neighbor device
Device in a PakBus network that communicates directly with a device without being routed
through an intermediate device.

Campbell Scientific software designed to help set up datal oggers in PakBus networks so
that they can communicate with each other and the LoggerNet server. For more

node
Devices in a network — usually a PakBus network. The communications server dials through,

by the same device (parent node) entered as child nodes. A node can be both a parent and a
child.
NSEC
Eight-byte data type divided up as four bytes of seconds since 1990 and four bytes of
nanoseconds into the second.
