Configuration
The configuration of the SmartALPHA module may be changed by placing the SmartALPHA in Configuration
mode, then sending a set of configuration data bytes to the module on the Tx pin.
To place the SmartALPHA in Configuration mode the user needs to send “+++” (three plus characters) within
the 10mS timeout for each character. The SmartALPHA responds be returning the Configuration data bytes.
The SmartALPHA is now on Configuration mode.
To exit Configuration mode the user needs to send “---“ (three minus characters) within the 10mS timeout for
each character. The SmartALPHA will not return a response. The SmartALPHA is now in data mode.

The RF Channel is calculated as:
433 MHz working frequency: Config value (decimal) = ((Fo/10)-43)*4000
868 MHz working frequency: Config value (decimal) = ((Fo/20)-43)*4000
915 MHz working frequency: Config value (decimal) = ((Fo/30)-30)*4000
(Fo = Required Frequency)
Please Note, the calculated value must be converted into binary. The high byte is placed in byte 8 and
the low byte in byte 9. The Config value MUST be in the range 96 to 3903 (decimal). Both bytes must be
present for the channel to be accepted.
While the SmartALPHA is in configuration mode, then the module will send the current configuration
back to the host each time a data packet is received. To retrieve the current configuration without
changing any options the host can send a single byte to the module and wait for the response.
It is not necessary to send all configuration bytes to the module, but all data sent must be valid. For example to
change the destination address the host may just send four bytes. Configuration data excluded from the end of
the data stream will be unchanged. The SmartALPHA module will accept a short configuration after a 10ms
