Status flow
After entering the RF field the transponder waits for a
command to start the authentication (see Fig.2). After
issuing this command the mutual authentication takes
place, followed by read and write commands.
In the password mode the data transfer occurs plain and in
the crypto mode data are encrypted.
The halt state can be entered for muting a transponder.
If the transponder is configured in one of the public modes,
these modes are entered automatically after a certain
waiting time and data pages are sent cyclically to the read
and write device.
By issuing the command to start the authentication during
the waiting time also public mode transponders can be
brought into the authorized state.

Configuration
If you change the configuration (keys or passwords) you
have to place the transponder directly on the antenna
(0-distance)! In order to avoid any errors, do not move the
transponder during this write process and be sure that you
are in a safe environment without electrical noise.
The configuration byte is represented by the first 8 bits of
page 3 of the transponder memory (see Table 2).
