SC42DHU−3 is a secure 4−port 4K30 UHD DVI−I to HDMI KVM combiner. It enables users to share peripherals – keyboard, video, mouse, audio and USB − between two 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. Advanced multiviewer and scaling capabilities enable increased productivity in environments that require viewing and interacting with many computers simultaneously. SC42DHU−3 provides the highest possible isolation between connected computers and is designed to meet the security requirements of government agencies, military, financial institutions, and similar security−sensitive customers.
