GSM Module M1
The GSM module is a GSM terminal for transmitting data, faxes and SMS (short mes-
sage service) text messages in GSM networks (GSM = global system for mobile com-
munication).
The GSM Module M1 comprises the following components:
• GSM transceiver;
• Data and power supply unit;
• Serial interface (V.24) for data transmission and control;
• Manufacturer-specific interface for DC power supply, external antenna and audio
signals.
When the GSM Module M1 is registered in the network, it serves as a standard mo-
dem for fax and data transmission for a computer connected to the V.24 interface. Spe-
cial AT+C commands as per GSM 07.07 or GSM 07.05 for controlling GSM-related
functions (PIN entry, network selection, etc.) and for the short message service are
available via the V.24 interface.
The GSM Module M1 offers the following features:
• Transparent data transmission at 2400, 4800 and 9600 bps (BS24,25,26);
• Group 3, Class 2 fax transmission conforming to TR-29.2 at 2400, 4800, 7200
and 9600 bps;
• Short message service mobile originated (SMS MO, TS22)
• Short message service mobile terminated (SMS MT, TS21)
The GSM Module M1 conforms to GSM standards. However, note that the device can
still emit radiation and therefore must not be used or even switched on in certain envi-
ronments.
• Leaving the GSM Module M1 switched on in airplanes is prohibited by law.
• The module must not be used near service stations, fuel depots, chemical plants or
blasting operations.
• The module may also interfere with the functioning of electronic medical devices
(hearing aids, pacemakers, etc.) that are not properly shielded. In case of doubt, con-
sult your physician. Do not touch the antenna during a call.
• Using the GSM Module M1 in the direct vicinity of electronic devices (radios, tele-
visions, PCs, etc.) can cause slight interference.
