The ADDERView Secure 4-Port DVI Single-Head Switch from Adder allows users to control and switch between four computer systems, no matter the operating system. This switch supports systems with DVI outputs to give a clear and smooth image at resolutions up to 1920 x 1200 @ 60 Hz. Connect peripherals such as a mouse and keyboard to the two USB-A inputs. Audio transfer through headphones or speakers can also be done via the 3.5mm jacks. Adder has integrated front-panel switches, multi-color status LEDs, and an E-Paper display to easily determine the connected system and its current configuration, while also quickly switching to your desired connection.
Unidirectional Data Paths
This switch features unidirectional optical diodes which ensure data paths travel in only one direction to prevent data leakage through shared peripherals. A unidirectional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.
Channel Identification
Channel identification is made easy because this switch displays 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.
Non-Reprogrammable Firmware
The firmware of this switch 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.
Unidirectional Video
Computer video input interfaces are isolated through use of separate electronic components and power. This 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.
No Shared RAM Between Ports
There is no shared RAM between the ports, as 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
You can 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.
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.
Audio Hold
You can assign the audio port to a specific computer while switching the KVM to other computers. This is useful when a user needs to listen to audio from one computer whilst working on another.
Unidirectional Audio
The unidirectional audio enforces computer-to-speaker, one-way flow of sound through unidirectional optical data diodes, which prevents eavesdropping and line-in retasking by blocking speaker-to-computer communication.
Industry Recognized
This switch is NIAP PP 4.0 certified, TAA-compliant, and assembled in the USA.
