Additional Compatibility Information

Card Format

Currently, the CFMC256M is formatted as FAT32; our contemporary data loggers require this format for the card to work as expected. Cards purchased before August 2008 were formatted as FAT16. Our CC640 camera (retired), the CR9000 dataloggers (retired), and CR5000 dataloggers with older operating systems need the FAT16 format. A card formatted as FAT32 can be reformatted as FAT16.

展开全部Collapse All

  1. What is the largest memory card that can be used with a CR9000X?

    2 GB.

  2. CR5000可以使用的最大存储卡是什么？

    With OS 7 or greater and theTableFile()instruction withOption 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 Cards”application note.

  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.

  5. What is the largest CompactFlash memory card that can be used with the CR3000 or CR1000?

    With operating system 25 or greater, the CR3000 works with CF cards in sizes up to 16 GB using theTableFile()instruction andTFOption 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 Cards”application note.

  6. How should a CompactFlash card be formatted?
    The most reliable method of formatting a CompactFlash (CF) card is to format it using a PC and specifying FAT32.
