ADT60/AET60 Reference Manual version 1.5 November 2005
The following example shows the transmission of a command with instruction code A2
H
and one data byte
with the value 3D
H
. The command has the following structure:
byte 1 2 3 4 5

This command is transmitted on the serial interface in 12 bytes as follows:
byte 1 2 3 4 5 6 7 8 9 10 11 12
STX '0' '1' 'A' '2' '0' '1' '3' 'D' '9' 'F' ETX

For the representation of the hex half-byte values as the corresponding ASCII characters in commands, the
BioCARDKey/BioSIMKey accepts both upper case characters 'A' ... 'F' (41
H
... 46
H
) and lower case
characters 'a' ... 'f' (61
H
... 66
H
):
byte 1 2 3 4 5 6 7 8 9 10 11 12
STX '0' '1' 'A' '2' '0' '1' '3' 'D' '9' 'F' ETX
