Section 8. Operation
8.5.4.2 Ping
Link integrity can be verified with the following procedure by using
PakBusGraph Ping Node. Nodes can be pinged with packets of 50, 100, 200, or
500 bytes.
Note Do not use packet sizes greater than 90 when pinging with 100 mW radio
modems and radio enabled dataloggers (see the appendix Telecommunications
Hardware ).
Pinging with ten repetitions of each packet size will characterize the link. Before
pinging, all other network traffic (scheduled data collections, clock checks, etc.)
should be temporarily disabled. Begin by pinging the first layer of links
(neighbors) from the PC / LoggerNet router, then proceed to nodes that are more
than one hop away. Table PakBus Link-Performance Gage (p. 356) provides a linkperformance
gage.
