The Kramer K524E 20-0001890 is a secure 4−port DisplayPort dual−display KVM switch. It allows users to share peripherals – keyboard, mouse and monitor – between four different security−level networks/computers. It provides the highest possible isolation between four connected computers operating in a dual display mode. 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.
