Adderview Secure multi-viewer switch for sharing KVM, plus analog audio between four computers spanning multiple security classification levels.

• NIAP PP 4.0 Compliant Design
• Made in America
• TAA Compliant

• Uni-directional keyboard, video, mouse and audio data paths: Computer video input interfaces are isolated through use of separate electronic components and power. The display is isolated by a dedicated, read-only, EDID (Extended Display Identification Data) emulation for each computer. Access to the monitor’s EDID and MCCS (Monitor Control Command Set) commands are blocked.
• Automatic switching: Free-flow KVM and audio control between ports without the need to press any buttons. Simply move the mouse between windows.
• No shared RAM between channels: The keyboard and mouse processor is powered down and reset at each switchover to thwart shared RAM leakages. All data buffers are actively cleared once they have been used.
• Hardware anti-tampering: Holographic anti-tampering labels protect the product’s enclosure, providing a clear visual indication if it has been opened or compromised.
• Channel identification: Reduce the chances of operator error by displaying a name for each channel and its security classification on the E-paper display. The color of the channel LED may also be configured to reflect the security classification.
• Video Performance: Up to UHD 4K video output resolution is generated, thus the input signal quality is preserved, even in tile window layout.
• Non-reprogrammable firmware: There is no access to the product’s firmware or memory through any port. Firmware is permanently stored in non-reprogrammable Read Only Memory (ROM) to prevent modification. Firmware integrity is verified through a self-test procedure during power up. Detection of a critical failure disables the device and provides a clear visual indication to the user.
• Restricted USB function: The USB ports will only accept HID (Human Interface Devices), such as keyboards and mice. Other devices, such as USB storage drives, are actively prohibited.
