2.2 RS232 serial link
2.2.1 General presentation
The RS232 interface performs the voltage level adaptation (V24/CMOS
⇔
V24/V28) between the internal WISMO module (DCE) and the external world
(DTE).
The RS232 interface is protected (by ESD protection) against electrostatic surges on the RS232 lines.
Filtering guarantees:
EMI/RFI protection in input and output,
Signal smoothing.
A flexible 6-wire serial interface is available complying with RS232 protocol signaling.
The signals available are:
•
TX data (CT103/TX),
•
RX data (CT104/RX),
•
Request To Send (CT105/RTS),
•
Clear To Send (CT106/CTS),
•
Data Terminal Ready (CT108-2/DTR),
•
Data Set Ready (CT107/DSR).
The 2 additional signals are Data Carrier Detect (CT109/DCD) and Ring
Indicator (CT125/RI).

2.3 RESET
2.3.1 General presentation
This signal is used to force a reset procedure by providing low level during at least 500 µs.
This signal has to be considered as an emergency reset only. A reset procedure is automatically driven by an internal hardware during the power-up sequence.
This signal can also be used to provide a reset to an external device. It then behaves as an output. If no external reset is necessary this input can be left open, if used (emergency reset), it has to be driven by an open collector or an open drain output:
•
RESET pin 14 = 0, for Modem Reset,
•
RESET pin 14 = 1, for normal mode.

Additional comments on RESET:
The RESET process is activated either by the external RESET signal or by an internal signal (coming from a RESET generator). This automatic reset is activated at Power-up.
The modem remains in RESET mode as long as the RESET signal is held low.
This signal should be used only for “emergency” resets .
A software reset is always preferred to a hardware reset.
2.3.2 Reset sequence
To activate the « emergency » reset sequence, the RESET signal has to be set to low for 500
µ s minimum.
As soon as the reset is complete, the AT interface answers « OK » to the application. For this, the application has to send
AT
↵
.
If the application manages hardware flow control, the AT command can be sent during the initialisation phase. Another solution is to use the AT+WIND command to get an unsolicited status from the modem.
For further details, refer to AT commands documentation [1].

4.1.3 Checking the communication with the modem
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: 115.200 kbps,
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.
Example of AT commands which can be used after getting started the modem:
- AT+CGMI: modem answer is “WAVECOM MODEM” when serial link is
OK.
-
AT+CPIN=<Pin Code>: to enter a PIN code (if activated).
-
AT+CSQ: to verify the received signal strength.
-
AT+CREG?: to verify the registration of the modem on the network.
-
ATD<phone number>;: to initiate a call.
- ATH: to hang up (end of call).
For further information about these AT commands and their associated
parameters, refer to document [1].
4.1.4 Resetting the modem
For resetting the modem, a hardware reset signal is available on pin 14 of the
Sub HD 15-pin connector (RESET).
The reset of the modem is carried out when this pin is low for at least 500
µ s.
For further details about the reset of the modem, refer to paragraph 2.3.

7 Safety recommendations
WM_PRJ_M12_UGD_001 - 002
18th September 2003
7.1 General Safety
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 refuelling point.
Switch OFF your GSM Modem in hospitals and any other place where medical equipment may be in use.
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.
Operation of your GSM Modem close to other electronic equipment may also cause interference if the equipment is inadequately protected. Observe any warning signs and manufacturers recommendations.
The modem is designed for and intended to be used in fixed and mobile applications:
“ Fixed” means that the device is physically secured at one location and is not able to be easily moved to another location.
“
Mobile” means that the device is designed to be used in other than fixed locations and generally in such a way that a separation 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 and intended to be used in portable applications (within 20 cm of the body of the user) and such uses are strictly prohibited. confidential ©
