The RBRcervata combines the extra power capacity of an RBRfermata with data controller capabilities to extend deployment autonomy and flexibility of RBR data loggers.

Data controller

Data collection

The RBRcervata will periodically download data from the attached instrument. And, when the instrument's internal storage gets too full, the data controller will stop and restart the deployment to minimize downtime.

Downloaded data is recorded to internal SD card storage media in RSK-format datasets compatible with Ruskin. These are not full-featured RSK files, and must be opened in Ruskin at least once before they can be opened by other RSK-compatible tools (such as RSKtools).

Energy conservation

The RBRcervata will enter a deep sleep mode whenever it is not downloading from the connected instrument. It will periodically wake itself, download any new data from the instrument, then return to sleep. The sleep duration can be configured to balance the trade-off between power consumption and the recency of data upon retrieval of the data controller.

Deployment management

The RBRcervata is able to alter instrument deployment parameters (e.g., sampling rate, bursting parameters). When an instrument's existing configuration doesn't match that which the data controller expects, it will stop and redeploy the instrument.

Power delivery

The RBRcervata integrates a full-sized RBRfermata battery assembly with either alkaline or lithium cells. The battery is used not only to power the RBRcervata itself, but to deliver power to the attached instrument.
