The K524E 4-Port DisplayPort KVM Switch from Kramer allows users to share peripherals like keyboard, mouse, and monitor between 4 different security-level networks/computers. It supports 4 computers connected to four displays. An RDC port allows for user-friendly, comfortable remote control of the KVM switch. Fully compatible with EAL4+ and NIAP security requirements, the switch is suitable for use by agencies, military and financial institutions, and any other organization that handles sensitive and confidential information.
Security is further leveraged by the inclusion of a USB user authentication port (DPP) that allows you to connect a Biometric or Smart Card Reader. This requires insertion of a physical authentication card or identification of a fingerprint to access the various computers/networks.
