The CDAU-2020 is a high-speed airborne instrumentation controller with embedded DAU capability that operates at rates up to 20 Mbps. The unit operates as a data acquisition formatter/controller communicating and collecting data from distributed CAIS acquisition units. Composite data is available for recording, data archive or real‑time analysis. Subsets of data are available to support telemetry and flight safety analysis and monitoring. The unit also contains a complete CAIS data acquisition unit (based on the CDAU-2010) resulting in a highly efficient solution for controlling a distributed data acquisition system and acquiring a limited number of local acquisition channels.
