PIN in Terminal Mode
Entering the PIN
If LED S blinks slowly (once per second), the
TO-PASS
®
modem GRPS RS-232
is waiting for the PIN to be entered.
In GPRS mode, the PIN is passed by the connected PLC to the
TO-PASS
®
modem GRPS RS-232.
The PIN must be entered in the data block of the PLC program. Check the
connection between the PLC and the
TO-PASS
®
modem GRPS RS-232.
LED S (Status) is blinking fast
If LED S is blinking fast (4 times per second):
•
The SIM card was either not recognized, or
•
The SIM card was PUK blocked because the wrong PIN was entered too
many times.

Make sure that the SIM card has been correctly inserted in the device (see
"Inserting the SIM Card").
2
Check whether the SIM card is SIM blocked. Insert the SIM card into a
normal cellular telephone. The telephone will display whether the SIM card
is PUK blocked. If the SIM card is PUK blocked, enter the PUK and then a
PIN. Ideally, use a cellular phone.

Before inserting the SIM card into the
TO-PASS
®
modem GRPS RS-232
again, identify why the SIM card was PUK blocked: What PIN is in the
PLC program?

Check and if necessary, delete the parameter SIMSTATE of the
TO-PASS
®
modem GRPS RS-232.
