Kramer HighSecLabs Secure 2x4 4K30 UHD DVI-I Mini-Matrix KVM Switch with fUSB

Discover a pinnacle in secure, multi-host control with the SX42DU-3 from Kramer HighSecLabs. This compact 2x4 4K30 UHD DVI-I mini-matrix KVM switch is engineered for environments where separate security classifications must coexist without compromising access or performance. View, control, and share peripherals—keyboard, video, mouse, audio, and USB devices—across four computers in a single, streamlined console. With fUSB support and strategic port allocation, you gain precise, reliable control over your trusted systems while maintaining robust data separation and secure operation.

• Secure 2x4 matrix design: manage four different computers with varying security classifications from one console, enabling simultaneous monitoring and control without cross-contamination of data.
• 4K30 UHD DVI-I video support: enjoy crisp, high-resolution video at 3840x2160 resolution (30 Hz) across compatible displays, ensuring clear visuals for diagnostic, monitoring, or productivity tasks.
• Efficient peripheral sharing: securely share keyboard, mouse, audio, and USB devices between hosts while preserving strict isolation between systems, reducing desk clutter and improving workflow efficiency.
• fUSB port assignment: flexible USB device allocation lets you pin specific USB peripherals to particular hosts, enhancing security and reducing the risk of unintended cross-host access.
• Compact, secure form factor: a space-saving mini-matrix design that fits neatly in secure control rooms, labs, and network operation centers without sacrificing performance or reliability.
