About this Manual

Welcome to the TrimTracTM Pro Locator Technical Manual. This manual is intended for
use by system integrators, service providers and application developers (collectively,
“Resellers”). It is not intended for end-users of the TrimTrac ProE locator. Any end-user
documentation is to be prepared and furnished by the Resellers.

This manual covers the TrimTrac ProE with 2.03.00.000 and later firmware and
operating on 850 MHz, 900 MHz, 1800 MHz and 1900 MHz Global System for
Mobile communication (GSM) networks.

Data and Event Reporting support is by Short Message Service (SMS), General
Packet Radio Service (GPRS), or both. This manual describes how to set up,
configure, install, operate, and troubleshoot the product. Even if you have used
other GSM or Global Positioning System (GPS) products before, Trimble
recommends that you spend some time reading this manual to learn about the
special features of this product. If you are not familiar with GSM or GPS, visit

TrimTrac ProE Locator Technical Manual v2.0e xiii

Minimum Information Required for Technical Assistance

If you or a user reports difficulty with a TrimTrac ProE locator (i.e. no GPS fixes, not
communicating, LED not working, etc.), it is helpful to retrieve directly from the unit all
current configuration settings and the message log. In some cases, a more detailed debug
log file is required to trouble shoot communications related issues.

Please provide the requested information and follow the procedures described below:

1. Unit IMEI number

2. Name of SIM Card Carrier

Using a Provisioning Module

1. Insert the Provisioning Module in the TrimTrac ProE and connect to it via

HyperTerminal.

2. In HyperTerminal under the “Transfer” menu, select “Capture Text” and

name a file to which the data from the TrimTrac ProE will be saved.

3. To retrieve the configuration and message log, do one of the following:

a. In the HyperTerminal window, type the following AT commands in order:

ATI
AT+CTKC?
AT+CTKF?
AT+CTKJ?
AT+CTKG?
AT+CTKK?
AT+CTKP?
AT+CTKX?
AT+CTKY?
AT+CTKZ?
AT+CTKO?

b. Rather than repeatedly typing these commands, they can be typed once

and saved as a text file. Then use the “Send Text File” command under
the HyperTerminal “Transfer” menu to send the text file to the TrimTrac
ProE.

3. Send the resulting file as an email attachment to your Trimble technical support

representative.

TrimTrac ProE Locator Technical Manual v2.0e xiv

Over-the-Air Retrieval

If the TrimTrac ProE or Provisioning Module are not available, but the TrimTrac ProE is
otherwise communicating with the server application:

1. Send the appropriate QUERY_CONFIG messages to the TrimTrac ProE to

retrieve the GPS, Application, Provisioning, Extended Application and VAM­only parameters. (Reminder: Multiple QUERY_CONFIGs can be included
in a single SMS message.)

2. Provide a log of raw messages, including all position, status and query

responses, as actually received from the TrimTrac ProE in either CSV or Text
file format

Additional Debugging Capability

In most cases, providing the information as requested in the preceding sections will
provide enough information to analyze the operation of the TrimTrac ProE; however,
additional information may be required to troubleshoot communications related issues,
particularly when GPRS is being used. As such, the TrimTrac ProE has additional data
logging capabilities that can be used to debug specific communication problems. To
utilize this enhanced debug logging capability, the TrimTrac ProE must be connected to a
Provisioning Module and a PC to which the data will be logged.

1. Insert the Provisioning Module in the TrimTrac ProE and connect to it via

HyperTerminal.

2. In HyperTerminal under the “Transfer” menu, select “Capture Text” and name a

file to which the data from the TrimTrac ProE will be saved.

3. Configure the device to operate in the manner in which the device will be used.

4. Enable the debug logging capability in the in the HyperTerminal window, type

the following AT commands in order

AT+CTDL=9,5,1
AT+CTDL=5,5,1

5. Issue following command to cause device to reboot in special debugging mode:

AT+CTDL

6. This will cause the device to operate in the debugging mode for as long as the

GSM modem remains powered up. If the GSM modem powers off for any
reason, the debugging mode will be disabled and will not be active when the next
time the GSM modem is powered back on. As such, if it is desireable to leave the

TrimTrac ProE Locator Technical Manual v2.0e xv

debug logging mode active for more than one state machine cycle, then the
Anytime Polling mode should be set “2=OnDemand”. In so doing, the GSM
modem will remained powered up continuously and, as a consequence, the debug
logging will remain active. (Note: if Anytime Polling is set “2=OnDemand”, then
either change configuration of the device to power off the GSM modem or cycle
power to de-active the debug logging mode.)

7. Please return the resulting data log file, along with the complete unit

configuration and message log to your Trimble technical representative for
analysis.

since 1.00.00.000 firmware are summarized in Table 1 through Table 5.

CHANGE SUMMARY FROM 1.00.00.0000 TO 1.03.00.000

Schedule Hours Status flag added to Position Reports and Status Messages. If motion
triggered message is logged during after hours, than TriggerType shall be set
“2=Exception Report” and the Scheduled Hours Status flag shall be set “1=After Hours
Motion”
Low voltage cutoff added to prevent over-draining AA alkaline batteries. If battery
voltage drops below cutoff voltage, a new Status Message will be created and logged
with the Battery Level indicated as 999% indicating that a low voltage cutout has
occurred.

If a LPA-based geofence was re-centered while outside GSM coverage, the
device would continuously attempt to transmit a re-centering notice until the
device re-entered GSM coverage. In the meantime, no new position fixes would
be computed.

If LPA mode was not set to “1=Disabled” and the LPA input was used for geofence
enforcement, the device would skip the DELAY State.

All motion triggered messages will have a TriggerType set “2=Exception
Report” if one or more enforced conditions are violated, including Scheduled
Hours, Geofences, Speeding, or priority inputs (HPA, MPA, LPA).
1 Hz GPS enabled before entering FIX state if motion is detected and Motion

Detailed Safety Information

Exposure to Radio Frequency Signals

The TrimTrac ProE is a low power radio transmitter and receiver. When it is ON,
it receives and also sends out radio frequency (RF) signals.

In August 1996, the Federal Communications Commissions (FCC) adopted RF
exposure guidelines with safety levels for hand-held wireless phones. Those
guidelines are consistent with safety standards previously set by both U.S. and
international standards bodies:

ANSI C95.1 (1992)

NCRP Report 86 (1986)

ICNIRP (1996)

Those standards were based on comprehensive and periodic evaluations of the
relevant scientific literature. For example, over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry reviewed
the available body of research to develop the ANSI Standard (C95.1)

The TrimTrac ProE is not designed to be worn on a person’s body; however, for
body worn operation, this device has been tested and meets FCC and ACA/NZS
RF exposure guidelines when used with an accessory that contains no metal and
that positions the unit a minimum of 1.5 cm from the body. Use of other
accessories may not ensure compliance with RF exposure guidelines.

Electronic Devices

Most modern electronic equipment is shielded from RF signals. However, certain
electronic equipment may not be shielded against the RF signals generated by the
TrimTrac ProE.

Pacemakers

The Health Industry Manufacturers Association recommends that a minimum
separation of six (6”) inches be maintained between a handheld wireless phone
and a pacemaker to avoid potential interference with the pacemaker. The
TrimTrac ProE is not intended for handheld use or to be worn on the body.

Persons with pacemakers:

Should ALWAYS keep the TrimTrac ProE more than six (6”) inches (20
cm) from their pacemaker with the device is operational.

Should not carry the TrimTrac ProE on their person

If there is any reason to suspect that interference is taking place, the
TrimTrac ProE Battery Pack, Vehicle Adapter or Control Module should
be removed immediately from the TrimTrac ProE base.

TrimTrac ProE Locator Technical Manual v2.0e 3

Other Medical Devices

If any other personal medical devices are used in the vicinity of a TrimTrac ProE,
consult the manufacturers of the medical devices to determine if they are
adequately shielded from external RF energy. Physicians may be able to assist in
obtaining this information.

Disable operation of the TrimTrac ProE by removing the Battery Pack or Vehicle
Adapter or Control Module in health care facilities when any regulations posted in
these areas prohibit the use of wireless phones or two-way radios. Hospitals and
health care facilities may be using equipment that could be sensitive to external
RF energy.

Vehicles

RF signals may affect improperly installed or inadequately shielded electronic
systems in motor vehicles. Check with the manufacturer or its representative
regarding the vehicle. Also consult the manufacturer of any equipment that has
been added to the vehicle.

Posted Facilities

Disable operation of the TrimTrac ProE by removing the Battery Pack or Vehicle
Adapter or Control Module in any facility where posted notices prohibit the use of
wireless phones or two-way radios.

Aircraft

FCC and FAA regulations prohibit using wireless phones while in the air. Disable
operation of the TrimTrac ProE by removing the Battery Pack or Vehicle Adapter
or Control Module prior to boarding or loading in an aircraft.

Blasting Areas

To avoid interfering with blasting operations, disable operation of the TrimTrac
ProE by removing the Battery Pack or Vehicle Adapter or Control Module when
in a “blasting area” or in areas posted: “Turn off two-way radio”. Obey all signs
and instructions.

Potentially Explosive Atmospheres

Disable operation of the TrimTrac ProE by removing the Battery Pack or Vehicle
Adapter or Control Module prior to entering any area with a potentially explosive
atmosphere and obey all signs and instructions. Sparks in such areas could cause
an explosion or fire resulting in bodily injury or even death.

Areas with a potentially explosive atmosphere are often, but not always marked
clearly. Potential areas may include: fueling areas (such as gasoline stations);
below deck on boats; fuel or chemical transfer or storage facilities; vehicles using
liquefied petroleum gas (such as propane or butane); areas where the air contains
chemicals or particles (such as grain, dust, or metal powders); and any other area
where it would normally be advisable to turn off motor vehicle engines.

TrimTrac ProE Locator Technical Manual v2.0e 4

For Vehicles Equipped with an Air Bag

An air bag inflates with great force. DO NOT place objects, including the
TrimTrac ProE, in the area over the air bag or in the air bag deployment area. If
in-vehicle wireless equipment is improperly installed and the air bag inflates,
serious injury could result.

Specific Absorption Rates (SAR)

THE TRIMTRAC PROE IS NOT DESIGNED TO BE WORN ON A PERSON’S
BODY; HOWEVER, FOR BODY WORN OPERATION, THIS DEVICE HAS
BEEN TESTED AND MEETS FCC AND ACA/NZS RF EXPOSURE
GUIDELINES WHEN USED WITH AN ACCESSORY THAT CONTAINS NO
METAL AND THAT POSITIONS THE UNIT A MINIMUM OF 1.5 CM FROM
THE BODY. USE OF OTHER ACCESSORIES MAY NOT ENSURE

TrimTrac ProE New Features and Capabilities

The TrimTrac ProE locator is a small, lightweight asset-monitoring device that
requires little, if any, installation when used in its battery-powered configuration.
Different hardware and setting options allow the device to be configured to meet a
variety of demanding installation and operational requirements. Motion-based
reporting continues to be an important tool in minimizing power consumption and
recurring communication costs.

Key Features:

 Portable, AA Battery-Powered

 No External Wires or Antennas Needed

 Low or No Installation Costs

 No Custom Programming Required

 Ready-to-Use Water-Resistant Housing

 Quad-band GSM/SMS/GPRS

 Enhanced GPS

Ready-to-Use, No Custom Programming Required

Simply insert an activated SIM card and batteries and tell the device where to
send the position data and the TrimTrac ProE is ready to start reporting. In its
default configuration, reports are sent nominally at 15-minute intervals whenever
there is motion; status messages are sent once every 12 hours when the device is
at rest. Upon powering up, the device will self-initialize anywhere in the world
and start transmitting if an authorized GSM network is available.

Alternately, the unit can be easily re-configured to address any number of more
sophisticated applications or, when used with an optional plug-in module, be
connected to external power, monitor multiple inputs and control other systems or
devices, such as door locks, immobilizers and remote start systems.

While a basic understanding of the different TrimTrac ProE operational states is
helpful, configuring the TrimTrac ProE does not require a highly skilled software
programmer or technician.

TrimTrac ProE Locator Technical Manual v2.0e 7

Cost-effective, Universally Available Communications

The TrimTrac ProE takes advantage of the near universal availability of GSM
SMS text messaging while also leveraging cost-effective GPRS data rate plans.
Typical SMS plans offer very extensive inter-network roaming capabilities, both
within a host country and internationally. SMS plans also tend to be too pricey
for applications requiring more than a few reports per day.

GPRS data plans, on the other hand, typically allow for lower recurring
communication costs although GPRS coverage and roaming can be restricted in
some areas. The TrimTrac ProE takes advantage of both technologies by
automatically selecting GPRS wherever such service is available, while relying
upon SMS text messages as backup when outside GPRS coverage. This helps
minimize recurring communication costs while allowing the greatest coverage
possible.

Hardware Options

A number of different hardware options are available to enhance the suitability of
the TrimTrac ProE to particular application requirements. These options include
a miniature external GPS antenna that allows for more discrete, protected
installation of the TrimTrac ProE.

In addition, two plug-in modules are offered; both provide connection to external
9-32 VDC power to eliminate the need to change batteries and can monitor inputs
of three different priority levels. The control module also provides two outputs
that can be used to control other on-board devices or systems, such as door locks,
immobilizers and remote start systems.

To address different mounting requirements, two mounting brackets are offered.
A metal bracket is available for more permanent installations while a “quick­release” style plastic bracket is used when rapid insertion and removal of the
TrimTrac ProE is desired. This is particularly useful when a battery- powered
TrimTrac ProE is routinely moved from one asset to another.

Optional Plug-In Modules

The following options are available as plug-in modules that replace the standard
TrimTrac ProE batteries:

Provisioning Module. Allows configuration of the TrimTrac ProE via a
USB 2.0 connection to a PC.

Enhanced Functional Capabilities

Position reporting triggered by motion continues to be an important attribute of
the TrimTrac ProE; however, a range of powerful new functional enhancements
now augments this basic capability. The TrimTrac ProE is backwards compatible
with applications developed for the first generation TrimTrac.

On-board Geofencing

The TrimTrac ProE can self-monitor up to two geofences. These geofences can
be either rectangular or circular with reporting based upon whether the device is
inside or outside the geofence area or when it has simply crossed the geofence
boundary. Geofences can be established either during initial activation of the
device, established on-the-fly via over-the-air commands or upon operation of a
local switch connected to the TrimTrac ProE input module. These capabilities
allow the device to be “locked down” where needed without creating nuisance
reports during normal operation. (See AT+CTKK on page 123)

Scheduled Hours Mode

The feature is particularly useful when monitoring commercial assets that are
used during certain hours of the day, but then are supposed to remain at rest or
within a relatively constrained area during after hours.

The Scheduled Hours Mode feature is used to establish how the device reports
motion or during what time periods a geofence is enforced. During normal hours
of operation, position reports may not be needed unless, for instance, a geofence
has been violated. Outside normal hours of operation, however, any motion of an
asset may be considered “unauthorized” and it would be desirable for the
TrimTrac ProE to report this motion and its current position. Monitoring of
equipment at a construction site is an application example that would use this
Scheduled Hours feature, possibly in conjunction with a geofence. (See
AT+CTKZ on page 134; SET_EXT2_APP_CONFIG on page 152)

Runtime Meters (2)

Equipment maintenance schedules are often managed based upon accumulated
run-time hours. The TrimTrac ProE offers two resetable runtime meters: one is
triggered by motion and, if a plug-in module is used, the other can be hardwired
to contacts on a sensor, such as an oil pressure switch. (See AT+CTKZ on page
134; SET_EXT2_APP_CONFIG on page 152)

Start/Stop Reporting Mode

There are two Start/Stop Reporting modes available under the Report Delay Flag
settings. Alternately, the Motion Report Flag can be used in combination with the
