Slave / Repeater
Setting Description
Description
The Slave/Repeater mode allows a radio in a MultiPoint network to switch
between Slave and Repeater functions.
l When in this mode, a radio repeats any packets sent across the network as
well as uses the data port.
This allows one radio at one site.
l Thus, where one Repeater and one Slave may be required in another vendor’s
network, FreeWave networks require only one radio.
Note: To operate a radio as a MultiPoint Slave/Repeater, use the
Multipoint Parameters menu and set the operation mode to Multipoint
Repeater (7) and Slave/Repeater (1).
5.6.13. Subnet ID
In a Multipoint network, a Slave or Repeater connects with the first Repeater or Master it hears
with the same Network ID (on page 43).
Note: Subnet ID only works in Multipoint networks using the Network ID option.
Subnet ID is particularly helpful to force two Repeaters in the same network to operate in series
rather than in parallel or to force Slaves to communicate to a specific Repeater for load balancing
purposes. Two components exist with regard to the Subnet ID:
l Rx Subnet ID - This setting identifies the radio a Repeater or Slave listens to.
l Xmit Subnet ID - This setting identifies the ID the device transmits on and the devices
listening to it. The Xmit Subnet ID parameter is relevant for Multipoint masters and
repeaters only.
The default (disable) setting for both Rx and Xmit is F.
Important!: Changing these settings on the Master is NOT recommended under normal
circumstances.
In some Multipoint networks, the Frequency Key is at the same setting for all radios. In other
networks, where parallel Repeaters are used, the Frequency Key value needs to change.
l If both Rx Subnet ID and Xmit Subnet ID are set to 0 (zero), the Subnet ID shows
Roaming in the menu.
l This setting allows a mobile slave to roam from subnet to subnet and possibly from
network to network.
Figure 10 shows a network where Subnet IDs are used to force communications. In this
example:
l Repeater 1 must talk directly to the Master.
l Repeater 2 must talk directly to Repeater 1.
