The CFM100 stores the datalogger's data on a removable CompactFlash (CF) card. The CFM100/CF card combination can be used to expand the datalogger's memory, transport data/programs from the field site(s) to the office, and upload power up functions. The module connects to the 40-pin peripheral port on a CR1000 or CR3000 datalogger.
The CFM100 includes a card slot that can fit one Type I or Type II CF card. Only industrial-grade CF cards should be used with our products. Although consumer-grade cards cost less than industrial-grade cards, the consumer-grade cards are more susceptible to failure resulting in both the loss of the card and its stored data. Industrial-grade cards also function over wider temperature ranges and have longer life spans than consumer-grade cards.
Data stored on the card can be retrieved either by removing the card and carrying it to a computer or through a communications link with the datalogger. The computer can read the CF card either with the computer’s PCMCIA slot and the CF1 adapter or the computer’s USB port and the 17752 Reader/Writer.
CardConvert is used to convert and save binary data from a CompactFlash card. CardConvert is included in our PC200W, PC400, LoggerNet, and RTDAQ datalogger support software.

Campbell Scientific offers and recommends several CF cards (see Ordering tab). These cards have passed Campbell Scientific's ESD testing and operate properly with our data loggers.

The CFM100 fastens onto the data logger's 40-pin peripheral port. This means that the CFM100 is only compatible with the CR1000 and CR3000. It is NOT compatible with the CR800, CR850, CR200X, CR5000, or CR9000X dataloggers.
To read cards with more than 2 GB of storage, the data logger operating system must be OS 25 or later.

The CFM100 does not have any diagnostics that can be reported. The Status table does report the status of the CompactFlash card and the number of bytes free on the CF card.
The file on the card is open until the program is stopped or the button on the device is pressed.
LoggerNet collects data from the data logger first. If there is additional data on a CompactFlash card, LoggerNet collects that also. Nothing special needs to be set up in LoggerNet to have this occur.
For detailed information, review the information in the “CF Card Information” application note.
The best way to collect data from a CF card, with large or many files on it, is to physically remove the card and read the data from the card using a PC. Data can be collected using LoggerNet and a communications link; however, the link must use a high-frequency collection schedule. Some communications links are not practical because of speed or cost limitations.
The best practice is to format the CF card, not using “Quick Format” on a PC, before inserting it into a device.
Review the CRBasic Editor Help for information on the TableFile() instruction.
When the CardOut() instruction or the TableFile() with TFOption 64 instruction is used, the data table is saved to both the data logger’s internal memory and the card.
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.
