Kramer Electronics K404F Black KVM switch

4-Port DVI−D KVM Combiner The K404F is a secure 4−port DVI−D KVM combiner that allows secure, simultaneous work and interaction with up to four computers. It is an essential tool for heavy−duty users challenged by frequent switching between isolated networks. The K404F integrates up to four isolated sources at different security levels into a single combined display. 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.
