10 STATE DIAGRAM
10.1
Power Off
The powering magnetic field is switched off or the
HITAG S Transponder is out of field.
Ready
After start up phase, the HITAG S Transponder is ready to
receive the first command.
Init
The HITAG S Transponder enters this State after the first
UID REQUEST xx command. In this State the Response
Protocol Mode (see Chapter11 “Command Set”) may be
changed by further UID REQUEST xx commands. If there
are several HITAG S Transponders in the field of the RWD
antenna at the same time, the AC SEQUENCE can be
started to determine the UID of every HITAG S
Transponder.
Authenticate
The HITAG S Transponder enters this State after a valid
SELECT (UID) command when configured in
Authentication Mode. After an encrypted CHALLENGE
Authentication the HITAG S Transponder changes into the
Selected State.
Selected
The HITAG S Transponder enters this State after a valid
SELECT (UID) command when configured in Plain Mode
or a SELECT (UID) and CHALLENGE sequence when
configured in Authentication Mode. Only one HITAG S
Transponder in the field of the RWD antenna can be
Selected at the same time. In this State, Read and Write
operations are possible. Data Transmission is not
encrypted even if configured in Authentication Mode.
Quiet
The HITAG S Transponder enters this State after a
SELECT_QUIET command in Init State or a QUIET
command in Selected State. In this State, the HITAG S
Transponder will not answer to any command. Switching
off the powering magnetic field or moving the HITAG S
Transponder out of field enters it into the Power Off State.

Transponder Talks First (TTF)
The HITAG S Transponder enters this State when
configured in TTF Mode if no UID REQUEST xx command
is received within the Mode switch window. Once entered
this State, the HITAG S Transponder continuously
transmits data with configurable data coding, data rate and
data length.
