8.7 The Evaluation Kit for Telit Modules EVK2
8.7.1 Short Description
Telit supplies the Evaluation Kit for Telit modules EVK2 to assist the designer to develop his own applications based on
The EVK2 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 data/phone application.
The motherboard has multiple power supply possibilities and is equipped with SIM card housing, RS 232 serial port level translator, direct USB1.1 connection, and two audio input/output paths.
The only items you have to provide are:
1)a personal computer or microcontroller ;
2)a SIM card with a valid Network subscription;
3)the audio accessories;
4)a knowledge of AT commands programming ;
5)a power supply
The connection between the EVK2 and your PC (or other DTE) are realized by standard RS232 or USB 1.1 ports.
The communications between your application and Telit Modules are realized connecting the Asynchronous Serial Interfaces of the module’s Base Band Chips (ASC0 and ASC1) through:
a double stacked standard DB9 connector, that provides 2 serial communication paths RS232 protocol up to 115Kbit/sec .
a CMOS HUB, that makes both serial interfaces accessible through one physical connection providing
The second one is the only possibility with portable personal computers, that generally have not the RS232 port .
Furthermore, the EVK2 allows to benefit of the special features of the new Telit Module versions with PYTHON Script Interpreter
