Section 11. Glossary 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. 454
