Term: NAN
N
ot
a
n
umber. A data word indicating a measurement or processing error.
Voltage over-range, SDI-12 sensor error, and undefined mathematical results
can produce NAN. See the section
NAN and ±INF
(p. 466).
Term: neighbor device
Device in a PakBus network that communicate directly with a device without
being routed through an intermediate device. See
PakBus
(p. 508).
Term: NIST
National Institute of Standards and Technology
Term: node
Devices in a network — usually a PakBus network. The communication
server dials through, or communicates with, a node. Nodes are organized as
a hierarchy with all nodes accessed by the same device (parent node) entered
as child nodes. A node can be both a parent and a child. See
PakBus —
Overview
(p. 77).
Term: NSEC
Eight-byte data type divided up as four bytes of seconds since 1990 and four
bytes of nanoseconds into the second. See
Data Type
(p. 127)
tables.
Term: null-modem
A device, usually a multi-conductor cable, which converts an RS-232 port
from DCE to DTE or from DTE to DCE.
Term: Numeric Monitor
A digital monitor in
datalogger support software
(p. 86)
or in a
keyboard/display
(p. 80).
Term: offset
A term, often a parameter in a CRBasic measurement instruction, that
designates the y-intercept (aka, shifting factor or zeroing factor) in a linear
function. For example, when converting °C to °F, the equation is °F =
°C*1.8 + 32. The factor
32
is the offset. See
multiplier
(p. 505).
