Section 11. Glossary
Term: output processing memory
See data output processing memory
(p. 495).
Term: PakBus
A proprietary comms protocol similar to IP
(p. 502) protocol developed by
Campbell Scientific to facilitate communications between Campbell
Scientific instrumentation. See PakBus — Overview
(p. 77) for more
information.
Term: PakBusGraph software
Shows the relationship of various nodes in a PakBus network and allows for
monitoring and adjustment of some registers
(p. 511) in each node. A PakBus
node is typically a Campbell Scientific datalogger, a PC, or a comms device.
See section Datalogger Support Software — Overview
(p. 86).
Term: parameter
Parameter
(p. 508): part of a procedure (or command) definition.
Argument
(p. 489): part of a procedure call (or command execution). An
argument is placed in a parameter. For example, in the CRBasic command
Battery(dest), dest is a parameter that defines what argument is to be put in
its place in a CRBasic program. If a variable named BattV is to hold the
result of the battery measurement made by Battery(), BattV is the argument
placed in dest. In the statement
Battery(BattV)
BattV is the argument.
Term: period average
A measurement technique using a high-frequency digital clock to measure
time differences between signal transitions. Sensors commonly measured
with period average include water-content reflectometers.
Term: peripheral
Any device designed for use with the CR800 (or another Campbell Scientific
datalogger). A peripheral requires the CR800 to operate. Peripherals
include measurement, control
(p. 82), and data retrieval and comms (p. 568)
modules.
