Kramer Electronics The secure 4-port DVI-D KVM combiner 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 KVM combiner 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.

This KVM combiner works constantly and monitors multiple channels, no channel switching required for heavy-duty user convenience. You can view up to four simultaneous networks in real-time through a pixel-by-pixel video image; no quality loss, latency, reduced colors, dropped frames or artifacts because of the device's advanced viewing technology. The advanced scaling function allows the user scaling of the video source by 1/2 and by 1/4 to assure an optimized monitoring and working experience.
