Synchronized high-speed measurements
概览
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.
An SC-CPI is required to connect Campbell Distributed Modules (CDMs), such as the CDM-A116, to a CR800, CR850, CR1000, or CR3000 datalogger. The SC-CPI is not required for, or supported by, dataloggers with a native CPI interface. Campbell Scientific strongly recommends that CDMs be connected to dataloggers with a native CPI interface, such as the CR6.
优势与特点
- 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.
常见问题解答
SC-CPI: 2
-
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.
-
The communications protocol used by CDM devices is the CAN Peripheral Interface (CPI), which includes methods that are proprietary to Campbell Scientific.
