11. Glossary
CPI
CAN Peripheral Interface — A proprietary protocol that supports Campbell
Distributed Modules (CDMs). The CPI bus handles communication between
the datalogger and CDMs.
CRBasic Editor
A utility included with datalogger support software. Use it to create and edit
CRBasic datalogger programs. Update the CRBasic compiler by downloading
the appropriate datalogger operating systems at
www.campbellsci.com/downloads and running the downloaded executable file.
DevConfig (Device Configuration Utility)
A utility included with datalogger support software. It is also available on the
ResourceDVD and at
www.campbellsci.com/downloads . The CDM-A100
series is compatible with DevConfig 2.11 and newer.
Datalogger Support Software
For the purposes of the CDM-A100 series, these include LoggerNet, PC400,
PC200W, and RTDAQ.
LED (Light Emitting Diode)
Lights on all CDM-A100s and related instruments are LEDs. For more
information, see TABLE
10-2 , COMM Status LED Activity
(p. 31)
, and TABLE
10-3 , CPI Port LED Activity
(p. 31).
OS (Operating System)
The CDM-A100, datalogger, and SC-CPI each have an operating system. The
operating system is a set of instructions that controls the basic functions of the
device. The operating system is preloaded into the CDM-A100, the datalogger,
and the SC-CPI at the factory but can be re-loaded or upgraded by using
Device Configuration Utility software. Follow the procedure on the Device
Configuration Utility Send OS tab to load a new OS to a device.
Pipeline Mode
A mode of processing a program which handles measurement, most digital,
and processing tasks separately, and possibly simultaneously. Measurements
are scheduled to execute at exact times and with the highest priority, resulting
in more precise timing of measurement, and usually more efficient processing
and power consumption. The datalogger automatically sets the processing
mode according to the instructions in the program; however, it can be forced to
pipeline mode by using the PipelineMode instruction at the beginning of the
program.
