DCE
Data communications 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 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
Device Configuration Utility (p. 97), available with LoggerNet, RTDAQ,
PC400, or a www.campbellsci.com.
DHCP
Dynamic Host Configuration Protocol. A TCP/IP application protocol.
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.
digital
Numerically presented data.
Dim
A CRBasic command for declaring and dimensioning variables. Variables
declared with Dim remain hidden during datalogger operations.
dimension
To code for a variable array. DIM example(3) creates the three variables
example(1), example(2), and example(3). DIM example(3,3) creates nine
variables. DIM example (3,3,3) creates 27 variables.
DNS
Domain name system. A TCP/IP application protocol.
