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.
Digi'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.
