Adder AVS-4128 – ADDERView Secure 8-Port DP/HDMI Flexi-Switch

Product Overview

The Adder AVS-4128 is an ADDERView Secure Flexi-Switch, an 8-port secure KVM switch designed to NIAP Protection Profile 4.0 for environments where operators must work across networks of different classification levels from a single desk. Its eight computer ports accept a combination of single-head and dual-head sources over DisplayPort and HDMI, giving the user real-time control of up to two computers simultaneously. For agencies and contractors evaluating a NIAP PP 4.0 secure KVM switch with 4K60 video support, the AVS-4128 provides more flexibility than a standard 4-port secure switch while maintaining strict isolation between connected systems.

Product Description

Secure desktops in defense, intelligence, and government settings often require access to more isolated networks than a conventional secure KVM allows. The Flexi-Switch architecture answers this by treating the eight inputs as a flexible pool: connect eight single-head computers, four dual-head computers, or a mixture, and switch among them while keeping every data path electrically and logically separated. Video performance supports UHD 4K resolution up to 3840x2160 at 60Hz, suitable for graphics-intensive analysis and mapping applications.

Security is engineered into the hardware. Uni-directional optical diodes force data paths to travel in one direction only, preventing data leakage through shared peripherals; the same uni-directional structure protects against timing analysis and forced-malfunction attacks and prevents any connected computer from influencing common circuitry. Configurable LED buttons and a real-time status display keep the operator aware of which source is selected at all times, reducing the risk of input errors in multi-domain work.

Host compatibility covers Windows, Linux, and Mac systems using USB HID, including touchscreens compliant with the Microsoft Digitizer specification. The switch carries CE, FCC Class A, and TUV US and Canada approvals alongside its NIAP PP 4.0 compliant design and TAA compliance, simplifying procurement for US government programs.

Technical Specifications

Frequently Asked Questions

What does NIAP PP 4.0 compliance mean for my deployment?
The switch is designed to the current NIAP Protection Profile for Peripheral Sharing Devices, the standard referenced by US government and defense programs for secure KVM procurement.

How does the Flexi-Switch differ from a fixed 8-port secure KVM?
The eight inputs can be assigned to a mixture of single-head and dual-head computers rather than a fixed port-per-computer layout, and the operator can control up to two computers at once.

Which operating systems are supported?
Windows, Linux, and Mac hosts are supported through standard USB HID, with touchscreen support for Microsoft Digitizer compliant devices.

How is data leakage between networks prevented?
Uni-directional optical diodes enforce one-way data flow, and isolated circuitry prevents any connected computer from influencing shared components or other channels.

Is the AVS-4128 TAA compliant for US federal purchases?
Yes. The product is TAA compliant and carries CE, FCC Class A, and TUV US and Canada approvals.

Can Creation Networks help spec a secure KVM room design?
Yes. Our team supports government and enterprise integrators with secure KVM selection and room design; contact us for configuration assistance.
