The K2016E is a large 16−port, DVI−I secure KVM switch. It allows users to share peripherals – keyboard, mouse and monitor – between sixteen different security−level networks/computers. The K2016E is especially designed to provide the highest possible isolation between sixteen connected computers with each computer connected to a single display. The video ports support various video interfaces, from VGA to dual−link DVI and HDMI. An RDC port enables user−friendly, comfortable remote control of the KVM switch. For enhanced security, a USB user authentication port (DPP) connects to a smart card or biometric reader. This requires the insertion of a physical authentication card or identification of a fingerprint to access the various computers/networks.
