over the air. Our web-based maintenance 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.
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-2640™ 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-2640™
Host Device (GPS NMEA only)
An LM Direct™ communications server
Backend mapping and reporting software which typically includes mapping and fleet
The Wireless Data Network provides the information bridge between the LM Direct™
server and the LMU-2640s™. Wireless data networks can take a variety of forms, such as
cellular networks, satellite systems or local area networks. At this point in time, the networks
available to the LMU-2640™ are:
GSM/GPRS
2.2.2 LMU-2640™
The LMU-2640™ is responsible for delivering the location and status information when and
where it is needed. Data requests can come from any of the following sources:
PEG™ script within the LMU-2640™
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-2640™ as a wireless modem as well as a vehiclelocation 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-2640™ is capable of sending and receiving. This
interface allows System Integrators to communicate directly with LMU-2640’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-2640™ in a variety of
formats
Present historic information received from the LMU-2640™, typically in a
report/chart style format
Request location updates from one or more LMU-2640s™
Update and change the configuration of one or more LMU-2640s™
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
TM
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-2640™. Unlike the backend software, it has the
option of talking directly to an LMU-2640™ 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
This section is meant to give an overview of the wireless data technologies employed by the
CalAmp LMU-2640™.
2.3.1 SMS (Short Message Service)
“The Short Message Service (SMS) is the ability to send and receive text messages to and
from mobile telephones. The text can comprise of words or numbers or an alphanumeric
1
combination. SMS was created as part of the GSM Phase 1 standard.”
SMS message are typically text based, though binary messages are possible and can range in
size from 140 characters to 256 characters depending on the network being used.
2.3.2 GPRS (General Packet Radio Service)
“The General Packet Radio Service (GPRS) is a new non-voice value-added service that
allows information to be sent and received across a GSM mobile telephone network. It
supplements today's Circuit Switched Data and Short Message Service. GPRS is NOT
related to GPS (the Global Positioning System), a similar acronym that is often used in
2
mobile contexts.”
GPRS is being deployed in its initial stages in approximately 52 countries around the world.
Keep in mind that GSM frequencies change depending on your geographic location. In
Europe, GSM sits in both the 900Mhz and 1.8GHz bands. In North America it sits in the
1.9GHz and 850 MHz bands. This means, that in order to roam with your GSM/GPRS
mobile between countries, it needs to be able to operate on multiple frequencies. The LMU2640™ offers quad-band (850/900/1800/1900 MHz) capabilities to support networks
worldwide.

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.
3.1.1.2 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-2640’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.
3.1.1.3 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 nonfunctional at low levels of ESD.
One should avoid contact with the center pin of the patch during handling. Going forward
the Factory will be placing a protective layer of Kapton® tape over the patch element to
eliminate this ESD path.
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.
3.1.1.5 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.
3.1.1.6 Storage and Shipping
One potential source of EOS is proximity of one LMU-2640™ GPS Antenna to another
LMU-2640™ 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-2640™ GPS Antenna
should be kept at least four inches apart from any active LMU-2640™ GSM Antenna or any
other active high power RF transmitter with power greater than 1 Watt.
The LMU-2640™ 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-2640™ 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.
