Description
The National Instruments cDAQ-9181 CompactDAQ Chassis, identified by part numbers 782052-01 and 781496-01, is a versatile 1-slot Ethernet chassis compatible with C Series simple input modules designed for measuring signals that change gradually, such as temperature.
This chassis is capable of handling sample rates that may exceed the maximum rate specified for the input module, offering flexibility in measurement speed and performance. It includes a reference trigger feature that allows users to halt an estimation acquisition effectively, providing precise control over the measurement process.
Users can configure the device with a finite buffer size to manage pre-trigger and post-trigger sample collection, ensuring that adequate data is captured for analysis. Simple input creation is straightforward, requiring the insertion of a C Series module into the chassis.
The type of C Series module used dictates the specific age determinations, including the number of channels, channel configuration, refresh rate, and output range. Task assignment is flexible, allowing channels on a single simple output C Series module to be designated as either hardware timed or software timed (single-point).
