How it is built

One-way path
Data path
Path that does not exist

Field sensors in an environment without maintenance. The unit is replaced, not opened.

Used in these environments

Mobile command postThe zone moves with the vehicle, and the boundary is decided where the vehicle happens to stop.
Sensor data from the fieldVibration, temperature range and DC supply, and no maintenance while deployed.
Vehicle and vessel installationThe rugged data diodes carry 810G and 461 data; no converter, extender or switch in the catalogue does.
Field workstationThere is no room, no wall and no property owner — the zone has to be carried along.
Command post in a vehicle or containerMaintenance during operation does not exist. Spare parts strategy and lifecycle commitment are part of the architecture.

How it works

Sensors in the field feed a rugged one-way link to a command post. The environment sets the requirements before the data does: vibration, temperature range, DC supply — and no maintenance while deployed.

The unit is replaced, not opened

A sealed unit that has to be opened to be fixed is a unit that loses its seal in a field workshop. Spare parts strategy and lifecycle commitment are part of this architecture, not an appendix to it.

No control goes back

The link carries observations out. Anything that wants to configure a sensor from the command post is a second link with its own approval, and in most field installations it should simply not exist.
