Module Overview
Campbell Scientific’s CFM100 CompactFlash
®
Module stores the datalogger’s data on a
removable CompactFlash (CF) card. The CFM100 module connects to the datalogger via the
40-pin peripheral port. Currently, only our CR1000 and CR3000 dataloggers have the 40-pin
peripheral port; the CFM100 is not compatible with the CR200-series, CR800, CR850,
CR5000, and CR9000X dataloggers.
This section of the manual surveys the CFM100 and its function. It also explains how to
quickly begin using a CFM100 for straightforward data storage operations. The remainder
of the manual is a technical reference which describes in detail such operations as: file
formats, datalogger programming and data retrieval.
