The Belkin F1DN104E Advanced Secure DVI-I KVM Switch offers superior security and data protection for government agencies by providing true data path isolation between systems and networks. The Belkin Secure KVM is fully compatible with legacy and new government systems and exceeds NIAP security requirements. Using uni-directional data paths with optical diodes, the F1DN104E prevents peripherals from being used to leak information from one computer system to another. Additional security is provided through the F1DN104E Advanced Secure end-to-end tamper-proof system that prevents physical tampering, and its intuitive user interface reduces user-switching errors by providing clear identification. The Belkin F1DN104E model supports two monitors and up to four computers.

  • Supports 2 monitors and up to 4 computers
  • Dedicated processors with emulators for every port: Isolated port paths for video, audio, peripherals, and smart card readers prevent data leaks between computers
  • Unidirectional data paths: Optical data diodes prevent peripherals from being used to breach systems
  • Display security: Protected display interface prevents data leakage via the monitor
  • Peripheral management: USB device detection prevents unauthorized peripheral usage

Question: Will this KVM switch support or work with a DVI to Display Port (DP) adapter between the switch and PC?
Answer: Thank you for your inquiry,

Absolutely, please see our Video Adapters & Converters page for DVI to DisplayPort adapters.

Some users have reported issues with adapting HDMI to DP, but that is the only conversion issue with DP that I am aware of.
