Introduction

This manual describes the CrossCheck GPRS 1900 Mobile Unit
which is designed to be used with Trimble’s Telvisant™ Wireless
Gateway (TWG) for Fleet Asset Management and A utomatic Vehicle
Location (AVL) purposes.

The CrossCheck GPRS runs the firmware necessary to communicate
with the TWG and automatically reports location-based information
such as position, speed, and direction, and when the vehicle stops or
exceeds a spec ified speed. It al so pro vides i nformat ion suc h as v ehicl e
run time and mileage and is programmable over the air (OTA) by the
gateway. Configuration parameters, or the entire code set, can be
changed.

1.2

The CrossCheck GPRS 1900 Mobile Unit

The CrossCheck GPRS 1900 Mobile Unit is housed in a single,
compact enclosure that simplifies installation and provides greater
reliability.

This package 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 efficient transfer of information between a vehicle
and Trimble’s Web-based gateway.

The CrossCheck GPRS 1900 Mobile Unit in tegr ates the fo llowi ng into
a single package:

• A GPRS 900/1900 MHz cellular transceiver module

• A high-sensitivity, 8-channel GPS receiver

• The controller, featuring the proprietary firmware and
integrated datalogging functions

The product’s features and functions are not identical to other
products in the CrossCheck family, such as the CrossCheck AMPS
CrossCheck GSM, and CrossCheck XR.

Overview 1

1.2.1

Note – The CrossCheck GPRS does not support the IQEventEngine™
firmware used by other CrossChec k products and does not support the
TAIP protocol.

CrossCheck GPRS Standard Features

The CrossCheck GPRS automatically reports arri val or departur e from
an area that has been previously defined via a Site Dispatching
message, that can include either a new Job Site to be attended or a
return to the Base or Home Site. CrossCheck GPRS also allows
various asset utilization calculations.

CrossChec k GP RS 19 00 I ns tallation Manual 3

1 Overview

The CrossCheck GPRS includes the following:

• Eight-channel GPS receiver

• A sophisticated e vent han dler that allo ws the Cros sCheck GPRS
to be confi gur ed over the air (OTA) to respond to a wide v a ri ety
of dispatch and fleet asset management operations

• One serial port for Mes saging oper ation when usin g the T rimble
EchoLDX Message Terminal (P/N 46722-00)

• Extensive discrete I/O inputs, pulse counters, and outputs for
vehicle peripheral support

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

• Support for datalogging that allows the CrossCheck GPRS to
store events and positions for up to one week while out of the
network. Each item is ch ecked for the one-week expiration and
discarded if appropriate.

1.2.2

CrossCheck GPRS Options

The following option is available: EchoLDX™ Message Terminal
(MDT), the messaging user-interface component of a fleet asset­management system.

The EchoLDX terminal connects to the CrossCheck GPRS to receive
and display text messages, Job Sites, and Home Sites from the
Telvisant Wireless Gateway.

Antenna Requirements

GPRS and GPS antennas are required for operation. Bulkhead and
magnetic mount GPS and GPRS antennas are available from Trimble.
Chapter 2 describes the antennas and antenna installation.

The standard CrossCh eck GPRS configuration does not i nclude a GPS
or GPRS antenna because the ty pe of ante nna requi red depe nds on the
application. Antennas must be ordered separately. For more
information, see Appendix A, Specifications.

CrossCheck GPRS Applications

The 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 externa l accessorie s 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

Overview 1

• Determine time spent and distance traveled on jobs for
accounts-payable systems

• Improve efficiency by detecting unauthorized vehicle stops or
off-route activities

• Improve cus to me r s er vic e 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 Overview

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.

GPS is the most accurate technology available for navigation. As a
satellite-based system, GPS is immune from the limitations of land­based 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 Receiver

The Cross Check GPRS includes an advanced GPS receiver, which
provides the po sit i on, course, speed and time infor m at ion requ ired for
AVL and fleet management applications. A brief overview of the GPS
receiver’s architecture a nd ope rat ion 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) a nd 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.

Installing the CrossCheck GPRS Mobile Unit

Warning – 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 m ust 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.

The CrossCheck GPRS 1900 Mobile Unit can be installed before or
after configuring its firmware. For example, you might want to
configure all of the units for a fleet of vehicles prior to installation.

Note – If you plan to install the CrossCheck GPRS receiver before
installing the EchoLDX Message Terminal, be sure to leave adequate
clearance to the Mobile Data Terminal port and other connectors.
Adequate cleara nce must e xi st to co nnect th e Messa g e Terminal to the
unit, and you must be able to read the LED indicators if
troubleshooting is required.

Warning – The SIM card provided with the CrossCheck GPRS must not
be removed. It has been locked to work only with this device and cannot
be used with any other GPRS phone.

GPRS Antenna

The CrossCheck GPRS 1900 uses a TNC receptacl e connector for the
GPRS antenna. For more information, see Appendix A.

Inspecting and Unpacking the Shipment

The CrossCheck GPRS may be shipped in one or more cartons,
depending on the number of units and the options ordered with the
shipment. Before opening the shipping containers, inspect the cartons
for punctures or damage and immediately report any damage to the
shipping carrier. Then open the shipping cartons individually and
check their contents against the packing slip.
