Introduction
1.1
This manual describes the CrossCheck CDPD Mobile Unit which is
designed to be used with Trimble’s Wireless Location Gateway
(WLG) for Fleet Asset Management and Automatic Vehicle Location
(AVL) purposes.
The CrossCheck CDPD runs the firmware necessary to communicate
with the Wire Loca tion Gateway and automatically reports locationbased information such as pos ition, s peed, an d direct ion, and when the
vehicle stops or excee ds a specif ied speed . It also pro vides inf ormation
such as vehi cle run t ime an d mile age and is pr ogrammabl e o v er t he a ir
(OTA) by the gateway. Configuration parameters, or the entire code
set, can be changed.

The CrossCheck CDPD Mobile Unit
1.2
The CrossCheck CDPD Mobile Unit is ho used in a sing le, 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 CDPD cellular network and allows
simple, fast, and efficient transfer of information between a vehicle
and Trimble’s Web-based gateway.
The CrossC heck CDPD Mobile Unit integrates the following into a
single package:
• A CDPD 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

1.2.1
Note – The CrossCheck CDPD does not support the IQEventEngine
firmwar e used by other CrossCheck products and does not support the
TAIP protocol.
CrossCheck CDPD Standard Features
The CrossCheck CDPD automatically reports arrival or departure
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 CDPD also allows
various asset utilization calculations.

Overview
1
The CrossCheck CDPD includes the following:
• Eight-channel GPS receiver
• A sophisticated event handler that allows the
CrossCheck CDPD to be configured over the air (OTA) to
respond to a wide variety of dispatch and fleet asset
management operations
• One serial port for Mobile Data Terminal (MDT) operation
• 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 CDPD to
store events and positions for up to 1 week while out of the
network. Each item is checked for the 1-week expiration and
discarded if appropriate.
1.2.2
CrossCheck CDPD 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 CDPD to receive
and display text messages, Job Sites, and Home Sites from the
Wirele ss Locat ion Gateway.

Antenna Requirements
CDPD and GPS antennas are required for operation. Bulkhead and
magnetic mount GPS antennas are available from Trimble. Chapter 2
describes the antennas and antenna installation.
The standard CrossCheck CDPD configuration does not include a
GPS or CDPD antenna because the type of antenna required depends
on the application. Antennas must be ordered separately. For more
information, see Appendix A, Specifications.

CrossCheck CDPD Applications
1.3
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 CDPD
receiver. You can use the receiver as a standalone unit, or you can
interface it with e xterna l accessories and sensors to make i t 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 CDPD and applications can do the following:
• Automate vehicle status changes for dispatching applications
Overview

• 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 tomer se rvice 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

The Global Positioning System
1.4
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.
GPS Receiver
1.5
The CrossCheck CDPD includes an advanced GPS receiver, which
provides the pos it io n, course, speed and time information requ ir ed for
AVL and fle et mana gement a ppl ica ti ons . A br ie f overview of the GPS
receiver’s archite ct ure and operation is provided in the ne x t paragraph.
The CrossCheck CDPD’s GPS receiver features an eight-channel
digital signal processor (DSP) which operates at the GPS L1
frequency (1 575.42 MHz) and processes t he Coarse/Acq uisition (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.
