Term: Dim
A CRBasic command for declaring and dimensioning variables. Variables
declared with Dim remain hidden during datalogger operations.
Term: dimension
Verb. To code a CRBasic program for a variable array as shown in the
following examples:
o
DIM example(3) creates the three variables example(1) ,
example(2) , and example(3) .
o
DIM
example(3,3) creates nine variables.
o DIM example(3,3,3) creates 27 variables.
Term: DNS
Domain name system. A TCP/IP application protocol.
Term: DSP
Digital signal processing. A technique for converting analog voltage to a
digital value by means of over-sampling with an analog-to-digital converter
and applying statistical and filtering techniques to arrive at veryhigh
resolution measurements. A resource for learning about DSP is the book
The Scientist and Engineer's Guide to Digital Signal Processing by Steven
W. Smith available at dspguide.com.
Term: DTE
D ata T erminal E quipment. While the term has much wider meaning, in the
limited context of practical use with the CR6, it denotes the pin configuration,
gender, and function of an RS-232 port. The RS-232 port on the CR6 can be
configured as DCE or DTE, depending on the adapter used. Attachment of a
null-modem cable to a DCE device effectively converts it to a DTE device.

half-duplex, or full-duplex.
Reading list: simplex
(p. 601),
