RF401A-Series Spread Spectrum Radio

11.2.3 PakBus Verify Interval

This setting specifies the interval, in units of seconds, which will be reported as

the link verification interval in the PakBus® hello transaction message. It will

indirectly govern the rate at which the device will attempt to start a hello

transaction with a neighbor if no other communication has taken place within

the negotiated PakBus® link verification interval. When

Active Interface is

PakBus Router, hello transactions will occur over RF; otherwise, they will be

sent over the serial port selected as the

Active Interface.

If

PakBus Verify Interval is set to zero, a verify interval of 2.5 times the

PakBus Beacon Interval will be reported by the device.

It is advised that

PakBus Verify Interval be set to an interval

several times larger than your expected general communication

interval, for example, data collection interval.

11.2.4 Central Router

Specifies the PakBus® address of another device that the RF401A series will

use as a

Central Router. A valid setting is a single address between 1 and

4094. When set, the RF401A series will act as a branch router. Specifying a

central router address can reduce the amount of PakBus® RF traffic by

eliminating the exchange of neighbor lists with routers beyond the central

router. This is especially true when the network contains many transient or

intermittent PakBus® routers. If the RF401A series does not know how to

explicitly route a packet, it will be handed off to the

Central Router specified

by this setting.

11.2.5 Neighbors Allowed

This setting specifies an explicit list of nodes the RF401A series will accept as

neighbors when acting in the capacity of a PakBus® RF repeater / router. If

the list is empty (default), any node will be accepted as a neighbor. This

setting will not affect the acceptance of a neighbor if that node’s address is

greater than 3999. The formal syntax for this setting is:

neighbor := { "(" range-begin "," range-end ")" }.

range-begin := pakbus-address. ;

range-end := pakbus-address.

pakbus-address := number. ; 0 < number < 4000

Example: (129,129) (1084, 1084)

In the example above, nodes 129 and 1084 are assigned as neighbors to the

RF401A series.
