Section 11. Glossary
Term: CDM/CPI
CPI is a proprietary interface for communications between Campbell
Scientific dataloggers and Campbell Scientific CDM peripheral devices. It
consists of a physical layer definition and a data protocol. CDM devices are
similar to Campbell Scientific SDM devices in concept, but the use of the
CPI bus enables higher data-throughput rates and use of longer cables. CDM
devices require more power to operate in general than do SDM devices.
