Belkin’s Secure DisplayPort KVM Switch offers superior data security and protection by providing true air-gap network isolation between systems and networks while improving operator efficiency and effectiveness in working across security domains. The KVMs are fully certified to the NIAP Protection Profile version 3.0 standard and secured from the point of production through shipment and delivery, making them ideal for use in desktop information security applications within the intelligence community, military and other government agencies, and all applications where absolute isolation of network assets is considered critical. The DisplayPort 1.2 compliant inputs and HDMI outputs support brilliant UHD 4K resolution (3840×2160) video at 30Hz or 2560×1600 at 60Hz. The integrated Common Access Card port allows a single CAC or PIV card reader to be used to provide CAC card credentials to all four client machines. The keyboard and mouse ports provide uni-directional data paths, filtered for HID communication only, thus greatly reducing the chances of information theft and blocking the use of unauthorized USB peripherals. The F1DN104W-3 supports up to four computers and provides the ability to switch CAC, keyboard, mouse, and uni-directional audio output onto two HDMI monitors, thus greatly reducing the clutter on an operator’s desk.
