Description
The National Instruments 781496-01 cDAQ-9181 CompactDAQ Chassis is a 1-Slot Ethernet chassis compatible with C Series input modules for measuring slowly varying signals like temperature. Modules should not have the AI Sample Clock set slower than their maximum rate, but can run faster than the module’s max rate.
The National Instruments cDAQ-9181 CompactDAQ Chassis, part number 781496-01, is a 1-Slot Ethernet chassis that is compatible with C Series simple input modules designed for measuring slowly varying signals, such as temperature. It is important to note that these modules should not have the AI Sample Clock set to a rate slower than their maximum rate. When using a module with the cDAQ-9181 chassis, the maximum sample rate can actually run faster than the module's maximum rate. The chassis also allows for the use of Reference Trigger to stop measurement acquisition. By specifying a buffer size and pre-trigger samples, users can capture data before and after the trigger event. To create a simple input, simply insert a C Series module into any slot on the cDAQ-9181 chassis. The specifications of the measurement, such as channels, channel configuration, refresh rate, and output range, are determined by the type of C Series module being used. It is important to note that on a single simple output module, channels can be assigned to hardware scheduled tasks or software scheduled tasks, but not both.
