FUNCTIONS
(1) Each station send range in B/W
Each station send range in B/W is set up with link parameters of the master station.
The following explains a link parameter setting example and send/receive ranges for
local modules.
(a) Link parameter setting example
Link parameters must be set to the master station for the second tier (M) and the
master station for the third tier (L2/m).
(b) Send/receive ranges when the local module is on the second-tier local station (L1)
1) L1 station writes data into the range of B/W100 to 1FF, and sends them to
other stations.
2) It can receive data written by other stations within the ranges of B/W0 to FF
and B/W200 to 37F.
