modem/terminal
Any device which:
•
has the ability to raise the CR200(X) ring line and put the CR200(X) in
the Telecommunications Command State
•
has an asynchronous serial communication port which can be
configured to communicate with the CR200(X).
multi-meter
An inexpensive and readily available device useful in troubleshooting data
acquisition system faults.
mV
The SI abbreviation for milliVolts.
NAN
Not a number. A data word indicating a measurement or processing error.
Voltage over range, SDI-12 sensor error, and undefined mathematical
results can produce NAN.
Neighbor Device
Devices in a PakBus® network that can communicate directly with an
individual device without being routed through an intermediate device. See
PakBus
(Appendix p. 7).
NIST
National Institute of Standards and Technology
Node
Part of the description of a datalogger network when using LoggerNet.
Each node represents a device that the communications server will dial
through or communicate with individually. 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.
Null-modem
A device, usually a multi-conductor cable, which converts an RS-232 port
from DCE to DTE or from DTE to DCE.
Ohm
The unit of resistance. Symbol is the Greek letter Omega (
Ω
). 1.0
Ω
equals
the ratio of 1.0 Volt divided by 1.0 Amp.
