Description 2 Security Security IMPORTANT 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.
Description Security If 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 efficiently by following the guidelines below. 2.3 Efficient modem operation In order to operate your modem at the lowest power level, consistent with satisfactory call quality please take note of the following hints.
Description 2.5 Security Driving Check the laws and regulations on the use of cellular devices in the area where you drive. Always obey them. Also, when using your modem 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.
Description Security 2.11 Blasting areas To avoid interfering with blasting operations, turn your unit OFF when in a "blasting area" or in areas posted : „turn off two-way radio“. Construction crew often use remote control RF devices to set off explosives. 2.12 Potentially explosive atmospheres Turn your modem OFF when in any area with a potentially explosive atmosphere. It is rare, but your modem or its accessories could generate sparks.
Description 3 Safety standards Safety standards This 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 protection of public exposure to RF electromagnetic energy established by government bodies and professional organizations, such as directives of the European Community, Directorate General V in matters of radio frequency electromagnetic energy.

Description GPS receiver 6 GPS receiver 6.1 General This 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 satellites in view, thus providing accurate satellite position data.
Description 6.2 GPS receiver Product overview The 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 conditions.
Description GPS receiver Frequency (IF) sampled data to the Scorpio device. The Scorpio device contains an integral microprocessor and all the required GPSspecific signal processing hardware. Memory and other external supporting components configure the GPS receiver into a complete navigation system. 6.2.2 Product applications 6.3 ❐ Automotive applications ❐ Marine navigation applications ❐ Aviation applications ❐ Timing applications Technical description 6.3.
Description GPS receiver ❐ 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) mode A 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.
Description GPS receiver In this state, a portion of the GPS receiver's RF circuitry is de-energized, the SRAMs are transitioned into their low power data retention state, and the RTC device is maintained. When the GPS receiver 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.
Description GPS receiver Symbol Parameter Limits (*) Units VOL (min) Minimum low-level output voltage 0 volts VOL (max) Maximum low-level output voltage 0,2 x PWRIN volts tr, tf Input rise and fall time 50 nanoseconds C out Maximum output load capacitance 25 picofarads (*) PWRIN refers to a + 3,3 V DC power input (PWRIN-3) Table 17: Digital signal requirements Pins 49 and 50: host port serial data input and output (SDO1 and SDI1) The host port consists of a full-duplex asynchronous se
Description GPS receiver 2. 3. If SRAM checksums are invalid and EEPROM checksums are valid, the communication parameters and initialization data parameters will be read from 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.
