roving Gateway or Endpoint(s). As the link gets weaker, a lower setting allows
a poor link to break in search of a different link.
Note: FreeWave recommends setting the Retry Time Out to 20 in areas where
several FreeWave networks exist. This setting allows Endpoints and Repeaters
to drop the connection if the link becomes too weak, while at the same time
prevents errant disconnects due to interference from neighboring networks.
RF Data Rate
Note: In MultiPoint networks, the RF Data Rate must be set identically in all
transceivers. Any transceiver with an RF Data Rate different from the Gateway
will not establish a link.
In Point-to-Point networks, the Gateway’s settings take precedence over the
Endpoint.
Web Parameter: RF Data Rate in the Transmission Characteristics section of the Radio Setup
page.
Network Type: Both
Default Setting: 154 kbps
Options: 115 kbps, 154 kbps
Description: RF Data Rate should not be confused with the serial port Baud Rate. Use a
setting of 154 kbps when the transceivers are close together and data
throughput needs to be optimized. A setting of 154 kbps must also be used
when the full throughput of 92 kbps is necessary.
A setting of 115 kbps should be used when the transceivers are farther away
and a solid data link is preferred over data throughput.
The maximum available throughput in an FGR2-PE is:
l
≈70 kbps at an RF Data Rate of 115 kbps
l
≈92 kbps at an RF Data Rate of 154 kbps
Slave Attempts
Web Parameter: Slave Connect Odds in the MultiPoint Parameters section of the Radio
Setup page.
Network Type: MultiPoint
Default Setting: 9
Options: Any number between 1 and 15.
Description: This setting, in conjunction with the Slave Connect Odds parameter controls
how the Endpoint retries sending its data when it fails to receive a connection
acknowledgement from the Gateway. This setting is important in larger
networks to help manage contention over connecting to the Gateway. The
