Referencing the default settings, the Master will transmit up to 172 bytes on every hop. If fewer than 172
bytes are transmitted, the balance is allocated to the Slave's transmission, plus the quantity in the Min
Packet Size Setting.

For example, if a Master transmits 100 bytes, the Slave will then have a total of 116 bytes available

There are two settings for the Transmit Rate parameter. The setting for normal operation of the
transceiver is a Transmit Rate 1. Transmit Rate 0 is useful to qualitatively gauge signal strength in Point
to Point mode. When set to Transmit Rate 0, the transceivers will transmit back and forth continuously
regardless if they have any actual data. In Point-to-Point operation, Transmit Rate 0 should be used only
as a diagnostic tool and not for normal operation. The strength of the signal may be gauged by the Clear
