Overview

The SC-CPI adds CPI bus functionality to your CR800, CR850, CR1000, and CR3000 dataloggers, which is necessary for them to connect to the CDM (Campbell Distributed Module) devices and other CPI-enabled sensors. The SC-CPI connects to the data logger using the C1, C2, and C3 ports.

The SC-CPI is not required for, or supported by, data loggers with a native CPI interface. Campbell Scientific strongly recommends that CDMs be connected to data loggers with a native CPI interface, such as the CR6.

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

Additional Compatibility Information

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.

Downloads

SC-CPI OS v.04 (477 KB) 10-10-2016

Execution of this download installs the SC-CPI Operating System on your computer for upload to the SC-CPI device with Device Configuration Utility.

Note: The SC-CPI OS V.02 or greater is required to use the CDM-VW300/305 with the CR3000/1000/800 datalogger that is using OS 28 or higher.  The CDM-VW300/305 Operating System will also need to be upgraded to CDM-VW300/305 OS V.02.  If using a CR3000/1000/800 datalogger with an older OS, an operating system upgrade to the datalogger will be required.

Frequently Asked Questions

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 data logger is required. It is expected that the design of future Campbell Scientific data logger products will 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.
