support software
Includes PC200W, PC400, RTDAQ, LoggerNet, and LoggerNet clients.
Brief descriptions are found in Datalogger Support Software
(p. 77). A
complete listing of datalogger support software available from Campbell
Scientific can be found in the appendix Software
(p. 569). Software
manuals can be found at www.campbellsci.com.
synchronous
The transmission of data between a transmitting and a receiving device
occurs as a series of zeros and ones. For the data to be "read" correctly,
the receiving device must begin reading at the proper point in the
series. In synchronous communication, this coordination is
accomplished by synchronizing the transmitting and receiving devices to
a common clock signal (see Asynchronous
(p. 447) ).
system time
When time functions are run outside the Scan() / NextScan construct,
the time registered by the instruction will be based on the system clock,
which has a 10‐ms resolution. See scan time
(p. 464).
task
1) Grouping of CRBasic program instructions by the CR1000. Tasks
include measurement, SDM, and processing. Tasks are prioritized by a
CR1000 operating in pipeline mode. 2) A user‐customized function
defined through LoggerNet Task Master.
TCP/IP
Transmission Control Protocol / Internet Protocol.
Telnet
A software utility that attempts to contact and interrogate another
specific device in a network.
constant
A terminal is the point at which a single wire connects to a wiring panel
or connector. Terminals are usually secured with small screw‐ or spring‐
loaded clamps. See connector
(p. 450).
terminal emulator
A command‐line shell that facilitates the issuance of low‐level
commands to a datalogger or some other compatible device. A
