  1. With OS 7 or greater and the TableFile() instruction with Option 64, CompactFlash cards greater than 2 GB can be used. For more information, see the “A Better Way to Write High-Frequency Data to 16 GB and Smaller CF Cardsapplication note.

  2. 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.

  3. Using the FileControl() 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 a GetData() 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.

  4. With operating system 25 or greater, the CR3000 works with CF cards in sizes up to 16 GB using the TableFile() instruction and TFOption 64. For earlier versions of the operating system, the largest compatible CF card size is 2 GB.

    For more information, see the “A Better Way to Write High-Frequency Data to 16 GB and Smaller CF Cardsapplication note.

  5. The most reliable method of formatting a CompactFlash (CF) card is to format it using a PC and specifying FAT32.
