This Adder AVS-4214 Dual-Head Secure 4-Port Switch enable a KVM plus audio desktop to be shared between different classification level computers. Designed for superior usability, the switches feature configurable LED buttons and a real-time status display.

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.

Adder AVS-4214 Dual-Head Secure 4-Port Switch 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.
• 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.
• 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): Switch channels (KVM plus audio) simply by moving the mouse across the screen border, whilst pressing the Ctrl key.
• Hardware anti-tampering: Holographic anti-tampering labels protect the product's enclosure, providing a clear visual indication if it has been opened or compromised.
• 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.
• Video Performance: Up to UHD 4K video resolution at 60 fps for graphics intensive applications requiring very high quality.
• Audio hold: Assign the audio port to a specific computer while switching the KVM to other computers. Useful when a user needs to listen to audio from one computer, whilst working on another.
