HSL-K304-E KM Switch


KM Switch for use in many cases where one computer user needs to work simultaneously with few computers. In some cases users are having multiple displays attached to these multiple computers. The challenge is how a single user can interact with multiple computers having multiple displays. KVMs would not do a good job for these users as they were designed to switch displays as well. KM switch is a device that switches a single set of keyboard and mouse between multiple computers. KM switch is essentially a KVM switch without the video switching - all displays are continuously connected to their computers. This is a Secure KM switch which is a KM switch device that specifically designed to enable isolation between coupled computers. Computers are typically connected to different networks and isolation between these networks must be assured to prevent data leakages and intrusions across networks. Secure KM switch relies on physics (optical diodes) to prevent data leakages between coupled networks. Secure KM switch does not require any cables between computers any shared bus or network or any installed software. Virtual Display Technology (VDT) is implemented in HSL K304 Secure KM switches to enable seamless cursor and keyboard switching between multiple displays. VDT allows administrators to configure any desired displays configuration with same or different size and resolution. User simply moves mouse cursor across neighbouring displays to switch between connected computers.


• Virtual Display Technology allows the K304 to switch automatically between computers once mouse cursor crosses display borders.
Highest security by design
• Designed by agency to support isolation between national security networks. Common-Criteria EAL 4+ approved (pending). Derivative of a TEMPEST product used in NATO nuclear submarines. Support for multiple head
• Product can be easily configured to support dual, triple and up to 16 head computers through signed software driver. Single head installation does not need any software installation. Unidirectional optical data diodes
• Assuring USB peripherals isolation. Data can flow from devices to computer only. No reverse data flow possible by optical diodes. User authentication device port
• Special USB port that supports CAC and other user authentication devices including biometric readers. User can decouple this port from KVM switching to remain authenticated on one channel in needed. Extensive administrator setup options
• Administrator mode provides many customized settings from display arrangement, size to cursor speed and acceleration. Independent audio switching
• Audio output can be configured to follow the cursor or can be set by the user to any channel.
Anti tampering
• Always on active anti-tampering with 10 years battery. Special holographic tampering evident labels.
