StAdrH Start address. Address of the first relevant byte in read/write mode.
The syntax and length of this command differs according to the type
of data carrier. Addressing is carried out byte by byte.
BytesH Number of corresponding bytes in read/write mode in hexadecimal
notation, 2 ASCII characters
(01 ... 20-StAdrHr) for IDC- ... (Max. 32 bytes)
(01 ... 80-StAdrH) for IDC- ... -1K and IMC-40- ... (Max. 128 bytes).
DB Binary representation of data. The number of characters transmit-
ted depends on the command.
32DB 32 data bytes in binary format.
CHCK Check sum for the data transmission (binary, 1 byte). The sum of all
transmitted characters ignoring any carry-over.
Status Status or error message in read/write mode, 2 ASCII characters
