Example 3: Read serial number
SOH Adr Cmd Data EOT CRC
Transmission
01h 20h 58h
53h
04h D2h
SOH Adr Cmd Data Coded serial number = 07090EA4 EOT CRC
Response
01h 20h 58h 53h
30h 37h 30h 39h 30h 3Eh 3Ah 34h
04h 20h
Code configuration of the transmitted serial number:
The Low-Nibble (lower 4 bits of a byte) of the 8 data bits received equal together a 4 byte value comprising the
serial number.
The serial number is composed by date and time of production. Since also the seconds are coded and by as-
signing only one number per second the serial number is unique.
Example: Serial number for 01.06.2005 16:58:36 = 15 83 0E A4 hex
