Communication Reader-Host
3.7.13 GetSnrReset_LT
This command is applied to a HITAG 2 transponder which is currently not in Password or Crypto
Mode but in one of the Public Modes. The command selects the transponder and provides its
serial number and Configuration Byte.
If the byte -Status- shows „no error“ the transponder is selected and ready for read or write
accesses.
The byte -mode- decides whether the selection process for the transponder is done corresponding
to the Password Mode or the Crypto Mode.
C-Function: void proloc_GetSnrReset_LT (BYTE_T mode, DWORD_T *snr,

config:
n = 0 if an error occurred (error code in Status).
n = 5 if data were read from a transponder (Status = 0).
