2.41 MODEM QuickStart

To set up the modem, do the following:

Press SIM card holder ejector (yellow button) with a sharp object (the tip of a pen for example).

Insert the SIM card in the holder. Verify the SIM card fits in the holder properly.

Connect the antenna to the SMA connector. Connect both sides of the serial and control cable Connect the power adaptor to the power supply, and plug into the Modem. Now the modem is ready to work. Refer to Chapter 3 for some AT commands

to configure the modem.

2.42 Checking the communication with themodem

Connect the RS232 link between the DTE (port COM) and the modem(DCE). Configure the RS232 port of the DTE as follows:

Bits per second: 115200 bps or 9600 bps Data bits: 8 Parity: None None Stop bits: 1 Flow control: Hardware Flow control control.

Using a communication software such as Hyperterminal program, enter the AT command. The response of the modem must be OK displayed in the Hyperterminal window.

If the communication cannot be established with the modem, do the following:

Check the RS232 connection between the DTE and the modem (DCE), Check the configuration of the port COM used on the DTE.

2.43 Verifying the received signal strength

To verify the received signal strength, do the following:

Using a communication software such as HyperTerminal program, enter the AT command AT+CSQ. Value appears for the received signal strength.

Verify the result with the values given in the table below：

2.44 Verifying the network registration of the modem

Make sure a valid SIM card has been previously inserted in the SIM card holder of the modem.

Using a communication software such as HyperTerminal program, enter the

following AT command: AT+CREG? . Value appears as a response. Verify the result with the values given in the table below:

Value Network registration

0,5

Yes (r egistered roaming)

Yes

If the modem is not registered, perform the following procedure:

Check the connection between the modem and the antenna. Verify the signal strength to determine the strength of the received signal (refer to paragraph 2.43)

Chapter 4 Troubleshooting

This section of the document describes possible problems encountered when using the Modem and their solutions.

4.1 No connection with the modem through the serial link

If the modem does not answer through the serial link, refer to the table below for possible causes and solutions.

If the modem

returns…

Nothing

Then ask Action

Is the modem powered correctly?

Does the serial cable follow correctly pin assignment shown in paragraph 1.2.1.3.

Is the communication

program properly configured?

Provide a power supply in the

range of 5 V (5.5V for GPRS Class 10) to 32 V.

Connect the cable by following pin assignment given in paragraph 1.2.1.3.

Ensure the setting of the

communication program is fit to setting of modem.

Modem factory setting is: Data bits = 8 Parity = none

Stop bits = 1

Baud = 115200 bps or 9600bps Flow control = Hardware

Is there another program

interfering with the communication program

(i.e. Conflict on communication port

access)

GSM/GPRS Modem User's Manual

Close the application (e.g. mouse or printer driver).

Chapter 4 Troubleshooting

4.2 Receiving "ERROR" Message

If the modem return a message of ERROR upon an attempted transmission of data, or voice signals, then refer to the table below for possible causes and solutions.

If the modem

returns…

ERROR

Then ask Action

Is the modem registered on the network?

Is the modem receiving an incoming call or is it already

in communication?

Is the selected bearer type is supported by the called

party? Is the selected bearer type is supported by the network?

Refer to paragraph 4.4 to verify that th e modem is

registered on the network.

End any incoming by using ATH command.

Enter AT+CMEE to view the extended error code.

Note: Refer to Table 1 5. Ensure that the selected bearer type is supported by the called party.Ensure that the semicolon (;) is entered immediately after the phone number in the AT command. e.g. ATD######;

Is the received signal strong

enough?

Is the antenna properly connected?

Refer to paragraph 3.4 to verify the

strengt h of th e received signal.

Refer to paragraph 2.3 for antenna requirements

4.3 Receiving "No carrier" Message

If the modem return a message of No carrier upon an attempted transmission of data, or voice signals, then refer to the table below for possible causes and

solutions.

If the modem

returns…

No c arrier

No c arrier (when trying to i ssue a voice communication )

No c arrier (when trying to i ssue a

data communication)

Then ask Action

Is the received s ignal strong enough?

Is the antenna pr operly connected?

Is the semicolon (;) entered immediately after the phone number in the AT command?

Is SIM card configured for data / fax calls?

Is the selected bearer type supported by the called party? Is the selected bearer type supported by the network?

Refer to paragraph 4.3 to verify the strength of t he received signal.

Refer to paragraph

3.4 fo r antenna requirements.

Ensure that the semicolon (;) is entered immediately after the phone number in the AT command. e.g. ATD######;

Configure the SIM card for data / fa x calls (Ask your network provider if

necessary).
