ADDERView AVS-4128 Overview

The ADDERView Secure FlexiSwitch has been designed for applications that require more functionality than a standard 4-port KVM switch can provide. The Secure Flexi-Switch has eight input computer ports which can be connected to a combination of single and dual-head computers; giving the user real-time control of up to two computers simultaneously.

The ADDERView Secure range is designed to prevent sensitive data leakage and data storage in the device. Using features such as uni-directional data paths, anti-tamper labels and nonreprogrammable firmware, the secure switches actively combat a range of potential threats.

AVS-4128 Features

  • Uni-directional keyboard, video, mouse and audio data paths
    • Uni-directional optical diodes ensure data paths travel in only one direction, thus preventing data leakage through shared peripherals. A uni-directional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.
    • Keyboard locks status
      • Indicate status of keyboard locks (CAPS-LOCK, NUM-LOCK, SCROLL-LOCK) that are blocked by uni-directional data paths.
    • 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.
    • Automatic switching (configuration option)
      • Free-flow KVM and audio control between ports without the need to press any buttons. Simply move the mouse between windows.
    • Flexible connections
      • The user can switch between a combination of single and dual head computers. Two single head computers can be controlled concurrently.
    • Hardware anti-tampering
      • Holographic anti-tampering labels protect the product's enclosure, providing a clear visual indication if it has been opened or compromised.
    • Video Performance
      • Up to UHD 4K video resolution at 60 fps for graphics intensive applications requiring very high quality.
    • 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.
    • 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.
