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.

INSTALLATION/START-UP
2.3 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 : 5 to 32V DC (GSM 900) - 6 to 32V DC (GSM 1800/1900) GND : 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?
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?
A suitable cable must follow pin assignment described on figure 6.Check in particular , that Rx et Tx are properly connected.
C) Check that your communication program is properly configured:
Modem factory setting for the character framing are:
Data Bits : 8 Parity : None Stop Bits : 1
The factory setting for baud rate is autobauding mode.
D) Does any other program interfere with your communication program (conflict on communication port access)?
TROUBLESHOOTING
Wavecom WMO2 Modem 12
If yes, close any application likely to interfere (e.g. mouse or printer driver).
GUIDE 19/04/99, 9:2215
5.2 The modem always returns «Error» when trying to issue a communication
