Secure 4-port KVM for multi-level environments
The Belkin F1DN104U is a 4-port USB KVM switch validated to NIAP Common Criteria EAL 4. It lets one operator control four separate computers from a single keyboard, mouse and monitor while keeping each system isolated at different security levels. Non-reprogrammable firmware and the absence of hot keys or OSD prevent data from being stored on the switch itself.
Replaces basic desktop KVMs needing certified
Standard KVM switches lack the security certification and tamper-resistant design required for environments handling classified or sensitive data. The jump is worth it when procurement mandates NIAP validation or when switching between networks of differing classification without risk of cross-domain data leakage. Rugged metal construction also suits 1U rack or desktop placement.
Limited to VGA video at 1920x1440 75Hz
The single monitor port uses a D-Sub connector, restricting output to analogue VGA signals up to 1920x1440 at 75Hz. Digital interfaces such as DVI, HDMI or DisplayPort are not supported, so modern displays require an active adapter. USB peripheral switching is confined to keyboard and mouse; other USB devices cannot be shared through the switch.

Questions about this item
What video connector type does the Belkin F1DN104U use for its single monitor port?
The switch uses a D-Sub (VGA) connector for its single monitor connection, supporting resolutions up to 1920 x 1440 at 75Hz.
How do you switch between the four connected computers on this KVM, and what common mistake should be avoided?
Switch using the front-panel push buttons; there are no hotkeys or OSD menus, so pressing keyboard combinations will not change the active port.
Does the Belkin F1DN104U require any firmware updates or battery replacements during its service life?
The firmware is non-reprogrammable by design to prevent tampering, so no updates are needed, and the unit has no internal battery to replace.
