1.2 CrossCheck GPRS 1900 Mobile Unit

The CrossCheck GPRS 1900 mobile unit is a mobile communications system module for Automatic Vehicle Location (AVL) and fleet asset management applications. It operates over the GPRS cellular network and allows simple, fast, and ef ficient transfer of information between a vehicle and the Telvisant Web-based gateway.

The CrossCheck GPRS unit integrates the following into a single, compact housing:

• A GPRS 900/1900 MHz cellular transceiver module

• A high-sensitivity, 8-channel GPS receiver

• A controller that features the proprietary firmware and integrated datalogging functions

The CrossCheck GPRS unit au tomatically reports arrival at or departure from an area that has been defined by a Site Dispatching message. The area may be either a new Job Site to be attended, or the Home Site (Base). CrossCheck GPRS unit also allows various asset utilization calculations.

Overview 1

1.2.1 Standard features

Note – The features and functions of this product are not identical to the features and functions of other products in the CrossCheck family, such as the CrossCheck AMPS, CrossCheck GSM, and CrossCheck XR.

The CrossCheck GPRS unit includes the following standard features:

• A sophisticated event handler for OTA configuration

• One serial port for messaging communication with the optional EchoLDX Message Terminal (PN 46722-00)

• discrete inputs, pulse counters, and outputs for vehicle peripheral support

CrossCheck GPRS 1900 Installation Manual 3

1 Overview

• Configurable Zone Logic Configuration packet: – Geo-fence area for Job Sites – Geo-fence area for Home Sites – Entry and exit speed limits for Site Dispatch purposes – Site dispatch time out – Minimum duration to detect entry/exit regions

• Storage of events and positions for up to one week while the CrossCheck GPRS is out of the coverage area

Note – The CrossCheck GPRS 1900 does not support the TAIP protocol, or the IQEventEngine firmware that is used by some CrossCheck products.

1.2.2 Optional system components

The EchoLDX™ Message Terminal is available as an optional system component. The Message T erminal is the messaging user interface in a fleet asset management system. It displays Text Messages, Job Sites, and Home Sites that the Telvisant Wireless Gateway sends to the CrossCheck GPRS unit.

1.2.3 Antenna requirements

To operate correctly, the CrossCheck GPRS unit must be connected to a GPRS antenna and to a GPS antenna. Because the type of antenna required depends on the application and installation location, the standard CrossCheck GPRS system does not include antennas. Trimble manufactures both bulkhead and magnetic mount GPRS and GPS antennas for use with a CrossCheck GPRS unit. These antennas must be ordered separately.

For information on the antennas that are available from Trimble, and their installation, see Chapter 2, Installation. For ordering information, see Appendix A, Specifications.

1.3 CrossCheck GPRS Applications

The 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 o f 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 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 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 acti vities.

• 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.

1.4 The Global Positioning System

The 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 Receiver

The CrossCheck GPRS unit includes an advanced GPS receiver, which provides the position, course, speed, and time information required for AVL and fleet management applications.

Overview 1

The integrated GPS receiver in the CrossCheck 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.

2.1 Introduction

This chapter provides instructions for installing the CrossCheck GPRS 1900 mobile unit in a vehicle.

Caution – The CrossCheck GPRS unit and its antennas and accessories should only be professionally installed by Trimble Authorized dealers.

Caution – To satisfy the FCC RF exposure requirements, a minimum separation distance of 20 cm must be maintained between the antenna and the operator. The maximum antenna gain, including any cable loss, must not exceed 3 dBi. If the antenna is installed close to another antenna, then the requirements of Section 1.1307 (b) (3) of the FCC rules (antenna co-location) must be satisfied.

Caution – The CrossCheck GPRS unit is designed for vehicle-mounted operation only. Do not use it for portable operation.

Note – If you install the CrossCheck GPRS unit before you install the EchoLDX terminal, make sur e that you allow adequate clearance between the two components. Leave enough room to connect the CrossCheck GPRS to the EchoLDX terminal, and make sure that the LED indicators on the CrossCheck GPRS are visible for troubleshooting.

2.5 Installing the CrossCheck GPRS Unit

To install the CrossCheck GPRS unit, you must carefully choose a mounting location, mount the unit, and then ground it.

Installation 2

2.5.1 Choosing a location for the CrossCheck GPRS unit

The CrossCheck GPRS unit can be installed in any orientation. Provided the installation location adheres to the environmental specifications, it can be installed in an enclosed compartment or in a location with limited accessibility. For example, the CrossCheck GPRS unit can be installed on the floor under a seat, or on a wall behind a seat.

Caution – Do not install the CrossCheck GPRS unit inside the engine compartment, in the wheel well, or on any exterior surface of the vehicle.

The CrossCheck GPRS unit ma y be mounted horizontally, vertically, or in any convenient orientation.

CrossCheck GPRS 1900 Installation Manual 15

2 Installation

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 (refrigerat ion un its)

• 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 there is excessive dust

Choose a location that:

• allows for con venient routing and connection o f 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 GPRS unit to a flat surface.

16 CrossCheck GPRS 1900 Installation Manual

2.5.2 Mounting the CrossCheck GPRS unit

The mounting flange has four holes for securing the unit to the flat surface. Use self-tapping screws or machine screws to secure the CrossCheck GPRS unit to the mounting surface.

Installation 2

Caution – 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 CrossChec k GPRS unit when the mounting screws are secured.

Figure 2.4 shows the mounting dimensions. The hole size leav es some allowance for holes that are drilled slightly off center from the specified dimensions.

CrossCheck GPRS 1900 Installation Manual 17

2 Installation

You must provide appropriate fasteners (either self-tapping screws or machine screws) for securing the CrossCheck 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 GPRS unit

For proper operation, the aluminum body of the CrossCheck 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 screws

If possible, ground the CrossCheck 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 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 tabs.

18 CrossCheck GPRS 1900 Installation Manual

Installation 2

Make sure that the screws are tight, and that they make contact both with the metal on the CrossCheck GPRS unit and with the vehicle chassis.

Note – If you use this method to connect the CrossChec k GPRS unit to the vehicle chassis, leave the chassis ground (pin 3 on the power and discrete I/O connector) on the CrossCheck GPRS unit unconnected.

Note – Make sure that the vehicle chassis is properly grounded in the vehicle.

Connection through the chassis ground wire

If the CrossCheck GPRS unit canno t 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 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 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 Antenna

To install the GPS antenna, you must carefully choose a mounting location, mount the antenna, and then route the antenna cable to the CrossCheck GPRS.

2.6.1 Choosing a location for the GPS antenna

Antenna 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

• is safe from damage during normal vehicle operation and maintenance

CrossCheck GPRS 1900 Installation Manual 19

2 Installation

• is not shielded from satellite signals by metal objects or other impenetrable materials

GPS 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.

20 CrossCheck GPRS 1900 Installation Manual

Caution – Do not mount the GPS antenna under a metallized glass

windshield, such as those used in some vehicles f or window de-f ogging 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 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.

• Avoid areas of high vibration, such as engine hoods.

Installation 2

• 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 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.

2 Installation

2.6.3 Routing the GPS antenna cable

The magnetic GPS antenna has an integrated antenna cable, and the miniature bulkhead GPS antennas have separate cables.

If you are using a miniature bulkhead GPS antenna, attach the antenna cable to the connector on the base of the antenna before you route the cable. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck GPRS unit, while observing the following guidelines:

• Make sure that there is at least 5.1 cm (2") of clearance between the CrossCheck GPRS antenna connector and the nearest obstacle.

• Make sure that the minimum ra dius of all cabl e b ends is 1.3 cm (1"), especially the bend at the SMA strain relief to the antenna connector.

• 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 coaxial cable is not routed through areas where vehicle movement can abrade (wear away) 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.

2.7.3 Routing the cellular antenna cable

The next step in the installation process is routing and connecting the antenna cable to the CrossCheck GPRS unit. When routing the cable, start at the antenna and choose the most direct path to the CrossCheck 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 cable

The 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 GPRS. Tighten the connector firmly to prevent loosening caused by normal vehicle vibration.

Connecting the bulkhead or glass mount cellular cable

The 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 GPRS unit. For instructions on how to install the TNC-p connector, see page 41.

46 CrossCheck GPRS 1900 Installation Manual

2.8 CrossCheck GPRS Power

The CrossCheck 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 GPRS unit through the antenna cable. The CrossCheck GPRS unit does not require any special powerup or power-down sequencing.

The CrossCheck 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 GPRS unit power requirements, see Appendix A, Specifications.

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 Power

These options are described in the following sections.

2.8.1 Power Management option

When the CrossCheck 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 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 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.

2. Connect the ignition-sense line to ignition-switched battery power, so that this line is active when the ignition is on.

50 CrossCheck GPRS 1900 Installation Manual

2.8.2 Continuous Power option

When the CrossCheck 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.

Installation 2

Caution – When connected to the vehicle’s battery using the Continuous Power option, the CrossCheck GPRS unit may drain the battery if the vehicle is not running for se v eral 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 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 GPRS unit will automatically power off when the voltage drops below 9 V DC.

To logic

For input specifications, see Table A.16 on page 76. Each input floats to a logic-high state (inactive) when left open.

Grounding an input causes a logic-low state (active). The CrossCheck 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 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 av oid 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.

3 Operation

3.1 Introduction

Once you have installed and configured the CrossCheck GPRS unit, it is ready for operation. When power is applied, the CrossCheck GPRS unit operates automatically without user intervention.

This chapter provides a basic overview of how the CrossCheck GPRS unit operates.

3.2 LED Indicators

The CrossCheck 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 GPRS unit firmware monitors continuously.

GPRS LED (Amber)

GPS LED (Green)

Figure 3.1 LED indicators

The GPS and GPRS LED indicators have three states: on, off, and flash. When both indicators are off, the CrossCheck GPRS unit’s power is off. When one or both LED indicators are on or flashing, the power is on.

by a PIN.

3.2.2 LED power-on sequence

When the CrossCheck GPRS unit’s ignition and power inputs are activated:

• 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.

CrossCheck GPRS 1900 Installation Manual 61

3 Operation

• 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 Operation

When the CrossCheck 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 GPRS un it 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.

62 CrossCheck GPRS 1900 Installation Manual

3.4 Registration

When the CrossCheck 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 GPRS unit until it is turned off.

When the CrossCheck GPRS unit has successfully registered with the network, the amber GPRS LED stays on. The CrossCheck 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 GPRS unit is connected to the Telvisant Wireless Gateway.

Operation 3

When the vehicle is stopped or parked and the ignition is turned off, the CrossCheck 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 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.
