Environments
Used in these environments
9 real installations, filterable by area
Showing all 9 environments
- 01KVM & VTC
Control room with several networks
Shared peripherals are the channel between the domains, and an ordinary KVM switch shares EDID, USB state and sometimes memory. - 02TEMPEST/RÖS
Command and control centre
Several networks meet at one desk, and the operator must never have to think about which one is in front of them. - 03TEMPEST/RÖS
Mobile command post
The zone moves with the vehicle, and the boundary is decided where the vehicle happens to stop. - 04TEMPEST/RÖS
Naval vessel
A hull is an electromagnetically dense environment where every cable run is shared with something else. - 05Data diodes
Sensor data from the field
Vibration, temperature range and DC supply, and no maintenance while deployed. - 06KVM & VTC
Training facility
Students bring their own devices, and a room designed for teaching is designed to be connected to. - 07Data diodes
Vehicle and vessel installation
The rugged data diodes carry 810G and 461 data; no converter, extender or switch in the catalogue does. - 08TEMPEST/RÖS
Field workstation
There is no room, no wall and no property owner — the zone has to be carried along. - 09Data diodes
Command post in a vehicle or container
Maintenance during operation does not exist. Spare parts strategy and lifecycle commitment are part of the architecture.

- TE-AThe single workstation in a Level A zoneThe indivisible zone: every device in the chain carries the level, and the weakest one sets it.
- KV-AShared workstation with physical KVM switchingFour properties separate a secure KVM from an ordinary one: EDID emulation, one-way HID, no shared buffer, tamper indication.
- TE-BRemote computer: KVM over fiberThe zone shrinks to the presentation surface, and the desk becomes an extension of the computer.
- KV-CThe display as a pure receiverHDMI is not one-way: DDC runs in both directions, and EDID is a shared, writable object.
