ER400RS Receiver
The Easy-Radio 400 Receiver is a complete sub-system that combines a high performance low power RF
receiver, a ‘flash’ programmable microcontroller and a voltage regulator (Figure 3). The microcontroller
programmes the functions of the RF receiver and provides the interface to the host system via a data output.
It also contains programmable EEPROM memory that holds configuration data for the various receiver
operating modes. The microcontroller also relieves the host from the intensive demands of searching for
signals within the noise, recovering the received data and then presenting it to the host. A Received Signal
Strength Indicator output can be optionally used to measure received signal levels. The module connects to
a 50 Ohm antenna such as a whip, helical or PCB loop.
The ER400RS will receive and decode any Easy-Radio transmission within range and on the same
frequency and deliver clean data to the host system for further processing.
The Serial Data Output operates at programmable standard Baud Rates (default/typical 19,200Baud).
Key parameters (frequency, power output, serial baud rate etc.) of the module may be programmed using
the Easy-Radio PC Software via SDI pin 6. (See page 12 for Easy Radio Configuration Command Set.)
