3.7 Command Description for Operating Mode
The Operating Mode is a mode of the reader for using a set of standard commands as described in
the following.
In this mode the BCC is computed by EXOR-operation of all block data bytes including Block
Length.
The command KeyInitMode is used to enter the KeyInit Mode (mode of the read/write device for
using personalization commands), and a different set of commands becomes available.
3.7.1 GetSnr
This command provides the serial number of a HITAG 1 transponder in Standard Protocol Mode.
For further information on the Standard Protocol Mode see chapter „Transponders“.
C-Function: void proloc_GetSnr (DWORD_T *snr, BYTE_T *more);
Header-File: PROLIB6.H
Serial protocol:
HOST - READ/WRITE DEVICE
