3.10 Examples to Access HITAG 2 Transponders
3.10.1 Proximity/Long Range: READ
HT2_GetSnr Reads the serial number of a transponder in the communication
field of the antenna. There is a parameter in the C-Function
proloc_GetSnr_LT to specify whether you want to access a
transponder in Password Mode or in Crypto Mode. If the response
of the read/write device includes „no error“ the transponder is
selected and ready for read or write accesses.
HT2_ReadPage Reads a transponder.
Use C-Function proloc_ReadPage_LT.
HT2_HaltSelectedMutes the just treated transponder.
3.10.2 Proximity/Long Range: WRITE
HT2_GetSnr Reads the serial number of a transponder in the communication
field of the antenna. There is a parameter in the C-Function
proloc_GetSnr_LT to specify whether you want to access a
transponder in Password Mode or in Crypto Mode. If the response
of the read/write device includes „no error“ the transponder is
selected and ready for read or write accesses.
HT2_WritePage Writes to the transponder.
Use C-Function proloc_WritePage_LT.
HT2_ReadPage Reads from the transponder to verify if the write process was
successful. Use C-Function proloc_ReadPage_LT.
If the response of the read/write device (to this first command after
WritePage_LT) includes an error-condition, start from the
beginning of the Write-Sequence again!
HT2_HaltSelected
Mutes the just treated transponder.
