Issue Details

In versions of NI-RIO prior to 2.4, C Series Modules only return binary (uncalibrated) data, which requires the host VI to apply calibration coefficients and convert the data to engineering units in software. After installing NI-RIO 2.4 or later, the default behavior for AI/AO modules is to use calibrated data.  Where can I find information on using Fixed-Point Data with CompactRIO and LabVIEW FPGA?
