53
6.4 Automatic Logout and Login or Restart of the Device
Scheduled logout/login or a device restart can be activated using
the HSComm. Click on the “GSM/GPRS” tab.
6.4.1 Automatic Login at Restart
The INSYS GPRS 5.1 serial can store the SIM card PIN internal-
ly, which enables it to log into the GSM network after each
restart and reset, without user intervention.
All four globally used frequency ranges 850 MHz, 900 MHz,
1800 MHz and 1900 MHz are supported. At the respective lo-
cation, the INSYS GPRS 5.1 serial will automatically operate
with the frequency range provided by the network provider.
AT**PIN=<pin>
Before using the INSYS GPRS 5.1 serial, you should
check the certification requirements in the country of
deployment.
Note: As default, the INSYS GPRS 5.1 serial will login to
the strongest available GSM network. If required,
a preferred network can be pre-selected with the
command
AT**PROVIDER , if necessary.

6.4.2 Periodic Logout and Login or Restart of the Device
For function support even after infrastructure changes and net-
work software updates by the network providers, the INSYS GPRS
5.1 serial can be logged out of the GSM network via a timer. The
timer can be set by the hour up to a maximum of 99 hours and
starts when the device is switched on. A few minutes after the
module logged out it will automatically log back in. The timer re-
starts.
If a TCP transparent or a data connection (CSD or GPRS) is estab-
lished at the time of the logout, the logout will wait until the
connection is terminated.
As an option, there is also the possibility to perform a complete
restart of the device after the timer has expired. The INSYS GPRS
5.1 serial will start automatically with the stored settings.
