How to Order

The K204 is a secure 4-port, DVI-I KVM Switch.

It allows users to share peripherals - keyboard, mouse and monitor - between four different security-level networks/computers.

K204 supports four isolated computers each hav‌ing DVI-I video output. In addition to supporting DVI-I dual-link signals, it supports VGA and HDMI interfaces with the use of the applicable adapters.

K204 is equipped with an RDC port enabling user-friendly, comfortable remote control of the KVM switch.

The K204 is built by design to provide highest possible isolation between four connected computers. It meets the requirements of companies challenged by the need to provide both secret and top-secret network access together with unclassified or Internet access.

The K204 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.

The products are fully compatible with EAL4+ and NIAP security requirements.
