FreeWave transceivers utilize a Master Transmit Beacon to provide low current consumption in the slave
radios. The slave radios will turn their receiver off when no data is being passed.
The Xmit Rate setting allows the duty cycle of the Master Transmit Beacon to be changed. A setting of 0
is the highest duty cycle and a setting of 9 is the lowest duty cycle.

The RF Data Rate controls the data rate used for over-the-air communication and should not be confused
with the serial port Baud Rate. Currently, the only supported RF Data Rate is 5.
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 Master will not establish a link.
In Point-to-Point networks the Master’s settings take precedence over the Slave.
