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

Product Overview

The Belkin Universal 2nd Gen Secure KVM Switch (F1DN204KVM-UNN4) is a 4-port, dual-monitor NIAP PP4.0-certified secure KVM switch for government, military, and enterprise IT environments that require validated isolation between multiple classified or sensitive network security enclaves. This TAA-compliant secure KVM provides all the security capabilities of the Universal 2nd Gen platform — including optical data diodes, embedded peripheral emulation, and 8th-order elliptical audio filtering — in a dual-head configuration without an integrated CAC reader, suited to deployments where smart card authentication is handled at the endpoint or by a separate authentication device.

Product Description

The F1DN204KVM-UNN4 targets secure environments where four-domain operator access and dual-monitor productivity are required, but Common Access Card authentication is either not mandated or managed separately. Optical data diodes enforce strict air-gap isolation at the hardware level on all four channels, preventing data leakage between connected computers regardless of software activity. Embedded peripheral emulation maintains keyboard and mouse emulation on all inactive channels continuously, eliminating timing-based side-channel exploits that target peripheral interfaces.

The dual-head output simultaneously drives two independent monitors per operator, enabling side-by-side display of output from a single selected security domain while maintaining clear visual separation from other connected domains. DisplayPort/HDMI combo connectors with internal auto-sensing conversion allow the KVM to interface with DisplayPort, HDMI, and DVI video sources at up to 4K UHD (3840x2160) at 60Hz per display, without external video conversion hardware. The 8th-order elliptical audio filter protects the audio path against ultrasonic attack vectors.

The configurable front panel enclave color coding aligns with the optional Belkin KVM Remote Control with Integrated Keyboard for visual classification-level awareness. US-manufactured and TAA compliant, the F1DN204KVM-UNN4 supports desktop and under-table mounting configurations and features always-on active anti-tamper protection with automatic lockdown on physical intrusion detection. Input voltage acceptance of 120V-230V AC supports both domestic and international deployment.

Key Features

• NIAP PP4.0 Certified - Common Criteria validated to NIAP Protection Profile for Peripheral Switching Devices v4.0; satisfies current federal and DoD KVM security mandates.
• 4-Port, Dual-Monitor Configuration - Connects up to four computers with two simultaneous video outputs for dual-display operator workstations.
• No Integrated CAC Reader - Suited for environments where DoD CAC/smart card authentication is handled at the endpoint device or via a separate authentication solution.
• Optical Data Diodes per Channel - Hardware-enforced one-way data paths on all four channels prevent cross-domain data leakage at the physical layer.
• Embedded Peripheral Emulation - Constant keyboard and mouse emulation on inactive channels neutralizes timing-based side-channel attacks.
• 8th-Order Elliptical Audio Filter - Protects audio channels against ultrasonic data exfiltration in SCIF and secure facility deployments.
• Universal Video Combo Connectors - DisplayPort/HDMI combo inputs with internal DVI conversion support major video standards at up to 4K/60Hz per head — no adapters required.
• Active Anti-Tamper, Always On - Continuous tamper monitoring with automatic lockdown on detection of physical intrusion.
• Configurable Enclave Color Coding - Per-channel LED color coding on front panel and optional remote keyboard reduces classification-level operator errors.
• TAA Compliant, US-Manufactured - Qualifies for GSA Schedule and government contract procurement; made in the United States.
• Universal AC Input - Accepts 120V-230V AC for domestic and international facility deployments.

Typical Applications

• Government and DoD workstations with four-domain dual-monitor access where CAC authentication is managed separately
• Secure facility and SCIF operator stations requiring NIAP PP4.0-certified KVM switching
• Defense contractor and federal agency desktops standardizing on TAA-compliant NIAP secure KVM infrastructure
• Enterprise multi-level security environments with dual-monitor operator workstations
• Military and intelligence environments where endpoint-level smart card authentication replaces per-port CAC readers

Technical Specifications

Frequently Asked Questions

Why choose the no-CAC version over the CAC-equipped model?

The F1DN204KVM-UNN4 is appropriate when smart card or CAC authentication is handled by the endpoint computer or a separate authentication server, and a per-port integrated reader is not required by the facility's security policy. It carries the same NIAP PP4.0 certification and all other security protections.

Is this product NIAP PP4.0 certified?

Yes. Common Criteria certified to NIAP Protection Profile for Peripheral Switching Devices version 4.0, meeting current federal and DoD security procurement requirements.

Is the F1DN204KVM-UNN4 TAA compliant?

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

What video interfaces are supported?

DisplayPort and HDMI combo connectors with internal DVI conversion support all major video standards at up to 4K UHD (3840x2160) at 60Hz per display head — no external converters needed.

How does the dual-head feature work with four ports?

Each of the four input ports connects to a separate computer. When an operator selects a channel, both monitor outputs switch to that computer simultaneously, providing a dual-display view from a single selected system.

Can external USB CAC readers be used with this KVM?

Yes. While there is no integrated per-port CAC reader, external USB smart card readers can be connected via the available USB ports on the operator console side.

What physical security features are included?

The unit features always-on active anti-tamper detection with automatic lockdown on physical intrusion detection.

What is the warranty?

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