summaries to final-data memory takes place when the Trigger argument in
the DataTable() instruction is set to True.
Term: data output processing memory
SRAM memory automatically allocated for intermediate calculations
performed by CRBasic data output processing instructions. Data output
processing memory cannot be monitored.
Term: dc
See Vdc
(p. 561).
Term: DCE
Data Communication Equipment. While the term has much wider meaning,
in the limited context of practical use with the CR3000, it denotes the pin
configuration, gender, and function of an RS-232 port. The RS-232 port on
the CR3000 is DCE. Interfacing a DCE device to a DCE device requires a
null-modem cable. See DTE
(p. 537).
Term: desiccant
A hygroscopic material that absorbs water vapor from the surrounding air.
When placed in a sealed enclosure, such as a datalogger enclosure, it prevents
condensation.
Term: DevConfig software
Device Configuration Utility
(p. 113),
available with LoggerNet, RTDAQ,
PC400, or at www.campbellsci.com/downloads.
Term: DHCP
Dynamic Host Configuration Protocol. A TCP/IP application protocol.
Term: differential
A sensor or measurement terminal wherein the analog voltage signal is
carried on two leads. The phenomenon measured is proportional to the
difference in voltage between the two leads.
