CR1000 Manual - Campbell Scientific

Appendix B. Status Table and Settings
Table 122. CR1000 Settings
Settings are accessed through the Campbell Scientific Device Configuration Utility (DevConfig) via direct-serial and IP connections, or through
PakBusGraph via most CR1000 supported telecommunications options.

This setting specifies, for a given port, the explicit list of PakBus® node addresses that
the CR1000 will accept as neighbors. If the list is empty (the default condition), any
node is accepted as a neighbor. This setting will not effect the acceptance of a neighbor
if that neighbor's address is greater than 3999. The formal syntax for this setting
follows:
neighbor := { "(" range-begin "," range-end ")" }.
range-begin := pakbus-address. ;
range-end := pakbus-address.
pakbus-address := number. ; 0 < number < 4000
If more than 10 neighbors are in the allowed list and the beacon interval is 0, the beacon
interval is changed to 60 seconds and beaconing is used for neighbor discovery instead
of directed hello requests that consume comms memory.
Central Routers
This setting specifies a list of up to eight PakBus ® addresses for routers that are able to
work as central routers. By specifying a non-empty list for this setting, the CR1000 is
configured as a branch router meaning that it will not be required to keep track of
neighbors of any routers except those in its own branch. Configured in this fashion, the
CR1000 will ignore any neighbor lists received from addresses in the central routers
setting and will forward any messages that it receives to the nearest default router if it
does not have the destination address for those messages in its routing table.
Each entry in this list is expected to be formatted with a comma separating individual
values.
