Kramer DK42HU-3 (22-00003720)

Kramer's HighSecLabs DK42HU-3 is a secure dual head 4-port, 4K30 UHD HDMI KVM switch. It enables users to share peripherals - keyboard, video, mouse, audio, and USB - between four different security-level networks/computers while isolating all hosts and protecting against data leakage and malicious attacks through shared peripherals. It also enables assigning a USB port to a specific computer while switching other peripherals, such as when a USB smart card reader must remain mapped to a certain computer. DK42HU-3 provides the highest possible isolation between connected computers and is NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certified.

  • Highest Security by Design — NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certification for peripheral Sharing Switch (PSS) devices.
  • 4K30 UHD Resolution — Supports resolutions up to 3840×2160 @30Hz.
  • Work Freely Without Compromising Security — Display and control classified and non–classified computers without compromising security.
  • Prevent Information Leaks — Block peripheral exploits, information leaks, eavesdropping, signal transmission, computer malware, hardware and firmware tampering.
  • Filter USB Peripherals — Allow or block specific USB devices based on VID/PID characteristics.
  • Dual Display — Provides flexible presentation options with duplicate or extend view modes.
  • Smooth Switching Between Computers (Virtual Display Technology) — Automatically switch all peripheral control from one computer to another by dragging the cursor between each computer's display border.
  • Biometric/Smart–Card Reader Support — Connect a smartcard/biometric reader to the secure port to support user authentication across multiple isolated computers.
  • Keyboard Lock Indication — Caps Lock, Num Lock, and Scroll Lock indication on front panel.
  • Versatile and Flexible — Configurable as a KVM switch (default) for sharing a display, keyboard and mouse between connected computers, or KM switch for sharing keyboard and mouse and simultaneously working on multiple computers connected to separate displays.
