CrossCheck GPRS 1900 Installation Manual 7Overview 11.3 CrossCheck GPRS ApplicationsThe Trimble Mobile Solutions (TMS) Division provides you with the core products around which you can build systems and applications for managing your transport and logistics assets. TMS products and services address the need for an end-to-end solution. They provide the building blocks at both ends of the asset management system including the on-board units mounted in the vehicle and the Trimble Web-based gateway for dispatch and control applications anywhere.The on-board components are centered on the CrossCheck GPRS receiver. You can use the receiver as a standalone unit, or you can 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 to exchange messages or generate event reports.The CrossCheck 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 alerting 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
1 Overview8 CrossCheck GPRS 1900 Installation Manual1.4 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.GPS is the most accurate technology available for navigation. As a satellite-based system, GPS is immune from the limitations of land-based systems, which have limited coverage and whose accuracy varies with geographic location and, even under ideal conditions, cannot compare with GPS.By computing the distance to GPS satellites orbiting the earth, a GPS receiver can calculate an accurate position. This process is called satellite ranging. GPS receivers can also provide precise time, speed, and course measurements which are important for vehicle mobile positioning and communications applications. 1.5 GPS ReceiverThe CrossCheck GPRS includes an advanced GPS receiver, which provides the position, course, speed and time information required for AVL and fleet management applications. A brief overview of the GPS receiver’s architecture and operation is provided in the next paragraph.The CrossCheck GPRS’s GPS receiver features an eight-channel digital signal processor (DSP) 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.

2 Installation16 CrossCheck GPRS 1900 Installation Manual2.6 Mounting the CrossCheck GPRSThe CrossCheck GPRS can be installed inside almost any type of vehicle and in any orientation. It can be installed in an enclosed compartment or in a location with limited accessibility, as long as the environmental specifications are maintained to ensure reliable operation. For example, the CrossCheck GPRS can be installed on the floor under a seat, or on a wall behind a seat.Note – The CrossCheck GPRS cannot be installed inside the engine compartment, wheel well, chassis, or on any exterior surface of the vehicle.Choose a location for the CrossCheck GPRS that allows for convenient routing and connection of the antenna and interface cables, and that has access to a power source. 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 GPRS is not waterproof.)• Areas where excessive dust will be presentTo mount the CrossCheck GPRS:1. Choose the mounting location.The CrossCheck GPRS can be mounted horizontally, vertically, or in any convenient orientation. During normal system operation, you do not need to see the CrossCheck GPRS LED indicators. However, the ability to see the LED indicators is a definite advantage when troubleshooting the unit.
CrossCheck GPRS 1900 Installation Manual 17Installation 2The integral mounting flange is designed to secure the CrossCheck GPRS to a flat surface. The flange has four holes for securing the unit with fasteners.2. Use self-tapping screws or machine screws to secure the unit to the mounting surface.ICaution – Over-stressing the plastic mounting surface when tightening the mounting screws can crack the plastic. Use washers sized small enough that they do not tighten down on the plastic cover of the CrossCheck GPRS when the mounting screws are secured. Tightening screws without using washers can lead to compressing, cracking, or deforming the mounting surface.Figure 2.4 shows the mounting dimensions.Figure 2.4 CrossCheck GPRS Mounting Dimensions4.8 205.5 mm69.9 mm(8 in)(2.75 in)(0.18 in)mm
2 Installation18 CrossCheck GPRS 1900 Installation ManualThe installer must provide an appropriate selection of fasteners to secure the CrossCheck GPRS to the mounting surface.• When using self-tapping screws:– Select an appropriate size and length for the mounting surface. – The hole size leaves some allowance for holes drilled slightly off center from the specified dimensions.• When using machine screws:– Trimble recommends the use of number m3.5 (or number 6) pan-head machine screws.– Select a screw length, which extends a safe distance beyond the mounting surface.– Secure the screw with a washer and nut. Lock washers are recommended to prevent vehicle vibration from loosening the fasteners.2.6.1 Connecting CrossCheck GPRS to the Vehicle ChassisFor proper operation, the aluminum chassis of the CrossCheck GPRS 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 (preferred)• Connection through the chassis ground wire
CrossCheck GPRS 1900 Installation Manual 19Installation 2Direct Connection through Mounting ScrewsTo mount the CrossCheck GPRS 1900 Mobile Unit on a metal surface that is permanently attached to the vehicle chassis (for example, the base of the trunk, or a mounting plate that is permanently attached to the chassis using metal screws):1. Fasten down the CrossCheck GPRS using metal screws driven through the metal tabs on the sides of the unit.2. Use star washers to ensure a reliable electrical contact to the metal tabs.3. Make sure the screws are tight, and that they make contact both with the metal on the CrossCheck GPRS and with the vehicle chassis.Note – If this direct connection through mounting screws method is used for chassis connection, then the chassis ground (pin 3 on the power and discrete I/O connector) on the CrossCheck GPRS should be left unconnected.Connection through the Chassis Ground WireIf the CrossCheck GPRS cannot be mounted directly on a metal surface that 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 to the vehicle chassis:1. Use a wire with gauge of at least 20 AWG to connect the CrossCheck GPRS power connector to the vehicle chassis.2. Use a metal screw with a star washer to ensure a reliable electrical contact to the vehicle chassis.3. Keep the wire length as short as possible by selecting a connection point in the vehicle chassis that is close to the CrossCheck GPRS.
2 Installation20 CrossCheck GPRS 1900 Installation Manual2.7 Choosing the GPS Antenna Mounting LocationAntenna location is critical for optimum GPS performance. When choosing a location for the GPS antenna, consider these guidelines:• The antenna has an unobstructed view of the sky.• The antenna is safe from damage during normal vehicle operation and maintenance.• The antenna is not shielded from satellite signals by metal objects or other impenetrable materials.GPS signals can penetrate plastic, glass and tinted glass (except metallized glass), fiberglass, and plexiglass materials as long as the surface is relatively dry. GPS satellite signals do not penetrate metal or dense wood. Since GPS satellite signals can penetrate plastic, fiberglass, and glass, the GPS antenna can also be installed on a dashboard under a sloped windshield (if the windshield is not metallized) or under a plastic fender or bumper. These alternative locations are likely to offer less satellite coverage, since the metal components of the vehicle shield the antenna from portions of the sky.For optimum performance, the GPS antenna should be mounted on a metal groundplane of at least 7.5 cm square (3 in. x 3 in.).ICaution – 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. However, the GPS antenna can be mounted under a tinted-glass windshield.Disclaimer - The instructions 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 available on the market which may or may not be compatible with the CrossCheck GPRS, including combined GPS/GSM cellular antenna solutions which have not been tested or certified by Trimble.
CrossCheck GPRS 1900 Installation Manual 21Installation 2Additional guidelines to follow include:• Mount the antenna in a horizontal position facing the sky, as shown in Figure 2.5.If the antenna must be located in the vicinity of other antennas (radio, cellular phone), locate the GPS antenna at least 46 cm (approximately 18 in.) away.• Avoid areas of high vibration (for example, engine hoods).For permanent installations, choose a location with access both above and below the antenna-mounting surface. This access is required for installing fasteners and for routing the antenna cable.Note – The standard length of magnetic-mount and bulkhead-mount GPS antenna cables supplied by Trimble is 5 m (approximately 16 ft.). Longer bulkhead-mount antenna cables can be prepared by the installer using the guidelines presented in Appendix A.

2 Installation30 CrossCheck GPRS 1900 Installation Manual2.8 Routing the GPS Antenna CableThe Magnetic GPS Antenna has an integral antenna cable, and the Miniature Bulkhead GPS Antennas have separate cables.If you are using one of the Miniature Bulkhead GPS Antennas, attach the antenna cable to the connector on the base of the antenna prior to routing the cable. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck GPRS while observing the following guidelines:• Make sure that at least 5.1 cm (2 in.) of clearance exists between the CrossCheck GPRS's antenna connector and the nearest obstacle.• Make all cable bends, especially the bend at the SMA strain relief to the antenna connector, with at least 1.3 cm (1 in.) bend radius.• Provide an adequate service loop when routing the cable around vehicle hinges to ensure that the cable is not pinched when a hinged door opens or closes.• Make sure that the coax cable is not routed through areas where vehicle movement can abrade the cable surface.• Never coil the excess antenna cable, particularly the Magnetic GPS antenna cable. A coiled cable can act as an antenna and cause interference problems.• Protect cables from exposure to corrosive fluids.Once the cable is routed and secured, attach the cable to the CrossCheck GPRS GPS (SMA) connector.
CrossCheck GPRS 1900 Installation Manual 31Installation 22.9 Choosing a GPRS Cellular Antenna Mounting LocationCWarning – The CrossCheck GPRS and its antennas and accessories should only be professionally installed by Trimble Authorized dealers.Warning – For 1900 MHz PCS:A minimum separation distance of 20 cm must be maintained between the antenna and the person for this device to satisfy the RF exposure requirements of the FCC. For fixed-mount operation, the antenna co-location requirements of Section 1.1307 (b) (3) of the FCC rules must be satisfied. The maximum antenna gain, including any cable loss, must not exceed 3dBi.Warning – Portable operation of this unit is not permitted.Disclaimer - The instructions included in this section apply to the cellular antennas sold by Trimble and may not apply to third-party products. There are many other cellular antennas available on the market which may or may not be compatible with the CrossCheck GPRS, including combined GPS/Cellular antenna solutions which have not been tested or certified by Trimble. Mount the cellular whip antenna in a vertical orientation in a location where it is safe from damage during normal vehicle operation and maintenance. Automated vehicle washes may damage misplaced cellular antennas.
2 Installation32 CrossCheck GPRS 1900 Installation ManualMaintain a separation of at least 46 cm (or approximately 18 in.) between the cellular (or other) and GPS antennas (as illustrated in Figure 2.12). Figure 2.12 Distance Between Antenna LocationsIn general, the greater the separation, the less chance of interference. For permanent antenna installations, choose a location with access both above and below the antenna mounting surface. This access is required for installing fasteners and for routing the antenna cable.Cellular phone dealers and installers are experts on cellular antenna placement. For some installations, the installer may substitute a glass-mount antenna for the antenna supplied by Trimble. Other antennas are acceptable as long as they conform to the requirements listed in Appendix A.Trimble offers three cellular antenna options for the CrossCheck GPRS.

The Bulkhead Cellular antenna has a 5.1 m (17 ft.) integral cable and the Glass Mount Cellular antenna has a 4.5 m (15 ft.) integral cable; both cables are terminated without a connector. After routing the Bulkhead Cellular or Glass Cellular cable, it must be fitted with a TNC-p connector before attaching the cable to the CrossCheck GPRS. Instructions for installing the TNC-p connector are included with the antenna kit.The next step in the installation process is routing and connecting the antenna cable to the CrossCheck GPRS. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck GPRS 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 coax 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.

The circuit diagram is shown in Figure 2.23.Figure 2.23 Input Circuit DiagramEach input floats to a logic-high state (inactive) when left open. Grounding an input causes a logic-low state (active). The CrossCheck GPRS can be configured to detect either logic-high or logic-low states at the inputs whenever the unit is powered on. Note – When the CrossCheck GPRS is powered off or in Power Management mode, it can only detect a logic-low (grounded) input. The discrete inputs are compatible with properly connected relays and switches or with standard 3.3 VDC 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. Input Logic High: Open circuit or Vin > 2.4 VDCInput Logic Low: Vin < 0.8 VDCThe inputs must remain in either state for at least 500 milliseconds before the CrossCheck GPRS detects the input.Input Current (Max) < 1 mA at 12 VDCInput Protection: Protected up to at least Vbatt continuous 3K330K0.01µFTo logic470pfInput 100K3.3V

2 Installation52 CrossCheck GPRS 1900 Installation Manual2.10 CrossCheck GPRS PowerThe CrossCheck GPRS operates on input voltages from 9–32 VDC. The low-noise amplifier integrated on the GPS antenna draws power from the CrossCheck GPRS through the antenna cable. The CrossCheck GPRS does not require any special power-up or down sequencing. The CrossCheck GPRS’s power circuitry is designed to protect the unit from random power fluctuations and conditions. Input circuits protect against transient voltage spikes found in most auto and truck environments. An external fuse protects against excessive current.For more information on the CrossCheck GPRS power requirements, see Appendix A.

2 Installation54 CrossCheck GPRS 1900 Installation ManualThe CrossCheck GPRS is protected against both input power over-voltage and reverse polarity. The DC ground line connects to the vehicle’s DC ground. The ignition-sense lead, if connected to a source of ignition-switched battery voltage, senses when the vehicle’s ignition is active. There are three connection options for connecting the power, ground, and ignition-sense wires. These options are described in the next three sections.2.10.1 Connections For Power Management The CrossCheck GPRS operates continuously only when the vehicle is running. When the ignition is off, the CrossCheck GPRS goes to sleep, drawing reduced power. For more information on current draw in different operation modes, see Appendix A. The default Power Management configuration for the CrossCheck GPRS is the following:• When the ignition is OFF, the unit goes to sleep state after 15 minutes.• If the EchoLDX is connected to the CrossCheck, the EchoLDX will turn off 1 minute after ignition OFF is detected.

2 Installation56 CrossCheck GPRS 1900 Installation Manual2.10.2 Continuous Power Connection No Power ManagementFor the Continuous Power connection (see Figure 2.29), the CrossCheck GPRS operates and draws power continuously, even when the vehicle is not running:• Idle mode (not transmitting) without the EchoLDX Message Terminal, 150 mA is typical @ 12 VDC• Idle mode (not transmitting) with the EchoLDX Message Terminal, 220 mA is typical @ 12 VDCICaution – When using the Continuous Power connection, the CrossCheck GPRS may drain a car battery in a vehicle that is not running in 1 to 3 weeks, depending on the battery size, quality, and remaining life span. In the Continuous Power connection, the CrossCheck GPRS 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 GPRS will automatically power off when the voltage drops below 9 VDC.

CHAPTER3Operation 3In this chapter:!Introduction!LED Indicators!GPS Receiver Operation
3 Operation60 CrossCheck GPRS 1900 Installation Manual3.1 IntroductionOnce you have installed and configured the CrossCheck GPRS, it is ready for operation. When power is applied, the CrossCheck GPRS operates automatically without user intervention, based on its firmware configuration.This chapter provides a basic overview of the CrossCheck GPRS’s operation, including:• LED Indicators• GPS Receiver• GPRS Transceiver
CrossCheck GPRS 1900 Installation Manual 61Operation 33.2 LED IndicatorsThe CrossCheck GPRS includes two LED indicators: GPS and GPRS. The firmware continuously monitors the GPS receiver and the CrossCheck GPRS operation. Figure 3.1 shows the CrossCheck GPRS LED indicators. Figure 3.1 CrossCheck GPRS LED Indicators 3.2.1 LED StatesThe GPS and GPRS LED have three states: On, Off, and Blink. When both LED indicators are off, the CrossCheck GPRS’s power is off. When one or more LED indicators are on or blinking, the power is on.GPS LED (Green)GPRS LED (Amber)
3 Operation62 CrossCheck GPRS 1900 Installation Manual3.2.2 LED Power-On SequenceWhen the CrossCheck GPRS’s ignition input and power inputs are activated:• The LEDs blink once.• Both turn off for approximately 5 seconds.The GPS LED is on for approximately 2 seconds, then blinks until the first position fix is computed. The GPRS LED blinks until the unit is registered with a GPRS network, at which point the GPRS LED turns on. 3.2.3 GPS and GPRS LED StatesTable 3.1 identifies the GPS LED states.Table 3.2 identifies the GPRS LED states.Table 3.1 GPS LED States (Green LED)GPS LED State MeaningOn Computing GPS position fixes.Blink Not computing GPS position fixes.Off No power is available, or the ignition is off.Table 3.2 GPRS LED States (Amber LED)GPRS LED State MeaningOn Data call in progress.Slow Blink No GPRS coverage is available; the CrossCheck GPRS is not registered with network.Off No power is available, or the ignition is off.
CrossCheck GPRS 1900 Installation Manual 63Operation 33.3 GPS Receiver OperationAt power-up, 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 requires less than 45 seconds—the green GPS LED blinks. • Once three or more satellites are acquired, the GPS receiver computes positions, course, and speed, and the GPS LED remains on. A blinking GPS LED 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 2 seconds.Note – If the CrossCheck GPRS unit does not have a valid last-known position, the unit will be forced to perform a cold start which normally requires less than 3 minutes. For example, this would happen the first time the unit is turned on, or if the unit has never been on long enough to obtain an Almanac. To obtain an Almanac, the unit must track GPS satellites for up to 30 minutes.
