Mod m Us
The SMC-GPRS modem is designed and intended for use in fixed and mobile applications.
“Fixed” assumes the device is physically secured at one location and not easily moved to
another location. Please eep the cellular antenna of the SMC-GPRS at a safe distance from
your head and body while the modem is in use (see below).
Important
Maintain a distance of at least 20 cm (8 inches) between the transmitter’s antenna and any
person while in use. This modem is designed for use in applications that observe the 20 cm
separation distance.
Int rf r nc Issu s
Avoid possible radio frequency (RF) interference by following these guidelines:
•The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may
endanger operation and disrupt the cellular networ . Failure to observe this
restriction may result in suspension or denial of cellular services to the offender,
legal action or both.
•Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been
approved and authorized.
•Do not operate in locations where medical equipment that the device could interfere
with may be in use.
•Do not operate in fuel depots, chemical plants, or blasting areas unless use has been
approved and authorized.
•Use care if operating in the vicinity of protected personal medical devices, i.e.,
hearing aids and pacema ers.
•Operation in the presence of other electronic equipment may cause interference if
equipment is incorrectly protected. Follow recommendations for installation from
equipment manufacturers.

Mobil Application Saf ty
•Do not change parameters or perform other maintenance of the SMC-GPRS while
driving.
•Road safety is crucial. Observe National Regulations for cellular telephones and
devices in vehicles.
•Avoid potential interference with vehicle electronics by correctly installing the
SMC-GPRS. CalAmp recommends installation by a professional.

This section describes the use of the SMC test board to set up the SMC modem for internet access
using HyperTerminal and a dial-up networ connection (DUN). Please refer to App ndix B for
details on setting up a modem driver for a DUN connection.
Conn cting Up th SMC T st Board
Connect the Power cable, RS232 cable, Antenna cable to the SMC test board as shown in Figure 5.1.
Insert an active SIM card into the SMC modem.
Figure 5.1 SMC test board connections
Hyp rT rminal S ttings
Open a HyperTerminal session and configure the properties for the COM port used to connect the
SMC test board.
Set HyperTerminal properties for:
Bits per second: 115200
Data bits: 8
Parity: Non
Stop bits: 1
Flow control: Hardwar

V rify SMC Mod m Conn ctivity
Power on the SMC test board (+12VDC typical) and observe the HyperTerminal window for
^SYSSTART , indicating the SMC modem successfully powered on.
Figure 5.2 HyperTerminal screen responses
The ATI command prints the cell module product information. If you get an Error or no
communication, verify the modem is connected to the proper COM port and powered on. Refer to
Figure 5.2 for all the AT commands listed below.
Confirm your SIM card is properly installed with the AT^SCID command. A reply of ^SCID:<20
digit CID number> indicates the modem recognizes the SIM card and displays it’s ID number.
Confirm the phone number currently in the modem with the AT+CNUM command. It should be 11
digits i.e. 18052162288. For some carriers the phone number may not display but will respond with
“OK”. If the SIM card is not in the unit or not activated properly, the modem will reply with “ERROR”.
Verify the modems International Mobile Equipment Identity (IMEI) number with the AT+CGSN
command. The IMEI is used to identify GSM mobile equipment to the GSM networ .

001-0004-829 Rev00
Page 16 of 84
Confirm that the SIM’s PIN has been authenticated by the networ using the AT+CPIN? command.
The reply should read “+CPIN: READY”. See Section 6 for SIM related information if “READY” does
not display.
Verify good signal strength with the AT+CSQ command. A typical reply is +CSQ 25, 99. The first
number is signal strength and ranges from 0 to 31 (the higher the number, the stronger the signal).
D fin th Pack t Data Protocol (PDP) Cont xt
Next, the Access Point Name (APN) must be defined using the PDP Context command
AT+CGDCONT=1,“IP”,<apn> command. The <apn> is the access point name for a specific
cellular provider (for example AT+CGDCONT=1,”IP”,internet). The At+CGDCONT? command can be
issued to verify the PDP Context information.
The PDP context information can be set to non-volatile by issuing the
AT^SCFG=GPRS/P rsist ntcont xts=1 command. GPRS PDP context will not be reset by an
AT&F command. Refer to Figure 5.3.

Conn ct using th Dial-Up-N twork Conn ction
Go to the Networ Connections screen and double clic on the newly created Dial-Up connection (i.e.
SMC-GPRS).
When the connect window appears, set the username and password as defined for your carrier
(usually blan ). Enter the phone number as *99***1# and clic the Dial button.

The modem will attempt to connect to the provider networ . If the configured baud rate for the COM
port, the modem, and the DUN do not match, the DUN will not be able to tal to the modem
properly and you will get a hardware error message. Otherwise the DUN will contact the cellular
networ and authenticate the user on the networ .
Once connected you should be able to browse the internet thorough the DUN session. To confirm
this, disable any other networ connections you may have running.

Right clic on the connected Dial-Up connection icon and select the Details tab. The status of the

The SIM card can be used to store a Personal Idetification Number (PIN) to authenticate users on
the networ .
The AT+CPIN write command can be used to enter one of the passwords listed below. The read
command can be used to chec whether or not the ME is waiting for a password, or which type of
password is required.
This may be for example the SIM PIN1 to register to the GSM networ , or the SIM PUK1 to replace a
disabled SIM PIN1 with a new one, or the PH-SIM PIN if the client has ta en precautions for
preventing damage in the event of loss or theft etc. If requested by the ME AT+CPIN may also be
used for the SIM PIN2 or SIM PUK2. If no PIN1 request is pending (for example if PIN1
authentication has been done and the same PIN1 is entered again) SMC modem responds "+CME
ERROR: operation not allowed"; no further action is required.
Each time a password is entered with AT+CPIN the module starts reading data from the SIM. The
duration of reading varies with the SIM card. This may cause a delay of several seconds before all
commands which need access to SIM data are effective.
AT+CPIN=<pin>[, <new pin>]
<pin>: Password (string type), usually SIM PIN1. If the requested password was a Pin Unloc Code
(PUK), such as SIM PUK1 or PH-FSIM PUK or another password, then <pin> must be followed by
<new pin>.
<new pin>: If the requested code was a PUK: specify a new password or restore the former disabled
password. See section “What to do if PIN or password authentication fails?” for more information
about when you may need to enter the PUK.
Successful PIN authentication only confirms that the entered PIN was recognized and correct. The
output of the result code OK does not necessarily imply that the mobile is registered to the desired
networ . Typical example: PIN was entered and accepted with OK, but the ME fails to register to the
networ . This may be due to missing networ coverage, denied networ access with currently used
SIM card, no valid roaming agreement between home networ and currently available operators etc.
The SMC modem offers various options to verify the present status of networ registration: For
example, the AT+COPS command indicates the currently used networ . With AT+CREG you can also
chec the current status and activate an unsolicited result code which appears whenever the status
of the networ registration changes (e.g. when the ME is powered up, or when the networ cell
changes).
The <pin> and <new pin> can also be entered in quotation mar s (e.g. "1234").
To chec the number of remaining attempts to enter the passwords use the AT^SPIC command.
See AT+CPWD and AT^SPWD for information on passwords.
See AT+CLCK and AT^SLCK for information on loc types.
