Cache Data
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 are set up to
mimic the storage areas in datalogger memory, and by default are two
times the size of the storage area. When the software collects data
from a CR800, the data are stored in the binary file for that CR800.
Various software functions retrieve data from the data cache instead of
the CR800 directly. This allows the simultaneous sharing of data among
software functions.
Similar in function to CR800 final storage tables, the binary file for a
datalogger is set up as ring memory. This means that as the file reaches
its maximum size, the newest data will begin overwriting the oldest
data.
Calibration Wizard Software
The calibration wizard facilitates the use of the CRBasic field calibration
instructions FieldCal() and FieldCalStrain(). It is found in LoggerNet (4.0
or higher) or RTDAQ.
Callback
A name given to the process by which the CR800 initiates
telecommunication with a PC running appropriate CSI datalogger
support software. Also known as "Initiate Telecommunications."
CD100
An optional enclosure mounted keyboard display for use with the
CR1000 and CR800 dataloggers. See the appendix Keyboard Display
(p.
code
A CRBasic program, or a portion of a program.
Com port
COM is a generic name given to physical and virtual serial
communications ports.
constant
A connector is a device that allows one or more electron conduits
(wires, traces, leads, etc) to be connected or disconnected as a group. A
connector consists of two parts — male and female. For example, a
common household ac power receptacle is the female portion of a
