The modem can be used to make circuit switched data calls (CSD), making the unit suitable for remote dial-up systems where a fixed phone line is not available. The SMS functionality enables the sending and receipt of text messages. A common use for this functionality is an SMS server for the automated sending and receipt of bulk text messages. The modem implements the Wavecom 2403 GSM Engine. This ensures high quality and reliable operation along with compatibility with all standard GSM networks. The modem is supplied in a rugged extruded aluminium enclosure making it suitable for use in a wide range of industrial and demanding environments. The unit connects directly to a PC or terminal device via the DB-9 RS232 Cable interface. The integral SIM card holder accepts standard SIM cards . The only other connections required are to dc power supply and Antenna .

Page 2 GSM /GPRS Modem GSMGSM-Q2403 Interface description The GSM Terminal provides the following connectors for power supply, interfacing and antenna: • 2.1mm DC power connector (centre/inner pin is positive) • 9-pin (female) D-SUB plug for RS-232 serial interface • SMA connector for antenna (radio interface) • SIM card holder Power Supply The power supply of the GSM Terminal should be a single voltage source of Vin=6-36V providing a peak current of up to 500mA during transmission. The terminal can be turned on by connecting power. The terminal power supply circuit automatically generates a low pulse signal not less than 100ms in order to wake up the GSM engine. Each time the terminal is shut down, data will be written from the volatile memory to flash memory. The guaranteed maximum number of write cycles is limited to 100,000. RS232 Interface Via RS-232 interface, the host controller controls the TMAS GSM/GPRS Terminal and transports data. The table below shows the pin assignment of RS-232 (D-SUB 9-pin female).
