1.2 CrossCheck GSM Applications
Trimble Mobile Positioning & Communication (MPC) provides you
with the core products around which you can build systems and
applications for managing your transport and logistics assets.
MPC products 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
software installed at the fixed base station.
The on-board components are centered on the CrossCheck GSM, (the
GPS receiver with integrated
IQ
Event Engine
and a GSM phone). You
can use the CrossCheck GSM 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.
Optional external units include a Mobile Data Terminal (MDT) to
provide a driver interface to exchange messages or generate manual

event reports, and a handset for use where voice communication is
required.
You can use the Trimble FleetVision software package at the base
station, as a standalone fleet management system or as the
communications platform for an integrated system. FleetVision
features include event and alarm reporting, data handling, as well as
map displays, allowing you to view the positions of mobile assets in
real-time or replayed for analysis purposes. FleetVision includes an
External System Interface (ESI) package. This gives system
integrators and application developers the ability to customize the

Overview
1.4 Global Systems for Mobile Communications
Cellular mobile telephone systems have been widely available
throughout the world. However, because cellular mobile telephone
systems are regulated at the national level, these systems are not
generally compatible with each other. To resolve this dilemma of
being able to communicate from almost anywhere, but only within
your own system, The European telecommunications operators (the
Conference of European Postal and Telecommunications
Administration, or CEPT) designed a new mobile telephone network.
This network has evolved into GSM, and CEPT has turned over
management of GSM to the European Technical Standards Institute
(ETSI). GSM is the predominant mobile communications system
throughout Europe and GSM is also widely available throughout the
world.
1.4.1 GSM Cellular Phone System
The Global Standard for Mobile (GSM) protocol offers a variety of
data services that allow users to send and receive data at rates of up to
9600 bps. Data may be delivered over ISDN, Packet Switched or
Circuit Switched Data Networks (PSDN or CSDN) and via the Short
Message Service (SMS).
SMS is a store and forward service for the bi-directional exchange of
alphanumeric messages of up to 160 characters.
Architecture of the GSM network
An Automatic Vehicle Location (AVL) or Asset Management System
based on GSM consists of several distinct components. The
Crosscheck GSM is the mobile unit that is installed in the vehicle and
contains the Subscriber Identity Module (SIM). The SIM card
contains a unique International Mobile Subscriber Identity (IMSI)
number. This enables the network to identify the user and therefore
allow the terminal to have access to specific, subscriber services.
The GSM “cloud” is made up of two sections:
1-8 CrossCheck GSM Operation Manual
Overview
•
The Base Station Subsystem that controls the radio link with
the mobiles through local cells
•
The Network Subsystem that controls the switching of calls
between the network users, mobile to mobile, and between
mobile and fixed lines
The Network Subsystem stores all administrative information
including the current cell being used by the mobile unit which allows
call routing and the roaming ability of GSM. An important feature of
GSM is this ability to move across international and network borders,
a feature that is described as “roaming.” If arrangements have been
made with the service provider, the SIM card will be enabled for
roaming.
•
Mobile Station (MS)
•
CrossCheck GSM includes a radio transmitter, receiver
and voice encoder, decoder. The optional Voice Upgrade
Kit includes a handset.
•
Subscriber Identify Module (SIM)—an electronic card
containing a computer chip. The chip contains the
subscriber information and operating system parameters.
SIMs provide authentication, encryption, information
storage, and subscriber account protection services
(including Personal Identification Number or PIN, and Pin
Unblocking Key or PUK). GSM users can move the SIM
from one CrossCheck GSM to another.
•Other network components
•Voicemail System (VMS)— delivers messages and pages
to GSM users.
•Short Message Service Center (SMSC)—delivers text
messages (up to 160 characters) to GSM users.
•Executable Short Message Platform—delivers commands
to the SIM card via an over-the-air interface.

Overview
1.5 The Global Positioning System
The Global Positioning System 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.
1.6 GPS Receiver
The CrossCheck GSM 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 below.
The CrossCheck GSM’s GPS receiver features an eight-channel
digital signal processor (DSP) which operates at the GPS L1
frequency (1575.42 MHz) and processes the AcquisitionCoarse/
Acquisition
(C/A) code portion of the GPS signal. The RF and digital signal
processing components of the GPS module are custom ASICs
designed by Trimble.
1-12 CrossCheck GSM Operation Manual
Overview
1.7 GSM Operation
At power up the CrossCheck GSM automatically searches for a GSM
network using a set of tables on the SIM card to determine which
GSM network the phone should try to reach. These tables are the
Public Land Mobile Network (PLMN) tables and each GSM network
has its own unique PLMN number. This number is the Mobile
Country Code (MCC) and the Mobile Network Code (MNC), which
are also the first numbers of the subscriber’s IMSI. (The IMSI is the
MCC, plus the MNC, plus the MSIN.)
The PLMN table finds either the subscriber’s home network or a
network that will allow service, and registers to the network
consistent with the handset. The responding network’s MSC passes
this request for service to the VLR. If the VLR has information about
this IMSI, then it passes the request to the AUC for authentication. If
the VLR cannot find any information on this IMSI, it must pass the
request to the HLR and get approval before passing on the request.
Once the VLR has approval to grant the request for service, it knows
the user identity, what features are authorized, and the authentication
codes (from the AUC). The VLR then passes the request back to the
MSC for routing to the number being called.
If the number being called is a land-based number, the MSC passes
the call to the Public Switched Telephone Network (PSTN) for
connection. If the number being called is another mobile number, the
MSC repeats the process described above to locate the number being
dialed. Depending on services supported, the call will be answered, be
routed to voicemail, be intercepted by a live answering service, or
simply time out with the message that the number being dialed is not
available. In any case, the transmission is digital and encrypted so
information cannot be intercepted easily.

2.4 Mounting the CrossCheck GSM
The CrossCheck GSM 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 GSM can be installed on the floor under a
seat or on a wall behind a seat. (The CrossCheck GSM cannot be
installed inside the engine compartment, wheel well, chassis, or on
any exterior surface of the vehicle.)
Choose a location for the CrossCheck GSM which allows for
convenient routing and connection of the antenna and interface cables,
CrossCheck GSM Operation Manual 2-7
Installation
and which has access to a power source. When selecting a mounting
location, consider the specifications listed in Appendix A, Table A-8,
and avoid the following hazards:
•Direct exposure to weather
•Excessive heat (for example, exhaust manifolds)
•Excessive cold (for example, refrigeration units)
•High vibration areas (engine compartment, transmission)
•Corrosive fluids and gases (acids, petroleum products)
•Direct exposure to water (the CrossCheck GSM is not
waterproof)
To mount the CrossCheck GSM:
1. Choose the mounting location.
The CrossCheck GSM can be mounted horizontally, vertically,
or in any convenient orientation protected from moisture.
During normal system operation, the user does not need to see
the CrossCheck GSM LED indicators. However, the ability to
see the LED indicators is a definite advantage when
troubleshooting the unit.
The integral mounting flange is designed to secure the
CrossCheck GSM 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. Figure 2-4 shows the mounting
dimensions.

The installer must provide an appropriate selection of fasteners
to secure the CrossCheck GSM to the mounting surface.
a. 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.
b. When using machine screws, select a screw length which
extends a safe distance beyond the mounting surface, and
secure the screw with a washer and nut. Lock washers are
recommended to prevent vehicle vibration from loosening
the fasteners.
In general, Trimble Navigation recommends the use of number
m3.5 (or number 6) pan head machine screws.

Caution – Use washers sized small enough that they do not tighten
down on the plastic cover of the CrossCheck GSM when the mounting
screws are secured. Otherwise, over stressing the plastic mounting
surface when tightening the mounting screws can cause the plastic to
crack. Tightening screws without using washers can lead to
compressing, cracking, or deforming the mounting surface.
2.4.1 Connecting CrossCheck GSM to the Vehicle Chassis
For proper operation, the aluminum chassis of the CrossCheck GSM
must be connected electrically (grounded) to the chassis of the vehicle
on which it installed. This can be accomplished by:
•Direct connection through metal screws (preferred), or
•Using the chassis ground wire
Direct Connection through Mounting Screws
Mount the CrossCheck GSM 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). Fasten down the CrossCheck GSM
mobile unit using metal screws driven through the metal tabs on the
sides of the unit. Make sure the screws are tight, and that they make
contact both with the metal on the CrossCheck GSM and with the
vehicle chassis. Use star washers to ensure a reliable electrical contact
to the metal tabs.
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 CrossCheck GSM should be left
unconnected.
2-10 CrossCheck GSM Operation Manual
Installation
Connection through the Chassis Ground Wire
If the CrossCheck GSM unit 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. Use a wire with gauge of at least 18
AWG to connect the CrossCheck GSM power connector to the
vehicle chassis. Keep the wire length as short as possible by selecting
a connection point in the vehicle chassis that is close to the
CrossCheck GSM unit. Use a metal screw with a star washer to ensure
a reliable electrical contact to the vehicle chassis.
2.5 Choosing the GPS Antenna Mounting Location
Antenna location is critical for optimum GPS performance. Choose a
location for the GPS antenna with an unobstructed view of the sky,
and which is safe from damage during normal vehicle operation and
maintenance. GPS satellite signals do not penetrate metal or dense
wood. GPS signals can penetrate plastic, glass and tinted glass (except
metalized glass), fiberglass and plexiglass materials as long as the
surface is relatively dry.
Caution – Never mount the GPS antenna under a metalized glass
windshield, such as those used in some vehicles for window
de-fogging or de-icing systems. The GPS antenna can be mounted
under a tinted-glass windshield.
When selecting a location for the GPS antenna, ensure that the
antenna is not shielded from satellite signals by metal objects or other
impenetrable materials. For optimal GPS performance, the antenna
location should have a clear view of the sky.
CrossCheck GSM Operation Manual 2-11
Installation
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
GSM, including combined GPS/GSM cellular antenna solutions which
have not yet been tested and certified by Trimble.
Mount the antenna in a horizontal position (see Figure 2-5 on page
2-12), facing the sky. If the antenna must be located in the vicinity of
other antennas (radio, cellular phone), locate the GPS antenna at least
46 centimeters (approximately 18 inches) 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 meters (or
approximately 16 ft.). Longer bulkhead-mount antenna cables can be
prepared by the installer using the guidelines presented in
Appendix A, Specifications.
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.

To mount the Magnetic GPS Antenna:
1. Choose the antenna mounting location (see Choosing the GPS
Antenna Mounting Location on page 2-10).
2. Mount the antenna to a ferrous surface. The antenna can be
mounted on the exterior of the vehicle or in the vehicle’s
interior.
3. Route the antenna cable. The antenna features a permanent
antenna cable which must be routed to the location where the
CrossCheck GSM is mounted. For detailed cable routing
guidelines, see Routing the GPS Antenna Cable on page 2-20.
Caution – The magnetic-mount antenna cable is exposed to the
environment. Since wind could cause the cable to whip around, use
tie wraps to secure the cable along its route.
2-20 CrossCheck GSM Operation Manual
Installation
Caution – The magnetic-mount antenna cable has no strain relief at
the antenna end of the cable and is not recommended for permanent
installations.
2.6 Routing the GPS Antenna Cable
The Magnetic GPS Antenna has an integral antenna cable, and the
Miniature Bulkhead GPS Antennas have a separate 5 meter (or
approximately 16 ft.) cable. If you are using one of the Miniature
Bulkhead GPS Antenna units, attach the antenna cable to the SMA
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 GSM while avoiding the following hazards:
•Make sure that at least two inches of clearance exists between
the CrossCheck GSM’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 one-half inch bend
radius.
•Provide an adequate service loop when routing the cable
around vehicle hinges to ensure that the cable is not
inadvertently 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 GSM GPS (SMA) connector.

2.7 Choosing a GSM Antenna Mounting Location
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.
If you are installing multiple antennas, maintain a separation of at
least 46 centimeters (or approximately 18 in.) between the cellular (or
other) and GPS antennas (see Figure 2-12). If you are using a
combination GPS/cellular antenna, maintain a separation of at least
46 centimeters (or approximately 18 in.) between the combination
antenna and any other antennas.

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 can substitute a glass-
mount antenna as long as it conforms to the requirements listed in
Appendix A, Specifications.
2.7.1 Routing the GSM Antenna Cable
The next step in the installation process is routing and connecting the
antenna cable to the CrossCheck GSM. When routing the cable, start
at the antenna and choose the most direct path to the CrossCheck
GSM while avoiding the following hazards:
•Sharp bends or kinks in the cable.
•Excessive heat.
•Exposure to corrosive fluids.
•Never coil the excess antenna cable, particularly the cellular
antenna cable. A coiled cable can act as an antenna and may
receive interference.
•Provide an adequate service loop when routing the cable
around vehicle hinges to ensure that the cable is not
inadvertently 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.
Caution – If your cellular antenna cable is exposed to the
environment, wind could cause the cable to whip around. Use tie
Caution – A minimum separation distance of 20 cm must be maintained between the antenna and
persons 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.

2.8.1 Inputs (IP0 to IP3)
The CrossCheck GSM unit supports four discrete inputs. The circuit
diagram is shown in Figure 2-14.
Figure 2-14 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
GSM can be configured to detect either logic high or logic low states
at the inputs whenever the unit is powered on.
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
GSM detects the input.

Note – The CrossCheck GSM can be configured to detect only a logic
low (grounded) input when it is powered off and in power
management mode.
The discrete inputs are compatible with properly connected relays and
switches or with standard 3.3 volt 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.
The input must be held in a particular logic state for at least 200 msec
(configurable up to 1 second) so the CrossCheck GSM can detect it.
2.8.2 Outputs (XP0 to XP2)
The CrossCheck GSM features three discrete outputs (XP0-XP2) for
driving external devices such as relays. When inactive (default 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 milliamps. Figure 2-15
shows a diagram of a discrete output.

2.9 Connecting a Computer or Mobile Data Device with
the Serial I/O Cable
The D-9 connector is an RS-232 (receptacle) DCE (Data
Communication Equipment) serial port, making it compatible with
most personal computers and Mobile Data Devices.
You can configure the MDT/Aux port with the TAIP MT command.
(For more information on TAIP commands, refer to the TAIP/IQEvent
Engine Reference Manual.)
The MDT port supports the following modes:
•Normal—Supports any combination of TAIP, TSIP, and NMEA
protocols
•PAD—All input is converted into TAIP TX messages, all
output is text stripped from TX messages
•AT—Traffic consists of AT commands and data from the MDT
device to GSM, and GSM responses to the MDT device from
the CrossCheck GSM
The MDT inputs (Rx) accept –3 to –15 VDC. A low input signal is
less than -3VDC (typical). A high input signal is greater than+3VDC.
The MDT outputs (Tx) range from –5 volts to –8 volts, depending on
the load.
Note – During normal operation, the MDT/Aux service port
communicates with a PC or Mobile Data Device using TAIP messages
(see Chapter 5, IQEvent Engine Overview and the IQEvent Engine/
TAIP Reference Manual for detailed information) at 9600 bps, 8-N-1,
and no flow control. The baud rate and other communications
parameters can be set to match the PC or Mobile Data Device
settings.

2.10 CrossCheck GSM Power
The CrossCheck GSM operates on input voltages from 9-32 VDC.
The low noise amplifier integrated on the GPS antenna draws power
from the CrossCheck GSM through the antenna cable. The
CrossCheck GSM does not require any special power up or down
sequencing.
The CrossCheck GSM’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.
See Appendix A, Specifications, for more information on the
CrossCheck GSM power requirements.

The CrossCheck GSM is protected against both input power over-
voltage and reverse polarity. The primary power cable has a built-in 2-
amp 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.
Note – The CrossCheck GSM (including the cellular phone) will power
down automatically when input voltage drops below 9V or exceeds
32V, see the input power specification in Appendix A. IQEvent Engine
signals for under- and over-voltage are available, with default values
of 9.5V and 31.5V respectively.
For configurations, refer to the TAIP PM message description in the
TAIP/IQEvent Engine Reference Manual.
2-34 CrossCheck GSM Operation Manual
Installation
2.10.1 Connections For Power Management
For the Power Management configuration, the CrossCheck GSM
operates and draws power (150 milliamps nominal) continuously only
when the vehicle is running. When the ignition is off, the CrossCheck
GSM responds to the change in the state of the Ignition Sense lead
and goes to sleep (at programmed intervals), drawing reduced power
(<10 milliamps).
When IQEvent Engine is configured for power management, the
CrossCheck GSM can be scheduled to wake up periodically, typically
long enough to refresh its GPS position) or could wake up when
triggered by an external signal or GSM Ring, and then go back to
standby mode. Therefore, even though the CrossCheck GSM is
drawing power while awake, its duty cycle is a fraction of what it
would be under continuous power, and battery life is extended. For
additional information, refer to PM Message in the TAIP/IQEvent
Engine Reference Manual.

Configuration
3.4 Initializing the CrossCheck GSM Unit
This section discusses how you configure your Subscriber Identity
Module (SIM), program your GSM PIN and calling options, and set
the TAIP ID.
3.4.1 SIM Configuration and Activation
To operate CrossCheck GSM, you need a SIM card. A SIM is a
“smart” card containing a microprocessor and associated logic. It is
about the size of a postage stamp. SIMs can be obtained from a
network provider, a service provider, or from a mobile phone shop.
When you obtain a SIM, make sure that it is configured for data and
voice operation, as well as SMS services that normally come with
GSM cellular service.
You need a data number if the circuit switched connection is to be
made from a land line connection (PSTN/ISDN). However, a voice
number is sufficient if the circuit switched connection is between two
GSM units (CrossCheck and GSM phone at the base). In this case, the
voice number supports voice, SMS, and circuit switched modes.
You can use SMS for simple reporting, either querying from the base
or exception reporting from the mobile unit. It should not be used for
lengthy sessions, such as log download.
The SIM card is the true identity of any GSM phone (including a
CrossCheck GSM) as far as the mobile network is concerned. Once
you have obtained a SIM card, the network you have chosen may
require that you set a PIN (Personal Identification Number), which is
a four to eight digit number that can be used to protect the SIM from
unauthorized use. You can set the PIN on the SIM by putting the SIM
into a standard mobile phone and using that phone's PIN setting
ability.
You will also need to supply the PIN to the CrossCheck GSM unit as
it will be initializing the SIM on your behalf. Trimble recommends
setting the PIN in the CrossCheck GSM unit before inserting the SIM,
as this avoids having old PINs rejected by the SIM (see below). The
3-6 CrossCheck GSM Operation Manual
Configuration
PIN is set using the PC message (>SPCGE;PIN=x...x<) as
described in Programming the GSM PIN and Calling Options on page
3-8.
Having set the PIN, Trimble recommends that you:
1. Verify that the PIN is correct, (>QPC<).
2. Remove power from the CrossCheck.
3. Insert the SIM.
4. Apply power to the unit.
The supplier of your SIM will probably provide additional
information. If you intend to send SMS (Short Message Service)
messages, make sure you are provided with an SCA (Service Center
Address). This is the telephone number of an SMSC (Short Message
Service Center) and is required by the CrossCheck GSM in order for
it to send SMS messages. (Set it using the
>SPCGE;SCA=nnnnn...< command where nnnnn is the SCA).
Typically, each network provider has one or more SMSCs. Please be
aware that there are some reports of SMS interoperability issues
between some networks or subnetworks, but these are few and there
should not be a problem if you are operating within a single network.
Warning – Incorrect entry of the PIN could cause the SIM to be
blocked. For more information on blocked SIMs, see SIMs and the
Network.
3.4.2 SIMs and the Network
The SIM controls network access by verifying that the PIN it contains
matches the PIN supplied by the CrossCheck GSM firmware. If the
numbers do not match, or if the SIM is not inserted in the CrossCheck
GSM, the amber GSM LED fast blinks and one of the following
messages is output to the MDT port:
>SPCGE;SIM=PIN ERR< - PIN in PC message does not match SIM
>SPCGE;SIM=BLANKPIN< - PIN field in PC message is empty
CrossCheck GSM Operation Manual 3-7
Configuration
>SPCGE;SIM=ABSENT< - SIM card is not present
Access to the GSM network is then prevented. Once a PIN mismatch
occurs, the CrossCheck GSM firmware will not attempt to initialize
the SIM with its PIN (even after a power cycle) until another set pin
command (>SPC...<) has been entered. This is done to prevent the
SIM being “blocked” (see below). After a PIN mismatch, subsequent
CrossCheck GSM resets causes the GSM LED to fast blink, and the
following message is displayed at the MDT port:
>SPCGE;SIM=PIN ERR<
Once a new set PIN command has been entered, the CrossCheck
GSM firmware attempts once more to initialize the SIM with the PIN.
This occurs even if an identical PIN is entered in the set PIN
command to allow for the condition where the PIN is correct but an
incorrect SIM was inserted.
Warning – After three consecutive PIN errors, the SIM will be
“blocked.” If this is the case, the Comms LED on the CrossCheck
GSM fast blinks, and the following message is output to the MDT port:
>SPCGE;SIM=PUK REQ<
You will now have to supply a PUK (Personal Unlocking Key). You
will need to obtain this eight digit number from the network operator.
To enter this number, you will need to place the SIM in a standard
mobile phone and use its PUK capabilities.
After ten consecutive wrong entries of a PUK, the SIM will be
permanently blocked from GSM operation. A permanently blocked
SIM will cause the CrossCheck GSM unit amber LED to fast blink,
and the following message is displayed at the MDT port:
>SPCGE;SIM=FAILED<
You can check the status of the SIM at anytime by using the query:
>QPC;SIM=<
3-8 CrossCheck GSM Operation Manual
Configuration
3.4.3 Further Information
There are a variety of sources of further information (for example, the
use of PIN2, number lockouts, and PC utilities for configuring SIMs),
particularly on the web. Trimble recommends that you do a web
search for this information as it is continuously changing. ETSI is a
good source of definitive material (http://www.etsi.org at the time of
writing), as is the GSM association (http://www.gsmworld.com at the
time of writing).
3.4.4 Programming the GSM PIN and Calling Options
Enter the cellular PIN using the TAIP PC message:
>SPCGE;PIN=x...x<
where x...x is the PIN currently defined for the SIM that is inserted
in the CrossCheck GSM’s SIM slot. If no PIN is defined for the SIM
card, you do not need to enter a PIN. Once a PIN is entered, it is
maintained in non-volatile (battery-backed) memory, and is used on
each CrossCheck GSM power up to initialize the GSM module.
Whenever the SIM card is changed, the PIN must be re-entered.
Note – Due to factory default settings, messages received from the
CrossCheck GSM always include the unit’s Vehicle ID and an
appended checksum. For brevity, these two parameter settings are
ignored in the examples below.
Factory Defaults
To query the CrossCheck GSM for the current configuration, send the
following message:
>QPC<
A new CrossCheck GSM (out of the carton) responds with a message
containing the factory default parameter settings for the protocol
configuration:
CrossCheck GSM Operation Manual 3-9
Configuration
>RPCGE;RADIO=26;RX=ALL;TX=CSW,PSTN,DTRDCD,
0,500,1500;SCA=; PIN=; TRACE=0;
BRN=0060,04;BRA=0060,04;ALH=1;ROUTE=0<
The Protocol Type is always set to G (GSM) and the Protocol Enable
Flag is always set to E (Enabled).
For Circuit Switched calls, the BRN and BRA parameters allow
adjustment of the CrossCheck GSM’s built-in scheme for retry
attempts when a circuit-switched (CSW) call to the base station
cannot be connected. The BRN parameters adjust the retry scheme for
Normal connections (when no alarm messages are queued), and the
BRA parameters adjust the retry scheme for Alarm connections
(when at least one alarm message is queued).
Note – When CrossCheck GSM is in Circuit Switched Data mode, it
can support either PSTN or ISDN connections. Contact your network
operator for information on which connection is supported.
Parameters consist of a back-off time (in seconds) and a maximum
number of retries. The back-off time specifies only the time until the
first retry attempt; subsequent retry times are determined by the back-
off / retry algorithm. For detailed information, refer to Back-off/Retry
Algorithm in the TAIP/IIQEvent Engine Reference Manual.
Note – For detailed information about message queue operation, see
Destination Addresses and Message Queuing in the TAIP/IQEvent
Engine Reference Manual.
For CSW calls, ALH is one of three Alarm mode parameter settings.
These modes determine how Alarm messages are processed when an
active CSW call is in progress. For detailed information about
selecting an Alarm mode (ALH), see Alarm Handling in the TAIP/
IQEvent Engine Reference Manual.
For detailed information about each message parameter, refer to PC
Message in the TAIP/IQEvent Engine Reference Manual.

3.4.5 Setting the TAIP ID
To set the TAIP ID, you need to send the ID message with the S
qualifier. Each CrossCheck GSM should be assigned a unique
alphanumeric ID to give the vehicle a unique identity. To set the ID to
CA20, enter the following message:
>SIDCA20<
The CrossCheck GSM should reply with the following response:
>RIDCA20<
Note – The CrossCheck GSM will accept a TAIP ID of between four
and eight digits. However, FleetVision will accept only four digits. If
you are using FleetVision, the TAIP ID must be four digits.
CrossCheck GSM Operation Manual 3-11
Configuration
3.4.6 Circuit-Switched versus Short Message Service Mode
Circuit-Switched (CSW) calls rely on connection-oriented
communications for sending data between parties. A typical CSW call
occurs in a data transfer between two computers. The calling
computer sends its call request through a modem, which sets up the
call to the modem connected to the receiving computer. Once the
connection is established, the data is transferred between the modems.
Short Message Service calls do not require a connection to the party
being called. Instead of setting up a connection between two parties,
SMS messages go to a SMS center (SMSC). This central processing
facility then buffers the message until the recipient phone becomes
active.
While CSW data is a modulated and demodulated signal, SMS is a
alphanumeric message containing up to 160 characters - much like a
pager message.
CSW mode is efficient for large volumes of data, while SMS is best
for short messages.
CrossCheck GSM can be configured to use SMS to provide cost-
effective data transfer capabilities.

3.5 Testing the Handset Installation
The CrossCheck GSM should be tested in both handset and hands-
free voice mode before finishing the installation. For detailed
instructions, see Programming the GSM PIN and Calling Options on
page 3-8.
3.5.1 Service Provider Configuration
You need to select a GSM service provider, purchase a SIM, and have
the service provider initialize your SIM. The SIM should be
initialized for voice (Circuit Switched Communications), and for
SMS (Data Services) if desired.
3.5.2 Voice Mode Test
To test the Voice mode:
1. Place a call to a test number.
2. Test the handset and hands-free modes to assure proper
operation during the call.
3. End the call and have someone call your cellular phone
number.
4. End the call.

Once the installation and configuration are completed, the
CrossCheck GSM is ready for operation. When power is applied, the
CrossCheck GSM can then operate automatically without user
intervention, based on its IQEvent Engine configuration.
This chapter provides a basic overview of the CrossCheck GSM’s
operation, including:
•LED Indicators
•GPS Receiver

Operation
4.1.3 LED Power-on Sequence
When the CrossCheck GSM’s ignition input and power inputs are
activated, both LEDs blink once, turn off for approximately five
seconds, then are on for approximately two seconds.
The GPS LED is on for approximately two seconds, then blinks until
the first position fix is computed. During this period, the GSM LED
blinks until the unit is established in a GSM area, at which point, the
GSM LED turns off. When a call is active, the GSM LED stays on for
the duration of the call.
When the first position fix is computed, the GPS LED turns on
continuously. Afterwards, the GPS LED remains on when computing
position fixes or blinks when no position fixes are computed. The
GSM LED turns on when a GSM connection is in progress, turns off
when no call is in progress, and blinks if no GSM coverage is
available or call has not been established.
4.2 GPS Receiver Operation
At power-up, the GPS receiver is initialized with the last known
position. Using this information, the GPS receiver acquires satellite
signals. During the satellite acquisition process, which normally
requires less than two 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 two seconds.

Operation
4.3 GSM Operation
When the GSM LED (amber LED) is off, it means that the unit is
registered with the network or in Standby mode. If the CrossCheck
GSM is not registered with the network, the LED will blink, and when
a data or voice call is in progress, the LED stays on.
The LED indicators are also a useful diagnostic tool. See LED
Diagnostic Errors, page 6-9 for more information.

5IQEvent Engine
Overview
TheIQEvent Engine (IQEE) manages the operation of the
CrossCheck GSM and allows intelligent, autonomous reporting to a
base station, to an internal log for later retrieval, or to the MDT/Aux
port. By selectively transmitting its position and status only when
user-defined events occur the CrossCheck GSM can provide much
more specific data for fleet and mobile asset management, while
significantly reducing communications costs.
TheIQEvent Engine is highly configurable and can be tailored to a
wide variety of AVL applications. Its event-based reporting engine
can trigger events and event actions based on user-configurable
specifications. Thus CrossCheck GSM operation can be automatically
changed to react to real-time conditions in the vehicle.
TheIQEvent Engine utilizes the following elements to manage
CrossCheck GSM operation.
•Event Engine—monitor configured event triggers, generate
events, initiate event actions
•Wireless Communications—queue messages to selected
destinations, establish communications, and handle retries
when wireless communications are busy or unavailable
•Data Log—store and retrieve event, status, and configuration
data in internal Data Log
•MDT Interface—Integrate a mobile data terminal or other data
device to pass data to/from custom software at the base station
5-2 CrossCheck GSM Operation Manual
IQEvent Engine Overview
•Discrete I/O—monitor external device inputs as event triggers
and allow control of external devices based on IQEE events
•Power Management—provide configurable power-saving
strategies
•Password Protection—allow secure access to CrossCheck
GSM configuration and status data
The following paragraphs contain a brief description of these
elements and the associated TAIP message(s) used for configuration
and status. For a detailed description of IQEvent Engine and the
TAIP protocol (IQEE’s native protocol), please refer to the TAIP/
IQEvent Engine Reference Manual.
5.1 Event Engine
The Event Engine is a simple yet powerful tool to intelligently react to
real-time conditions in the vehicle and control CrossCheck GSM
reporting and internal operation. It monitors a set of trigger signals,
evaluates user-configured events, generates event reports, and initiates
other user-specified event actions. Its power comes from its
configurability (event triggers and actions are completely user-
specified) and its self-modifying capability (event actions can enable
or modify the current configuration).
5.1.1 Event Triggers
An event definition contains a set of conditions or triggers that cause
an event to occur. The elemental triggers are listed below, but events
are typically triggered by a Boolean combination of triggers. For
example, an event could be defined to occur when the vehicle enters
or leaves a specified region while cellular coverage is available and a
discrete input is active. The following elemental triggers are available:
•Position inside/outside a region
•Time elapsed and/or distance traveled
CrossCheck GSM Operation Manual 5-3
IQEvent Engine Overview
•Time of day, date
•Speed
•Heading
•Ignition on/off (depending on power wiring)
•Discrete Input/Output signals active/inactive
•Counter reaches a specified number
•Data received on MDT port
•Data log over/under 80% full
•GPS status (position fix, antenna connected)
•Communications status (available, roaming, open data
connection)
•Power management status (active, about to sleep, reason for
wakeup)
•User Flags true/false
•Battery voltage low/high/OK
5.1.2 Event Reports and Event Actions
An event definition specifies an event report and/or other action to
occur when the event is triggered. Event reports can be routed to a
base station via wireless communications, to the CrossCheck GSM’s
MDT serial interface, or to the Data Log.
In addition to event reports, other event actions can be specified.
These actions can modify the behavior of the CrossCheck GSM and
also modify the configuration of events and event triggers. For
example, an event that occurs at 8 AM each day can set the Power
Management configuration for a 15 minute cycle, and a
complementary event that occurs at 5 PM each day can set the Power
Management configuration for a 2 hour cycle, thus adjusting
CrossCheck GSM power consumption according to expected use.
Another example can accumulate the length of time a vehicle spends
5-4 CrossCheck GSM Operation Manual
IQEvent Engine Overview
in a particular area. An event that occurs when entering a region can
start/resume a timer, and a complementary event that occurs when
exiting a region can stop/suspend the timer.
The following are examples of typical event actions:
•Report event with position & time to base, MDT, or Data Log
•Turn an output device on/off
•Start/stop/suspend/resume a timer
•Start a distancer
•Start/increment a counter
•Set a user flag to true or false
•Alter an event definition
•Alter a trigger configuration
•Alter power management configuration
Events are configured via the TAIP ED message.
5.2 Wireless Communications
The CrossCheck GSM’s wireless communications channel is used to
exchange data with one or more base station locations. It can be used
in polled mode, where query/response sequences are initiated by a
base station, and in autonomous mode, where IQEE-generated event
reports are delivered to up to 10 destinations.
The CrossCheck GSM allows configuration for Circuit-Switched or
packet-switched (SMS) communications.
In polled mode, responses to queries are returned to the caller via
open circuit-switched connection, or via SMS message to the
originator of the SMS query.
In autonomous mode, up to 10 destinations can be configured, each
with an associated Destination Address (phone number) and out-
bound message queue. The message queues draw from a single
CrossCheck GSM Operation Manual 5-5
IQEvent Engine Overview
memory pool, so an accumulation of messages in one DA queue
reduces the number of messages available for other DA queues.
When an IQEE event is generated, the event report is placed in the DA
queue configured for that event. The configured event priority
determines the priority of the DA queue, and the DA queue priority
determines whether an immediate call is made to deliver the messages
in the queue. The configurable priority levels are
•Alarm—A DA queue is marked as an Alarm queue when at
least one Alarm message is contained in the queue. When a DA
queue becomes an Alarm queue, a call is initiated to deliver the
messages in the queue. Alarm queues take precedence over
Normal queues. Additionally, an Alarm Handling Mode can be
configured to re-route an alarm message to an open connection
or to preempt an in-bound connection.
•Normal—A DA queue is marked as a Normal queue when at
least one Normal message and no Alarm message is contained
in the queue. When a DA queue becomes a Normal queue, a
call is initiated to deliver the messages in the queue.
•Low—A DA queue is marked as a Low priority queue when
only Low priority messages are contained in the queue. A Low
priority queue accumulates messages without initiating a call.
The CrossCheck GSM provides built-in schemes for retry attempts
when a circuit-switched call to a Destination Address cannot be
connected. Separate retry schemes are provided for Normal
connections (when no alarm messages are queued) and for Alarm
connections (when at least one alarm message is queued).
Configuration parameters allow adjustment of back-off times and
maximum number of retries. When the retry limit is reached, no more
attempts are made until a new message enters the queue or until the
CrossCheck GSM unit is reset (power cycle or Power Management
shutdown/wakeup).
The Wireless Communications channel is configured via the TAIP PC
message.
5-6 CrossCheck GSM Operation Manual
IQEvent Engine Overview
5.3 Data Log
The IQEvent Engine maintains a Data Log in non-volatile, battery-
backed memory.
The Data Log is a circular log, where new entries overwrite the oldest
log entries.
The following types of data can be directed to the Data Log:
•IQEE Event Reports containing an event number and the GPS
location and time associated with the event.
•TAIP TX messages routed from MDT input
• IQEE configuration and status data generated by Event
Actions (TAIP queries) for example, counter values, timer
values, discrete I/O states, configuration parameters.
Data Log entries can be retrieved and erased via a wireless comms
connection or via the MDT serial interface. A facility is available to
allow recovery from interruptions in lengthy retrieval sessions.
Data Log control and retrieval is accomplished via the TAIP DL
message.
5.4 MDT Interface
The CrossCheck GSM MDT interface allows connection to an
external serial device, such as a PC/laptop or message terminal. The
MDT interface can be configured in the following modes:
•Normal mode—In Normal mode, the MDT interface is used
for CrossCheck GSM configuration and status. The default
protocol is TAIP, which is the IQEvent Engine native protocol.
IQEE can be configured, events can be reported, and Data Logs
can be retrieved via TAIP messages. Other selectable protocols
are TSIP and NMEA.
•PAD mode—In PAD (Packet Assemble/Disassemble) mode,
message text can be input to the CrossCheck GSM and output
CrossCheck GSM Operation Manual 5-7
IQEvent Engine Overview
from the CrossCheck GSM. All text input is partitioned into
packets (according to PAD mode selections) and inserted into
TAIP TX messages for routing to a base station or to the Data
Log. TX messages received from a base station (or generated
by IQEE and routed to the MDT) are stripped of their TAIP
“wrapper.” and the remaining text data is output to the MDT.
•AT command mode—In this mode, the MDT interface
becomes an interface to the CrossCheck GSM’s internal GSM
Comms module. The Comms module can then be used as a data
modem. An AT command/response dialog can be used to set up
data connections and transfer data via the GSM network.
Configuration of the MDT interface is controlled by the TAIP MT
message.
5.5 Discrete I/O
TheIQEvent Engine provides discrete I/O support to trigger events
and send control signals to external devices.
Discrete inputs are de-bounced and transitions are registered once per
second to provide Event Engine triggers.
Digital outputs can be set active or inactive or pulsed with selectable
pulse width and can be controlled on user demand or from a
configured event occurrence.
Discrete I/O control and status is accomplished with the TAIP SS
message.
5.6 Power Management
The CrossCheck GSM can be configured in power-save mode to
prolong vehicle battery life. The power management strategy is
configurable and is in effect only when the vehicle ignition line is not
active, that is, when ignition is on, the CrossCheck GSM is also on.
5-8 CrossCheck GSM Operation Manual
IQEvent Engine Overview
Power management can be configured for timed shutdown/wakeup
cycles (for example, wake up every hour at 50 minutes past the hour,
and stay awake for 10 minutes) and/or for wakeup from an external
signal (for example, when discrete input 1 becomes active).
Configurable shutdown delays allow orderly shutdown (for example,
the Comms Activity Timeout specifies the time to wait for completion
of an active call before shutdown).
Power Management controlled shutdown normally turns off all
CrossCheck GSM components. However, a Comms Standby mode
can be selected to allow the unit to shut down while keeping the GSM
module powered on. The GSM module can then maintain network
status and wake up the CrossCheck GSM on an incoming Ring. When
Comms Standby is selected, the GSM module will remain On for the
selected standby time following each controlled shutdown.
Power Management is configured via the TAIP PM message.
5.7 Password Protection
Access to IQEE configuration and status data can be password-
protected. Each CrossCheck GSM can have its own password, or a
common fleet password can be assigned. When the password is set
and password protection is enabled, the password must be sent each
time a dialog is initiated via Communications Channel or MDT
connection. Autonomous reports generated by the IQEvent Engine
are not affected by password protection.
Passwords are configured and sent via the TAIP PW message.
CrossCheck GSM Operation Manual 6-1
6 Troubleshooting
The CrossCheck GSM is designed to operate in the conditions found
in vehicle applications. When installed and maintained properly, the
CrossCheck GSM mobile unit provides years of trouble-free service.
Invalid inputs at any input port (MDT, GSM, over-the-air) do not
cause permanent loss of function of the CrossCheck GSM. When
presented with inputs that exceed the scope of the appropriate
specification, the CrossCheck GSM will ignore the input or
implement predictable and reasonable behaviors.
The CrossCheck GSM utilizes watchdog timers on applicable tasks to
reduce the possibility of processor “hangs.” When a fatal error is
detected (or a watchdog timer expires) the controller will restart and
attempt to resume normal operation.
All fatal errors and unexpected restarts are logged, and can be
inspected via the MDT port or over the air. (For more information, see
the Extended Diagnostic Message 5 (X5) in the TAIP/IQEvent Engine
Reference Manual.
The CrossCheck GSM mobile unit has no user-serviceable parts. If a
component fails, the CrossCheck GSM must be returned for repair to
the authorized Service and Repair Center.
Should the CrossCheck GSM fail to operate properly, the installer or
service technician should troubleshoot the installation before
returning any components for repair. This chapter provides some
guidelines for troubleshooting common problems associated with the
CrossCheck GSM’s operation. Potential operating problems might
include:
•No power
6-2 CrossCheck GSM Operation Manual
Troubleshooting
•Poor GPS reception
•Poor GSM coverage
•Communication failure with base
•LED error indicators
•IQEvent Engine programming error
If the CrossCheck GSM mobile unit continues to operate poorly after
following the troubleshooting guidelines described in this chapter,
contact the CrossCheck GSM supplier for assistance.
This chapter also describes the self tests available with your
CrossCheck GSM.
6.1 No Power
The GPS and GSM LEDs on the front of the CrossCheck GSM should
be illuminated if there is power to the unit. If both of these LEDs are
off, it is likely that you do not have power to the unit. To correct this
condition, check the conditions described in following sections.
6.1.1 Cabling Problems
Make sure the all cables are securely plugged into the proper unit
connectors. Check for shorts and opens. Verify that you have proper
pin and lug crimps.
6.1.2 Connection Problems
Make sure that all connectors are secure and that the power source is
providing the correct voltage. Verify that crimps are done correctly.
CrossCheck GSM Operation Manual 6-3
Troubleshooting
6.1.3 Fuse Problems
Verify the integrity of the CrossCheck GSM 2-amp fuse (part of the
power cable—P/N 40358). If you do not use the Trimble power cable,
you are responsible for proper fusing of the CrossCheck GSM.
6.1.4 Battery Problems
Make sure your battery power source is generating sufficient current
to power your CrossCheck GSM (1.5A max at 12VDC without the
Voice Upgrade Kit, 2.0A max at 12VDC with the Voice Upgrade Kit).
Check BTU settings for possible problems. Check the under voltage/
over voltage programmed range.
6.2 GPS Reception Problems
The green GPS LED normally remains on when the GPS receiver is
computing position fixes and blinks once, every second, when not
computing position fixes.
If the LED is always off, check the power connections.
If the LED fails to turn on when the vehicle is not obscured from
receiving satellite signals, check the conditions described in following
sections.
6.2.1 GPS Antenna Location
The GPS antenna must be installed in a horizontal plane with a clear
view of the horizon and sky. If a significant portion of the horizon is
blocked by something on the vehicle, try another location on the
vehicle if the current location is suspect. For example, if the GPS
signals are blocked by the air conditioning unit on a vehicle’s cab or
the trailer connected to a tractor, the GPS receiver may have difficulty
acquiring enough satellites for a position fix. Move the antenna to a
new location where it is not blocked.
6-4 CrossCheck GSM Operation Manual
Troubleshooting
6.2.2 Jamming
The GPS antenna should be installed as far away as possible from
transmitting antennas, including satellite communication, radar, VHF
and cellular. These transmitters may emit jamming signals which
interfere with the GPS receiver’s ability to track GPS satellite signals,
which are very weak. Generally, the stronger the other transmitting
device, the wider the distance required between antennas. For the
CrossCheck GSM, Trimble recommends a minimum clearance of 46
centimeters (or approximately 18 in.) between the GPS and GSM
antennas.
Land-based transmitters, including microwave and television
transmitters, can also interfere with GPS reception. If the vehicle is
operating near an antenna farm, the CrossCheck GSM may
temporarily lose GPS reception while the vehicle is in the vicinity of
the transmitters. Reception should return once the vehicle moves
away from the transmitters.
If your GPS signals are being jammed, and moving does not correct
the situation, the source of the jamming signal may be another
antenna mounted too close to your GPS antenna. If possible, turn off
the equipment using other nearby antennas to see if this corrects the
problem. If turning off nearby equipment unjams your GPS signals,
you need to relocate one or more antennas.
6.2.3 Antenna Cable and Connectors
A common problem is damage to the GPS antenna cable during
installation. Inspect the GPS antenna cable along its entire length.
Look for cuts or pinches in the cable or other signs of deterioration.
Check the connectors for signs of stress and broken or bent center
pins. If the cable is suspect, try a known good replacement cable.
If you are using a cable from a source other than Trimble, ensure that
its performance specifications meet those specified in Appendix A.
Cables that do not meet those specifications inhibit the GPS receiver’s
ability to track weak satellite signals.
CrossCheck GSM Operation Manual 6-5
Troubleshooting
6.2.4 Defective GPS Antenna
Infrequently, the GPS antenna may be defective. If the installed GPS
antenna is suspect, disconnect the suspect antenna from the
CrossCheck GSM and temporarily connect a known good antenna.
If the reception significantly improves, replace the defective unit and
return it to Trimble for evaluation and repair.
If you are using an antenna from a source other than Trimble, assure
that its performance specifications meet those specified in
Appendix A. Antennas that do not conform to those specifications,
will inhibit the GPS receiver’s ability to track weak satellite signals.
6.3 Poor GSM Coverage
If the amber GSM LED blinks once every second, even when the
vehicle is in an area with strong GSM coverage, check the conditions
described in following sections. Also, try a known good antenna.
6.3.1 GSM Antenna Location
The GSM whip antenna should be installed in a vertical orientation
with a relatively unobstructed clearance around the antenna. Try
another location on the vehicle if the current location is suspect. Try
another known good antenna.
Even in areas with strong GSM service, there may be pockets where
GSM service is poor or non-existent due to how the carrier builds
their networks. Contact your local service provider for information on
GSM coverage.
6-6 CrossCheck GSM Operation Manual
Troubleshooting
6.3.2 GSM Jamming
The GSM antenna should be installed as far away as possible from
other transmitting antennas including satellite communication, radar,
and VHF radio. These transmitters may emit jamming signals which
interfere with the GSM phone’s ability to track the GSM signal.
If there are other transmitting antennas located on the vehicle, try
moving the GSM antenna farther away from these antennas.
Generally, the stronger the other transmitting device, the wider the
distance required between antennas.
6.3.3 Antenna Cable and Connectors
A common problem is damage to the GSM antenna cable during
installation. Inspect the antenna cable along its entire length. Look for
cuts or pinches in the cable or other signs of deterioration. Check the
connectors for signs of stress or corrosion and broken or bent center
pins. If the cable is suspect, try a known good replacement cable.
CrossCheck GSM Operation Manual 6-7
Troubleshooting
6.3.4 Defective GSM Antenna
Infrequently, a new GSM antenna could be defective or could become
defective because it is prone to vandalism and other sources of
mechanical damage. Inspect the antenna.
If there are signs of damage, disconnect the antenna and temporarily
connect a known good antenna.
If the GSM service significantly improves, replace the defective
antenna.
If you are using an antenna from a source other than Trimble, assure
that its performance specifications meet those specified in
Appendix A. Antennas that do not conform to those specifications,
will inhibit the transceiver’s ability to receive and transmit.
6.4 No Data Communication with Base
Check the conditions described in following sections if the
CrossCheck GSM cannot communicate with the base, you can see
that it is calling in data mode, and you have verified that it is calling
the correct number.
6.4.1 Base Modem Configuration
Consult the modem manual for configuration instructions. Each
modem manufacturer has its own settings and control commands.
Verify that your configuration, PIN numbers, etc. are correct.
6.4.2 Defective CrossCheck GSM Unit
In this case, the only remedy is to replace the CrossCheck GSM and
return the defective unit to Trimble, or a local service center, for
repair. Before returning the CrossCheck GSM, be sure to save the
CrossCheck GSM’s configuration settings, and remove your SIM.
6-8 CrossCheck GSM Operation Manual
Troubleshooting
If you believe that the CrossCheck GSM is defective, first move into
an area with strong GSM coverage. Call the CrossCheck GSM from a
regular phone. Be sure to use the data number for the SIM, not a voice
number. Try a known good GSM antenna.
If you hear tone when the CrossCheck GSM answers, then the
CrossCheck GSM is operating normally. If you do not receive a signal
tone, the CrossCheck GSM may be defective.
6.4.3 No Modem Connection with Base Station
Confirm that the base station modem is configured correctly, and
CrossCheck GSM unit is configured and operating correctly. Check to
see if the proper base station phone number is programmed correctly.
Confirm the following:
•Verify the base station software is calling the correct
CrossCheck GSM telephone number. Often SIMs have both
voice and data numbers. Confirm that the base is calling a data
number.
•If you are using SMS, make sure the correct SCA is set.
6.4.4 Base Station Software
FleetVision
If you are using FleetVision:
•Check channel setup for proper settings.
•Verify that the CrossCheck GSM unit is programmed correctly.
•Check system for proper modem setup.
CrossCheck GSM Operation Manual 6-9
Troubleshooting
Other Tracking Software
If the base station is not using FleetVision software, the base station
software may not be correctly integrated with the CrossCheck GSM.
Contact your software vendor for assistance.
6.5 Updating Firmware in the Field
You can upload new firmware from a PC or laptop connected to the
MDT port.
For more information on updating firmware in the field, refer to the
Trimble website (http://www.trimble.com/products/catalog/mobile/
xcheckgsm.htm) and follow the re-flash instructions.
6.6 LED Diagnostic Errors
The LED indicators are useful for diagnosing problems. The
CrossCheck GSM mobile unit should be inspected by qualified
service personnel if any of the situations described in Table 6-1
occurs.
6-10 CrossCheck GSM Operation Manual
Troubleshooting
6.7 Understanding Power-up Tests
A series of basic hardware tests are run on power-up to detect fatal
hardware errors. Flaws detected at this level, in most cases, will
prevent the CrossCheck GSM from functioning normally.
6.7.1 Power-up Self-Test
Power-up self-test is initiated automatically on power-up following
the startup initialization code. The controller outputs a prompt to the
Table 6-1 LED Diagnostic Indicators

MDT port. If an ESC is detected at the MDT port within a few
seconds after displaying the prompt, the controller will then issue
status messages via the MDT port, which can be displayed or printed
by a diagnostic terminal (for example, a PC).
The status message will indicate if the unit is working or not. If your
CrossCheck GSM does not pass the power-up Self Test, gather the
status message information and contact your service representative for
help.
If the CrossCheck GSM suffers a fatal error during start up (for
example, memory failure) both LEDs blink at a faster than normal
rate. These errors are occasionally caused by noise or power-supply
transients that exceed specified ratings. If the CrossCheck GSM fails
the power-up Self Test when installed but not on (for example) a test
bench, examine the power supplied to the unit in the vehicle for
excessive noise or fluctuations.
If you still have problems with your CrossCheck GSM, please send
E-mail to Trimble (at Trimble_Support@Trimble.com) with a
description of the problem. Please include all the details you can, such
as the name of the product, serial number, part numbers, firmware
version, LED states, and the like.

C TSIP Implementation
The CrossCheck GSM supports the Trimble Standard Interface
Protocol (TSIP) through the MDT/Aux port. Detailed information
about TSIP and TSIP command and report packets is provided in the
TSIP Reference, Trimble P/N 34462-00.
TSIP is only supported through the CrossCheck GSM’s MDT/Aux
serial port and should be used by advanced users only. As a binary
protocol, TSIP is designed for computer-to-computer interaction.
Note – The CrossCheck GSM supports a battery-backed
configuration block. All user-defined GPS operating parameter
settings and flag settings are stored in the configuration block. Soft
resets (Command Packet 0x25) and powering the unit Off and On do
not effect the settings stored in the configuration block. The contents
of the configuration block can be requested by sending Command
Packet 0x8E 0x6F, and the CrossCheck GSM responds by sending
the configuration block in Report Packet 0x8F 0x6F. For more
information, refer to the TSIP Reference.

The CrossCheck GSM mobile unit can output a selection of
NMEA-0183 Version 2.1 sentences. NMEA-0183 sentences can be
generated and output to the MDT/Aux serial port only, allowing the
CrossCheck GSM to interface with external instruments.
Note – The CrossCheck GSM cannot transmit NMEA-0183 sentences
over-the-air.

NMEA Implementation
Each NMEA sentence includes a sentence ID to distinguish the
sentence from other NMEA sentences in the data stream. The actual
data included in NMEA-0183 sentences is placed in fields. An
NMEA sentence contains several fields, and each field is preceded by
a comma character. The sample sentence in Figure D-1 contains six
fields. NMEA sentences can include an optional checksum value
which is useful for checking the integrity of the data included in the
sentence.
The sentence structure of the sample ZDA sentence, shown below and
the sentence fields are described in Table D-1:
$GPZDA,152145,21,05,1996,-7,00*50
The NMEA-0183 sentence examples in this chapter are presented in
the format shown in Table D-1. The structure of each sample sentence
is shown in the paragraphs preceding the sentence structure table.

Local time zone offset from GMT, 00 to ±13 hours.
(–7 in the sample sentence)
Local time zone offset from, minutes. Fields 5 and 6,
together, yield the total offset. For example, if field 5
is ’–5’ and field 6 is ‘15’, local time is 5 hours and
15 minutes earlier than GMT. (00 in the sample
sentence)
The CrossCheck GSM conforms to NMEA-0183
Version 2.1 which states that checksums are
mandatory for all sentences. Checksum values are
always included in output sentences, but are
optional for input sentences.
D-4 CrossCheck GSM Operation Manual
NMEA Implementation
The numbers in the Field column represent the sentence fields in left-
to-right order. Field 1 is the first field following the first comma
delimiter. In the sample sentence, field 1 contains the UTC Time
value (152145).
D.1.1 Symbols and Delimiters
Symbols and delimiters are used to identify or separate the various
kinds of data included in the sentence.
NMEA-0183 sentences always begin with a dollar sign character ($)
character which is immediately followed by a sentence ID code. For
the sample ZDA sentence, GPZDA is the sentence ID. The dollar sign
character marks the beginning of a sentence.
The string of comma delimited text immediately following the
sentence ID code is composed of fields containing data. Each field
follows a comma character ( , ). For the sample sentence, the data
fields are shown below:
,152145,21,05,1993,-7,00
NMEA-0183 sentences are always terminated with a carriage return
and line feed. The carriage return and line feed pair mark the end of
the sentence.
CrossCheck GSM Operation Manual D-5
NMEA Implementation
D.1.2 Checksum Values
The CrossCheck GSM conforms to NMEA-0183 Version 2.1 which
states that checksums are mandatory for all sentences. Checksum
values are always included in output sentences, but are optional for
input sentences.
The sample sentence, shown in Table D-1, includes a checksum
value. An asterisk character (*) is used to delimit the last data field
from the checksum value (50 in the sample sentence).
The checksum is the 8-bit exclusive OR of all characters in the
sentence, including the commas, between but not including the ‘$’
and ‘*’ delimiters. The hexadecimal result is converted to two ASCII
characters (0-9, A-F). The most significant character appears first.
D.1.3 Field Formats
The data values included in fields meet the format specifications
established for the NMEA-0183 Version 2.1.
Null Fields
Null fields are included in some NMEA sentences when no data is
available for a particular field. Null fields are empty and are usually
reserved for transmitting data on a periodic or irregular basis. The
comma delimiter for the Null field is immediately followed by the
comma delimiter for the next field in the sentence string.
The inclusion of Null fields in a sentence is important because many
NMEA sentences contain a fixed number of fields. NMEA sentence
interpreters (software for processing NMEA sentences) expect to find
a fixed number of fields in these sentences, and specific kinds of data
in each field. The sentence processing software assumes that no data
is available for a particular field when a Null field is encountered
while interpreting a sentence.
D-6 CrossCheck GSM Operation Manual
NMEA Implementation
Latitude and Longitude Values
Latitude and longitude values are included in sentences in
ddmm.mmmm format. Longitude is always represented as
dddmm.mmmm in a single field. Within the field, degree values are in
dd or ddd format, and minutes and decimal fractions of minutes are in
mm.mmmm format.
Latitude and longitude direction values (north, south, east, or west)
are placed in a separate field. Direction is a single character: ‘N’, ‘S’,
‘E’, or ‘W’ for North, South, East, or West.
The datum for latitude and longitude is WGS-84 or NAD-83,
depending on the reference station coordinates. In the U.S.A., the
latitude and longitude coordinates are presented using the NAD-83
datum.
Time Values
Time values are in UTC (Universal Time Coordinated), and are
inserted in sentence strings in hhmmss format, where hh is hours
(from 00–23), mm is minutes, and ss is seconds.
Other Values
The format of data included in each data field is controlled by the
NMEA-0183 Version 2.1 requirements for each type of NMEA
sentence. The NMEA-0183 Version 2.1 standard should be
considered to be the definitive resource for the format and content of
the data fields included in sentences, therefore you should refer to the
standard whenever a question arises about the structure of any NMEA
sentence.

E GSM AT-Commands
CrossCheck GSM supports ETSI 07.07 and 07.05 GSM services by
providing direct access to the internal GSM module. The GSM
interface is enabled by the TAIP MT command (>SMTA<), which
reconfigures the MDT port into AT command mode. Once in AT
command mode, an MDT application has access to most internal
GSM module's functions and features.
To exit AT command mode, the MDT must issue a AT+TAIP
command, which returns the MDT port to TAIP mode. Refer to the
IQEvent Engine/TAIP Reference Manual for details of the transition
to and from GSM-AT mode.
The following is a summary of the AT commands supported by the
CrossCheck GSM, which is a subset of the ETSI 07.07/07.05
command set. Since there is no audio interface at the MDT port, there
is no support for voice calls.

CDMA Code Division Multiple Access. A way to allow many
conversations to occur on the same frequency at the same time.
Each packet on frequency is tagged with a special code so it can be
distinguished from all the other packets. See TDMA.

Administration.
checksum 1) The TAIP message checksum field provides for an optional two-
digit hexadecimal checksum value, which is computed by XOR’ing
all characters from the beginning of the sentence up to and
including the ‘*’ character. If included, the checksum is always the
last element of the sentence before the message ‘<’ delimiter. The
default mode of operation is to include checksum in sentences. The
use of checksums can help in instances where the communication
channel is noisy.
2) The CrossCheck GSM conforms to NMEA-0183 Version 2.1
which states that checksums are mandatory for all NMEA
sentences. Checksum values are always included in output
sentences, but are optional for input sentences.
3) A number of TSIP subpackets use an integer checksum value to
verify the integrity of the data included in a subpacket.

PAD mode Packet Assemble and Disassemble mode is available for two-way
messaging between a base station and a device connected to the
CrossCheck GSM’s MDT/Aux port. In PAD mode, data received
from the MDT/Aux port is assembled into Text (TX) messages that
are then transmitted over the Communications Channel or saved to
the Data Log. Data received in TX messages over the
Communications Channel are extracted from the TX messages and
sent to the device connected to the MDT/Aux port. The
configuration of PAD mode is controlled by the MDT Mode (MT)
message, which allows specification of packet assembly
parameters, including maximum packet length, end-of-packet
delimiters, and packet assembly timeout parameters.
