10. Command the M20T to cut the line whenever the DTR signal is dropped
(OFF) or toggled ON/OFF: AT&D2
11. Store setting in non-volatile memory: AT&W.
12. You may now enter the PIN number or let the Excel CPU do this. If you want
to enter the PIN number now, enter the PIN with the command
AT+CPIN="xxxx", where xxxx represents the PIN number.
NOTE: Regarding the PIN entry, the M20T shows the same behavior as a regular
cellular phone, as it uses the same type of SIM card. This means, for
example, that after three false PIN inputs, the SIM card will lock and need
to be released via the "PUK" Personal Unlocking Key (Master PIN).
Repeated input of the wrong "PUK" (more than two false inputs) will destroy
the SIM card irrevocably.
13. Once the M20 has accepted the PIN it will log into the GSM net.
The terminal window will show "OK".
The M20T LED will be on continuously.
14. Disconnect the serial cable from the PC/laptop and connect it to the Excel
CPU.
15. Verify that the M20T dials out on the telephone number for data communi-
cation, otherwise its call will not be recognized by the XBS.
The M20T can be forced to do so by adding the letter <i> to the telephone
number, e.g.<ATDi1234567891234>
NOTE: As soon as the PIN is entered into the Excel controller, the following
mechanisms will take place automatically:
— Cyclical check (once per minute) for existence of the PIN number in the
M20 (AT+CPIN?)
— Sending of PIN number to M20T if it has lost it.
This guarantees communication will resume automatically after
exchange of the SIM card or after power to the M20T has been lost.
Deletion of the PIN number or resetting the controller will stop the above
mechanisms.
Verification of the PIN
You can verify the PIN without connecting a terminal program by following these
steps:
1. Connect the XI582 MMI.
2. Enter PIN.
3. Disconnect the XI582 MMI.
4. Connect the M20T and wait 10 seconds.
5. Reconnect the XI582 MMI.
6. View the "PIN" field.
7. If it shows "0", the PIN was wrong.
8. If it shows "PIN", the PIN was correct.
