5 SMA Protocol
5.1 General
The Scale Manufacturers Association (SMA) protocol provides a simple access to the scale. Data could be
read and functions could be executed.
The RS-485 interface is used. The setting of the interface is fixed to 8 bit, no parity and 1 stop bit.
The scale commands are printable ASCII characters and start with a <LF> (0A hex) and end with a
<CR> (0D hex).
On each received command the transmitter sends after about 100ms an answer.
