K244E Secure KVM Switch: 4-Port, DVI-I, Dual-Display Support.

How to Order

The K244E is a secure 4-port, DVI-I dual-head KVM Switch.

It is especially designed to provide the highest possible isolation between four connected computers with each computer hav‌ing two video output ports. The video ports support various video interfaces, from VGA to dual-link DVI and HDMI. Each computer may connect to up to two independent displays and operate in a dual-display mode.

K244E is equipped with an RDC port enabling user-friendly, comfortable remote control of the KVM switch.

Security is further leveraged by the inclusion of a USB user authentication port (DPP) that enables connecting a Biometric or Smart Card Reader, requiring the insertion of a physical authentication card or identification of a fingerprint to access the various computers/networks.

The K244E meets the requirements of companies challenged by the need to provide both secret and top-secret network access together with unclassified or Internet access.

It is a perfect fit for high-security organizations such as government agencies, military and financial institutions, and any other organization that handles sensitive and confidential information.
