3.7.48 KeyInitMode
To be able to personalize the read/write device it is necessary to enter a special mode, the
KeyInit Mode.
The password (is different from Keys or Logdata) ensures that none but authorized persons are
able to enter the KeyInitMode.
ATTENTION: After the successful execution of this command (answer sent with Operating
Mode BCC calculation) the read/write device enters the KeyInit Mode and BCC
calculation changes.
The read/write device changes BCC calculation automatically. On the host system the user is
responsible for the new BCC calculation. The C-Library provides the function
proloc_SetBCCMode ( ).
C-Function: void proloc_KeyInitMode (DWORD_T password);
