1.3 CrossCheck CDPD 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 CDPD
receiver. You can use the receiver as a standalone unit, or you can
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
to exchange messages or generate event reports.
The CrossCheck CDPD 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 activities
•Improve customer service 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

1.4 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 land-
based 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 CrossCheck CDPD includes an advanced GPS receiver, which
provides the position, course, speed and time information required for
AVL and fleet management applications. A brief overview of the GPS
receiver’s architecture and operation is provided in the next paragraph.
The CrossCheck CDPD’s GPS receiver features an eight-channel
digital signal processor (DSP) 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.

2.6 Mounting the CrossCheck CDPD
The CrossCheck CDPD can be installed inside any type of vehicle and
in any orientation. It can be installed in an enclosed compartment 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
convenient routing and connection of the antenna and interface 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 horizontally, vertically,
or in any convenient orientation. During normal system
operation, you do not need to see the CrossCheck CDPD LED
indicators. However, the ability to see the LED indicators is a
definite advantage when troubleshooting the unit.
CrossCheck CDPD Mobile Unit Manual 17
Installation 2
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 – Over-stressing the plastic mounting surface when
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 operation, the aluminum chassis of the CrossCheck CDPD
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 (preferred)
•Connection through the chassis ground wire
CrossCheck CDPD Mobile Unit Manual 19
Installation 2
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 they 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
If the CrossCheck CDPD cannot be mounted directly on a metal
surface that 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 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.

20 CrossCheck CDPD Mobile Unit Manual
2.7 Choosing the GPS Antenna Mounting Location
Antenna location is critical for optimum GPS performance. When
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 relatively dry. GPS satellite signals do not penetrate metal 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 coverage, since the metal components of the vehicle shield the
antenna from portions of the sky.
,Caution – Do not mount the GPS antenna under a metallized glass
windshield, such as those used in some vehicles for window de-
fogging 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 or may not be compatible with the
CrossCheck CDPD, including combined GPS/CDPD cellular
antenna solutions which have not yet been tested and certified
by Trimble.
CrossCheck CDPD Mobile Unit Manual 21
Installation 2
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.

2.8 Routing the GPS Antenna Cable
The Magnetic GPS Antenna has an integral antenna cable, and the
Miniature Bulkhead GPS Antennas have a separate 5-m
(approximately 16 ft.) cable.
If you are using one of the Miniature Bulkhead GPS Antennas, attach
the antenna cable to the connector on the base of the antenna prior to
routing the cable. When routing the cable, start at the antenna and
choose the most direct path to the CrossCheck CDPD while observing
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 obstacle.
•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 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 coax cable is not routed through areas where
vehicle movement can abrade the cable surface.
•Never coil the excess antenna cable, particularly the Magnetic
GPS antenna cable. A coiled cable can act as an antenna and
may receive interference.
•Protect cables from exposure to corrosive fluids.
Once the cable is routed and secured, attach the cable to the
CrossCheck CDPD GPS (SMA) connector.

products. There are many other cellular antennas available on the
market which may or may not be compatible with the
CrossCheck CDPD, including combined GPS/Cellular antenna
solutions which have not yet been tested and certified by Trimble.
Although not as critical as GPS antenna placement, cellular antenna
placement is also important. Mount the cellular whip antenna in a
vertical orientation in a location where it is safe from damage during
normal vehicle operation and maintenance. Automated vehicle washes
may damage misplaced cellular antennas.
2 Installation
32 CrossCheck CDPD Mobile Unit Manual
Maintain a separation of at least 46 cm (or approximately 18 in.)
between the cellular (or other) and GPS antennas (as illustrated in
Figure 2.12).
Figure 2.12 Distance Between Antenna Locations
In general, the greater the separation, the less chance of interference.
For permanent antenna 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.
Cellular phone dealers and installers are experts on cellular antenna
placement. For some installations, the installer may substitute a glass-
mount antenna for the antenna supplied by Trimble. Other antennas
are acceptable as long as they conform to the requirements listed in
Appendix A.
Trimble offers two cellular antenna options for the

2.9.3 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 cable, which is terminated 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 CrossCheck 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 door. Provide an adequate service
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 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.
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
its route.

2.9.6 Inputs (IP0 to IP3)
The CrossCheck CDPD supports four discrete inputs. The circuit
diagram is shown in Figure 2.19.
Figure 2.19 Input Circuit Diagram
Each input floats to a logic-high state (inactive) when left open.
Grounding an input causes a logic-low state (active). The
CrossCheck CDPD can be configured to detect either logic-high or
logic-low states at the inputs whenever the unit is powered on.
Note – When the CrossCheck CDPD is powered off or in Power
Management mode, it can only detect a logic-low (grounded) input.
The discrete inputs are compatible with properly connected relays and
switches or with standard 3.3 VDC 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.
Input Logic High: Open circuit or Vin > 2.4 VDC
Input Logic Low: Vin < 0.6 VDC
The inputs must remain in either state for at least
200 milliseconds before the CrossCheck CDPD
detects the input.

The CrossCheck CDPD is protected against both input power over-
voltage 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.

2.10.2 Continuous Power Connection (No Power Management)
For the Continuous Power configuration (see Figure 2.25), the
CrossCheck CDPD operates and draws power continuously, even
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 – With the Continuous Power Configuration, the
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. Observe
extreme care when using this connection option. The
CrossCheck CDPD will automatically power off when the voltage
drops below 9 VDC.

Installing the Echo
LDX
Kit
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
EchoLDX Message Terminal for CrossCheck CDPS and CrossCheck
GPRS Installation and User’s Manual, Trimble Part Number 46667-
00-ENG.
2.11.2 Preparing for Installation
Inventory
Prior to installation, confirm that you have received the required
EchoLDX components:
•EchoLDX Message Terminal
•Power/Data cable
•EchoLDX mounting pedestal kit (6") and mounting hardware
•EchoLDX Quick Reference Guide
CrossCheck CDPD Mobile Unit Manual 51
Installation 2
2.11.3 Choosing a Location
Choose a location 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.
2.11.4 Mounting the Pedestal and Installing the Echo
LDX
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.
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 that there is clearance behind the mounting surface for
the mounting screws. Choose the appropriate screws to install
the pedestal to the mounting surface—either sheet metal screws
or machine screws with lock nuts.
3. Remove the MDT from the top of the pedestal.
2 Installation
52 CrossCheck CDPD Mobile Unit Manual
4. Place the pedestal base on the mounting surface and secure it
with the appropriate screws.
Figure 2.26 Echo
LDX
Attached to Mounting Assembly
5. Affix the MDT to the mounting pedestal. Position the MDT and
tighten all locking nuts.
2.11.5 Routing the Power/Data Cable
The next step in the installation process is to route the Power/Data
cable from the EchoLDX to the CrossCheck. When routing the cable,
avoid the following hazards:
•Sharp bends or kinks in the cable
•Hot surfaces (exhaust manifolds or stacks)
•Rotating or reciprocating equipment
CrossCheck CDPD Mobile Unit Manual 53
Installation 2
•Sharp or abrasive surfaces
•Door and window jambs
•Corrosive fluids or gases
Follow these installation guidelines:
•Choose the most direct path to the destination.
•Leave enough excess cable for a service loop, to allow for
removal of the EchoLDX and the CrossCheck.
•Secure the cable to the pedestal with a cable tie.
Power and Interface Connections
The 2.90 m Power/Data cable provided with the EchoLDX includes a
RJ-45 connector at one end and a serial connection and a DB9M at the
other (as shown in Figure 2.27).
Figure 2.27 Echo
LDX
Power/Data Cable
2 Installation
54 CrossCheck CDPD Mobile Unit Manual
The cable connects to the CrossCheck through the DB9F connector
labeled MDT. Power is supplied to the EchoLDX through the same
data cable.
Note – When the cable connection is complete, secure the cable using
a cable tie.
Table 3.1 describes the pin locations for the EchoLDX connector and
the Power/Data cable, as viewed from the front of the connector.

56 CrossCheck CDPD Mobile Unit Manual
3.1 Introduction
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
3.2 LED Indicators
The CrossCheck CDPD includes two LED indicators: GPS and GSM.
The firmware:
•Continuously monitors the GPS receiver and the
CrossCheck CDPD phone operation
•Controls the two LED indicators
CrossCheck CDPD Mobile Unit Manual 57
Operation 3
Figure 3.1 shows the CrossCheck CDPD LED indicators.
Figure 3.1 CrossCheck CDPD LED Indicators
3.2.1 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.
3.2.2 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.
Warning: All persons must
be at least 20 cm from
antenna when transmitter
operating to meet FCC RF
exposure requirements.
GPS LED (Green)
CDPD LED (Amber)
3 Operation
58 CrossCheck CDPD Mobile Unit Manual
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.
Table 3.2 identifies the GSM LED states.
Table 3.1 GPS LED States (Green LED)
GPS LED State Meaning

Blink Not computing GPS position fixes.
Off No power is available, or CrossCheck CDPD is in Sleep mode.
Table 3.2 GSM LED States (Amber LED - when GPS green LED is on or flashing)
CDPD LED State Meaning
On Data call in progress.
Slow Blink No CDPD coverage is available; the CrossCheck CDPD is not registered
with network.
Off CDPD coverage is available; no call in progress.
CrossCheck CDPD Mobile Unit Manual 59
Operation 3
3.3 GPS Receiver Operation
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.
