Section 14. PakBus Networking
14-28
Radio Address
RF4xx Radio Address. In transparent PakBus networks
all RF4xxs are configured to the same radio address. In
a PakBus Aware or PakBus Mode network, the Radio
Address is not used.
Represented
Refers to a device that is shown in the LoggerNet
device map. Some communication devices, such as the
RF4xx, need not be represented in the device map.
RF
Radio frequency. Having to do with wireless radio
transmission and reception.
Route
A communication path to a node. There can be multiple
hops to the destination node.
Router
A PakBus device that is configured to accept packets
destined for another device and pass them along toward
that device. A router only accepts packets destined for
PakBus addresses for which it has a route. Examples of
possible routers are: the CR800, the CR23X with
PakBus OS, the NL100, a stand-alone RF401 router,
and LoggerNet. A device may be capable of being a
router but not configured as such. CR2xx devices
cannot act as routers.
Routing Table
A router’s list of routes (neighbors leading to
destinations) to every PakBus device of which it is
aware in the network. A routing table is created using
the best-route algorithm working with the neighbor lists
passed among network routers.
SDC
Synchronous Device Communications – clocked serial
communications between datalogger and an addressed
peripheral. A datalogger peripheral that is enabled by
addressing rather than by asserting the modem enabled
line.
Server
In client-server architecture, a computer or device on a
network that manages (gives access to) network
resources. In PakBus networking LoggerNet’s server
has a router or routers and communicates with other
PakBus devices via its PakBus Interface. It
communicates via transactions on the LoggerNet
Interface with clients such as PakBusGraph and
ConnectScreen.
Static Link
A route or link that exists by virtue of a LoggerNet
Setup device map or a program instruction. Dynamic
routes are those that have been proven to work (and are
current in terms of their communications verification
interval). In PakBusGraph a static link is colored red
until proven at which time it turns black.
