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-2x30™ 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-2x30™

• 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™

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-2x30s™. 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-2x30™ are:

• GSM/GPRS

2.2.2 LMU-2x30™

The LMU-2x30™ 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-2x30™

• 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-2x30™ 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-2x30™ is capable of sending and receiving. This

interface allows System Integrators to communicate directly with LMU-2x30’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-2x30™ in a variety of

formats

• Present historic information received from the LMU-2x30™, typically in a

report/chart style format

• Request location updates from one or more LMU-2x30s™

• Update and change the configuration of one or more LMU-2x30s™

2.3 Wireless Data Primer

This section is meant to give an overview of the wireless data technologies employed by the

CalAmp LMU-2x30™.

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

combination. SMS was created as part of the GSM Phase 1 standard.”1

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

mobile contexts.”2

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 LMU-

2x30™ offers quad-band (850/900/1800/1900 MHz) capabilities to support networks

worldwide.

V1.0.10 December 12, 2010

3 Hardware Overview

3.1 Location Messaging Unit-2x30™ (LMU-2x30™)

3.1.1 LMU-2x30™ Handling Precautions

3.1.1.1 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.

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-2x30’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 non-

functional 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.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

3.1.1.4 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.

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-2x30™ GPS Antenna to another

LMU-2x30™ 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-2x30™ GPS Antenna

should be kept at least four inches apart from any active LMU-2x30™ GSM Antenna or any

other active high power RF transmitter with power greater than 1 Watt.

V1.0.10 December 12, 2010

3.1.2 Environmental Specifications

The LMU-2x30™ 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-2x30™ 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.

Configuration and Activation

3.5 Configuration Quick Start Guide

This section details how to quickly get an LMU-2x30™ provisioned and configured to point

at a specific server. It is assumed that a PEG script has already been created and is being

managed through LMU Manager or PULS™, the CalAmp Maintenance System.

We are making three assumptions to simplify the setup process:

• You have created, installed and configured an LM Direct™ Server to receive

messages from the LMU-2x30™. (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 as described in Appendix A and

B respectively

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

3.6 Quick Start - General Config

All LMU-2x30s™ must go through a common step during the configuration and

provisioning process. Specifically, this is pointing the LMU to the 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-2x30™

2. Plug the serial cable into your laptop

3. Open a terminal session to the LMU-2x30™

4. Enter the address of the LM Direct™ server.

AT$APP PARAM 768,0,ddd.ddd.ddd.ddd

AT$APP PARAM 769,0,ppppp

where ddd.ddd.ddd.ddd is the publicly addressable IPV4 address of the server and

ppppp is the UDP port number

The LMU-2x30™ will respond with: OK

5. Alternatively if a URL has been set up it may be programmed with:

AT$APP PARAM 2319,0, “myURL.MyCompany.Com”

Where “myURL.MyCompany.com” is the URL assigned to the server, the LMU-

2x30™ will respond with: OK

Note that if you are not using a URL, this field must be cleared using:

AT$APP PARAM 2319,0, “”

6. Verify your settings by using:

AT$APP INBOUND?

3.7 Auto provisioning of GSM 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)

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).

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

3.8 Activating a GSM LMU using AT Commands

For a GSM/GPRS operator3 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 devices4. 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.

3 Trivia time… GSM is dominant in Europe and networks are run by Operators, not carriers. Carriers, at least in a

European sense, refer to the rats that carried the black plague.

4 It is important to note that the operator may charge more to access certain APNs.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

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 2306,0, “” (for a blank APN)

AT$APP PARAM 2314,0,“myUSername”

AT$APP PARAM 2315,0,“myPassword”

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 PARAM 1285,0,<SIM pin>

You can confirm activation by watching the Comm LED to see if it goes solid. You may

also confirm activation using ATIC A good response should look similar to the following:

GSM Registered: Yes

GPRS Registered: Yes

Connection: Yes

RSSI: -70 dBm

4 Installing the LMU

The installation of the LMU and its antennas can have a major impact on the LMU’s

performance. It is recommended that installers be familiar with the installation of GPS and

cellular devices and are comfortable in a vehicle environment.

4.1 Preparing for Installation

Be sure you have received all the LMU components you need. This must include:

• The LMU to be installed

• A power harness

• GPS Antenna

• Comm Antenna

• Optional Components:

o Input and output cables

o Relays

o Host serial devices (e.g. PDAs, laptops, other serial devices)

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.2 Plan The Installation

Verify Power, Ground and Ignition. Be sure to check each source (power, ground and

ignition) to ensure that the proper signaling exists. This is typically accomplished with a

multi-meter.

Before drilling any holes or running any wires, decide where each hardware component will

be located (LMU, antennas, peripherals, etc.). Be sure that the cables to the LMU are not

bent or constricted in any way. Also make sure that the LMU is kept free from direct

exposure to the elements (sun, heat, rain, moisture etc...).

Be advised that an installation that violates the environmental specifications of the LMU will

void the warranty.

The best way to ensure a trouble-free installation is to consider your options and make some

decisions before you start. Take a look at the vehicle and determine how to best install the

LMU for the following purposes:

• Accurate data gathering and simulation of how customers actually use your solution

• Ongoing monitoring and maintenance of LMU equipment

• Accidental or intentional alteration of the equipment or cable connections

The following sections cover some of the issues to consider when planning your LMU

installation.

4.2.1 Size and Placement of LMU Unit

The dimensions of the LMU should be taken into account, particularly when installing in a

vehicle:

Whether you intend to place the LMU under a seat or into a cavity behind the vehicle’s

interior molded trim, be sure the LMU will fit before drilling any holes or running cable

• Be certain that the cables running to the LMU will not be bent or constricted.

Damage to the cables may impede the LMU’s performance.

• Be certain that the installation point will not violate any of the LMU’s environmental

specification (temperature, moisture, etc…) as improper installation of the LMU may

void the warranty.

See the LMU Environmental Specifications for the exact measurements and specifications of

the LMU-2x30™.

Typical installations will place the LMU under the vehicle dash board, or in the trunk. Make

sure you can get access to the unit afterwards as under some circumstances it may be

necessary to add additional wiring or connections to the LMU.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.2.2 Placement of Antennas

There are effectively three options for placements of an antenna:

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.2.2.1 Comm Antenna Placement Guidelines

The Comm. Antenna must be located at least 20cm away from vehicle passengers, other

personnel, or bystanders in order to comply with FCC radio frequency exposure limits.

Typically, the Comm antenna used by the LMU for wireless service is a standard 3-dB gain

whip. It mounts with standard mounts (i.e. thru-hole, magnetic mount or peel and stick) and

requires a ground plane to work properly. If possible, it should be located at least 3 feet from

the GPS antenna. Ensure that the cable does not get crushed during installation.

Please note that the antennas provided by CalAmp combine both the GPS and Comm

portions.

4.2.2.2 GPS Antenna Placement Guidelines

In order to maximize the performance of the LMU the GPS antenna should have a clear

view of the sky. When installing the GPS antenna on a vehicle, make sure that there are no

obstructions close to the antenna that might block the view 360° to the horizon. Things like

air horns, lights, vents, etc… should not block the antenna beyond 5° above the horizon.

The best location is usually near the center of the roof; however it is also desirable to locate

the cellular antenna as far from the GPS antenna as is practical.

14 Examples of good and poor GPS antenna placements

The received signal levels at the GPS antenna from the satellites are very low in power

(approximately -136 dBm), so any blockage of the antenna can affect the quality of the

location computed by the receiver. Kinks or tight knots in the antenna cable can also

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

prevent the GPS receiver from operating properly. When laying out the antenna cable, care

should be taken so that the cable is not subjected to crushing or strain.

4.2.2.3 Placement of Combination and Internal Antennas

When dealing with combination antennas, it is more important to considered GPS

performance over Comm performance. GPS signal strengths are much lower than those

typically seen by cellular networks supported by the LMU. In order to maximize the

performance the LMU should have a clear view of the sky as possible. When installing the

GPS antenna in a vehicle, make sure that there are as few obstructions as possible close to

the LMU that might block the view 360° to the horizon. As with stand-alone GPS antennas,

nothing should not block the combination antenna beyond 5° above the horizon with the

best location being near the center of the roof. For more covert installs, directly under the

front or rear-windshields are also acceptable.

16 Examples OK(Yellow) and Poor(Red) internal antenna placements

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.2.3 Access to the SIM (Subscriber Identity Module) Card

When used in a GSM or iDEN network, each LMU uses a Subscriber Identity Module (SIM)

card, which should be inserted before you install the LMU for the first time. The SIM card is

attached to the main-board inside the housing of the LMU unit.

At some future time, you might need or want to replace the SIM card with a different one,

so try to install the LMU in such a way that the cover can be removed to make the SIM card

accessible.

4.2.4 Protection from Heat

It is best not to place the LMU unit in an unusually warm location such as directly near

heater vents, near hot engine components or in direct sunlight. The maximum temperature

that can be tolerated by the LMU is described in the LMU Environmental Specifications

section.

4.2.5 Visibility of Diagnostic LEDs

Status LED lights on the front of the LMU unit can provide valuable information about the

operation of the LMU. When feasible, attempt to install the LMU in such a way that these

lights can be seen with reasonable ease.

You may find it useful to be able to view the LEDs periodically to make sure that the LMU

is operating properly. If at any time you should encounter a problem with the LMU, you

may need to read the LEDs in order to troubleshoot the problem. If you cannot fix the

LMU yourself, you will need to provide the LED information to CalAmp customer support.

For information about how to interpret the LEDs, see the Status LED Behavior section.

4.2.6 Cable Length

The RF cables which are provided for connecting to the LMU antennas should be used at

the length provided. Do not cut cables. Instead, coil any excess cable length, making sure not

to crimp or flatten the antenna cable.

4.2.7 Moisture and Weather Protection

The LMU unit must be located where it will not be exposed to moisture or water. In a

typical installation inside a vehicle this is not commonly thought to be a concern; however, it

might be best to avoid locating the LMU below a car’s cup holders, or where rain might

easily splash into the compartment when a door is opened.

4.2.8 Preventing Accidental or Unauthorized Modification

If you anticipate that fleet drivers or others might interfere with the LMUs once they are

installed, take steps to be sure that it is not easy to disconnect the antenna wiring, remove

the LMU from its power source, etc.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

Two common methods are the use of Tamper Proof Sealant or creation of PEG Script to

detect power loss or GPS antenna disconnections.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.3 Installing the LMU in a Vehicle

This section provides instructions for installing an LMU in a vehicle.

Be sure to consider the design decisions described in the previous sections. When you are

ready to begin installing the LMU, follow these steps:

4.3.1 Place the LMU unit in the vehicle.

Typically, the LMU should be placed under the passenger seat or dashboard of the vehicle.

LMUs with internal antennas should be placed to maximize their GPS performance. A

typical location include under the dash close to the front wind-shield.

Attach the LMU to the solid body of the vehicle, not to plastic panels. The LMU can be

placed out of sight by removing interior trim and molding to expose available space, then

replacing the trim once the LMU is in place.

4.3.2 Connect power, ignition, and ground.

The power input (red wire) must be connected to a constant (un-switched) +12 VDC or

+24 VDC supply; preferably, connected directly to the vehicle battery terminal or as close to

it as possible. This connection point should be fuse protected to not more than 5 Amps.

The ignition input (white wire) must be connected to the vehicle ignition or another

appropriate key operated line, such as ACCESSORY, ensuring that power to the ignition

wire is available only when the vehicle ignition is on.

The ground line (black wire) must be connected to chassis ground.

Failure to connect these lines in the manner described may result in discharge of the vehicle

battery.

For best results, it is strongly recommended that the LMU connection be on its own circuit.

Connect the power input directly to the vehicle battery if possible and protect the circuit

with an inline fuse. If you must connect through the fuse box, use standard commercial

wiring practices to create a permanent installation rather than using press-in fuse clips or

other temporary measures.

DO NOT connect the power cable to the LMU at this time.

4.3.3 Place the GPS antenna.

The GPS antenna must have a clear view of the sky. Mount the GPS antenna on the

vehicle’s highest point (for example, the roof of a car). Make sure that there are no

obstructions close to the antenna that might block the view 360° to the horizon. Air horns

lights, vents, etc.. should not block the antenna beyond 5° above the horizon.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

Kinks or knots in the antenna cable can prevent the GPS receiver from operating properly.

When laying out the antenna cable, take care that the cable is not subjected to crushing or

strain.

The ideal location is typically near the center of the vehicle’s roof. However, it is also

desirable to locate the cellular antenna as far from the GPS antenna as possible.

Figure 17 - GPS Antenna Location

4.3.4 Mount the Comm. Antenna.

When using separate Comm and GPS antennas, it is best to locate the Comm. Antenna at

least 3 feet from the GPS antenna. Ensure that the cable is not crushed during installation or

normal vehicle operation.

Again, the Comm. Antenna must be located at least 20cm away from vehicle passengers,

other personnel, or bystanders in order to comply with FCC radio frequency exposure limits.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.4.1 Ignition and Inputs

The LMU-2x30™ provides up to 5 external inputs and one internal. The external inputs are

protected from typical vehicle transients and can be directly connected to most vehicle level

logical inputs from 4 volts up to the vehicle power input level (typically 12 VDC). Their

input impedance is approximately 10kΩ. One of these inputs is dedicated to sensing the

vehicle’s ignition status to provide for flexible power management. The other two inputs

may be used to sense vehicle inputs such as cooling unit operation, a hidden driver “Panic”

switch, taxi on-duty/off-duty meter status or many others.

The ignition input is pulled to ground through the 10k resistance, where the other inputs can

either be normally High (i.e. pulled to +12v through a 10k resistor) or Low (i.e. pulled to

ground through a 10k resistor). Input 1 is always biased low, inputs, 2-4 are biased high The

diagrams below show how to connect the inputs in both a high- and low-biased

configuration:

Figure 21 - Sample Input Wiring

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.4.2 3-Axis Accelerometer Input

The LMU-2x30™ 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.

4.4.3 Outputs

The LMU’s outputs are designed to drive external relays. These outputs provide a high-

current, open-collector driver that can sink up to 150 mA each. These drivers may be used to

drive external relays that can then control vehicle functions such as door locks, fuel shut-off

valves, sirens and lights. If additional current is required to drive the relays, external circuitry

can be added to source the current. This diagram is a typical use of an output to drive a relay.

V1.0.10 December 12, 2010

4.5 Installation Verification

In many cases it is desirable to verify that an installed LMU-2x30™ is working properly.

That is, installers should verify that the GPS and communications functions of the LMU-

2x30™ are working properly before departing the installation site. In more robust cases,

some key configuration settings such as the Inbound Address and URL should also be

verified.

Note that these processes are all based on issuing AT Commands to the LMU-2x30™. It is

expected that installers will have access to a serial port expansion cable and a laptop or PDA

capable of a terminal connection. Alternatively, an SMS message can be sent to an LMU-

2x30™ to obtain its current status.

4.5.1 Comm Verification

Installers should first verify that the LMU-2x30™ has been acquired and has registered to

the wireless network. This may be verified in one of two ways. First, installers may look at

the Comm LED (i.e., the one closest to the SMC antenna connector). If this LED is solid,

then the LMU has registered to the network and established a data session.

If the LED is not visible, then Comm may be verified using an AT Command:

AT$APP COMM?

Depending on the wireless network being used, one of the following responses should

appear:

GSM RSSI:-69 Comm

If any of the responses return Not-Acquired or Not-Registered, the wireless

network operator should be contacted for further troubleshooting.

Please note that it may take several seconds for the LMU-2x30™ to communicate with the

modem and acquire the wireless network.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.5.2 GPS Verification

The next step is to verify that the GPS receiver is seeing enough satellites to obtain a valid

GPS position. Again, installers have two choices on how to perform this verification. First,

like the Comm Verification, there is a GPS status LED (i.e., the one closest to the SMA

connector). If this LED is solid, then the LMU has found GPS service.

If the LED is not visible then GPS service may be verified using an AT Command:

AT$APP GPS?

The response should be similar to:

Lat=3304713, Lon=-11727730, Alt=0

Hdg=113 Spd=0 3D-RTIME HDOP=130 nSats=7

Installers are looking for the 3D-RTIME setting along with a valid Lat, Long pair (i.e.

something other than 0). If the GPS receiver does not have a valid lock within 2-3 minutes,

installers should check antenna placement (see the Installation Notes section for placement

suggestions), the antenna connector and that the antenna has a clear view of the sky. For

further troubleshooting, installers should contact CalAmp Support

(M2MSupport@CalAmp.com)

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.5.3 Inbound Verification

The last item to verify is that the LMU-2x30™ is sending data to the correct server. In

general, this is a two-step process that will need the aid of an observer on the back end. That

is, a technician will have to be logged in so they can monitor data coming into the backend

mapping/vehicle management application.

First, verify that the LMU-2x30™ is using the correct Inbound IP address by using:

AT$APP INBOUND?

The response should be similar to:

INBOUND LMD

INBOUND 0 ADDR ddd.ddd.ddd.ddd:ppppp *

INBOUND 0 URL myURL.myCompany.com

INBOUND 1 ADDR 0.0.0.0:20500

INBOUND 1 URL

INBOUND 2 ADDR 0.0.0.0:20500

INBOUND 3 ADDR 0.0.0.0:20500

The installer will need to verify with a backend technician that the, URL

(myURL.myCompany.com ), IP address (ddd.ddd.ddd.ddd) and port (<ppppp>) are correct.

The second step is to verify that the LMU-2x30™ is sending data. The best way to do this is

to force the LMU-2x30™ to send in an unacknowledged Event Report (i.e., its current GPS

location) with the following command:

AT$APP PEG SUNRPT 255

The LMU-2x30™ will respond with: OK

The backend monitor must then be contacted to confirm that they received an Event Report

with Event Code 255.

Assuming that all three sections have passed, the installation can be considered to be

complete.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

4.5.4 Verification via SMS

The current Comm, GPS and Inbound status of a GSM LMU can be obtained via SMS

provided you have access to an SMS capable phone or PDA.

Using your handset, send the following SMS Message to the LMU:

!R0

Within a few minutes, the LMU should return a response in the following format:

APP: <App ID> <Firmware Version>

COM:<RSSI> [./d/D][./a/A][./L][IP address] [<APN>]

GPS:[Antenna <Short/Open/Off>] | [No Time Sync] |

[<FixStatus> <Sat Count>]

INP:<inputs states> <vehicle voltage>

MID:<mobile ID> <mobile ID type>

INB:<inbound IP address>:<inbound port> <Inbound

Protocol (LMD/LMX)>

• APP:

o <App ID>:

The Application ID value of the LMU indicating the host platform and the

wireless networking technology of the LMU.

o <Firmware Version>:

The current firmware version in use by the LMU

• COM:

o <RSSI>:

This is the signal strength the wireless modem sees from the network. In

general the LMU is at least scanning for the network if the RSSI is not -113.

o [./d/D]:

If the character ‘D’ is present, it indicates the LMU had a data session

established when it responded to the status request. For the 8-Bit product line

an upper case ‘D’ indicates both the Inbound and Maintenance sockets are

ready. The lower case ‘d’ indicates that only the Maintenance socket is ready.

A ‘.’ indicates no sockets are ready.

o [./a/A]:

This field indicates if the LMU has received an Acknowledgement from the

Inbound server. This field will be empty if the LMU has never received an

ACK.The lower case ‘a’ will be present if it has received an ACK since the last

cold boot (i.e. power cycle) but not the last warm boot (App Restart or Sleep).

The upper case ‘A’ will be present if the LMU has received an ACK since the

last warm boot. A ‘.’ Indicates no acknowledgement has been received.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

o [./L]:

This field indicates if the LMU’s log is currently active. An ‘L’ indicates that

the log is currently in use (i.e. one or more records have been stored) where a

‘.’ indicates the log is inactive.

o [IP Address]:

This is an optional field if and is only present if the LMU has established a

valid data session. This field will contain the current IP address of the LMU as

assigned by the wireless network. Note that if you see a value of 192.168.0.0,

this is an indication that the LMU has not been able to establish a data session.

o [<APN>]

The current Access Point Name in use by a GSM LMU.

• GPS:

o [Antenna <Short/Open/Off>]:

This field, if present, indicates a problem with the LMU’s GPS antenna. A

value of Short indicates that the antenna cable has likely been crushed. A value

of Open indicates that the antenna cable is either cut or disconnected. A value

of Off indicates that the LMU’ GPS receiver is off.

o [No Time Sync]:

If this field is present, it indicates that the LMU’s GPS receiver has not been

able to find even a single GPS satellite. This would likely been seen in

conjunction with the above antenna error, or if the LMU GPS antenna is

otherwise blocked5.

o [<FixStatus> <Sat Count>]:

If these fields are present it indicates that the LMU has, or had a valid GPS

solution. The <Sat Count> field indicates how many GPS satellites are

currently in use by the LMU. The <FixStatus> field indicates the type of fix.

The Fix Status types are detailed in the LM Direct Reference Guide.

• INP:

o <input states>:

This field details the current state of each of the LMU’s discreet inputs. This

field is always 8 characters long. The left most character represents the state of

input 7 where the right most represents the state of input 0 (i.e. the ignition).

A value of 1 indicates the input is currently in the high state. A value of 0

indicates it is currently in the low state.

o <vehicle voltage>:

This field will contain the current reading of the LMU’s internal A/D. This

will be the supply voltage provided to the LMU in mV.

• MID:

o <mobile ID>:

This will be the current mobile ID in use by the LMU.

5 For example you may see this if the vehicle is in a garage when the LMU is powered up.

LMU-2x20™ Hardware and Installation Guide

V1.0.10 December 12, 2010

o <mobile ID type>:

This will be the type of Mobile ID in use by the LMU. The available types are,

Off, ESN, IMEI, IMSI, USER, MIN and IP ADDRESS.

• INB:

o <inbound IP address>:

This is the current IP address in use by the LMU. This value should match the

IP address of your LM Direct™ server.

o <inbound port>:

This is the current UDP port the LMU will use to deliver its LM Direct™

data. This value should match UDP port you are using on your LM Direct™

server. It is typically 20500.

o <Inbound Protocol (LMD/LMX)>:

This is the current UDP/IP messaging protocol in use by the LMU. In general

it should be LMD.
