4. GETTING STARTED
4.1 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 UMTS/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 ”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
Cable Interface 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 signal Strength LED ON and blinking.

Step 5 The Connected text in HyperTerminal status bar indicates that the PC is
ready to communicate with the modem. Perform a simple check on the connection
between HyperTerminal and the modem:
The following are some other AT command examples you can use:
AT Command Description
AT+CPIN? This command is used to send the ME a password
which is necessary before it can be operated
AT+CSQ This command is used to return received signal
strength indication
AT+CREG? This command is used to check on modem
registration to the network
AT+CGMR This command is used to query for modem firmware
version number
Enter AT<Enter> command.
An OK response

This section suggests examples for some basic functions using HyperTerminal
sending short messages (SMS):
Step 1 Set short message format as Text mode.
AT+CMGF=1 <Enter>
Step 2 Check whether SMS center (SMSC) number is set to SIM card.
AT+CSCA? <Enter>
Step 3 Send a message to a phone number.
AT+CMGS= “Phone number” <Enter>
>Hello <Ctrl-Z>
Step 4 Wait for +CMGS for the result of sending SMS.
+CMGS: <mr>
Indicates that the SMS has been sent successfully.

5. TROUBLESHOOTING
5.1 The modem is not power up
Check whether the LED Status (Green) 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 24VDC.
5.2 The SIM Card is not ready
Check whether the LED Status (Green) on and blinking. Check whether the
SIM Card to enabled.
Can use AT+CPIN? to request for PIN status. The status Ready is SIM Card
complete.
5.3 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
we 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.
5.4 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).
5.5 Cannot connect to WCDMA/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 WCDMA/GPRS Service. You can verify it with
the network service provider. If the SIM card supports WCDMA/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.
