router
A device configured as a router is able to forward PakBus packets from one port to
another. To perform its routing duties, a data logger configured as a router maintains its
own list of neighbors and sends this list to other routers in the PakBus network. It also
obtains and receives neighbor lists from other routers. Routers maintain a routing table,
which is a list of known nodes and routes. A router will only accept and forward packets
that are destined for known devices. Routers pass their lists of known neighbors to other
routers to build the network routing system.
RS-232
Recommended Standard 232. A loose standard defining how two computing devices can
communicate with each other. The implementation of RS-232 in Campbell Scientific data
loggers to computer communications is quite rigid, but transparent to most users.
Features in the data logger that implement RS-232 communication with smart sensors are
flexible.
RS-422
Communications protocol similar to RS-485. Most RS-422 sensors will work with RS-485
protocol.
RS-485
Recommended Standard 485. A standard defining how two computing devices can com-
municate with each other.
RTDAQ
Real Time Data Acquisition software for high-speed data acquisition applications. RTDAQ
supports a variety of telecommunication options, manual data collection, and extensive
data display. It includes Short Cut for creating data logger programs, as well as full-fea-
tured program editors.
RTU
Remote Telemetry Units
