Kramer Electronics The K424F is a secure 4-port dual display 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 K424F integrates up to four isolated sources at different security levels into two large displays.

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.
