Using GSM Module - Telit GL865T-Dual Terminal

Sooner or later collected data must be stored. These modules accomplish this task by using GSM/GPRS networks.

The terminal can operate between -40 °C and +85 °C

Some information about the terminal:

1. Dimensions: 85 x 70 x 33 mm. Weight: 140g.
2. Acceptable power voltages are between 9 and 32V. It needs minimum 1.2 Ampere.
3. Serial communication is made with a RS232 port. A USB-RS232 cable is handy when establishing a terminal connection between the terminal and a pc. RS232 is the D type serial port in the old motherboards.
   
4. A low cost GSM antenna can be installed to increase signal reception.
5. There is a SIM card slot that accepts large type card.
6. There is a python interpreter (version 1.5.2) in the terminal, letting a custom python script run continuously.

After connecting the RS232 port with a USB port in the pc, there are a number of ways to communicate with the terminal.

If the java installation of the pc is current, then this online applet is the easiest connection method:
