PRELIMINARY
Data Format
The module acquires the analog signal value of each channel and converts it in
a digital string (bit). Each analog signal is converted in a 16 bit word which is
serially transmitted as before described.
Then, it is possible to convert the received string in the corresponding decimal
value, considering that each value is expressed in signed integer (the most
significant bit indicates the sign: 0=positive 1=negative).
The user will must insert the decimal point as illustrated in the following tables.
