Overview

The SC-CPI is an interface between the serial port of later-model Campbell Scientific dataloggers (CR800/850, CR1000, and CR3000) and our new Campbell distributed modules (CDMs). The CDMs use the new CAN peripheral interface (CPI), and the SC-CPI allows the dataloggers listed above to connect to the CDM's CPI port. Future dataloggers will have CPI connections and will not need a bridge, but with the SC-CPI our current line of dataloggers will be able to take advantage of our CDM technology.

Benefits and Features

  • Enables a CR800, CR850 CR1000, or CR3000 to be part of a CPI/CDM network
  • Provides detailed CPI communication diagnostics
  • Supports monitoring of the serial or CPI load
  • Indicates if CPI frame errors occur
  • Provides information about each CPI module that it detects in its network

Data Logger Considerations

A 5-conductor cable connects the data logger to the SC-CPI, and an Ethernet cable connects the SC-CPI to the CDM.

The data logger operating system must be version OS 26.


Related FAQs

Number of FAQs related to SC-CPI: 2

  1. To communicate with CDM devices using the CPI protocol, the CR3000, CR1000, CR850, and CR800 dataloggers require an SC-CPI device. Only one SC-CPI device per datalogger is required. It is expected that the design of future Campbell Scientific datalogger products will be work with CPI-based modules directly.

  2. The communications protocol used by CDM devices is the CAN Peripheral Interface (CPI), which includes methods that are proprietary to Campbell Scientific.
