1.1 Introduction
This manual describes the CrossCheck GPRS 1900 mobile unit. The
CrossCheck GPRS unit is designed to be used with Trimble’s
Telvisant Wireless Gateway (TWG) for fleet asset management and
Automatic Vehicle Location (AVL).
The CrossCheck GPRS unit runs the firmware necessary to
communicate with the TWG. The CrossCheck GPRS firmware:
• automatically reports location-based information such as
• sends alerts when the vehicle stops or exceeds a specified speed
• provides information such as vehicle run time and mileage
• provides information such as sensor feedback (if installed)
The TWG can program the CrossCheck GPRS unit over the air (OTA).
You can request OTA programming to change configuration
parameters or the entire code set.

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.

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.
