3. What is the fastest way to download more than 5 million records from a CR5000 to a PC?

   Save the data to a CompactFlash card. Transfer the data from the CR5000 to the PC by removing the card from the CR5000 and inserting it into the PC.

4. Using a CompactFlash module, a data logger, and the BMP5 Direct SDK, how can data be downloaded from the memory card instead of the CPU buffer?

   Using theFileControl()instruction, the .dat files can be retrieved directly from the memory card. When data is collected by the standard method (not as downloaded files, but as streamed data) with aGetData()or similar instruction, the memory card is automatically used as a source of records to be returned when the internal CPU table no longer contains the oldest data. These records can be retrieved simply by using their record numbers.
