Description
The GSM-Q2403 Modem is ideal for a wide range of applications. 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 .

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
Power SupplyPower Supply
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
RS232 InterfaceRS232 Interface
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).
The GSM/GPRS Terminal is designed for use as DCE. Based on the conventions for DCE-DTE connection,
it communicates with the user application (DTE) using the following signals:
Pin TxD @ application sends data to TxD of GSM/GPRS Terminal
Pin RxD @ application receives data from RxD of GSM/GPRS Terminal
