15.3 Baud Rate
The Sunny Island 3324/4248 can communicate with external devices at a range of
different baud rates (1200 to 19200 bps). The "40-3 BaudRate" parameter must be
set appropriately for this.
The Sunny Island 3324/4248 uses the SMA-Net protocol for communication.
If Sunny Boys are connected to the communications bus, then the baud rate
must be set to 1200 bps (factory setting).
