neighbor does not communicate for a period of time equal to 2.5 x the

the neighbor is removed from the neighbor list.
datalogger support software
Campbell Scientific software that includes at least the following
functions:
o Datalogger telecommunications
o Downloading programs
o Clock setting
o Retrieval of measurement data
Includes PC200W, PC400, RTDAQ, and LoggerNet suite. For more
information, see Datalogger Support Software
(p. 76)
and the appendix
Datalogger Support Software
(p. 547).
data point
A data value which is sent to final storage
(p. 432)
as the result of an
output processing (data storage) instruction. Strings of data points
output at the same time make up a record in a data table.
dc
See Vdc
(p. 447).
DCE
Data communications equipment. While the term has much wider
meaning, in the limited context of practical use with the CR800, it
denotes the pin configuration, gender, and function of an RS‐232 port.
The RS‐232 port on the CR800 and on many third‐party
telecommunications devices, such as a digital cellular modems, are DCE.
Interfacing a DCE device to a DCE device requires a null‐modem cable.
desiccant
A material that absorbs water vapor to dry the surrounding air.
DevConfig
