The CFM100 stores the data logger's data on a removable CompactFlash (CF) card. The CFM100/CF card combination can be used to expand the data logger'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.Read More

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
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.
Only industrial-grade CF card 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 through a communications link with the data logger or by removing the card and carrying it to a computer. 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.
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.
Campbell Scientific always recommends using CF cards carried by Campbell Scientific. Although another CF card might fit and work with a CFM100 or NL115, the CF card might not be rated for the same temperature range as the CFM100 or NL115. In addition, another CF card might not have the same electrostatic discharge (ESD) immunity as the cards tested and carried by Campbell Scientific. For more detail on CF cards, see the “CF Card Information” application note.
The best practice is to format the CF card, not using “Quick Format” on a PC, before inserting it into a device.
The CFM100 or NL115 is detected during the data logger boot-up cycle, that is, when it is powered on. Disconnect or connect the CFM100 or NL115 to a data logger only after power to the data logger has been disconnected.
If the CardOut() or TableFile() instructions are configured as fill and stop, the data logger will stop writing data to the CompactFlash cards after they are full.
For detailed information, review the information in the “CF Card Information” application note.
No. Only a program change could cause this. To save data to a CFM100 or an NL115, a CardOut() or TableFile() instruction must be present in at least one data table.
