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 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 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 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

Overview
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 CrossCheck GPRS 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 GPRS’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.

should only be professionally installed by Trimble Authorized dealers.
Warning – For 1900 MHz PCS:
A minimum separation distance of 20 cm must 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.
2.2
Installing the CrossCheck GPRS Mobile Unit
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 clearance must exist to connect the Message Terminal to the
unit, and you must be able to read the LED indicators if
troubleshooting is required.

Installation
Mounting the CrossCheck GPRS
The CrossCheck GPRS can be installed inside almost 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 GPRS can be installed on the
floor under a seat, or on a wall behind a seat.
Note – The CrossCheck GPRS cannot be installed inside the engine
compartment, wheel well, chassis, or on any exterior surface of the
vehicle.
Choose a location for the CrossCheck GPRS 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 GPRS is not waterproof.)
•
Areas where excessive dust will be present
To mount the CrossCheck GPRS:
1.
Choose the mounting location.
The CrossCheck GPRS can be mounted horizontally, vertically,
or in any convenient orientation. During normal system
operation, you do not need to see the CrossCheck GPRS LED
indicators. However, the ability to see the LED indicators is a
definite advantage when troubleshooting the unit.
16
CrossCheck GPRS 1900 Installation Manual
Installation
The integral mounting flange is designed to secure the
CrossCheck GPRS 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 crack the plastic. Use washers
sized small enough that they do not tighten down on the plastic cover
of the CrossCheck GPRS when the mounting screws are secured.
Tightening screws without using washers can lead to compressing,
cracking, or deforming the mounting surface.

secure the CrossCheck GPRS to the mounting surface.
•
•
2.6.1
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.
Connecting CrossCheck GPRS to the Vehicle Chassis
For proper operation, the aluminum chassis of the CrossCheck GPRS
must be connected electrically (grounded) to the chassis of the vehicle
on which it installed. This can be accomplished in two ways:
18
•
Direct connection through metal screws (preferred)
•
Connection through the chassis ground wire
CrossCheck GPRS 1900 Installation Manual
Installation
Direct Connection through Mounting Screws
To mount the CrossCheck GPRS 1900 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 GPRS 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 GPRS 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 GPRS should be
left unconnected.
Connection through the Chassis Ground Wire
If the CrossCheck GPRS 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 20 AWG to connect the
CrossCheck GPRS 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 GPRS.

Installation
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.
For optimum performance, the GPS antenna should be mounted on a
metal groundplane of at least 7.5 cm square (3 in. x 3 in.).
Caution – Do not mount the GPS antenna under a metallized glass
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 or may not be compatible with the
CrossCheck GPRS, including combined GPS/GSM cellular antenna
solutions which have not been tested or certified by Trimble.
20
CrossCheck GPRS 1900 Installation Manual
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 bulkheadmount 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.

Routing the GPS Antenna Cable
The Magnetic GPS Antenna has an integral antenna cable, and the
Miniature Bulkhead GPS Antennas have separate cables.
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 GPRS while observing
the following guidelines:
•
Make sure that at least 5.1 cm (2 in.) of clearance exists
between the CrossCheck GPRS'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 (1 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
cause interference problems.
•
Protect cables from exposure to corrosive fluids.
Once the cable is routed and secured, attach the cable to the
CrossCheck GPRS GPS (SMA) connector.

Corners of the rear window or a side window are often best.
Warning – Do not mount the antenna where it can obstruct the driver’s
visibility.
Caution – Avoid installing the antenna:
- on curved glass.
- on glass with metallic content (that is, passivated glass:
“solar coat” or “solar cool”). Check with auto manufacturer.
- on any dark tinted area, or an area where aftermarket
tinting film has been applied.
- over in-glass AM/FM dipole antenna.
2.
Clean both inside and outside mounting areas with enclosed
alcohol pad. Wipe off excess alcohol (do not allow alcohol to
dry on the glass). If there is an obvious film on the window, use
a mildly abrasive detergent to clean.
Note – To install the antenna over defroster wires, the wires must be
placed at least one inch or more apart. Center the antenna over one

Installation
Routing the Cellular Antenna Cable
The Magnetic Cellular antenna has a 3.65 m (12 ft.) integral antenna
cable with a TNC-plug (TNC-p) connector. The Bulkhead Cellular
antenna has a 5.1 m (17 ft.) integral cable and the Glass Mount
Cellular antenna has a 4.5 m (15 ft.) integral cable; both cables are
terminated without a connector.
After routing the Bulkhead Cellular or Glass Cellular cable, it must be
fitted with a TNC-p connector before attaching the cable to the
CrossCheck GPRS. Instructions for installing the TNC-p connector
are included with the antenna kit.
The next step in the installation process is routing and connecting the
antenna cable to the CrossCheck GPRS. When routing the cable, start
at the antenna and choose the most direct path to the
CrossCheck GPRS while avoiding the following hazards:
44
•
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.

Connecting the Magnetic Cellular Antenna Cable
After routing the Magnetic Cellular Antenna cable, connect the cable
to the TNC connector on the front panel of the CrossCheck GPRS.
Tighten the connector firmly to prevent loosening caused by normal
vehicle vibration.
2.9.6
Connecting the Permanent or Glass-Mount Cellular Cable
Once the cable routing is complete and the cable is secured attach the
TNC connector on the antenna cable. Then attach the cable to the TNC
connector on the front panel of the CrossCheck GPRS.

Each input floats to a logic-high state (inactive) when left open.
Grounding an input causes a logic-low state (active). The
CrossCheck GPRS 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 GPRS 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.

Outputs (XP0 to XP2)
The CrossCheck GPRS features three discrete outputs (XP0–XP2) for
driving external devices such as relays, alarms, and so on.
•
When inactive (use state), the discrete outputs are tied to vehicle
battery voltage (nominally 12 VDC) through a 15 kOhm
resistor.
•
When active, the outputs are shorted to ground through a
bipolar junction transistor. In the active (low) state, the outputs
can sink up to 200 mA.

CrossCheck GPRS Power
The CrossCheck GPRS operates on input voltages from 9–32 VDC.
The low-noise amplifier integrated on the GPS antenna draws power
from the CrossCheck GPRS through the antenna cable. The
CrossCheck GPRS does not require any special power-up or down
sequencing.
The CrossCheck GPRS’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 protects against excessive current.
For more information on the CrossCheck GPRS power requirements,
see Appendix A.

Power and I/O Cable
Note – Trimble recommends installing the power and ground leads as
close to the battery as possible to ensure that the CrossCheck GPRS is
connected to the cleanest possible source of power.
Warning – The CrossCheck GPRS requires a 2A fuse to be installed in its
power cable (Vbatt). A 2A fuse and fuse holder is supplied with the
Power/Data cable P/N 46598. Install the fuse holder and fuse as close as
possible to the vehicle battery.

Installation
The CrossCheck GPRS is protected against both input power overvoltage and reverse polarity. 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 GPRS operates continuously only when the vehicle
is running. When the ignition is off, the CrossCheck GPRS 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
GPRS is the following:
54
•
When the ignition is OFF, the unit goes to sleep state after
15 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 connection (see Figure 2.29), the
CrossCheck GPRS operates and draws power continuously, even
when the vehicle is not running:
56
•
Idle mode (not transmitting) without the EchoLDX Message
Terminal, 150 mA is typical @ 12 VDC
•
Idle mode (not transmitting) with the EchoLDX Message
Terminal, 220 mA is typical @ 12 VDC
Caution – When using the Continuous Power connection, the
CrossCheck GPRS may drain a car battery in a vehicle that is not
running in 1 to 3 weeks, depending on the battery size, quality, and
remaining life span. In the Continuous Power connection, the
CrossCheck GPRS can also drain the battery of a vehicle that is not
running long enough to compensate for the current draw of the
CrossCheck. Observe extreme care when using this connection
option. The CrossCheck GPRS will automatically power off when the
voltage drops below 9 VDC.

When the CrossCheck GPRS’s ignition input and power inputs are
activated:
•
The LEDs blink once.
•
Both turn off for approximately 5 seconds.
The GPS LED is on for approximately 2 seconds, then blinks until the
first position fix is computed. The GPRS LED blinks until the unit is
registered with a GPRS network, at which point the GPRS LED
turns on.

CrossCheck GPRS 1900 Installation Manual
Operation
3.3
GPS Receiver Operation
At power-up, the GPS receiver initializes with the last-known position
if one is available. Using this information, the GPS receiver acquires
satellite signals.
•
During the satellite acquisition process—which normally
requires less than 45 seconds—the green GPS LED blinks.
•
Once three or more satellites are acquired, the GPS receiver
computes positions, course, and speed, 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.
Note – If the CrossCheck GPRS unit does not have a valid last-known
position, the unit will be forced to perform a cold start which normally
requires less than 3 minutes. For example, this would happen the first
time the unit is turned on, or if the unit has never been on long enough
to obtain an Almanac. To obtain an Almanac, the unit must track GPS
satellites for up to 30 minutes.
