1 Overview
Aim of this document is the handling description of the developer’s Evaluation KIT second edition, a laboratory tool named EVK2 in the rest of this document. All given information shall be used as a guide and a starting point for properly developing of your product. Obviously this document can not embrace all the hardware solutions and products that may be designed.
2 Generality
Telit supplies the EVK2 to assist the designer during his developing project phase to develop his own applications based on actual and next GSM/GPRS/PCS Telit modules. The EVK2 provides a fully functional solution for a complete data/phone application. The EVK2 is formed by a mother board CS1139a and several dedicated Telit modules Interface Boards with RF antenna connectors. 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 two-way communication in compliance with USB version 1.1 specification up to 1,5Mbytes/sec. The second 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 and GPS satellite positioning receiver . The ASC1, accessible as RS232 on lower DB9 connector or through the USB1.1HUB , is used for :
- continuous of debug messages of the PYTHON Script Interpreter (requires PYTHON version modules ;
- continuous direct output of GPS NMEA sentences (geographical coordinates) from modules with GPS .
The development of the applications utilizing Telit modules present a proper design of all the interfaces towards and from the module (e.g. power supply, audio paths, level translators), otherwise a decrease in performance will be introduced or, in the worst case, a wrong design can even lead to an operating failure of the module.

It is also easily feasible the use of the Telit modules in the so called “ stand-alone configuration “, connecting the module mounted on its own interface board directly to your application, through 2x40 pin header connectors . For further detailed description refer to Technical Specification 30276st10285a_r4 .

Remember to use the connection cables as short as possible, with the appropriate conductor gauge and the other attributes, such as device power budget and cable flexibility, in order to match the specified voltage drop (especially during the high current absorption periods). To obtain the best performance we suggest a capacity of 1000 mAh (not lower than 500 mAh ).
4.5 About Current Charger With a +6V Current Unlimited Source connected to PL103 connector, the battery pack will be directly
charged through VBATT connector pins of the Telit Modules, under control by the Internal Charge Algorithm.
Depending on the size, the Li-Ion cell manufacturers suggest a charge current value not greater than 1,5C (*) ; even if a lower current means a longer charging time, a current equal to 0,5C is considered to be a good choice. With reference to the schematic diagram 30276SE11139A -sheet1, the Current Limiting Circuit (Q102, Q103, R106, R107, R108, R109, R110, R111, R112, R113, C105) sets the maximum value of the Charge Current in respect to the law:
RVbeI
par
Qch
101= where 113,112,111,110// RRRRR par =
With the default values, the charge current will be ∼ 470mA, which will charge Battery Packs with a capacity from 350mAh to 1000mAh, without any dissipation problem. If a higher capacity Battery Pack is needed, you must increment the Time Out in the Telit Modules. * = capacity of the battery pack, expressed in mAh
5 Serial interface setting
Communications between your application and the Telit modules are allowed connecting the DTE to the Asynchronous Serial Interfaces of Base-Band Chip, ASC0 and ASC1, through the double stacked standard DB9 connector (at slow data rates of RS232 protocol) or a standard USB-B Series receptacle (at higher data rates of USB1.1 specification through a CMOS HUB that realizes a multiple attachment point device). To make the selection you must short PL302&PL303 (RS232 mode) or PL302&PL301 (USB 1.1 mode) by 10 pieces of 2 contacts jumpers. This solution has been implemented because every line could be isolated independently from the others.

With such an insertion, the Telit Modules will directly power the Microphone through an Unbalanced/Unbuffered input circuit and the Earpiece (called also mini speaker) through a Single Ended/ AC coupled circuit. Note that the acoustic Earpiece performance (frequency response, loudness) largely depends by its housing, fitting and acoustic impedance.

7.2 High AF Power Mode Connecting a Speaker to PL401, you will drive it through a 675mW Power Amplifier. In this case the Speaker is driven by a BTL (Bridge Tied Load) Amplifier, with no side connected to ground and without any output coupling capacitor. Therefore care must be taken because on both sides of the Speaker there is a DC voltage. The overall gain can be modified varying the ratio R406-R404 bearing in mind that:
REMINDER: the coil impedance of the Earpiece should be higher than 15Ω@1KHz

9.2 Switches By 2 switches you turn on and reset the EVK2.
9.2.1 Power ON Button
Pressing for at least 2 seconds the Power ON SWITCH, you turn On/Off the whole EVK2 and the Telit module in use: the STAT_LED starts to slowly blink (ON state) or stops to blink (OFF state).
9.2.2 RESET Switch
Whenever the RESET button is pressed you could reset the Telit module in use. When the device is reset, it stops any operation and after the release of the reset it shuts down, without doing any detach operation from the network where it is registered to. This behavior is not a proper shut

down because any GSM device is requested to issue a detach request at turning off. For this reason the Reset pressing action must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stuck waiting for some network response. The RESET is internally controlled at start-up to achieve always a proper power-on reset sequence, so there is no need to control this pin on start-up. It may only be used to reset a device already on that is not responding to any command.

11 Module Interface & Extension Boards
11.1 Short description You can use the EVK2 with every Telit module fitted on its own Interface Board; all connections are made through 2x40 contacts connectors. It is possible to use the Interface Boards also in stand-alone mode, previous insertion of the “not mounted” components (related to RESET BUTTON, ON BUTTON, SIM HOLDER and STATUS LED functions ) using an external level translator circuit. A Dual Camera Extension Board is available : it must be plugged on top of the Interface Board in use. It can support two different types of VGA Camera by ZIF connector insertion . Note that: 1) CS1098 (TRIZIUM® Camera EVB,3990400474) is not compatible with EVK2: you have to use the new Dual Camera Extension Board (CS1170) board to connect a Camera previously used with a CS1098 ; 2) With reference to GM862, actually we can use only the AGILENT Camera type.
11.2 Cross list In the following table you can find the cross list of the Interface and Extension boards that form the EVK2 system; new boards will be designed for the future ones.

12 GPIO ports
A certain number of GPIO ports (General Purpose Input/Output) are at your disposal on Every Telit Module Interface Board, giving you the possibility of drive digital devices and report their own status. Some of these ports are dedicated and provide a direct support for a digital CMOS CAMERA; obviously when you are using the CAMERA, the number of available GPIO is reduced. Refer to Telit Product Specification to have all information about characteristics of every GPIO port.
