9The Evaluation Kit for Telit GE863- PRO3 Modules

9.1.1 Short Description

Telit supplies the Evaluation Kit for Telit GE863-PRO3modules to assist the designer in developing his own applications based on GE863-PRO3Telit module.

The GE863-PRO3EVK is formed by a mother board and a dedicated Telit module Interface Board with RF antenna connectors.

It provides a fully functional solution for a complete M2M application.

The motherboard has a power supply and is equipped with SIM card housing, RS 232 serial port level translator, direct USB2.0 Host & Device connection, Smartcard ISO7816 slot, SD-MMC Card slot and 10/100 Mb Ethernet.

The only items you have to provide are:

1)a personal computer or microcontroller ;

2)a SIM card with a valid Network subscription;

3)a power supply

The connection between the GE863-PRO3EVK and your PC (or other DTE) are realized by standard RS232 ports.

The communications between the application ARM and Telit GSM/GPRS engine is realized connecting the Asynchronous Serial Interfaces of the module’s ARM&GSM/GPRS by setting appropriately the Jumpers.

Furthermore the communications between ARM and GSM/GPRS can be analyzed with two “sniffed” serial ports that can report both sides of the ARM-GSM/GPRS serial channel.
