2. INTRODUCTIONThe Nokia 12 module has been designed for M2M (machine-to-machine)applications and other wireless solutions. There are two versions of the Nokia12 module:• RX-2 dual-band GSM device supporting EDGE, GPRS, HSCSD, CSD, andSMS in EGSM 900/GSM 1800 MHz bands• RX-9 dual band GSM device supporting EDGE, GPRS, CSD, SMS in GSM850/GSM 1900 MHZ bands.The Nokia 12 module can be used in several applications due to its threedifferent operating modes. Simple I/O applications can be easily implementedby using the Nokia 12 module in the User control mode that offers messagepersonalising, secure messaging, and timing functionality for SMS controlledI/O applications. In the AT command mode, the Nokia 12 module can be usedas a GSM modem. In modem use, all supported bearers are available. TheNokia 12 module is Nokia M2M Platform compatible. In the M2M system mode,the Nokia 12 module communicates with the server application through theNokia M2M Gateway, and all the compatible features of the Nokia 12 moduleare available for developing a wide range of M2M applications.In addition to the different operating modes, the Nokia 12 module has anintegrated TCP/IP stack which enables direct GPRS or GSM data connectionbetween a remote end application and a server application. Due to theintegrated TCP/IP stack, the HTTP and Socket APIs of the Nokia 12 areavailable for application development.In addition to the bearers and operating modes listed above, the Nokia 12supports several Java APIs, location service for external GPS moduleintegration, reliability features like AutoPIN, GSM encryption and securitycodes, reset mechanism and Nokia M2M Platform authentication. Javatechnology support enables upgrading the application software over-the-air,and smart messaging makes the installation flexible. GSM phase 2+supplementary services enable voice application development.Note: All data bearers as well as TCP/IP are dependent on network support.4/44

4.2 GROUNDINGThere is only one common ground for the power supply and I/Os in the Nokia12 module. That is, there are no separate analog/digital ground pins in the M2MSystem Connector.All ground pins must be connected together at the application end. Groundingthrough screws is not allowed. The mounting screws must be isolated from theapplication ground.4.3 POWER SUPPLYThe Nokia 12 module is powered by the hardware application to which it isintegrated. The operating voltage must not fall below the specification limitunder any circumstances. The recommended operation conditions are shown inTable 4. For example, at full power, the TX can be up to 2 A, when current isdrawn from the power supply. There are no capacitors on the power supply lineof the Nokia 12 module, so the application must provide sufficient filtering.The power supply must be capable of supplying at least 3 W average power,but it is recommended that the power supply also provides the peak current.Otherwise a large capacitor bank is needed to compensate the voltage dropduring transmit bursts.The Nokia 12 module does not have protection for over-voltage of current, sothe hardware application must be equipped with one if there is a possibility forover-voltage. The hardware application should at least include a fuse.The ripple on the operating voltage must not exceed 100 mV and the voltagemust never drop below 3.6 V during operation.The application must also produce I/O voltage. The logic levels of digital inputsand outputs correspond to this I/O voltage. I/O voltage can be supplied from alinear regulator.16/44

Figure 3. Example powering with simple DC/DC converter and linearregulator4.4 SERIAL COMMUNICATIONThe Nokia 12 module is accessible through three different asynchronous serialinterfaces with different protocols. The pins provide one asynchronous channelwith a simple handshaking capability. The usage of the 3 ports can beconfigured with the Nokia 12 Configurator software. The Nokia 12 Configuratoris downloadable at www.forum.nokia.com/m2m free of charge.The Nokia 12 module supports the industry standard DB9 RS-232C connection,but an external level converter is required. For more information on theavailable handshake signals for different ports, see Chapters 4.4.1, 4.4.2 and4.4.3.The Nokia 12 module is a DCE (Data Communication Equipment) and thehardware application to which it is integrated is a DTE (Data TerminalEquipment). One possible method of implementing the level conversions is touse a MAX3237 transceiver or an equivalent integrated circuit (IC) levelconverter.Note: When port settings are changed, the new settings will not become validuntil the Nokia 12 module is restarted.4.4.1 PORT1PORT1 provides the first asynchronous channel. This port can be used with full8 signal RS-232 handshaking signals. The baud rate for PORT1 can bebetween 1200 and 230400 bit/s.17/44

Note: Baud rate 230400 bit/s can be used only with AT command mode andautobauding.There are several settings for PORT1. The default setting for PORT1 is ‘HWDetection’. This means that when a 68 kohm resistor is set between the BSI(pin 37) and the ground, the Nokia 12 module enters the AT command modewhen it is started. It is also possible to set the AT command mode on by usingthe Nokia 12 Configurator (the connection type is set to ‘AT’).The Nokia 12 module provides all signals for the industry standard DB9 RS-232C connection, but an external level converter is required.4.4.2 PORT2PORT2 provides the second asynchronous channel with a simple handshakingcapability (only RTS and CTS). The baud rate for PORT2 can be set to 9600,19200, 38400, 57600 or 115200 bit/s. PORT2 is the default port for using theM2M System Protocol. However, if PORT1 is configured to use the M2MSystem Protocol, PORT2 cannot be used.4.4.3 PORT3PORT3 provides the third asynchronous channel with no hardwarehandshakes. The baud rate for PORT3 can be set between 1200 and 115200bit/s.4.5 SIM INTERFACEAll leads from the M2M System Connector to the SIM card reader must beshorter than 15 cm/5.9 inches, because the voltage drop and increasingcapacitance will affect timing. Furthermore, it is recommended that a 100 nFbypass capacitor is placed as close as possible to the SIM reader on the VSIM(pin47) line.The leads between the M2M System Connector and the SIM card reader mustbe protected against interferences, and that is why the striplines must alwaysbe placed within the interlayers of the printed circuit board (PCB).Note: The striplines must never be placed to the overlayer of the PCB.A possible SIM card reader supplier is listed in Table 13.Table 13. Possible SIM card reader supplier18/44

The analog TX path (from the external application to the Nokia 12 module) hasa DC isolation inside the Nokia 12 module with 100 nF capacitors, and thesecapacitors together with the microphone preamplifier input impedance form a 1 storder high pass filter with 32 Hz roll-off (-3 dB).Table 14.

The following chapter gives an example of using the audio properties of theNokia 12 module for voice communication purposes. The circuits presented inthe example illustrate the connection methods.There are also other possibilities for using the Nokia 12 audio interface. Thepresented component values are examples only; the customer can adjust theapplication-specific values to achieve the best performance for the applicationin question.4.6.1.1 Analog audio exampleAnalog TX path: Due to the small audio signal level of the electret microphone,it is recommended to use a preamplifier for the microphone before connecting itto the Nokia 12 module. It is strongly recommended to protect the differentialconnection against RF noise. A microphone preamplifier with 20 dB input gainis recommended for reasonable uplink audio levels.Microphone input: See Figure 5.VANAR5R4VANAC1VANAR3-C2MicPR1+R6R7VANAR2-+C3MicNFigure 5. Single-ended microphone pre-amplifierAnalog RX path: In voice applications, the Nokia 12 module is able to drive anearphone application without external electronics. However, it is also possibleto build a high-volume loudspeaker application by using an external poweramplifier with a high sensitivity loudspeaker. The following paragraphs showexample circuits for both cases.21/44

Earphone application: An earphone can be connected to the Nokia 12 modulewithout external components. In Figure 6 external components are used forEMC purposes to optimise audio quality and reliability.R1L1R2C1C2J1J2Figure 6. Earphone application circuitThe recommended earphone type is dynamic. The maximum allowed load forthis application is 32 ohm. In the example circuit, L1 is the common modechoke for the suppression of common mode disturbance in the earphone lines.J1 and J2 are surge protector gaps for ESD protection. These can be replacedwith varistor or any other state-of-the-art ESD protection component. C1 andC2 are used for RF noise filtering.R1 and R2 are used as an attenuator if the signal level from the Nokia 12module is too high for the application. These resistors can be replaced withlinear potentiometers and thus get adjustable volume control for the earphoneapplication. The following component list gives example values for the circuit:• L1= 1000ohm@100MHz• C1=C2=27pF• R1=R2= Must be defined together with the sensitivity of the earphoneExternal Audio Power amplifier: External audio power must be used if thereis a need to drive low impedance load as loudspeaker. Figure 7 shows anexample connection circuit for differential audio boomer. In this application onlythe connection interface to the Nokia 12 module is presented. For more detailedinformation on the boomer connections and specification, see the boomermanufacturer application note.22/44

Differential external power amplifier connectionRefer to the audio boomer manufacturer and loudspeaker application notes forinformation on maximum safe ratings for the selected components. Also keep inmind the limitation of V DD to avoid overdriving the audio boomer and thusdistorting the output signal unnecessarily.4.6.1.2 Acoustic echoBecause in a GSM voice call the uplink and downlink audios are activated atthe same time, it is recommended to use common sense when evaluating asuitable distance between the loudspeaker and the microphone. The acousticecho canceller inside the Nokia 12 module is tuned so that the optimum resultis achieved with 20 cm or longer distance between the microphone and thespeaker. It is also advisable to locate the microphone and the loudspeaker sothat they are pointed away from each other to achieve the best possible doubletalkperformance.4.6.2 Digital audioThere is a pulse code modulation (PCM) codec interface in the Nokia 12module for digital audio support. The digital audio interface supports signextended13-bit linear code (total 16 bits are transmitted).23/44

4.6.2.1 Sign-extended linear codePCM digital audio data transmission between the Nokia 12 module and theapplication is handled with four signals: PCMDCLK, PCMSCLK, PCMTX, andPCMRX. The format of the data transmission is sign-extended 13-bit linearcode. A total of 16 bits are transmitted, and higher order bits must be signextended.Transmission of data commences after frame sync (PCMSCLK) riseshigh for one PCMDCLK clock cycle. After returning low, each data bit istransmitted on the falling edge of PCMDCLK.PCMDClkPCMSClkPCMTxDataPCMRxData15 14 13 12 11 10MSBSign extended15 14 13 12 11 10MSBSign extended0LSB0LSBFigure 8. Timing of clock and transmission signalsThe application must provide both the PCMDCLK and PCMSCLK. PCMDCLKfrequency is 512 kHz and PCMSCLK is repeated at 8 kHz, that is, at every 64thclock cycle. All bits but the 16 data bits following the frame sync are discarded.PCMDCLK has a typical 50 % duty-cycle; a variation of 5 % can be tolerated.For detailed timing, refer to Figure 9 and Table 16. Tcyc is the cycle time (1.953microseconds) of the 512 kHz clock. The PCMSCLK rising edge must occur atthe maximum of 8 ns after the PCMSCLK rising edge.The pulse width of the frame sync pulse should be one data clock cycle.PCMDClkTd(SCL)PCMSClkTd(PCMTxData)PCMTxDataPCMRxDataTh(PCMRxData)Tsu(PCMRxData)MSBMSBFigure 9.

5. RF AND ANTENNA INTEGRATIONThe RF requirements for the Nokia 12 module are type-dependent:• RF requirements for the RX-2 type follow the ETSI EGSM900/GSM1800phase2+ specifications.• RF requirements for the RX-9 type follow the ETSI GSM850/GSM1900phase2+ specifications.Table 17. RF specifications for the Nokia 12 GSM moduleParameter Value DescriptionRF impedance 50 ohmRF power 2W (class 4) EGSM900 & GSM 8501W (class 1) GSM1800 & GSM 1900The RF signal from the Nokia 12 module to an external antenna goes troughthe MMCX connector.An adapter cable between the MMCX connector and the antenna may beneeded. Suitable connectors and cables are available, for example, fromAmphenol, TYCO, and IMS Connector Systems.The Nokia 12 module is certified with a Smarteq dual-band antenna (art no:1140.26 for 900/1800MHz and 1140.27 for 850/1900MHz). Suitable antennasare available, for example, from Smarteq and Hirschmann.For more information on the RF exposure, see Chapter 7.2.5.5.1 ANTENNA INSTALLATIONThe antenna must be placed within a good RF field; a location where the signalstrength is adequate. A hand-portable phone can be used to check the bestlocation for the antenna.Note: Electronic devices can cause interference, which affects the performance ofthe Nokia 12 module. Do not place the antenna close to electronic devices orother antennas.If an additional cable is needed between the antenna and the Nokia 12 module,use low-loss cables (for example RG-58. Amphenol, Suhner, etc.) andconnectors. Every additional cable, adapter, and connector increases the lossof signal power.26/44

When designing the hardware application to which the Nokia 12 module isintegrated into, it is important to take care of RF emissions. Do not place anysensitive components or striplines near the antenna or the antenna connector.For more information on the RF exposure, see Chapter 7.2.5.27/44

6. TEST BOARD FOR THE NOKIA 12 GSM MODULEThe Nokia 12 test board is a hardware development tool for applicationdevelopers and system integrators. It manages DC voltages, SIM card, I/O’s,and audios. You can measure several interfaces by pin headers, and thesoftware interfaces of the D9 connectors can be seen and handled. The devicecan be reset with the reset button on the test board PCB.The Nokia 12 module has been type approved with the Nokia 12 test board. Formore information on the Nokia 12 test board, see Appendix: Nokia 12 testboard part list, assembly drawing and schematics.6.1 POWERINGA 3A step down converter is used to produce module V CC . Low ESR capacitorsare used.Table 18. Powering for the Nokia 12 test board6.2 SIM CARD READERThe SIM card reader is directly connected to the M2M System Connector. TheVSIM (pin47) decoupling capacitor must be present in all designs. To see theconnections between the SIM card reader and the M2M System Connector, seeFigure 4.6.3 RS-232 CONVERTERSAll three serial ports of the Nokia 12 module are equipped with RS-232 leveltranslators and D9 connector in the test board. If they are not used, there is aswitch that can be used to set the converters in the Hi-Z mode.28/44

6.4 AUDIOFor testing analog audio, the test board includes a connector for the NokiaHSU-3 handset. The HSU-3 handset can be purchased from Nokia dealers.Figure 10. Nokia 12 test board microphone amplifierThe Nokia 12 test board and its key components are shown in Figure 11.Figure 11. Nokia 12 test board componentsThe Nokia 12 test board includes the following switches:29/44

• RS-232 translator switches for PORT1 and PORT2/PORT3−−When the RS-232 translators are on, PORT1 and PORT2/PORT3 areconnected the Nokia 12 module via the M2M System Connector.When the RS-232 translators are off, PORT1 and PORT2/PORT3 arenot connected the Nokia 12 module via the M2M System Connector.When the RS-232 translators are off, it is possible to establish aconnection to the Nokia 12 module by using the pin headers (1-4).• Microphone input selection switches−−MIC FROM HSU-3 means that microphone signals are routed from theHSU- 3 connector on the testboard to the Nokia 12 module.MIC FROM PIN HEADER means that microphone signals are routed topins 10 and 11 in pin header X100 on testboard edge.• Communication mode switches−−When the switches are in the normal mode position, the BSI line of theNokia 12 module is floating.When the switches are in the AT mode position, a 68 kohm resistor isconnected between the Nokia 12 module BSI line and ground.Note: To use the normal mode/AT mode settings on the test board, theconnection type setting on the Nokia 12 Configurator must be set to ‘HWDetection’. If the connection type setting on the Nokia 12 Configurator is set to‘AT’, the communication mode switch settings on the Nokia 12 test board areoverridden.The use of the switches on the Nokia 12 test board is illustrated in Figure 12.30/44
