Term: cr
Carriage return
Term: CRBasic Editor
The CRBasic programming editor; supplied as part of LoggerNet, PC400,
and RTDAQ software
Term: CRBasic Editor Compile, Save and Send
CRBasic Editor menu command that compiles, saves, and sends the program
to the datalogger.
Term: CRD
An optional memory drive that resides on a memory card. See
CompactFlash
(p. 532).
Term: CS I/O
Campbell Scientific proprietary input / output port. Also, the proprietary
serial communication protocol that occurs over the CS I/O port.
Term: CVI
Communication verification interval. The interval at which a PakBus®
device verifies the accessibility of neighbors in its neighbor list. If a neighbor
does not communicate for a period of time equal to 2.5 times the CVI, the
device will send up to four Hellos. If no response is received, the neighbor is
removed from the neighbor list. See the section PakBus — Overview
(p. 82)
for more information.
Term: data cache
The data cache is a set of binary files kept on the hard disk of the computer
running the datalogger support software
A binary file is created for
each table in each datalogger. These files mimic the storage areas in
datalogger memory, and by default are two times the size of the datalogger
storage area. When the software collects data from a CR3000, the data are
stored in the binary file for that CR3000. Various software functions
retrieve data from the data cache instead of the CR3000 directly. This
allows the simultaneous sharing of data among software functions.
Similar in function to a CR3000 final-storage data tables, the binary files for
the data cache are set up by default as ring memory
(p. 552).
