8 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 cannot embrace all the hardware solutions and products that may be designed.

9 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 motherboard 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 one is the only possibility with portable personal computers that generally have not the RS232 port. Furthermore, the EVK2 allows benefiting 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 USB1.1 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 presents a proper design of all the interfaces towards and from the module (e.g. power supply, audio paths, level translators), Reproduction forbidden without Telit Communications S.p.A. written authorization - All Right reserved page 9 of 89

10 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. 2.1 Contents of the kit Please check out the contents of your EVK2 kit; if any of the items is missing, please contact your supplier.

19 6.4 Battery Charging with GM862-GPRS Telit EVK2 User Guide If you are using a GM862-GPRS, the Battery Pack must be charged stand-alone, due to the lack of the requested internal circuit. 6.5 Application Notes About Li-Ion Battery Pack The 3.7V Li-Ion rechargeable Battery Pack should be connected directly to PL107 connector. 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) 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 of the Internal Charge Algorithm. Depending on the size, the Li-Ion cell manufacturers suggest a charge current value not greater than 1,5C 1 ; 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: Ich Vbe = Q102 R par where R par = //R110, R111, R112, R113 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. 1 Capacity of the battery pack, expressed in mah Reproduction forbidden without Telit Communications S.p.A. written authorization - All Right reserved page 19 of 89

21 7.1 Serial Port Setup 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 stacked standard RS232 communications port (double 9way D-socket 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). UPPER ATcommands/PROGRAM LOWER SERVICE DB9 Stacked ddb9a.skd CS1139A Figure 10: Double 9way D-Socket Connector 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 single line could be isolated apart. 1 2 SO501 USB PL502 SO501 USB PL502 SO101 CS1139A CS1139A SO SO RS232 STACKED RS232 USB 1 RS232 MODE PL303 PL302 PL301 RS232 STACKED RS232 USB USB MODE PL303 PL302 PL301 usb_rs.skd Figure 11: Serial Ports selection.

23 9 Audio outputs The output audio signals could be drive a device connected to SO401 (LOW AF POWER mode) or to PL401 (HIGH AF POWER mode). 9.1 Low AF Power Mode A standard off-the-shelf Earphones should be connected to the SO401 (3 contacts, 2.5mm diameter plug connector), inserting the 2 contacts jumpers as explained at paragraph 8. With such an insertion, the Telit Modules will directly power the Microphone through an Unbalanced/Unbuffered input circuit and the Earpiece 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. REMINDER: the coil impedance of the Earpiece should be higher than 15Ω@1KHz CS1139A PL RS232 USB RS232 STACKED 1 1 AUDIO 1 AUDIO 2 SPEAKER headphon.skd HEADSET Figure 13: Earphones insertion Reproduction forbidden without Telit Communications S.p.A. written authorization - All Right reserved page 23 of 89

Connecting an 8Ω Speaker to PL401 by a 2 contacts female connector, you could drive it through a 500mW Power Amplifier. In this case the Speaker is driven by a BTL Amplifier (Bridge Tied Load), 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 of this amplifier can be modified varying the ratio R406-R404 bearing in mind that: R404 Av = 1+ 2 R406 REMINDER: the coil impedance of the Speaker should be higher than 8Ω@1KHz CS1139A PL RS232 STACKED RS232 USB 1 1 AUDIO 1 AUDIO 2 SEPARATE SPEAKER speaker.skd Figure 15: Speaker insertion Reproduction forbidden without Telit Communications S.p.A. written authorization - All Right reserved page 24 of 89

31 11.2 Switches By 2 push button you turn on or reset the EVK POWER ON Switch 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) RESET Switch Whenever the RESET SWITCH is pressed, you could reset the Telit module in use. When the device is reset, it stops any operation without doing any detach operation from the network where it is registered and it reboots after the release of the Reset Switch. Only for GM862GSM and GM862GPRS it shuts down after the release of the Reset Switch. 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 reboot/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 RS232 USB AUDIO 1 AUDIO STATUS LED CS1139A switch_a.skd RESET ON Figure 21: SWITCHES position Reproduction forbidden without Telit Communications S.p.A. written authorization - All Right reserved page 31 of 89
