data output processing instructions
CRBasic instructions that process data values for eventual output to final-data memory.
Examples of output-processing instructions include Totalize(), Maximize(), Minimize(), and
Average(). Data sources for these instructions are values or strings in variable memory. The
results of intermediate calculations are stored in data output processing memory to await
the output trigger. The ultimate destination of data generated by data output processing
instructions is usually final-storage memory, but the CRBasic program can be written to
divert to variable memory by the CRBasic program for further processing. The transfer of
processed summaries to final-data memory takes place when the Trigger argument in the
DataTable() instruction is set to True.
data output processing memory
Memory automatically allocated for intermediate calculations performed by CRBasic data
output processing instructions. Data output processing memory cannot be monitored.
data point
A data value which is sent to final-data memory as the result of a data-output processing
instruction. Data points output at the same time make up a record in a data table.
data table
A concept that describes how data is organized in memory, or in files that result from
collecting data in memory. The fundamental data table is created by the CRBasic program as
a result of the DataTable() instruction and resides in binary form in memory. The data table
structure resides in the data cache, in discrete data files, and in files that result from
collecting final-data memory with data logger support software.
DC
Direct current.
DCE
Data Communications Equipment. While the term has much wider meaning, in the limited
context of practical use with the data logger, it denotes the pin configuration, gender, and
function of an RS-232 port. The RS-232 port on the data logger is DCE. Interfacing a DCE
device to a DCE device requires a null-modem cable.
