3704043552 - 07/2017 Terminal 97 00
4.4.5 Operating states
4.4.5.1 Online
After a booking, the terminal carries out the parametrized tests and enters the test result in
the registration data record as error detection. The registration data record is transmitted to
the host. Following this, the terminal expects a logical booking response from the host. Along
with it, the host communicates to the terminal the decision whether or not the booking is au-
thorized.
If the terminal does not receive a logical booking response from the host, it will switch to the
offline operating state and decide itself based on the parametrized tests whether the booking
is authorized. As soon as the host can be reached again, all data records saved in the mean-
time in offline will be transmitted to the host. Then the terminal automatically switches again
to the online operating state.
4.4.5.2 Offline
After a booking, the terminal carries out the parametrized tests and decides immediately
whether or not the booking was authorized by sending an internal booking response. Depend-
ing on the parametrization, registration records are stored in the terminal. As soon as the
host can be reached, all data records saved since the last transmission will be transmitted to
the host.
4.4.5.3 Autonomous
After a booking, the terminal carries out the parametrized tests and decides immediately
whether or not the booking was authorized by sending an internal booking response. Depend-
ing on the parametrization, registration records of authorized and unauthorized bookings are
stored in the terminal.
If the host can be reached, any error and alarm records that may be available will be trans-
mitted to the host.
The saved registration data records are transmitted to the host on request together with a
special data record.
4.4.6 Devices with biometric reader
Biometric software
When communicating via B-COMM, the program package B-COMM - Biometrics option is re-
quired for managing and distributing the finger templates.
Communication with the Finger Template Control Service (FTCS) of the biometrics software
takes place via Ethernet/UDP and a separate channel.
When connected to HTTP/HTTPS-based applications, the distribution of the finger templates
also takes place via the HTTP/HTTPS host channel.
Standalone mode
Alternatively, operation without a biometric host is also possible. In this ‘Standalone mode’, all
fingerprints of persons must be registered by the reader of the terminal. In this case, the fin-
ger templates are only saved in the reader’s internal database. If they get lost, all persons
have to be registered again at the terminal.
This is why the Standalone mode without biometric software is only recommended for very
small solutions (max. 20 persons).
