10.4.74.22 RadioRetryTimeout
Setting RadioRetryTimeout in a Slave or Repeater sets the delay the unit will wait before
dropping the connection to a Master or Repeater in MultiPoint mode. This setting is useful when
a MultiPoint network has a roving Master or Slave(s). As the link gets weaker, a lower setting will
allow a poor link to break in search of a stronger one.
The factory default is set at the maximum of 255. With a setting of 255, the Master will allow a
Slave or Repeater to stay connected as long as 1 packet in 255 is successfully received at the
Master. The minimum setting is 8. This allows a Slave or Repeater to drop a connection if less
than 1 in 8 consecutive packets is successfully received from the Master.
Setting RadioRetryTimeout to 20 is recommended in areas where several FreeWave networks
exist. This setting will allow Slaves and Repeaters to drop the connection if the link becomes too
weak, while at the same time preventing errant disconnects due to interference from neighboring
networks. While intended primarily for MultiPoint networks, the RadioRetryTimeout setting may
also be modified in Point-to-Point networks. However, the value in Point-to-Point mode should
not be set to less than 151.

10.4.74.23 RadioRxSubID
In a MultiPoint Network (with Subnet IDs disabled), a Slave or Repeater will connect with the first
Repeater or Master that it hears with the same Network ID. There are scenarios, however, where
communications need to be forced to follow a specific path. The Subnet ID is particularly helpful
to force two Repeaters in the same network to operate in series rather than in parallel; or, if
desired, to force Slaves to communicate to a specific Repeater for load balancing purposes.
There are two components to the Subnet ID:
1. Receive Subnet ID (RX ID): This setting identifies which transceiver a Repeater or Slave will
listen to. The RX ID has no effect on a radio configured as Master and should be left at the
default value of 15.
