between network security enclaves. Optical data diodes on each of the four channels maintain strict air-gap isolation at the hardware level, preventing data leakage between connected computers regardless of software activity. Embedded peripheral emulation keeps keyboard and mouse active on all inactive channels, neutralizing timing-based side-channel attack vectors.

The dual-head configuration drives two independent monitors simultaneously, enabling operators to display output from different security domains side by side — a standard requirement in intelligence and command environments. DisplayPort/HDMI combo connectors with internal auto-sensing conversion eliminate external video adapters, supporting DisplayPort, HDMI, and DVI sources at up to 4K (3840x2160) resolution at 60Hz per display. USB ports (11 total) support keyboard, mouse, CAC readers, and additional USB peripherals across the operator station. The 8th-order elliptical audio filter protects against ultrasonic attack vectors through audio channels.

The front panel features configurable enclave color coding that mirrors the optional Belkin KVM Remote Control with Integrated Keyboard, reducing classification-level operator errors in multi-domain environments. US-manufactured and TAA compliant, the F1DN204KVM-UN-4 supports desktop and under-table installation. Active anti-tamper protection is always on, with automatic lockdown on detection of physical intrusion.

Technical Specifications

Frequently Asked Questions

Is the F1DN204KVM-UN-4 NIAP PP4.0 certified?

Yes. This secure KVM switch is Common Criteria certified to NIAP Protection Profile for Peripheral Switching Devices version 4.0, meeting the current standard for U.S. government and DoD multi-domain KVM deployments.

Does it include a CAC reader?

Yes. An integrated Common Access Card reader is built into each of the four input ports, supporting DoD PIV smart card authentication without external card reader hardware.

What is the difference between the CAC and no-CAC versions?

The F1DN204KVM-UN-4 (with CAC) includes integrated smart card readers per port for environments requiring DoD CAC authentication. The no-CAC variant (F1DN204KVM-UNN4) omits the card readers and is suited for environments where smart card authentication is handled separately or not required.

Is this product TAA compliant?

Yes. US-manufactured and fully TAA compliant, making it eligible for GSA Schedule and government procurement contracts.

What video resolutions and formats are supported?

The combo connectors support DisplayPort and HDMI inputs with internal DVI conversion, at up to 4K UHD (3840x2160) at 60Hz per display head, with no external converters required.

How does the dual-head configuration work?

The dual-head design provides two independent video outputs to two monitors simultaneously. When an operator switches channels, both displays switch together, allowing side-by-side viewing of two monitors for a single selected computer or security domain.

What anti-tamper measures are included?

The always-on active anti-tamper system continuously monitors for physical intrusion attempts and initiates an automatic protective lockdown if tampering is detected.

What warranty does this product carry?

A 1-year limited warranty is included. Belkin provides complimentary US-based technical support.
