Mounting the modem For mounting the modem, bind to the body the holding bridles according to the schema below :
Note: - To be attached to a plain surface - Screw head max. height: 2mm

Holding bridles

Figure 2 Modem mounting 2.2 Installing the modem
To install the modem, plug the device on a DC power supply (for automotive application, connect the device on the permanent + and insert the SIM card in the holder).
Make sure that an antenna is connected. In order to extract or to insert the Micro SIM card, it is necessary to press the SIM holder ejector with a sharp element (a pen for example). If this sequence is not respected, the SIM holder could be damaged.

Electrical characteristics
2.3.1 Switching the GSM modem on/off The device is permanently powered (when connected to the power supply). 2.3.2 Voltage range Voltage range GND : : 5 to 32V DC (GSM 900) - 6 to 32V DC (GSM 1800/1900) 0V
2.3.3 Overvoltage/undervoltage
Correct operation of the Wavecom WMO2 modem in communication mode is not guaranteed if input voltage fall below 5V (GSM 900) - 6V (GSM 1800/1900). The modem is protected against voltage over 32V. When input voltages exceed 32V, the supply voltage is disconnected in order to protect the electronic components from an overvoltage. TWO CASES ARE POSSIBLE: - IF THE OVERVOLTAGE IS CONTINUOUS, THE PROTECTION IS GUARANTEED BY THE FUSE. - IN THE CASE OF TRANSIENT PEAKS, THE MODEM GUARANTEES ITS OWN PROTECTION.

5. TROUBLESHOOTING: Specific defaults possibly encountered
5.1 The modem does not answer through the serial link A) Is the modem correctly powered on? t If not, the correct power supply is 5 to 32V (GSM 900) - 6 to 32V (GSM 1800/1900). B) Is the serial cable suitable and adjusted in the modem and PC sockets? t A suitable cable must follow pin assignment described on figure 6. t Check in particular, that Rx et Tx are properly connected. C) Check that your communication program is properly configured: t Modem factory setting for the character framing are: Data Bits : 8 Parity : None Stop Bits : 1 t The factory setting for baud rate is autobauding mode.

TROUBLESHOOTING

D) Does any other program interfere with your communication program (conflict on communication port access)? t If yes, close any application likely to interfere (e.g. mouse or printer driver).
The modem always returns Error when trying to issue a communication A) Issue AT+CMEE=1 to have extended error cause and retry
Cause value Diagnostic Phone failure Operation not allowed Operation not supported SIM not inserted SIM PIN required SIM PUK required SIM Failure Incorrect password SIM PIN2 required SIM PUK2 required Dial string too long No network service Insert the SIM card in the SIM holder of the modem, If SIM card is inserted, insure that it is properly inserted. Enter PIN code Enter PUK code (call your network provider if you don t know this code) Check validity of your SIM card. If SIM damaged, call your network provider Check the code you entered Enter PIN2 code Enter PUK2 code (call your network provider if you don t know this code) Check your phone number (max 20 digits) Call your technical support Hint
For all other codes, and/or details, see AT commands manual. B) Additional hints t Is the modem registered on the network? Does the AT-Command AT + CREG? answers 0,1 (registered) or 0,5 (registered roaming)?
If not, check that the received signal is strong enough to synchronize on the Network (use AT+CSQ).
Is the modem receiving an incoming call or already in communication? With some software versions, you must release any incoming or active call (with ATH) before being able to make an outgoing call.
The modem always returns No carrier when trying to issue a communication A) After a failed attempt (no carrier), issue AT+CEER to have extended error cause
Cause value Diagnostic Unallocated phone number Normal call clearing User busy No user responding User alerting, no answer Call rejected Number changed Normal, unspecified Requested facility not subscribed ACM equal or greater than ACMmax Call baring on outgoing calls Call baring on incoming calls Network causes See AT commands manual for further details or call network provider Check your subscription (data subscription available?) Credit of your pre-paid SIM card expired Hint
3, 6, 8, 29, 34, 38, 41, 42, 43, 44, 47, 49, 57, 58, 63, 65, 69, 70, 79, 254
For all other codes, and/or details, see AT commands manual. Wavecom WMO2 Modem 14
B) Additional hints t Is the antenna properly connected? For GSM 900 : use a 870 to 960 MHz / 50 Ohms antenna. For GSM 1800 : use a 1710 to 1880 MHz / 50 Ohms antenna. For GSM 1900 : use a 1850 to 1990 MHz / 50 Ohms antenna. t Is the received signal strong enough? With the AT-Command AT+CSQ check that the received signal (1st parameter of the response) is strong enough to be able to establish a call.

AT+CSQ response (RSSI) 11 to to 10 and +99
Signal quality Should be sufficient* Could be insufficient*
* based on general observations.
The modem always returns No carrier when trying to issue a voice communication? Insure the character semicolon is present straight after the phone number on the AT-Command ATD######; The modem always returns No carrier when trying to issue a data communication? Insure the selected bearer type is supported by the called party. Then, insure the selected bearer type is supported by the Network. If no success, try bearer selection type: AT+CBST=0,0,3. Insure the SIM Card is available for Data/Fax calls.
