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

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.

Mounting the CrossCheck CDPD

2.6

The CrossCheck CDPD can be installed inside any type of v ehicle and
in any orientat ion. It can be in stalled i n an enclosed co mpartment or in
a location with limited accessibility, as long as the environmental
specifications are maintained to ensure reliable operation. For
example, the CrossCheck CDPD can be installed on the floor under a
seat, or on a wall behind a seat.

Note – The CrossCheck CDPD cannot be installed inside the engine
compartment, wheel well, chassis, or on any exterior surface of the
vehicle.

Choose a location for the CrossCheck CDPD that allows for
conv enie nt routing and connectio n of the antenn a and inte rface 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 CDPD is not waterproof.)

To mount the CrossCheck CDPD:

1. Choose the mounting location.
The CrossCheck CDPD can be mounted horiz ontally, vertical ly ,

or in any convenient orientation. During normal system
operation, you do not need to see the CrossCheck CDPD LED
indicator s. However, the ability to see the LED indicators is a
definite advantage when troubleshooting the unit.

CrossCheck CDPD Mobile Unit Manual

16

Installation

The integral mounting flange is designed to secure the
CrossCheck CDPD 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.

,

Caution –

tightening the mounting screws can cause the plastic to crack. Use
washers sized small enough that they do not tighten down on the
plastic cover of the CrossCheck CDPD when the mounting screws are
secured. Tightening screws without using washers can lead to
compressing, cracking, or deforming the mounting surface.

The installer must provide an appropriate selection of fasteners to
secure the CrossCheck CDPD 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 CDPD to the Vehicle Chassis

For proper operatio n, the alumi num cha ssi s of the Cr oss Check CDPD
must be connected electr ic ally ( grounde d) to t he chass is of t he v ehi cle
on which it installed. This can be accomplished in two ways:

• Direct connection through metal screws (preferred)

• Connection through the chassis ground wire

CrossCheck CDPD Mobile Unit Manual

18

Installation

Direct Connection through Mounting Screws

To mount the CrossCheck CDPD 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 CDPD 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 the y make contact both
with the metal on the CrossCheck CDPD 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 CDPD should
be left unconnected.

Connection through the Chassis Ground Wire

2

If the CrossCheck CDPD cannot be mounted directly on a metal
surface that is atta ched t o the v eh icle, then use t he chass is gr ound wi re
(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 18 AWG to connect the
CrossCheck CDPD 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 CDPD.

Choosing the GPS Ant enna Mounting Location

2.7

Antenna location is crit ical for optim um GPS perfo rmance. Wh en
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 re lati v ely dr y. GPS satellite sig nals do not penet rate meta l 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 co verage, s ince the meta l components of the vehic le shield the
antenna from portions of the sky.

Caution –

windshield, such as those used in some vehicles for window de­fogging 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 o r may not be co mpatible with the
CrossCheck CDPD, including combined GPS/C DPD cellular
antenna solutions which have not yet been tested and certified
by Trimble.

Do not mount the GPS antenna under a metallized glass

Installation

Additional 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.

the following guidelines:

• Make sure that at least 5.1 cm (2 in.) of clearance exists
between the CrossCheck CDPD's antenna connector and the
nearest ob stacle.

• Make all cable bends, especially the bend at the SMA strain
relief to the antenna connector, with at least 1.3 cm (0.5 in.)
bend radius.

• Provide an adequ ate servi ce loop when routi ng the cabl e around
vehicle hinges to ensure that the cable is not pinched when a
hinged door opens or closes.

• Make sure that the coa x cabl e is not rou ted through areas whe re
vehicle movement can abrade the cable surface.

• Never coil the excess antenna cable, particularly the Magnetic

Routing the Cellular Antenna Cable

The Magnetic Cellular antenna has an integral antenna cable with a
TNC-M connector. The Bulkhead Cellular antenna has a 5-m (16 ft.)
integral antenna cab le, which is termi nated within the FME connector.
After routing the Bulkhead Cellular cable, the cable must be fitted
with a TNC (plug) connector, before attaching the cable to the
CrossCheck CDPD. Instructions for installing the TNC connector are
included with the antenna kit.

The next step in the installation process is routing and connecting the
antenna cable to the Cro ssCheck CDPD. When routing the cable, start
at the antenna and choose the most direct path to the
CrossCheck CDPD 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 d oor . Pro vide an adeq uate servic e
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 ab rade the cab le 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 Magnetic Cellular antenna cable is exposed to the
environment. Since the wind could cause the cable to whip
around, tie wraps should be used to secure the cable along

CrossCheck CDPD Power

2.10

The CrossCheck CDPD operates on input voltages from 9–32 VDC.
The low-noise amplifier integrated on the GPS antenna draws power
from the CrossCheck CDPD through the antenna cable. The
CrossCheck CDPD does not require any special power-up or down
sequencing.

The CrossCheck CDPD’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 p rotects against excessive current.

For more information on th e CrossCheck CDPD power requirements,
see Appendix A.

The CrossCheck CDPD is protected against both input power over­voltage and reverse polarity. The primary power cable has a built-in
fuse. 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 CDPD operates continuously only when the vehicle
is running. When the ignition is off, the CrossCheck CDPD 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 CDPD is the following:

• When the ignition is OFF, the unit goes to sleep state after
3 minutes.

• If the EchoLDX is connected to the CrossCheck, the EchoLDX
will turn off 1 minute after ignition OFF is detected.

when the vehicle is not running:

• Idle mode (not transmitting) without the EchoLDX Message
Terminal, 130 mA is typical @ 12 VDC

• Idle mode (not transmitting) with the EchoLDX Message
Terminal, 200 mA is typical @ 12 VDC

Caution –

CrossCheck CDPD may drain a car battery in 1 to 3 weeks,
depending on the battery quality and remaining life span, and whether
or not the vehicle is operating during the entire time.

Installing the Echo

2.11

The EchoLDX Message Terminal can be installed in almost any type
of vehicle. There are four steps in this procedure:

1. Assemble the mounting pedestal.

2. Mount the EchoLDX.

3. Route the Power/Data cable.

4. Connect the Power/Data cable to the CrossCheck CDPD.

This section provides detailed installation instructions.

2.11.1

Configuration Parameters

In addition to the physical installation of the unit, configuration
parameters can be set in each unit. Trimble recommends that if a
configuration other than the factory setting is used, every unit in the
fleet be given the same settings so that operation is consistent from
vehicle to vehicle. EchoLDX configuration is discussed in the

Choosing a Location

Choose a loc ation for the EchoLDX where the display is easy to view
and the keypad is readily accessible. When selecting a location, avoid
exposure to extreme environmental conditions, including:

• Excessive heat or cold

• High vibration

• Corrosive fluids and gases

• Wet or damp locations

Avoiding these conditions will improve the EchoLDX's performance
and will ensure long-term reliability.

All standard external connections to the EchoLDX are made through
the connector (marked as 2) on the bottom of the unit.

Mounting the Pedestal and Installing the Echo

The EchoLDX can be attached to any flat surface using the mounting
assembly. When positioning the assembly on the mounting surface,
allow sufficient clearance beneath the EchoLDX for the Power/Data
cable and on the right side of the unit for the maintenance and
upgrade cable.

LDX

To mount the pedestal:

1. In the vehicle, select a mounting surface for the pedestal and
temporarily place the MDT at the top on the pedestal. Ensure
that the MDT is accessible by all possible operators.

2. Verify tha t there is clear ance behind the mounting surface for
the mounting screws. Choose the appropriate screws to install
the pedestal to the mount ing sur fa ce—eith er s heet met al s cre ws
or machine screws with lock nuts.

Introduction

3.1

Once you have installed and configured the CrossCheck CDPD, it is
ready for operation. When power is applied, the CrossCheck CDPD
operates automatically without user intervention, based on its
firmware configuration.

This chapter provides a basic overview of the CrossCheck CDPD ’s
operation, including:

• LED Indicators

• GPS Receiver

• CDPD Transceiver

LED Indicators

3.2

The CrossCheck CDPD includes two LED indicators: GPS an d GSM .
The firmware:

• Continuously monitors the GPS receiver and the
CrossCheck CDPD phone operation

• Controls the two LED indicators

CrossCheck CDPD Mobile Unit Manual

3.2.2

LED States

The GPS and CDPD LED have three states: On, Off, and Blink.
When both LED indicators are off, the CrossCheck CDPD’s power is

off. When one or more LED indicators are on or blinking, the power
is on.

LED Power-On Sequence

When the CrossCheck CDPD’s ignition input and power inputs are
activated:

• The LEDs blink once.

• Both turn off for approximately 5 seconds.

• Both remain on for approximately 2 seconds.

CrossCheck CDPD Mobile Unit Manual

57

Operation

The GPS LED is on for approximately 2 seconds, then blinks until the
first position fix is computed. During this period, the CDPD LED
blinks until the unit is established in a CDPD area, at which point the
CDPD LED turns off. When a call is active, the CDPD LED stays on
for the duration of the call.

3.2.3

GPS and CDPD LED States

Table 3.1 identifies the GPS LED states.

GPS Receiver Operation

3.3

At power-up, the GPS receiver initializes with the last-known position.
Using this information, the GPS receiver acquires satellite signals.

• During the satellite acquisition process—which normally
requires less than 2 minutes—the green GPS LED blinks.

• Once three or more satellites are acquired, the GPS receiver
computes positions, course, speed and time fixes, 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.
