Belkin Universal 2nd Gen Secure KVM Switch – 4-Port Single Head without CAC

Product Overview

The Belkin Universal 2nd Gen Secure KVM Switch (F1DN104KVM-UNN4) is a 4-port, single-monitor NIAP PP4.0-certified secure KVM switch for government, military, and enterprise IT environments requiring validated air-gap isolation between classified network security enclaves. This TAA-compliant secure KVM delivers the complete Universal 2nd Gen security architecture — optical data diodes, embedded peripheral emulation, and 8th-order elliptical audio filtering — in a single-head, no-CAC configuration, making it the cost-effective choice when smart card authentication is handled separately and a single operator display is sufficient. It is fully compatible with the optional Belkin KVM Remote Control with Integrated Keyboard and Belkin mounting accessories.

Product Description

The F1DN104KVM-UNN4 addresses government and enterprise multi-domain workstation requirements where operators need access to up to four classified or sensitive security domains through a single set of peripherals, and where DoD CAC authentication is managed at the endpoint or through a separate authentication system. Optical data diodes on all four input channels physically enforce unidirectional data flow between connected computers, providing hardware-layer air-gap isolation that cannot be bypassed by software configuration or user error. Embedded peripheral emulation ensures continuous keyboard and mouse activity emulation on all inactive ports, closing the timing-based side-channel attack window.

DisplayPort/HDMI combo connectors with built-in auto-sensing and internal video conversion eliminate the need for external DP-to-DVI or HDMI-to-DVI adapters, allowing the same KVM to serve systems with DisplayPort, HDMI, or DVI video outputs at up to 4K UHD (3840x2160) at 60Hz. The 8th-order elliptical audio filter protects against ultrasonic data exfiltration through audio channels, an attack vector that is specifically addressed in SCIF and sensitive compartmented information facility security policies. Six USB ports support keyboard, mouse, and additional USB peripheral connections at the operator console.

The configurable front panel enclave color coding aligns with the optional Belkin KVM Remote Control with Integrated Keyboard, providing operators with clear visual classification-level awareness. The F1DN104KVM-UNN4 is US-manufactured and fully TAA compliant, supporting desktop and under-table installation configurations. Always-on active anti-tamper protection maintains physical security integrity with automatic lockdown on intrusion detection.

Key Features

• Active Anti-Tamper, Always On - Continuous physical tamper detection with automatic lockdown on intrusion event.
• Configurable Enclave Color Coding - Front panel and optional remote keyboard per-channel LED color coding supports operator classification awareness.
• TAA Compliant, US-Manufactured - Eligible for GSA Schedule and government contract procurement; manufactured in the United States.
• Flexible Mounting - Desktop and under-table installation with optional Belkin mounting accessories.

Typical Applications

• Government and DoD workstations with single-monitor four-domain access where CAC authentication is managed at the endpoint
• SCIF and secure facility operator stations requiring NIAP PP4.0-certified single-head KVM switching
• Federal agency IT procurement programs standardizing on TAA-compliant NIAP-certified secure KVMs
• Defense contractor desktops in secure environments with up to four network domain switching requirements
• Military and intelligence workstations where cost-effective NIAP compliance is required without per-port CAC integration

Technical Specifications

Frequently Asked Questions

Is the F1DN104KVM-UNN4 NIAP PP4.0 certified?

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

Why would I choose this over the CAC-equipped version?

The F1DN104KVM-UNN4 is appropriate when DoD or smart card authentication is handled at the endpoint computer or by a separate authentication solution, and integrated per-port CAC readers are not required by the security policy. It is typically a lower-cost option when CAC integration is unnecessary.

Is it TAA compliant?

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

What video formats are supported?

DisplayPort/HDMI combo connectors with internal DVI conversion support DisplayPort, HDMI, and DVI sources at up to 4K UHD (3840x2160) at 60Hz without external adapters.

Can I add an external USB CAC reader?

Yes. External USB smart card readers can be connected through the KVM's available USB ports on the operator console side, if CAC authentication is needed after purchase.

What mounting options are available?

The unit supports desktop and under-table installation. Optional Belkin mounting accessories are available for each configuration.

What anti-tamper measures are included?

Always-on active anti-tamper monitoring with automatic protective lockdown on physical intrusion detection.

What warranty is included?

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