4.5.3. Read version or serial number „X“ (58h)
This command reads out version number, device type or serial number. The following sub-commands are avail-
able:
Data = V (56h) = read out version number
Data = T (54h) = read out device type
Data = S (53h) = read out serial number

Structure of the encoded serial number transmitted:
The Low-Nibble (lower 4 bits of a byte) of the 8 data bytes received equal a 4-byte value encoding the serial
number.
The serial number is composed of production date and time. Since the seconds come encoded as well and per
second only one number will be allocated, the serial number is unique and unambiguous.
Example: serial number for production date and time 01.06.2005 16:58:36 = 15 83 0E A4 hex
