Installing the modem
To install the modem, plug the device on a DC power supply (for automotive applications, 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.

2.3.3 Overvoltage/undervoltage
Correct operation of the Wavecom WMOD2B modem in communication mode is not guaranteed if input voltage
fall below 5V. 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.
TROUBLESHOOTING
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 the baud rate is 9600 bps.
D) Does any other program interfere with your communication program (conflict on communication port access)?
❑ If yes, close any application likely to interfere (e.g. mouse or printer driver).

distance of at least 20 cm (8 inches) is normally maintained between the transmitter’s antenna and the body of the
user or nearby persons. The Modem is not designed for a intended to be used in portable applications (within 20
cm of the body of the user) and such uses are strictly prohibited.
It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully.
❑ Switch OFF your GSM Modem when in an aircraft. The use of cellular telephones in an aircraft may endanger the operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this instruction
may lead to suspension or denial of cellular telephone services to the offender, or legal action or both.
❑ Switch OFF your GSM Modem when at a refueling point.
❑ Switch OFF your GSM Modem in hospitals and any other place where medical equipment may be in use.
Wavecom WMOD2B Modem
16
❑ Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting operations are in progress.
❑ There may be a hazard associated with the operation of your GSM Modem close to in adequately protected
personal medical devices such as hearing aids and pacemakers. Consult the manufactures of the medical
device to determine if it is adequately protected.
7.2
Vehicle Safety
❑ Do not use your GSM Modem while driving, unless equipped with a correctly installed vehicle kit allowing
‘Hands-Free’ Operation.
❑ Respect national regulations on the use of cellular telephones in vehicles. Road safety always comes first.
❑ If incorrectly installed in a vehicle, the operation of GSM Modem telephone could interfere with the correct
functioning of vehicle electronics. To avoid such problems, ensure that the installation has been performed
by a qualified personnel. Verification of the protection of vehicle electronics should form part of the installation.
❑ The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.
7.3
Car And Maintenance
Your GSM Modem is the product of advanced engineering, design and craftsmanship and should be treated with care.
