GETTING STARTED
Setting up the modem
Step 1: Prepare the SIM Card.
Before using the modem, you must contact a network operator to get a personal SIM card. Do acquire the
GPRS APN, User-ID and Password from your network operator.
Step 2: Insert SIM card into the modem.
Please refer to Chapter 3.6 “SIM Interface” for more detailed information.
Step 3: Connect the antenna to the modem.
Please refer to Chapter 3.7 ”GSM Antenna Interface” for more detailed information.
Step 4: Connect the modem communication interface to your device.
Connect the modem serial link interface (Pin #2 to Pin #8) to your device. Please refer to Chapter 3.3 “Serial
Link Interface Cable” for more detailed information.
Step 5: Power up the modem.
Connect Pin #1 and Pin #4 of the interface cable RJ-45 plug to the input voltage and ground respectively. The
status indicator LED will light up instantly. The modem is now ready to use.
Step 6: Communicate with the modem.
The modem is now ready to communicate with your device. From your device, send AT<Enter> command to
modem. If device received an OK response from modem, the communication is successfully established.
The following are some other AT command examples you can use:
AT Command
Description
AT+CPIN?
To check whether SIM Lock is enabled
AT+CPIN=xxxx
To enter a PIN code if SIM lock is enabled
AT+CSQ
To query and verify the current received signal strength
AT+CREG?
To check on modem registration to the network
AT+CGMR
To query for modem firmware version number
Please refer to the iTegno 39XX AT Commands Guide for more information on communicating with the modem
using AT Commands.

TROUBLESHOOTING
This section suggests the possible solutions for common problems encountered when using the iTegno 39XX
GPRS modem.
5.1
Is my modem powered up?
 Check whether the LED on the modem is lighted up. If it is not lighted up, check whether the modem is
supplied with the correct voltage range (between 5V to 32VDC).
5.2
Is my SIM card SIM Lock enabled?
 Use AT+CPIN? to request for PIN Status, or
 AT+CLCK=”SC”,0,”password” to disable SIM LOCK.
5.3
What is my SIM card PIN code?
If you have forgotten or lost your PIN code, or, you have not received such a code, please contact your
network service provider for assistance.
5.4
Unable to register to the network
 Check the modem status indicator. The LED should be blinking if the modem is registered to the network.
 Use AT+CREG? command to request for the registration status.
 Check the signal strength of the network using AT+CSQ command. You should receive a +CSQ response
(+CSQ: <rssi>, <ber>). If the rssi value is 99, it means the network is unknown or undetectable. The ideal rssi
value should be 8 to 31. An rssi value less than 8 has weaker signal strength.
5.5
Cannot enter AT Commands or no communication between device and modem
 Check whether the modem is powered up.
 Check whether the SIM Lock is turned on.
 Check whether the communication interface port is connected properly.

 Check whether the port settings are correct. Ensure that both modem and your device are communicating
with the same settings (such as baud rate, data bits, stop bits and parity). Note that the modem default port
settings are:

Hardware
 Try isolating your device by connecting the modem to a Windows-based PC with HyperTerminal and test the
communication between the modem and PC. Please refer to Chapter 4.2 “Interfacing Modem with
HyperTerminal Software” for the setup instructions.
5.6
Cannot send SMS using AT+CMGS command
 Check whether the modem is powered up.
 Check whether the SIM Lock is turned on.
 Check whether the modem is registered to the network.
 Try putting the SIM card into a mobile phone and/or another modem to send an SMS. If the SMS cannot be
sent, check with your network service provider on the status of the SIM card.
 Verify that the SMS Service Centre Number is correct using the AT+CSCA? command.
 Ensure that the modem is set to text message mode. You may do so using AT+CMGF=1 command. Please
refer to Chapter 4.2.2 “Sending Short Messages (SMS)” for more details.
5.7
Cannot connect to GPRS
 Check whether the modem is powered up.
 Check whether the SIM Lock is turned on.
 Check whether the modem is registered to the network.
 Check whether the SIM card supports GPRS Service. You can verify it with the network service provider. If
the SIM card supports GPRS service, check whether the APN settings are correct. Use AT+CGDCONT?
command to query or assign the APN settings. Ensure that it is correct by confirming the APN with your
network service provider.
