DK82DU-3 is a secure dual head 8-port, 4K30 UHD DVI-I KVM switch. It enables users to share peripherals - keyboard, video, mouse, audio, and USB - between eight 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. DK82DU-3 provides the highest possible isolation between connected computers and is NIAP Common Criteria Protection Profile version 3.0 (PP3.0) certified.
