ZDUE-GPRS-PLUS-VI
The ZDUE-GPRS-PLUS-VI is shipped with a predefined factory setting.
Depending on requirements, it may need to be reconfigured. This can be
done :
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
Among other things, the password protection, interface speeds, data formats
and the PIN that is to used can be parameterised.
For detailed information on parameterisation, see the chapter 6.
The PIN can be set
remotely via a CSD connection
locally via the RS-232 interface (if no active CSD connection is
present).
For detailed information on parameterisation, see the chapter , see the
chapter 6.
With SIM cards that have no PIN, the PIN query is skipped; the GSM
module does not wait for the PIN to be entered, but rather tries to check into
the GSM network directly.
If the PIN function of the SIM card being used is activated, and the PIN on
the SIM card being used agrees with the parameterised PIN, then the device
automatically tries to check into the GSM network.
If the PIN verification fails, it is repeated one time. If the repeated PIN
verification also fails, the device is blocked for further attempts (PIN ERROR
status), meaning that operation is no longer possible even with a SIM card
with the correct number. The Status/Error LED indicates a SIM/PIN error
(see 2)
This status is retained after the power supply is disconnected and
reconnected. This prevents the SIM card from being blocked if a third failed
attempt is made, after which it could only be unblocked using the PUK
(Personal Unblocking Key).
To unblock the ZDUE-GPRS-PLUS-VI, a SIM card with a deactivated PIN
function must be inserted in the device. After starting, the device attempts to
check into the GSM network, and the PIN ERROR status is also reset.
Alternatively, the ERROR status can be reset using the service command for
setting a new PIN (see 6.5.7). This simultaneously sets the PIN
parameterised in the device.
