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-3050™ 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-3050™
▪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-3050™. 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 LMU-
3050™.

2.2.2 LMU-3050™
The LMU-3050™ 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-3050™
▪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-3050™ 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-3050™ is capable of sending and receiving. This interface allows System
Integrators to communicate directly with LMU-3050'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-3050™ in a variety of formats
▪Present historic information received from the LMU-3050™, typically in a report/chart style format
▪Request location updates from one or more LMU-3050s™
▪Update and change the configuration of one or more LMU-3050s™
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-3050™. Unlike the backend software, it has the option of talking directly
to an LMU-3050™ 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-3050™
3.1.1 LMU-3050™ 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-3050’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-3050™ GPS Antenna to another LMU-3050™
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-3050™ GPS Antenna should be kept at least four inches apart
from any active LMU-3050™ 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-3050™ 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-3050™ 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.

4 –Configuration and activation
▪You have created, installed and configured an LM Direct™ Server to receive messages from the
LMU-3050™. (See LM Direct™ Reference Guide for details)
▪You are using the standard wiring harness from CalAmp and the serial port expansion harness.
▪You have created a HyperTerminal or Putty session.
▪You have contacted the CalAmp sales team regarding the network availability of the LMU-
3050™. This device may not be supported for all the carriers or networks listed in this section (CDMA-
Verizon, CDMA-Sprint, HSPA, GSM), for product availability consult the CalAmp sales team.
4.1Quick Start –General config
All LMU-3050s™ must go through a common step during the configuration and provisioning process.
Specifically, this is pointing the LMU to your LM Direct™ server, either via IP or a URL.
This configuration process is accomplished via a series of AT Commands:
1. Power up the LMU-3050™ and connect a serial cable from the LMU to your laptop
2. Open a terminal session to the LMU-3050™
3. Enter the address of the LM Direct™ server:
AT$APP PARAM 2319,0,ddd.ddd.ddd.ddd

AT$APP PARAM 768,0,ddd.ddd.ddd.ddd (32-bit products only)
AT$APP PARAM 769,0,ppppp
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct™ server and
ppppp is the UDP port number.
4. Alternatively if a URL has been set up for your LM Direct™ server, the LMU may be programmed
with:
AT$APP PARAM 2319,0,myURL.MyCompany.Com
Where myURL.MyCompany.com is the URL assigned to the server.
5. Enter ATIC to verify the correct settings are displayed for your Inbound Server.
This configuration process is accomplished via a series of SMS Commands:
1. Power up the LMU-3050™ and your handset
2. From the handset, send an SMS message to the LMU-3050™ phone number:
!RP,2319,0,ddd.ddd.ddd.ddd
!RP,768,0,ddd.ddd.ddd.ddd (32-bit products only)
!RP,769,ppppp
Where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of your LM Direct™ server and
ppppp is the UDP port number
3. Alternatively if a URL has been set up for your LM Direct™ server, the LMU may be programmed
with:
!RP,2319,0,myURL.MyCompany.Com
Where myURL.MyCompany.com is the URL assigned to the server
4. Verify your settings by sending the commands:
!RP?2319,0
!RP?769,0.

4.2 Auto provisioning of GSM or HSPA LMUs
For certain operators, the LMU can auto-populate the APN, username and password settings based
on the Mobile Country Code (MCC) and the Mobile Network Code (MNC) of the SIM. Upon inserting a
new SIM the APN, username and password will switch to the new SIM card's defaults if the MCC and
MNC values change. The current list of supported MCC and MNC combinations are:
▪AT&T –formerly AT&T Wireless or Cingular Blue (MCC 310, MNC 38)
o APN 0: PROXY
o APN 1: PUBLIC

This feature can be disabled by setting Bit 0 of S-Register 155.

AT$APP PARAM 1024,35,1,1
To re-enable auto-provisioning, use:
AT$APP PARAM 1024,35,1,0
Auto-provisioning occurs when the LMU detects a SIM with a new operator ID (i.e. the first 6 digits of
the IMSI) or when Bit 0 of S155 is cleared and the GPRS context is blank (i.e. Parameter 2306,0).
4.3 Activating GSM or HSPA LMU using AT Commands
Check with the CalAmp Sales team for availability of the LMU-3050™ with GSM or HSPA
modems. For a GSM/GPRS operator you will get the LMU in one of two varieties, one with a SIM and
one without.
If you get an LMU without a SIM (which is the typical case) the operator will simply ask for the IMEI of
the LMU. The IMEI (International Mobile Equipment Identifier) is printed on the bottom of the LMU
under the LMU’s ESN. Again, DO NOT give the operator the ESN of the LMU.
The operator will provide you with a SIM for each account activated. If they are especially nice (or you
are especially persistent) they will also give you a list tying the IMSI (International Subscriber Identifier)
of the SIM to the phone number assigned to it. Please note that the operator will likely tie the IMSI (i.e.
the SIM) to a specific IMEI. Making sure the specific SIM matches to the right IMEI isn’t strictly
necessary, but it will keep everyone’s book-keeping a little cleaner. You may also obtain this
information by running a CSV report in PULS (after the devices have connected to the network and
sent in their first ID Report). See the PULS Users Guide for more information.
If you do happen to have a SIM, the operator will ask for the IMSI and ICC-ID (Integrated Circuit Card
Identifier) along with the IMEI of the LMU. Again, in return you should get a list of IMSIs and Phone
Numbers.
The IMEI, IMSI and ICC-ID are all available through the ATI1 command. The IMEI should also be
printed on the bottom of the LMU.
You should also get an APN (Access Point Name) value. The APN is the device on the network that
allows a GPRS device (i.e. the LMU) to get to the internet. They tend to look like a URL, for example:
myAPN.myOperator.com
Operators can offer more than one type of APN and can even set up a custom APN just for your
devices. The rates they charge will vary depending on the APN service you want. Operators may also
request you use a blank APN. With the APN, you should also receive a username and password
combination.

The last item an operator may provide is a SIM PIN. The PIN is effectively a password to the device.
The main difference here is that the PIN will restrict all the capabilities of the GSM device, where the
SPC is used just for configuration.
The activation sequence for a GSM LMU would therefore look as follows:
AT$APP PARAM 2306,0,“myAPN.myOperator.com”
AT$APP PARAM 2306,1,“myAPN.myOperator.com”
AT$APP PARAM 2314,0,“myUSername”
AT$APP PARAM 2315,0,“myPassword”
For a blank APN the following command can be used:
AT$APP PARAM 2306,0,“” (for a blank APN)
Only enter this next command if you have been given a non-zero PIN as any errors may lock you out
of the modem.
AT$APP PIN <SIM pin>
You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm
activation using
AT$APP COMM STATUS?
A good response should look similar to the following:
GSM Registered: Yes
GPRS Registered: Yes
Connection: Yes
RSSI: -70 dBm
BER: 0
Channel: 0
Cell ID: 0
Base Station ID: 0
Local Area Code: 0
Network Code: 38
Country Code: 310
IMEI (Modem S/N): 500167110060440
IMSI (SIM S/N): 310380100521849

Phone Number:
GPRS APN: IP:Public
Quality of Srvc: 1,0,0,3,0,0
GSM Class: B
[edit][top]4.4 Accessing the SIM
The following instructions should be used when attempting to access the SIM in a GSM LMU-3050™.
1. Remove the top plate of the LMU-3050™. The LMU-3050™’s enclosure is held
together by 4 plastic clips. To remove the cover, squeeze the top plate of the LMU near
the VBus header and pull up then repeat this action near the SIM cover.
2. Remove the top-plate to expose the top-side of the LMU-3050™’s main-board.
3. Align the SIM so the contacts are facing up and the notch is facing into the LMU-3050™
4. Inserst the SIM card into the LMU
5. Snap the LMU-3050 cover back in place

6. Insert the SIM into the LMU.
7.
4.5 Activating a CDMA LMU-3050™
Check with the CalAmp Sales team for availability of the LMU-3050™ with CDMA modems. For
CDMA devices, the activation sequence you will use varies from carrier to carrier. Each of the
supported carriers is documented below.
To obtain an account, a CDMA carrier will generally ask for three things, the Manufacturer, the Product
Type and the ESN. Obviously the first two items are answered by “CalAmp LMU”. The last one is a
little misleading. The ESN on the LMU is the CalAmp serial number. The one the operator is interested
in is the MSN-D (which they call the decimal ESN). DO NOT give them the CalAmp ESN (i.e. the top
one on the label). It will only lead to the carrier telling you that the product doesn’t exist and they can’t
activate it for you.
What you should get back will vary from operator to operator; however at very least it will be the MDN
(Mobile Directory Number) and MIN (Mobile Information Number). You should also ask for the SPC
(Service Programming Code) in case it is not 000000. The SPC is effectively a password to the
modem which allows you to program some of the more sensitive items (ex: the MDN and MIN). Please
note that the MIN and MSID can be the same value.
4.5.1 Activating a CDMA LMU-3050™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp LMU-
3050™ will automatically use this system to attempt to self provision. This procedure assumes that the
LMU-3050™ has never been provisioned or activated before.
