3.3.11. GetSnr_HT2_P
This command selects a HITAG 2 transponder in Password Mode. With this selection the
transponder is prepared for read and write commands in HITAG 2 Password Mode.
For the selection in Password Mode, a password is transmitted to the reader module which must
correspond to Page 1 on the transponder (Password RWD). After the command has been exe-
cuted, the reader module returns the serial number and the content of Page 3 (configbyte with 24
Bit Password TAG).
When the transponder is in Crypto Mode, no selection occurs and only the serial number and the
status message "Password RWD error" are returned.
If the transponder is set in one of the public modes, it can only be selected within 2.56 ms after
reset (entering the RF field or activating the RF field).
