4.2. *ENABLING THE UNIT ON GSM AND GPRS
required: The SIM card’s user PIN and the cellular operator APN (Access
Point Name).
4.2.1 SIM Card’s PIN for GSM registration
This parameter is optional because it depends on how the SIM card is con-
figured. Most cellular operators distribute no-pin SIM cards so you don’t
have to worry about this parameter or you can explicitly set it to “empty”
if you are unsure of a previous configuration
4
. But if your SIM card requires
a PIN this parameters has to be set or else the unit will fail to register on
GSM. The configuration message for the SIM card’s PIN is the
RF
message.
You can check the TAIP reference for more information but the command’s
use is as follows:
To set the PIN number
1234
send to the unit:
>
SRFI1234
<
To set an “empty” PIN:
>
SRFI
<
Use the
Q
qualifier to consult.
A PIN configuration can be issued at any time but although the registra-
tion process is always done automatically, the unit will take up some time on
registering to the GSM network when a previous erroneous PIN was given
or when no PIN was not given. So it is recommended in those cases to reset
the unit after the PIN-set command with the
>
SRT
< reset message. Or
better, have the PIN correctly configured before the SIM card is inserted.
The Antares SB
TM
does not block a SIM card when the given PIN
is wrong.
Note:
The GSM registration status can be consulted with the
RP
message and/or
with the Signal led. For more information consult the TAIP reference and
the Leds subsection on the Operation chapter.
When the unit is GSM-registered it is able to make or receive telephone
calls and 2-way SMS communication.
The PIN parameter can not be changed over the air. This to
prevent the unit from loosing the GSM/GPRS network when an
incorrect PIN is tried remotely. The PIN value can only be mod-
ified over the serial port.
Note:

Any PIN value will work when using a no-PIN SIM card
