The drawing below depicts a Multipoint Network in which the Subnet ID is used to
force communications along specific paths. In this example Repeater1 must talk
directly to the Master, and Repeater2 must talk directly to Repeater1.
Communications for Slaves 1, 2, and 3 are forced along the direction of the solid
lines, and Slave4 may link to the first Master or Repeater it hears.
The respective Subnet ID settings are shown in the table below.
Subnet ID Settings
Transceiver Rcv SubnetID Xmit SubnetID Notes
Master NA NA May be set to anything
Repeater1 0 1 0 forces it to link only to the Master
Repeater2 1 2 Rcv SubnetID=1 forces communication
through Repeater1 (Repeater1
transmits on SubnetID 1)
Slave1 0 NA Rcv SubnetID=0 forces communication
through the Master
Slave2 1 NA Rcv SubnetID=1 forces communication
through Repeater1
Slave3 2 NA Rcv SubnetID=2 forces communication
through Repeater2
Slave4 F F Setting of FF allows the Slave to link
with the first Master or Repeater it
hears with the correct NetworkID
Note: If you set the Rcv Subnet ID to '0', the modem (other than a master) will
communicate only with a master. If you set both Subnet IDs to 'FF', the
modem will communicate with any other modem in the same sub-network.
Other than that, you can set any value for these settings.
