DMU801 collects and processes data from the sensors according to a set configuration. To process the observation data, DMU801 performs advanced algorithm calculations. In addition, DMU801 validates sensor data accuracy using preconfigured criteria before sending the data forward. DMU801 also manages internal diagnostics of the system and reports the system status through a configurable reporting interface.
The sensors are connected to DMU801 through plug‑in modules. DMU801 controls the power of the sensors and provides heating power through a separate connector.
DMU801 has an embedded web server through which observation data, sensor status, and many DMU801 maintenance functions can be managed. Information can be viewed and managed through a browser-based graphical user interface, the DMU801 Web UI.
DMU801 has an 8 GB internal eMMc Flash memory, of which 4 GB can be used for data logging. The logging capability can be extended with an external SD memory card. The data is logged in daily files, which makes it easy to locate any particular data set for further analysis. DMU801 supports SD cards of up to 32 GB.
