1 Overview10 CrossCheck GSM/GPRS 850/1900 Installation Manual1.3 CrossCheck GSM/GPRS ApplicationsThe Trimble Mobile Solutions (TMS) division provides a set of core products, around which you can build systems and applications for managing your transport and logistics assets. TMS products and services provide the building blocks at both ends of the asset management system, including the on-board units mounted in the vehicle and the Telvisant Web-based gateway for dispatch and control applications.The central on-board component is the CrossCheck GSM/GPRS unit. You can use the unit as a standalone unit, or interface it with external accessories and sensors to make it function as part of an on-board system. The optional EchoLDX Message Terminal provides a driver interface for exchanging messages and generating event reports.The CrossCheck GSM/GPRS and applications can do the following:• Automate vehicle status changes for dispatching applications.• Determine time spent and distance traveled on jobs for accounts-payable systems.• Improve efficiency by detecting unauthorized vehicle stops or off-route activities.• Improve customer service by advising customer service systems of delays.• Drive compliance by keeping a time-stamped log of activities.• Improve safety by indicating speed limit violations.• Identify unauthorized use of equipment and detect theft.
CrossCheck GSM/GPRS 850/1900 Installation Manual 11Overview 11.4 The Global Positioning SystemThe Global Positioning System (GPS) is a satellite-based navigation system operated and maintained by the U.S. Department of Defense. GPS consists of a constellation of 24 satellites providing world-wide, 24-hour, three-dimensional (3D) coverage. Although originally conceived for military needs, GPS has a broad array of civilian applications including timing, surveying, fleet management, marine, land, aviation, and vehicle navigation. As a satellite-based system, GPS is free from the limitations of land-based systems, which have limited coverage and whose accuracy varies with geographic location.A GPS receiver calculates an accurate position by computing its distance from GPS satellites orbiting the earth. This process is called satellite ranging. A GPS receiver can also provide precise time, speed, and course measurements, which are important for vehicle mobile positioning and communications applications. 1.5 GPS ReceiverThe CrossCheck GSM/GPRS unit includes an advanced GPS receiver, which provides the position, course, speed, and time information required for AVL and fleet management applications.The integrated GPS receiver in the CrossCheck GSM/GPRS unit features an eight-channel digital signal processor which operates at the GPS L1 frequency (1575.42 MHz) and processes the Coarse/Acquisition (C/A) code portion of the GPS signal. The RF and digital signal-processing components of the GPS module are custom integrated circuits designed by Trimble.

When selecting a mounting location, consider the specifications listed in Appendix A, and avoid the following hazards:• Direct exposure to weather• Excessive heat (exhaust manifolds)• Excessive cold (refrigeration units)• High-vibration areas (engine compartment, transmission)• Corrosive fluids and gases (acids, petroleum products)• Direct exposure to water (the CrossCheck GSM/GPRS is not waterproof)• Areas where there is excessive dustChoose a location that:• allows for convenient routing and connection of the antenna and interface cables• has access to a power source• allows you to see the LED indicators. During normal system operation, you do not need to see the LED indicators, but they do provide valuable information if you are troubleshooting.• is reasonably flat. The mounting flange is designed to secure the CrossCheck GSM/GPRS unit to a flat surface.
CrossCheck GSM/GPRS 850/1900 Installation Manual 21Installation 22.5.2 Mounting the CrossCheck GSM/GPRS unitThe mounting flange has four holes for securing the unit to the flat surface. Use self-tapping screws or machine screws to secure the CrossCheck GSM/GPRS unit to the mounting surface. CCaution – Do not fasten the mounting screws too tightly. This can over-stress the plastic mounting surface and crack the plastic. The mounting surface can also become compressed, cracked, or deformed if you do not use washers, or if you use washers that are too big so that they tighten down on the plastic cover of the CrossCheck GSM/GPRS unit when the mounting screws are secured.Figure 2.4 shows the mounting dimensions. The hole size leaves some allowance for holes that are drilled slightly off center from the specified dimensions.Figure 2.4 Mounting dimensions4.8 205.5 mm69.9 mm(8 in)(2.75 in)(0.18 in)mm
2 Installation22 CrossCheck GSM/GPRS 850/1900 Installation ManualYou must provide appropriate fasteners (either self-tapping screws or machine screws) for securing the CrossCheck GSM/GPRS unit to the mounting surface.If you use self-tapping screws, select an appropriate size and length for the mounting surface.If you use machine screws:• It is recommended that you use number m3.5 (or #6) pan-head machine screws.• Select a screw that is long enough to extend a safe distance beyond the mounting surface.• Secure the screw with a washer and a nut. It is recommended that you use lock washers to prevent the vehicle’s vibration from loosening the fasteners.2.5.3 Grounding the CrossCheck GSM/GPRS unitFor proper operation, the aluminum body of the CrossCheck GSM/GPRS unit must be connected electrically (grounded) to the chassis of the vehicle on which it installed. This can be accomplished in two ways:• Direct connection through metal screws. This is the recommended method.• Connection through the chassis ground wire.Direct connection through mounting screwsIf possible, ground the CrossCheck GSM/GPRS unit by mounting it on a metal surface that is permanently attached to the vehicle chassis. For example, mount the unit on the base of the trunk, or on a mounting plate that is permanently attached to the chassis. Fasten the CrossCheck GSM/GPRS unit to the mounting surface using metal screws driven through the metal tabs on the sides of the unit. Use star washers to ensure a reliable electrical contact with the metal
CrossCheck GSM/GPRS 850/1900 Installation Manual 23Installation 2tabs. Make sure that the screws are tight, and that they make contact both with the metal on the CrossCheck GSM/GPRS unit and with the vehicle chassis.Note – If you use this method to connect the CrossCheck GSM/GPRS unit to the vehicle chassis, leave the chassis ground (pin 3 on the power and discrete I/O connector) on the CrossCheck GSM/GPRS unit unconnected.Note – Make sure that the vehicle chassis is properly grounded in the vehicle.Connection through the chassis ground wireIf the CrossCheck GSM/GPRS unit cannot be mounted directly on a metal surface when it is attached to the vehicle, then use the chassis ground wire (pin 3 on the power and discrete I/O connector) to make electrical contact with the vehicle chassis. Use a wire with gauge of at least 20 AWG to connect the CrossCheck GSM/GPRS unit power connector to the vehicle chassis. To keep the wire as short as possible, select a connection point on the vehicle chassis that is close to the CrossCheck GSM/GPRS unit. Use a metal screw with a star washer to ensure a reliable electrical contact to the vehicle chassis.2.6 Installing the GPS AntennaTo install the GPS antenna, you must carefully choose a mounting location, mount the antenna, and then route the antenna cable to the CrossCheck GSM/GPRS.2.6.1 Choosing a location for the GPS antennaAntenna location is critical for optimum GPS performance. When choosing a location for the GPS antenna, make sure that the antenna:• has an unobstructed view of the sky
2 Installation24 CrossCheck GSM/GPRS 850/1900 Installation Manual• is safe from damage during normal vehicle operation and maintenance• is not shielded from satellite signals by metal objects or other impenetrable materialsGPS signals can penetrate plastic, glass (including tinted glass), fiberglass, and plexiglass, provided the surface is relatively dry. GPS signals do not penetrate metal, metallized glass, or dense wood.For optimum performance, the GPS antenna should be mounted on a metal groundplane of at least 7.5 cm square (3" × 3") only if it is not mounted on a metal surface.If necessary, you can install the GPS antenna on a dashboard under a sloped windshield (provided the windshield is not metallized), or under a plastic fender or bumper. When the antenna is installed in one of these locations, the metal components of the vehicle shield the antenna from portions of the sky, so these alternative locations usually offer less satellite coverage.CCaution – Do not mount the GPS antenna under a metallized glass windshield, such as those used in some vehicles for window de-fogging or de-icing systems.Disclaimer – The guidelines included in this section apply to the GPS antennas sold by Trimble and may not apply to third-party products. There are many other GPS antennas on the market, including combined GPS/cellular antenna solutions. These antennas have not been tested or certified by Trimble, and may not be compatible with the CrossCheck GSM/GPRS.Additional guidelines to follow include:• Mount the antenna in a horizontal position facing the sky, as shown in Figure 2.5.• Locate the GPS antenna at least 46 cm (approximately 18") from any other antennas, such as radio or cellular phone antennas.
CrossCheck GSM/GPRS 850/1900 Installation Manual 25Installation 2• Avoid areas of high vibration, such as engine hoods.• A heavy layer of snow or ice can degrade the performance of the GPS antenna. If these are typical conditions for your application, choose an accessible mounting location, so that snow and ice can be removed easily.• For permanent installations, choose a location that allows access both above and below the antenna mounting surface. This access is required for installing fasteners and for routing the antenna cable.• Make sure that the antenna cable will reach from the CrossCheck GSM/GPRS unit to the antenna mounting location. The standard length of GPS antenna cables supplied by Trimble is 5 m (approximately 16 ft). You can prepare longer bulkhead-mount antenna cables using the guidelines in Appendix A, Specifications.Figure 2.5 shows typical antenna mounting locations for a car.Figure 2.5 Antenna mounting locations for a carBest Performance Reduced Performance

2 Installation50 CrossCheck GSM/GPRS 850/1900 Installation Manual2.7.3 Routing the cellular antenna cableThe next step in the installation process is routing and connecting the antenna cable to the CrossCheck GSM/GPRS unit. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck GSM/GPRS unit, while avoiding the following hazards:• Excess coils in the antenna cable, particularly the cellular antenna cable. A coiled cable can act as an antenna and may receive interference.• Pinching the cable in a hinged door. Provide an adequate service loop when routing the cable around vehicle hinges.• Vehicle movement that might cause cable damage. Make sure that the coaxial cable is not routed through areas where vehicle movement can abrade the cable surface. • Exposure to environmental damage. If your cellular antenna cable is exposed to the environment, use tie wraps to secure the cellular antenna cable along its route to prevent wind damage. Connecting the magnetic cellular antenna cableThe magnetic cellular antenna has a 3.65 m (12 ft) integrated antenna cable with a TNC-plug (TNC-p) connector. After routing and securing the magnetic cellular antenna cable, connect the cable to the TNC connector on the CrossCheck GSM/GPRS. Tighten the connector firmly to prevent loosening caused by normal vehicle vibration.Connecting the bulkhead or glass mount cellular cableThe bulkhead cellular antenna has a 5.1 m (17 ft) integrated cable, and the glass mount cellular antenna has a 4.5 m (15 ft) integrated cable. Neither cable is terminated with a connector. After routing and securing the bulkhead cellular or glass cellular cable, attach the TNC-p connector to the antenna cable. Then attach the cable to the TNC connector on the front panel of the CrossCheck GSM/GPRS unit. For instructions on how to install the TNC-p connector, see page 45.
CrossCheck GSM/GPRS 850/1900 Installation Manual 51Installation 22.8 CrossCheck GPRS PowerThe CrossCheck GSM/GPRS unit operates on input voltages from 9 V DC to 32 V DC. The low-noise amplifier integrated on the GPS antenna draws power from the CrossCheck GSM/GPRS unit through the antenna cable. The CrossCheck GSM/GPRS unit does not require any special power-up or power-down sequencing. The CrossCheck GSM/GPRS unit’s power circuitry protects the unit from random power fluctuations. The unit’s input circuits protect it against transient voltage spikes found in most automobile and truck environments. External fuses protect against excessive current.For more information on the CrossCheck GSM/GPRS unit power requirements, see Appendix A, Specifications.

CrossCheck GSM/GPRS 850/1900 Installation Manual 53Installation 2CCaution – You must install a 2A fuse in the CrossCheck GSM/GPRS power cable in the Vbatt and IGN line. Two 2A fuse and fuse holders are supplied with the power/data cable (P/N 46598). Install the fuse holders and fuses as close as possible to the vehicle battery and ignition switch respectfully.The DC ground line connects to the vehicle’s DC ground. If the ignition-sense lead is connected to a source of ignition-switched battery voltage, it senses when the vehicle’s ignition is active. There are two main connection options for connecting the power, ground, and ignition-sense wires:• Power Management• Continuous PowerThese options are described in the following sections.2.8.1 Power Management optionWhen the CrossCheck GSM/GPRS unit is connected using the Power Management option, it operates continuously only when the vehicle ignition is on. When the ignition is off, the CrossCheck GSM/GPRS unit goes into Sleep mode and draws reduced power. For more information on the current drawn in different operation modes, see Appendix A, Specifications. By default, when the Power Management option is enabled, the CrossCheck GSM/GPRS goes into Sleep mode 15 minutes after it detects that the ignition has been turned off. If the EchoLDX is connected to the CrossCheck, the EchoLDX turns off one minute after the CrossCheck detects that the ignition has been turned off.

CrossCheck GSM/GPRS 850/1900 Installation Manual 55Installation 22.8.2 Continuous Power optionWhen the CrossCheck GSM/GPRS unit is connected using the Continuous Power option, it draws power continuously, even when the vehicle is not running. Typical power consumption in idle mode (when the unit is not transmitting) at 12 V DC is 90 mA without the EchoLDX terminal, and 160 mA with the EchoLDX terminal.CCaution – When connected to the vehicle’s battery using the Continuous Power option, the CrossCheck GSM/GPRS unit may drain the battery if the vehicle is not running for several days. The time to drain the battery is 1 to 3 weeks, depending on the battery size, quality, and remaining life span. If the CrossCheck GSM/GPRS unit is connected using the Continuous Power option, it can also drain the battery of a vehicle that is not running long enough to compensate for the current draw of the CrossCheck. Observe extreme care when using this connection option. The CrossCheck GSM/GPRS unit will automatically power off when the voltage drops below 9 V DC.

CrossCheck GSM/GPRS 850/1900 Installation Manual 59Installation 22.9.1 Inputs (IP0 to IP3)The CrossCheck GSM/GPRS unit supports four discrete inputs. Figure 2.28 shows the circuit diagram.Figure 2.28 Input circuit diagramFor input specifications, see Table A.16 on page 80.Each input floats to a logic-high state (inactive) when left open. Grounding an input causes a logic-low state (active). The CrossCheck GSM/GPRS unit can be configured to detect either logic-high or logic-low states at the inputs whenever the unit is switched on. Note – When the CrossCheck GSM/GPRS unit is switched off or in Sleep mode, it can only detect a logic-low (grounded) input. The internal input circuitry incorporates a resistor-capacitor network on the input. This filters noise to avoid triggering on very short pulses. The discrete inputs are compatible with properly connected relays and switches, and with standard 3.3 V DC logic levels. A properly connected relay or switch allows the input to float high in one position and grounds the input in the other position. 3K330K0.01µFTo logic470pfInput 100K3.3V

In the active state, the outputs can sink up to 200 mA. Figure 2.30 shows a diagram of a discrete output.Figure 2.30 Output circuit diagramFor output specifications, see Table A.18 on page 81.2.9.4 Message Terminal Port (DB9 receptacle)The Message Terminal Port is a serial RS-232 port for messaging communication with the optional EchoLDX Message Terminal Kit (P/N 46722-00).15K36V 0.01µF0.2A470pfOutputVbatt

3 Operation64 CrossCheck GSM/GPRS 850/1900 Installation Manual3.1 IntroductionOnce you have installed and configured the CrossCheck GSM/GPRS unit, it is ready for operation. When power is applied, the CrossCheck GSM/GPRS unit operates automatically without user intervention.This chapter provides a basic overview of how the CrossCheck GSM/GPRS unit operates.3.2 LED IndicatorsThe CrossCheck GSM/GPRS unit has two LED indicators, as shown in Figure 3.1. These LEDs provide feedback on the status of the integrated GPS receiver and GPRS cellular transceiver, which the CrossCheck GSM/GPRS unit firmware monitors continuously.Figure 3.1 LED indicatorsGPS LED (Green)GPRS LED (Amber)
CrossCheck GSM/GPRS 850/1900 Installation Manual 65Operation 3The GPS and GPRS LED indicators have three states: on, off, and flash. When both indicators are off, the CrossCheck GSM/GPRS unit’s power is off. When one or both LED indicators are on or flashing, the power is on.3.2.1 LED statesTable 3.1 identifies the GPS LED states.Table 3.2 identifies the GPRS LED states.3.2.2 LED power-on sequenceWhen the CrossCheck GSM/GPRS unit’s ignition and power inputs are activated:Table 3.1 GPS (green) LED statesState MeaningOn Computing GPS position fixes.Flash Searching, or not computing GPS position fixes.Off No power is available, or the ignition is off.Table 3.2 GPRS (amber) LED statesState MeaningOn GPRS coverage is available and the CrossCheck GSM/GPRS unit is registered with the appropriate GPRS network.Slow flash The first three minutes after power up, indicates that the unit is searching for a GPRS network. If the LED continues to flash, it either means that there no GPRS coverage is available, or the CrossCheck GSM/GPRS unit is not registered with the local network.Fast flash SIM card is not inserted correctly, is missing, or it is protected by a PIN.Off No power is available, or the ignition is off.
3 Operation66 CrossCheck GSM/GPRS 850/1900 Installation Manual• The GPS LED flashes once, turns off for approximately five seconds, then turns on for approximately two seconds, flashes until the first position fix is computed, then stays on.• The GPRS LED flashes once, turns off for approximately five seconds, flashes until the unit is registered with a GPRS network, then stays on.3.3 GPS Receiver OperationWhen the CrossCheck GSM/GPRS unit is powered on, the GPS receiver initializes with the last known position if one is available. Using this information, the GPS receiver acquires satellite signals.During the satellite acquisition process—which normally takes less than 45 seconds—the green GPS LED flashes. Once a sufficient number of satellites have been acquired, the GPS receiver computes positions, course, and speed, and the green GPS LED stays on. When the GPS LED is flashing, it indicates that the GPS receiver is not tracking enough satellites to calculate a current position. This occurs occasionally when the vehicle is obscured from satellite signals by terrain, buildings, trees, tunnels, or other structures. During this period, called satellite reacquisition, the GPS receiver continuously searches for the obscured satellites and expands its search to other satellites to continue position computations. For brief blockages, the GPS receiver normally reacquires a lost satellite signal and resumes position fixes in less than two seconds.Note – If the CrossCheck GSM/GPRS unit does not have a valid last known position, the unit performs a cold start. A cold start normally takes less than three minutes. This happens the first time the unit is turned on, or if the unit has never been on long enough to obtain a complete almanac. To obtain an initial almanac, the unit must track GPS satellites for up to 30 minutes.
CrossCheck GSM/GPRS 850/1900 Installation Manual 67Operation 33.4 RegistrationWhen the CrossCheck GSM/GPRS unit is turned on, it checks whether a SIM card is installed. If a SIM card is not detected or has not been installed properly, the amber LED flashes rapidly. If a SIM card is installed, the unit tries to register with the appropriate GPRS network. If the unit cannot detect a GPRS network, the amber GPRS LED flashes slowly. Once the CrossCheck detects a GPRS network, it begins the registration process to get a dynamic IP (Internet Protocol) address from the GPRS network provider. This IP address is used for the CrossCheck GSM/GPRS unit until it is turned off. When the CrossCheck GSM/GPRS unit has successfully registered with the network, the amber GPRS LED stays on. The CrossCheck GSM/GPRS unit then establishes communication with the Telvisant platform, indicating its new IP address and location (if available). If the EchoLDX messaging terminal is installed, an antenna symbol appears in the left corner of the EchoLDX display whenever the CrossCheck GSM/GPRS unit is connected to the Telvisant Wireless Gateway.When the vehicle is stopped or parked and the ignition is turned off, the CrossCheck GSM/GPRS unit remains connected to the network for a specific period. After that period the unit disconnects from the GPRS network and turns itself off. When it is turned on again, the unit establishes a new GPRS connection.Occasionally the vehicle may enter an area that does not have GPRS coverage. If the CrossCheck GSM/GPRS unit is connected to a GPRS network when this happens, the amber GPRS LED flashes slowly. When the unit returns to an area with GPS coverage, it establishes a new GPRS connection.
