4.5.3. Read version, device type or serial number, command „X“ (58h)
This command is for readout the version number, device type or serial number. The following sub-commands
are available:
Data = V (56h) = read version
Data = T (54h) = read device type
Data = S (53h) = read serial number
Example 1: Read version
SOH Adr Cmd Data EOT CRC
Transmission
01h 20h 58h 56h 04h D8h
SOH Adr Cmd Data Version number = 2.00 EOT CRC
Response
01h 20h 58h 56h 20h 32h 30h 30h 04h FAh
Example 2: Read device type (device type = 82h = N 142; software no. = 01)
SOH Adr Cmd Data EOT CRC
Transmission
01h 20h 58h 54h 04h DCh
SOH Adr Cmd Data Typ EOT CRC
Response
01h 20h 58h 54h 82h 81h 04h 6Eh
Code configuration of the transmitted device type:
1 0 0 0 0 0 1 0 1 0 0 0 0 0 0 1 = 82 81 hex
┬ ──────┬────── ┬ ───────┬─────
│ │ │ └─────── software no. 01h = program 01
│ │ └──────────────── permanent 1
│ └────────────────────────── device type 02h = N 142
└────────────────────────────────── permanent 1
Example 3: Read serial number
SOH Adr Cmd Data EOT CRC
Transmission
01h 20h 58h 53h 04h D2h
SOH Adr Cmd Data Serial number code = 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. Due to also the seconds being coded and by
assigning only one number per second the serial number is unique.
Example: Serial number for June 1 st , 2005 01.06.2005 16:58:36 = 15 83 0E A4 hex
