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 receiv e 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).

Overview

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:

CrossCheck GSM Operation Manual 1-7

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.

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) cov erage. Although originally concei ved
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.

Overview

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 o v ervie w 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.

CrossCheck GSM Operation Manual 1-11

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 interf ace cables,

2-6 CrossCheck GSM Operation Manual

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 scre ws to secure the unit to
the mounting surface. Figure 2-4 shows the mounting
dimensions.

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.

2-8 CrossCheck GSM Operation Manual

Installation

Caution – Use washers sized small enough that they do not tighten
down on the plastic cover of the CrossChec k 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.

CrossCheck GSM Operation Manual 2-9

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.

2-10 CrossCheck GSM Operation Manual

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.

2.5.3 Miniature Magnetic GPS Antenna (P/N 37167)

The Miniature Magnetic Antenna features a magnetic mount for
attaching the unit to ferrous metal surfaces and an integral 5 meter
cable with SMA connector.

Figure 2-11 Miniature Magnetic GPS Antenna

To mount the Magnetic GPS Antenna:

1. Choose the antenna mounting location (see Choosing the GPS
Antenna Mounting Location on page 2-10).

Installation

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.

CrossCheck GSM Operation Manual 2-19

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.

both above and below the antenna mounting surface. This access is
required for installing fasteners and for routing the antenna cable.

Cellular phone dealers and installers are experts on cellular antenna
placement. For some installations, the installer can substitute a glass­mount 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

wraps to secure the cable along its route.

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.

For fixed mount operation, the maximum gain of the antenna must not exceed 7 dBi. For mobile

operation, the maximum gain of the antenna must not exceed 3 dBi. 

WARNING! Use of this unit in portable operations is not permitted.

Each input floats to a logic high state (inactive) when left open.
Grounding an input causes a logic low state (activ e). The CrossCheck
GSM can be configured to detect either logic high or logic low states
at the inputs whenever the unit is powered on.

2-26 CrossCheck GSM Operation Manual

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.

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

close to the battery as possible to ensure that the CrossCheck GSM
is connected to the cleanest source of power possible.

2-32 CrossCheck GSM Operation Manual

Installation

The CrossCheck GSM is protected against both input power over­voltage and reverse polarity. The primary power cable has a built-in 2­amp 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. IQEv ent 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.

CrossCheck GSM Operation Manual 2-33

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 of f, 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.

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.

Configuration

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

CrossCheck GSM Operation Manual 3-5

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

3-6 CrossCheck GSM Operation Manual

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=<

CrossCheck GSM Operation Manual 3-7

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 .gsmw orld.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

T o 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:

3-8 CrossCheck GSM Operation Manual

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 back­off / retry algorithm. For detailed information, refer to Back-of f/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.

Configuration

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.

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 cost­effective data transfer capabilities.

3.5.1 Service Provider Configuration

You need to select a GSM service provider, purchase a SIM, and hav e
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.

4 Operation

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

• GSM Phone

The IQEvent Engine controls the CrossCheck GSM’s operation and
interfaces with both the GPS receiver and GSM phone. For detailed
information, see the TAIP/IQEvent Engine Reference Manual.

CrossCheck GSM Operation Manual 4-1

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 acti v e, 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.

4-4 CrossCheck GSM Operation Manual

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.

5 IQEvent 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

CrossCheck GSM Operation Manual 5-1

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 ev ents, generates ev ent reports, and initiates
other user-specified event actions. Its power comes from its
configurability (event triggers and actions are completely user­specified) and its self-modifying capability (event actions can enable
or modify the current configuration).

5.1.1 Event T riggers

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

5-2 CrossCheck GSM Operation Manual

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

CrossCheck GSM Operation Manual 5-3

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 out­bound message queue. The message queues draw from a single
