If both Rcv Subnet ID and Xmt Subnet ID are set to 0 the Subnet ID will show Roaming in the
menu. This setting will allow a mobile Slave to roam from subnet to subnet and possibly from
network to network.

This drawing depicts a Network in which Subnet ID’s are used to force communications. In this example,
Repeater1 must talk directly to the Master; Repeater2 must talk directly to Repeater1. Slaves 1, 2, and 3
are forced along the direction of the solid lines. Slave4 may link to the first Master or Repeater it hears.

Note: With firmware x.40 and above, the Subnet ID default is F,F. A Multipoint Master with an F,F
Subnet ID will behave the same as if the Subnet ID was set to 0,0. A Multipoint Slave with a
Subnet ID of F,F will not roam from one repeater or network to the next, it will only link to a
Master or Repeater that has either a Transmit Subnet of 0 or an F,F Subnet ID.
