Description SecurityA2D–JP Version 1.03 Side 62 SecurityIMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM–MODEM, READ THIS INFORMATION BEFORE USE!Your embedded GSM/GPS–modem is one of the most exciting and innovative electronic products ever developed. With it you can stay in contact with your office, your home, emergency services, and others, wherever service is provided.This chapter contains important information for the safe and reliable use of the GPS receiver. Please read this chapter carefully before starting to use the GPS receiver.2.1 General informationYour modem utilises the GSM standard for cellular technology. GSM is a newer radio frequency („RF“) technology than the current FM technology that has been used for radio communications for deca-des. The GSM standard has been established for use in the Euro-pean community and elsewhere.Your modem is actually a low power radio transmitter and receiver. It sends out and receives radio frequency energy. When you use your modem, the cellular system handling your calls controls both the radio frequency and the power level of your cellular modem.The Global Positioning System uses satellite navigation, an entirely new concept in navigation. GPS has become established in many areas, for example, in civil aviation or deep-sea shipping. It is ma-king deep inroads in vehicle manufacturing, and long before every-one of us will use it in one way or another.The GPS system is operated by the government of the United States of America, which also has sole responsibility for the accuracy and maintenance of the system. The system is constantly being im-proved and may entail modifications effecting the accuracy and per-formance of the GPS equipment.2.2 Exposure to RF energyThere has been some public concern about possible health effects of using GSM modem. Although research on health effects from RF energy has focused for many years on the current RF technology, scientists have begun research regarding newer radio technologies, such as GSM. After existing research had been reviewed, and after compliance to all applicable safety standards had been tested, it has been concluded that the product is fit for use.
Description SecurityA2D–JP Version 1.03 Side 7If you are concerned about exposure to RF energy there are things you can do to minimise exposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In addition, you can reduce RF exposure by operating your cellular modem efficient-ly by following the guidelines below.2.3 Efficient modem operationIn order to operate your modem at the lowest power level, consistent with satisfactory call quality please take note of the following hints.If your modem has an extendible antenna, extend it fully. Some mo-dels allow you to place a call with the antenna retracted. However your modem operates more efficiently with the antenna fully exten-ded.Do not hold the antenna when the modem is „IN USE“. Holding the antenna affects call quality and may cause the modem to operate at a higher power level than needed.2.4 Antenna care and replacementDo not use the modem with a damaged antenna. If a damaged an-tenna comes into contact with the skin, a minor burn may result. Re-place a damaged antenna immediately. Consult your manual to see if you may change the antenna yourself. If so, use only a manufac-turer-approved antenna. Otherwise, have your antenna repaired by a qualified technician.Use only the supplied or approved antenna. Unauthorised anten-nas, modifications or attachments could damage the modem and may contravene local RF emission regulations or invalidate type ap-proval.Operate the GPS receiver with a connected antenna and make sure that there is no obstruction between the receiver and the satellite.Make absolutely sure that the antenna socket or antenna cable is not shorted as this would render the GPS receiver dysfunctional.Do not use the receiver with a damaged antenna. Replace a dama-ged antenna without delay. Use only a manufacturer-approved an-tenna. Use only the supplied or an approved antenna with your GPS receiver. Antennas from other manufacturers which are not authori-zed by the supplier can damage the GPS receiver. Technical modi-fications and additions may contravene local radio-frequency emis-sion regulations or invalidate the type approval.Authorized GPS antennas:FALCOM ANT 006 (active)
Description SecurityA2D–JP Version 1.03 Side 82.5 DrivingCheck the laws and regulations on the use of cellular devices in the area where you drive. Always obey them. Also, when using your mo-dem while driving, please pay full attention to driving, pull off the road and park before making or answering a call if driving conditions so require. When applications are prepared for mobile use they should fulfil road-safety instructions of the current law!2.6 Electronic devicesMost electronic equipment, for example in hospitals and motor ve-hicles is shielded from RF energy. However RF energy may affect some malfunctioning or improperly shielded electronic equipment.2.7 Vehicle electronic equipmentCheck your vehicle manufacturer's representative to determine if any on board electronic equipment is adequately shielded from RF energy.2.8 Medical electronic equipmentConsult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc...) to determine if they are adequately shielded from external RF energy.Turn your modem OFF in health care facilities when any regulations posted in the area instruct you to do so. Hospitals or health care fa-cilities may be using RF monitoring equipment.2.9 AircraftTurn your modem OFF before boarding any aircraft.Use it on the ground only with crew permission.Do not use it in the air.To prevent possible interference with aircraft systems, Federal Avia-tion Administration (FAA) regulations require you to have permissi-on from a crew member to use your modem while the plane is on the ground. To prevent interference with cellular systems, local RF re-gulations prohibit using your modem whilst airborne.2.10 ChildrenDo not allow children to play with your modem. It is not a toy. Chil-dren could hurt themselves or others (by poking themselves or others in the eye with the antenna, for example). Children could da-mage the modem, or make calls that increase your modem bills.
Description SecurityA2D–JP Version 1.03 Side 92.11 Blasting areasTo avoid interfering with blasting operations, turn your unit OFF when in a "blasting area" or in areas posted : „turn off two-way ra-dio“. Construction crew often use remote control RF devices to set off explosives.2.12 Potentially explosive atmospheresTurn your modem OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem or its accessories could ge-nerate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.Areas with a potentially explosive atmosphere are often, but not al-ways, clearly marked. They include fuelling areas such as petrol sta-tions; below decks on boats; fuel or chemical transfer or storage fa-cilities; and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.Do not transport or store flammable gas, liquid, or explosives, in the compartment of your vehicle which contains your modem or acces-sories.Before using your modem in a vehicle powered by liquefied petrole-um gas (such as propane or butane) ensure that the vehicle com-plies with the relevant fire and safety regulations of the country in which the vehicle is to be used.2.13 Non-ionising radiationAs with other mobile radio transmitting equipment users are ad-vised that for satisfactory operation and for the safety of personnel, it is recommended that no part of the human body be allowed to come too close to the antenna during operation of the equipment.The radio equipment shall be connected to the antenna via a non-radiating 50Ohm coaxial cable.The antenna shall be mounted in such a position that no part of the human body will normally rest close to any part of the antenna. It is also recommended to use the equipment not close to medical de-vices as for example hearing aids and pacemakers.
Description Safety standardsA2D–JP Version 1.03 Side 103 Safety standardsThis GSM/GPS-modem complies with all applicable RF safety standards.The embedded GMS/GPS-modem meets the safety standards for RF receivers and the standards and recommendations for the pro-tection of public exposure to RF electromagnetic energy established by government bodies and professional organizations, such as di-rectives of the European Community, Directorate General V in mat-ters of radio frequency electromagnetic energy.

Description GPS receiverA2D–JP Version 1.03 Side 226 GPS receiver6.1 GeneralThis description is focussed on the GPS receiver of the FALCOM JP2 series from FALCOM GmbH. It contains some short information about purpose and use of the GPS receiver. The GPS receiver is a single-board 12 parallel channel receiver intended as a component for OEM Products. The GPS receiver continuously tracks all satelli-tes in view, thus providing accurate satellite position data. The highly in-tegrated digital GPS receiver uses the Zodiac 2000 chip set com-po-sed of two custom CONEXANT devices together with suitable memory devices.Please consult CONEXANT for special information about the GPS Zodiac 2000 chip set.* Signal acquisition performance N/A = Not availableSignal acquisition performanceInitial ERROR uncertainties maximum ephemerisageSatellite acquisition stateTTFF 90 % probable (minutes)position (km) velocity (m/sec) time (min.) hoursWarm 0,40 100 75 5 4Initialised 1,00 100 75 5 4Cold 2,30 N/A* N/A N/A N/AFrozen N/A N/A N/A N/A N/ATable 15: Signal acquisition performanceAccuracyPosition (meter) velocity (meter/sec)horizontal 3-D verticalCEP (2 dRMS)SA off 255093780.1SA on 50 100 (95 %) 200 (95 %) 173 (95 %)Table 16: Accuracy
Description GPS receiverA2D–JP Version 1.03 Side 236.2 Product overviewThe GPS receiver requires conditioned 3,3 V DC power and a GPS signal from a passive or active antenna.The 12 channel architecture provides rapid Time-To-First-Fix (TTFF) under all start-up conditions. As long as visible satellites are not obscured, acquisition is guaranteed under all initialisation con-ditions. To minimise TTFF when main power is removed from the GPS re-ceiver SRAM with external DC supply voltage and EEPROM are used to archive RTC time and prior position data.Communication with the GPS receiver is established through two asynchronous serial I/O ports. The GPS receiver's primary serial port outputs navigation data and accepts commands from OEM ap-plication in NMEA-0183 format or CONEXANT binary format.The secondary port is configured to accept differential GPS (DGPS) corrections in the RTCM SC-104 format.6.2.1 GPS receiver architectureFigure 7: GPS receiver architectureThe functional architecture of the GPS receiver is shown in Figure 7. The GPS receiver design is based on the Conexant Zodiac chip set, the RF-Monopac and the Scorpio DSP, which contain the required GPS functionality. The RF-Monopac contains all the RF down-con-version and amplification circuitry, and presents the In-Phase (I) and Quadrature-Phase (Q) Intermediate.
Description GPS receiverA2D–JP Version 1.03 Side 24Frequency (IF) sampled data to the Scorpio device. The Scorpio de-vice contains an integral microprocessor and all the required GPS-specific signal processing hardware. Memory and other external supporting components configure the GPS receiver into a complete navigation system.6.2.2 Product applications❐Automotive applications❐Marine navigation applications❐Aviation applications❐Timing applications6.3 Technical description6.3.1 General informationSince the GPS receiver determines its position by ranging signals from four or more GPS satellites orbiting the Earth, its antenna must have reasonable visibility of the sky.Navigation modesThe GPS receiver supports three types of navigation mode operati-ons.❐Three dimensional navigation (3D): The GPS receiver defaults to 3-D navigation whenever at least four GPS satelli-tes are being tracked In 3-D navigation, the GPS receiver com-putes latitude, longitude, altitude and time information from satellites measurements.❐Two dimension navigation (2D): When less than four GPS satellite signals are available or when a fixed value of altitude can be used to produce an acceptable navigation solution, the GPS receiver will enter the 2-D navigation mode. Forced ope-rating in 2-D mode can be commanded by the OEM.❐DGPS navigation: The GPS receiver processes DGPS cor-rections through its Auxiliary serial port. These corrections must be compliant with the RTCM recommended standards RTMC-104.Satellites acquisitionThe TTFF of the GPS receiver depends from start conditions.Start condition means if old satellites data are available and how old they are. The conditions are:❐Warm start: results from an short (few minutes) interrupt by continuous navigation. Data are available in SRAM.
Description GPS receiverA2D–JP Version 1.03 Side 25❐Initialised start: is if last known position (in EEPROM) and time are available. Satellite data validity has expired.❐Cold start: means only almanac information is used.❐Frozen start: no valid internal data source available.Built in test (BIT) modeA BIT is available on command from the application software using binary Message 1300. The BIT is used to provide a health status of the GPS receiver functions. Results of the BIT are available in binary Message 1100. A BIT command is possible in NMEA protocol, too.Power modes and power sequencing requirementsThe GPS receiver have three power modes: Off, Operate, and „Keep-Alive“.The Off mode assumes that neither main power is available.In the Operate mode the GPS receiver's components are full supp-lied at 3,3 VDC. The M_RST control signal is at a "high" logic level.From Operate mode, the GPS receiver will enter a "Keep Alive" mode when supply voltage is available at the VBATT signal input and VC3 voltage is removed. VBATT provides power for SRAM and RTC.6.3.2 Hardware interfaceThe following paragraphs describe the basic functions allocated to the various pins on the AMP interface connector. These functions are divided into three groups: Configuration and timing signals, se-rial communication signals, and DC input signals.6.3.2.1 Configuration and timing signalsPin 55: Master reset (M_RST)This signal allows the OEM to generate a system hardware reset to the GPS receiver. This signal is capable of being driven directly by an external microprocessor or by external logic without the need for any external pull-up or pull-down resistors. The OEM can generate a system reset to the GPS receiver by pulling the M_RST control si-gnal low to ground.This signal can also be used to provide control of the GPS receiver's Operate mode without removing prime input power from the GPS re-ceiver. When M_RST is pulled to ground, the GPS receiver will enter a low power state for as long as the M_RST signal is asserted low. The M_RST signal must be pulled to a CMOS logic „high“ level coincident with, or after, the application of prime DC power for the receiver to enter its Operate mode. The M_RST must be held at ground level for a minimum of 150 nanoseconds to assure proper generation of a hardware reset to the receiver.
Description GPS receiverA2D–JP Version 1.03 Side 26In this state, a portion of the GPS receiver's RF circuitry is de-ener-gized, the SRAMs are transitioned into their low power data reten-tion state, and the RTC device is maintained. When the GPS recei-ver is placed into this low power state through the use of the M_RST control signal, the GPS receiver will continue to draw current from the primary input power (PWRIN) but at a reduced level.When the M_RST signal is subsequently asserted high by the OEM, RF power is re-applied, a system reset is generated, and the GPS receiver will return to its normal Operate mode.Pins 56, 53, 54 and 51: General Purpose I/O (GPIO1, GPIO2, GPIO3 and GPIO4)The GPS receiver provides four General Purpose Input/Output (GPIO) connections that are available for use by the OEM.These GPIO connections are digital interfaces that are OEM soft-ware programmable as inputs or outputs.Pin 41: UTC Time Mark Pulse (TMARK)The Time Mark output provides a one pulse-per-second (1 pps) signal to the OEM application processor. When the GPS receiver provides a valid navigation solution, the rising edge of each TMARK pulse is synchronized with the UTC one second epochs to within ±300 nsec.Pin 42: 10 kHz UTC synchronized clockThis is a 10 kHz clock waveform that is synchronized to the UTC TMARK pulse.This clock signal is a positive logic, buffered CMOS level output.6.3.3 Serial communication signalsSymbol Parameter Limits (*) UnitsPWRIN 3 Main power input to the JP2 (+3,3 V DC) 3,135 to 3,465 voltsVIH (min) Minimum high-level input voltage 0.7 x PWRIN voltsVIH (max) Maximum high-level input voltage PWRIN voltsVIL (min) Minimum low-level input voltage - 0,3 voltsVIL (max) Maximum low-level input voltage 0,3 x PWRIN voltsVOH (min) Minimum high-level output voltage 0,8 x PWRIN voltsVOH (max) Maximum high-level output voltage PWRIN voltsTable 17: Digital signal requirementsBoth the configuration and timing signals, described in the previous section, and the serial communication signals described below must be applied according to the limits shown in table 17.
Description GPS receiverA2D–JP Version 1.03 Side 27Pins 49 and 50: host port serial data input and output (SDO1 and SDI1)The host port consists of a full-duplex asynchronous serial data in-terface. Both binary and NMEA initialization and configuration data messages are transmitted and received across this port.The default ROM settings for the host serial data port are binary message format, 9600 baud, no parity, 8 data bits, and 1 stop bit. The default may be modified using custom OEM software.The serial port settings may also be changed to a new configuration using binary serial message 1330. The new serial port settings are stored in SRAM and serial EEPROM. The next time the GPS recei-ver is powered on or a master reset is initiated, the serial port confi-guration parameters are accessed in the following priority:1. If SRAM checksums are valid, the communication parameters and initialization data parameters will be read from SRAM.2. If SRAM checksums are invalid and EEPROM checksums are valid, the communication parameters and initialization data parameters will be read from EEPROM.3. If SRAM checksums are invalid and EEPROM checksums are invalid, the default values in ROM will be used.The OEM application must provide any Line Driver/Line Receiver (LD/LR) circuitry to extend the range of the interface.Port Idle is nominally a CMOS logical high (+ 3,3 V DC).Pin 45 and 48: Auxiliary port serial data (SDI2 and SDO2)The auxiliary port consists of a second half-duplex asynchronous serial data interface. This port is configured to receive RTCM DGPS correction data messages.The default ROM settings for the Auxiliary Serial Data Port are 9600 baud, no parity, 8 data bits, and 1 stop bit. The default may be mo-dified using custom OEM software.The serial port settings may also be changed to a new configuration using binary serial message 1330. The new serial port settings are stored in SRAM and serial EEPROM.

If SRAM checksums are invalid and EEPROM checksums are invalid, the default values in ROM will be used.The OEM application must provide any LD/LR circuitry to extend the range of the interface. Port Idle is nominally a CMOS logical high (+ 3,3 V DC).6.3.4 DC input signalsPin 59: Preamp power input (PREAMP)The OEM may optionally supply power to a preamplifier using the antenna cable center conductor. The maximum voltage is +12 V DC and the current must not exceed 100 mA.Pins 58 and 60: Power input (PWRIN 3)This signal is the main power input to the GPS receiver.Regulated DC power requirements are shown in table 2.Pin 57: Battery backup power input (VBATT)This signal is used to provide a DC power input to the SRAM and RTC devices only. The GPS receiver automatically switches to the VBATT input signal when primary DC power (PWRIN) is removed from the board.This feature is intended to provide the GPS receiver with a "warm start" capability by maintaining an accurate time source and using position and satellite data stored in SRAM after prime input power (PWRIN) has been removed from the GPS receiver.Pins 43, 44, 46, 47 and 52: Ground (GND)DC grounds for the board. All grounds are tied together through the GPS receiver's printed wiring board (PWB) ground plane and should all be grounded externally to the GPS receiver.6.3.5 Software interfaceThe host serial I/O port of the GPS receiver serial data interface sup-ports full duplex communication between the GPS receiver and the OEM application. Data messages can be in the Conexant binary for-mat or NMEA-01 83 format. The GPS receiver also contains an auxiliary port dedicated to direct processing of the RTCM SC-104 messages for DGPS corrections.Do not apply power to a passive antenna or damage to the receiver will occur.!
