7 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 CS39a 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 USB. connection, and two audio input/output paths. The only items you have to provide are: ) 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 or USB. 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 ASC) through: a double stacked standard DB9 connector, that provides 2 serial communication paths protocol up to 5Kbit/sec. a CMOS HUB, that makes both serial interfaces accessible through one physical connection providing two-way communication in compliance with USB version. specification up to,5mbytes/sec. The second is the only possibility with portable personal computers, that generally have not the 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 ASC, accessible as on lower DB9 connector or through the USB.HUB, 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

Reproduction forbidden without Telit Communications S.p.A. written authorization All Right reserved Right of modification reserved page 5 of 37

16 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 000 mah (not lower than 500 mah ). 4.5 About Current Charger With a +6V Current Unlimited Source connected to PL03 connector, the battery pack will be directly charged through 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,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 30276SE39A -sheet, the Current Limiting Circuit (Q02, Q03, R06, R07, R08, R09, R0, R, R2, R3, C05) sets the maximum value of the Charge Current in respect to the law: I ch = Vbe R Q 0 par where // R 0, R, R 2, R 3 R par = With the default values, the charge current will be 470mA, which will charge Battery Packs with a capacity from 350mAh to 000mAh, 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 ASC, through the double stacked standard DB9 connector (at slow data rates of protocol) or a standard USB-B Series receptacle (at higher data rates of USB. specification through a CMOS HUB that realizes a multiple attachment point device). To make the selection you must short PL302&PL303 ( mode) or PL302&PL30 (USB. mode) by 0 pieces of 2 contacts jumpers. This solution has been implemented because every line could be isolated independently from the others.

19 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.

29 Module Interface & Extension Boards Telit EVK2 User Guide. 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: ) CS098 (TRIZIUM Camera EVB, ) is not compatible with EVK2: you have to use the new Dual Camera Extension Board (CS70) board to connect a Camera previously used with a CS098 ; 2) With reference to GM862, actually we can use only the AGILENT Camera type..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.

35 4 SAFETY RECOMMENDATIONS READ CAREFULLY Be sure the use of this product is allowed in the country and in the environment required. The use of this product may be dangerous and has to be avoided in the following areas: Where it can interfere with other electronic devices in environments such as hospitals, airports, aircrafts, etc Where there is risk of explosion such as gasoline stations, oil refineries, etc It is responsibility of the user to enforce the country regulation and the specific environment regulation. Do not disassemble the product; any mark of tampering will compromise the warranty validity. We recommend following the instructions of the hardware user guides for a correct wiring of the product. The product has to be supplied with a stabilized voltage source and the wiring has to be conforming to the security and fire prevention regulations. The product has to be handled with care, avoiding any contact with the pins because electrostatic discharges may damage the product itself. Same cautions have to be taken for the SIM, checking carefully the instruction for its use. Do not insert or remove the SIM when the product is in power saving mode. The system integrator is responsible of the functioning of the final product; therefore, care has to be taken to the external components of the module, as well as of any project or installation issue, because the risk of disturbing the GSM network or external devices or having impact on the security. Should there be any doubt, please refer to the technical documentation and the regulations in force. Every module has to be equipped with a proper antenna with specific characteristics. The antenna has to be installed with care in order to avoid any interference with other electronic devices and has to guarantee a minimum distance from the people (20 cm). In case of this requirement cannot be satisfied, the system integrator has to assess the final product against the SAR regulation. The European Community provides some Directives for the electronic equipments introduced on the market. All the relevant information s are available on the European Community website: The text of the Directive 99/05 regarding telecommunication equipments is available, while the applicable Directives (Low Voltage and EMC) are available at: Reproduction forbidden without Telit Communications S.p.A. written authorization All Right reserved Right of modification reserved page 35 of 37
