With four connected dual-head computers, the K244 offers impressive levels of seamless communications even when connecting computers that are on different levels of security clearance and Internet access. Users can set up two displays to get the most out of dual-head computers. The K244 utilizes unidirectional optical data-diodes which insulates all connections from any possible points of data leakage among peripherals. Every K244 secure KVM switch is rigorously and extensively tested to ensure it will remain stalwart against any known form of KVM security attacks. The unit has been certified to meet EAL 4+ standards to assure it provides the highest level of security possible.

This product offers the highest possible separation between two connected computers. The K244 uses unidirectional optical data diodes to prevent any potential leakage between the highly-isolated peripheral channels. This KVM can also be used to securely filter and lock USB ports preventing data export / import through mass-storage devices by hardware.

Question: Is this unit 19" rack mountable?
Answer: Thank you for your inquiry,

The SmartAVI KH244E secure KVM was designed for easy rack-mounting in data centers and server rooms - however the optional rack-mounting kit is scheduled for release in about a week from today (~ 7/04/2016). SmartAVI does not have a part number available for the kit yet but we email you as soon as it is released.

Thank you for your patience as we investigated the release plan with SmartAVI manufacturing.
