IV.1 Serial link characteristics
The characteristics of the serial link to be used are as follows:

Protocol used: Modbus,
 Transmission speed: from 300 to 115200 bauds,
 Number of bits: 8,
 Parity: None,
 Number of stop bits: 1.
For FLOAT type information, it must be possible to read two consecutive words (or 4 bytes). The format
complies with the IEEE standard.
For LONG type information, two consecutive words (or 4 bytes) must be read.
