An RF data link between two modules.
Use default values for all modules.
All modules:
Streaming, Multi-Transmit, Repeater

RF modules remain synchronized without use of master/server
dependencies. Each module shares the roles of master and slave.
MaxStream's peer-to-peer architecture features fast synch times
(35ms to synchronize modules) and fast cold start times (50ms
before transmission).
Use default values for all modules.
