AVS-4128 KVM Switch

ADDERView AVS-4128 4K Video DisplayPort/HDMI Dual Monitor 4-Port KVM Switch, USB Keyboard & Mouse, With Audio.

ADDERView® Secure AVS 4128 Flexi-Switch

Secure KVM flexi-switch for sharing single or dual-head 4K video, USB keyboard and mouse, plus analog audio between eight computers spanning multiple security classification levels.

The ADDERView® Secure Flexi-Switch 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 that can be connected to a combination of single and dual-head computers; giving the user real-time control of up to two computers simultaneously.

Features

Video Performance
Up to UHD 4K video resolution at 60 fps for graphics intensive applications requiring very high quality.

Flexible Connections
The user can switch between a combination of single and dual-head computers. Two single-head computers can be controlled concurrently.

Uni-Directional Data Paths
Uni-directional optical diodes ensure data paths travel in only one direction to prevent 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.

Non-Reprogrammable Firmware
Firmware is permanently stored in non-reprogrammable Read Only Memory (ROM) to prevent modification, and cannot be accessed by any port. A self-test at power-up verifies its integrity, and if a critical failure is detected, the device is disabled and provides a clear visual indication to the user.

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.

Uni-Directional Video and Audio
Computer input interfaces are isolated through use of separate uni-directional optical data diodes 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 commands are blocked.
