Section 8. Operation 8.5.4.2 Ping (PakBus) 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 Data Retrieval and Telecommunication - Peripherals Lists (p. 601). 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. 400) provides a linkperformance gage. Table 103. PakBus Link-Performance Gage 500 byte Pings Sent Successes Link Status 10 10 excellent 10 9 good 10 7-8 adequate 10
