Dear User,
Thank you for using the NI Developer Zone.
In LabVIEW the only way to get 24 bits data from the NI-4472 is to use the AI READ function with Scaled data and the selected data type. It is not possible at this moment to read more than 16 bits in binary representation.
So what I suggest you is to store the acquired scaled data in binary format, instead of reading the binary data straight from the board.
Best Regards,
