Frequency Hopping Spread Spectrum
A FHSS radio does just what its name implies – that is, it ‘hops’ from frequency to frequency over a wide band. The
specific order in which frequencies are occupied is fixed but in a pseudo random order.
Modes of Operation
The Radio
RM8003-03
has 4 operating functions:
Transmit serial data
Receive serial data
Hardware IO control
Hardware Beacon outputs
Hardware IO mode acts like a one to many remote controls so when Digital input one on any device is activated,
the radio broadcasts this information to all other radios on a synchronized beacon. When a remote device receives
information that one of the other radios Digital Input 1 has been activated, it activates its Digital Output 1.
Hardware Beacon outputs are configurable at the factory to output a beacon pulse on Digital Output 2 in any 1
second period increment. The Fundamental System Timekeeper generates the timing for this pulse and keeps
Listener radios updated as to the status of this Hardware Beacon Pulse.
Serial Data Received on any radio will be directed to the remote radio device that is getting addressed by the host
application.
Local Serial Data received for device configuration will not be transmitted on the RF network.
