serial_number
Here the serial number of the hardware is read. The first two characters of the
serial number are letters which designate the manufacturing lot. The following
characters represent the actual serial number.
In the two MSB of serial_no the letters of the manufacturing lot are coded. They
each contain the ASCII-code of the letter with the MSB set ‘1’ in order to be able
to differentiate between letters and numbers:
(ASCII-Code) + 80
h
= read_byte
The two last significant bytes contain the number of the module as BCD-value.
Example:
If the value ‘C1C2 0105
h
’ is being read, this corresponds to the hardware-serial
number code ‘AB 0105’. This value has to correspond to the serial number of the
module.
