server, PULS™ scripts, and firmware, can all be updated over-the-air. PULS™ offers out-of-the-box
hands free configuration and automatic post-installation upgrades. You can also monitor unit health
status across your customers' fleets to quickly identify issues before they become expensive problems.

2 - System Overview

2.1 Overview

The entire purpose behind a fleet management system is to be able to remotely contact a vehicle,
determine its location or status, and do something meaningful with that information. This could include
displaying the vehicle location on a map, performing an address look-up, providing real-time driving
directions, updating the vehicles ETA, monitoring vehicle and driver status or dispatching the vehicle to
its next pick up.

These functions, of course, are completely dependent on the capabilities of the vehicle management
application. The role of the CalAmp LMU-3030™ is to deliver the location information when and where
it is needed.

A typical fleet management system based on a CalAmp device includes the following components:

 A wireless data network
 An LMU-3030™
 Host Device (GPS NMEA only)

 An LM Direct™ communications server
 Backend mapping and reporting software which typically includes mapping and fleet reporting

functions

 PULS™
 LMU Manager™

Basic System Architecture

2.2 Component Descriptions

2.2.1 Wireless Data Network

The Wireless Data Network provides the information bridge between the LM Direct™ server and the

LMU-3030™. Wireless data networks can take a variety of forms, such as cellular networks, satellite
systems or local area networks. Contact the CalAmp sales team for the networks available to the LMU­3030™.

2.2.2 LMU-3030™

The LMU-3030™ is responsible for delivering the location and status information when and where it is
needed. Data requests mainly come from the following sources:

 PEG™ script within the LMU-3030™
 A location or status request from the LM Direct™ server
 A location or status request from LMU Manager
 An SMS request made from a mobile device such as a customer’s cell-phone

In some cases, it is necessary to run an application in the vehicle while it is being tracked by the
backend software. Such examples could include instant messaging between vehicles or a central
office, in-vehicle mapping or driving directions, email or database access. In most of these cases you
will be using the LMU-3030™ as a wireless modem as well as a vehicle-location device.

2.2.3 LM Direct™ Server

LM Direct™ is a CalAmp proprietary message interface specification detailing the various messages
and their contents the LMU-3030™ is capable of sending and receiving. This interface allows System
Integrators to communicate directly with LMU-3030's™. Please refer to the LM Direct Reference

Guide for details.

2.2.4 Backend Software

Backend software is a customer provided software application. Regardless of its purpose, one of its
primary functions is to parse and present data obtained from the LM Direct™ server. This allows the
application to do any of the following:

 Display location database on reports received from the LMU-3030™ in a variety of formats
 Present historic information received from the LMU-3030™, typically in a report/chart style format
 Request location updates from one or more LMU-3030s™
 Update and change the configuration of one or more LMU-3030s™

2.2.5 PULS™

PULS™ (Programming, Update and Logistics System) is CalAmp’s web-based maintenance server
offering out-of-the-box hands free configuration and automatic post-installation upgrades. PULS™
provides a means for configuration parameters, PEG scripts, and firmware to be updated Over-The-Air

(OTA) and allows CalAmp customers to monitor unit health status across your customers’ fleets to
quickly identify issues before they become expensive problems.

2.2.6 LMU Manager™

LMU Manager is the primary configuration tool in the CalAmp system. It allows access to almost every
feature available to the LMU-3030™. Unlike the backend software, it has the option of talking directly
to an LMU-3030™ or making a request forwarded by the LM Direct™ server.

For further details on using LMU Manager, please refer to the LMU Manager Users Guide.

3 – Hardware Overview

3.1 Location messaging unit LMU-3030™

3.1.1 LMU-3030™ Handeling Precautions:

Electrostatic Discharge (ESD)

Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two
objects at different electrical potentials caused by direct contact or induced by an electrostatic field.
The term is usually used in the electronics and other industries to describe momentary unwanted
currents that may cause damage to electronic equipment.

ESD Handling Precautions
ESD prevention is based on establishing an Electrostatic Protective Area (EPA). The EPA can be a

small working station or a large manufacturing area. The main principle of an EPA is that there are no
highly charging materials in the vicinity of ESD sensitive electronics, all conductive materials are
grounded, workers are grounded, and charge build-up on ESD sensitive electronics is prevented.
International standards are used to define typical EPA and can be obtained for example from
International Electro-technical Commission (IEC) or American National Standards Institute (ANSI).

This ESD classification of the sub assembly will be defined for the most sensitive component, therefore
the following classifications apply:

 Class 1B – Human Model (< 1 kV)
 Class M1 – Machine Model (< 100V)

When handling the LMU-3030’s™ main-board (i.e. sub assembly) by itself or in a partial housing
proper ESD precautions should be taken. The handler should be in an ESD safe area and be properly
grounded.

GPS Ceramic Patch Handling
When handling the sub assembly it may be natural to pick it up by sides and make contact with the

antenna boards. In an uncontrolled ESD environment contact with the center pin of ceramic patch
antenna can create a path for electrostatic discharge directly to the GPS Module. The GPS Module is
very sensitive to ESD and can be damaged and rendered non-functional at low levels of ESD.

One should avoid contact with the center pin of the patch during handling. The Factory will be placing
a protective layer of Kapton® tape over the patch element to eliminate this ESD path.

Packaging
Anytime the sub assembly is shipped and it is not fully packaged in its final housing it must be sealed

in an ESD safe bag.

Electrical Over-Stress (EOS)
The GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input rating.

Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to cause
damage.

Storage and Shipping
One potential source of EOS is proximity of one LMU-3030™ GPS Antenna to another LMU-3030™

GSM Antenna. Should one of the units be in a transmit mode the potential exists for the other unit to
become damaged. Therefore any LMU-3030™ GPS Antenna should be kept at least four inches apart
from any active LMU-3030™ GSM Antenna or any other active high power RF transmitter with power
greater than 1 Watt.

3.1.2 Battery backup devices

Please properly dispose of the battery in any of the CalAmp products that utilize one, do not just throw
used batteries, replaced batteries, or units containing a back-up battery into the trash. Consult your
local waste management facility for proper disposal instructions.

3.1.3 Environmental Specifications

The LMU-3030™ is designed to operate in environments typically encountered by fleet vehicles,
including wide temperature extremes, voltage transients, and potential interference from other vehicle
equipment.

To ensure proper operation in such an environment, the LMU-3030™ was subjected to standard tests
defined by the Society of Automotive Engineers (SAE). The specific tests included temperature, shock,
vibration, and EMI/EMC. These tests were performed by independent labs and documented in a
detailed test report. In accordance with Appendix A of SAE J1113 Part 1, the Unit is considered a
“Functional Status Class B, Performance Region II” system that requires Threat Level 3 Testing.

The following shows the environmental conditions the LMU is designed to operate in and the relevant
SAE tests that were performed. No formal altitude tests were conducted.

the LMU-3030™ supports an internal 3 Axis Precision Accelerometer as one of its discreet inputs. When

the LMU is moved in any direction, the associated input will be in the High state. If the LMU’s

accelerometer does not detect motion, then the input will be in the Low state. No external connections are
required for this functionality to be operational.

3.3.2 Status LEDs

The LMU-3030™ is equipped with three Status LEDs, one for GPS and one for COMM (wireless
network status), and one for VBUS. The LEDs use the following blink patterns to indicate service:
