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 look­up, providing real­time 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 LMU­42x0™ 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 LMU­42x0™
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™

42x0™. 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 LMU­42x0™.
2.2.2 LMU­42x0™
The LMU­42x0™ 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 LMU­42x0™
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 cell­phone
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, in­vehicle
mapping or driving directions, email or database access. In most of these cases you will be using the LMU­
42x0™ 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 LMU­42x0™ is capable of sending and receiving. This interface allows System Integrators to
communicate directly with LMU­42x0'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 LMU­42x0™ in a variety of formats
Present historic information received from the LMU­42x0™, typically in a report/chart style
format
Request location updates from one or more LMU­42x0s™

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 build­up on ESD sensitive electronics is prevented. International standards are used
to define typical EPA and can be obtained for example from International Electro­technical 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 LMU­42x0’s™ main­board (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 non­functional 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 Over­Stress (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 LMU­42x0™ GPS Antenna to another LMU­42x0™ GSM
Antenna. Should one of the units be in a transmit mode the potential exists for the other unit to become
damaged. Therefore any LMU­42x0™ GPS Antenna should be kept at least four inches apart from any active
LMU­42x0™ 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 back­up battery into the trash. Consult your local waste
management facility for proper disposal instructions.
3.1.3 Environmental Specifications
The LMU­42x0™ 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 LMU­42x0™ was subjected to standard tests defined

jPOD™ Vehicle Bus Adaptor
The CalAmp jPOD Adapter is a J1939 compliant device that reads the parameters broadcast in the J1939 bus,
processes them and provides filtered vehicle data to the LMU­42x0™.
A script is written using a special software tool and loaded into the jPOD. This script defines the specific
parameters (PGNs/SPNs) to read, how to process them and how to send them to the host. The script does not
send any requests onto the bus.

3.6.1 3­Axis Accelerometer Input
The LMU­42x0™ 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.
3.6.2 Ignition and Inputs
The LMU­42x0™ provides up to 7 inputs. These 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 on­duty/off­duty meter
status or many others.
The ignition input is pulled to ground through the 10k resistance, where the other inputs can be configured to
be normally High (i.e. pulled to +12v through a 10k resistor) or Low (i.e. pulled to ground through a 10k
resistor). The diagrams below show how to connect the inputs in both a high­ and low­biased configuration:

The LMU’s and ioPOD;s outputs are designed to drive external relays. These outputs provide a high­current,
open­collector 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 shut­off 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.

4 Configuration and Activation
This section details how to quickly get an LMU­42x0™ 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
42x0™. (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 LMU­42x0™.
This device may not be supported for all the carriers or networks listed in this section (CDMA­Verizon,
CDMA­Sprint, HSPA, GSM), for product availability consult the CalAmp sales team.
4.1 Quick Start ­ General Config
All LMU­42x0s™ 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 LMU­42x0™ and connect a serial cable from the LMU to your laptop
2. Open a terminal session to the LMU­42x0™
3. Enter the address of the LM Direct™ server:

(32‐bit products only)
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 LMU­42x0™ and your handset
2. From the handset, send an SMS message to the LMU­42x0™ phone number:
!RP,2319,0,ddd.ddd.ddd.ddd
!RP,768,0,ddd.ddd.ddd.ddd
!RP,769,ppppp
(32‐bit products only)
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.

For certain operators, the LMU can auto­populate 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$APP PARAM 1024,35,1,1
To re­enable auto­provisioning, use:
AT$APP PARAM 1024,35,1,0
Auto­provisioning 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 LMU­42x0™ 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 book­keeping a little cleaner. You may also obtain this information by running a CSV report in
https://puls.calamp.com/wiki/LMU­42x0_Hardware_%26_Installation_Guide
25/47
1/28/2015
LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
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 ICC­ID (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 ICC­ID 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$APP
AT$APP
AT$APP
AT$APP
PARAM
PARAM
PARAM
PARAM
2306,0,“myAPN.myOperator.com”
2306,1,“myAPN.myOperator.com”
2314,0,“myUSername”
2315,0,“myPassword”
For a blank APN the following command can be used:
AT$APP PARAM 2306,0,“” (for a blank APN)
Only enter this next command if you have been given a non­zero PIN as any errors may lock you out of the
modem.
AT$APP 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:

4.4 Accessing the SIM
The SIM carrier is located on the right side of the LMU­42x0™ underneath the wireless modem (GSM or
HSPA). The SIM’s contacts should face upwards with the SIM notch oriented into the LMU­42x0™.

4.5 Activating a CDMA LMU­42x0™
Check with the CalAmp Sales team for availability of the LMU­42x0™ 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
MSN­D (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 LMU­42x0™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over­The­Air. A CalAmp LMU­
42x0™ will automatically use this system to attempt to self provision. This procedure assumes that the LMU­
42x0™ has never been provisioned or activated before.
1. Power on the LMU­42x0™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink several
times (i.e. more than twice) you will need to contact Verizon Wireless for further support on account
activation.
Once configured, you may verify that the LMU­42x0™’s modem has registered to the CDMA network. Enter:
AT$APP COMM STATUS?
The response should be similar to:

Note that the Phone Number should match the MDN value the carrier gave you. The last 10 digits of the IMSI
field should match the MIN/MSID value they gave you.
For devices that have had previous activations, an Over­The­Air activation process may be manually started
using a single AT Command:
AT$APP MODEM UPDATE
This command is also used to initiate an Over­The­Air PRL Update for devices that are already provisioned.
Users may also force a reactivation with the command:
AT$APP MODEM ACTIVATE
Keep in mind, however, this may cause the modem to lose its credentials and become unable to register to the
network.
4.5.2 Activating a CDMA LMU­42x0™ – Sprint
Activating an LMU­42x0™ on the Sprint CDMA network is identical to activating on the Verizon network.
1. Power on the LMU­42x0™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink several
times (i.e. more than twice) you will need to contact Sprint for further support on account activation..
Once configured, you may verify that the LMU­42x0’s™ modem has registered to the CDMA network. Enter:

5 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.
5.1 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 (for external devices)
Comm Antenna (for external devices)
Optional Components:
Input and output cables
Relays
LMU peripherals (i.e. Serial adapter, jPOD, TetheredLocator)
Host serial devices (e.g. PDAs, laptops, other serial devices)
5.2 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 multi­meter.
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 trouble­free 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.
5.2.1 Size and Placement of LMU Unit

30/47
1/28/2015
LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
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
42x0™.
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.
5.2.2 Placement of Antennas
There are effectively three options for placements of an antenna:
Roof­mount (magnetic or thru­hole)
Glass­mount
Covert (e.g. under the seat, dash, etc…)
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 3­dB gain whip. It mounts
with standard mounts (i.e. thru­hole, 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.
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.

LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
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 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.
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 stand­alone 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 rear­windshields are also acceptable.

LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
Examples OK(Yellow) and Poor(Red) internal antenna placements
5.2.3 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 main­board
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.
5.2.4 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.
5.2.5 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.
5.2.6 Cable Length
The RF cables which are provided for connecting to the LMU antennas should be used at the length provided.

33/47
1/28/2015
LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
Do not cut cables. Instead, coil any excess cable length, making sure not to crimp or flatten the antenna cable.
5.2.7 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.
5.2.8 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.
Two common methods are the use of Tamper Proof Sealant or creation of PEG Script to detect power loss or
GPS antenna disconnections.
5.3 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:
5.3.1 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 wind­shield.
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.
5.3.2 Connect power, ignition, and ground.
The power input (red wire) must be connected to a constant (un­switched) +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.

34/47
1/28/2015
LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
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 press­in fuse clips or other temporary measures.
DO NOT connect the power cable to the LMU at this time.
5.3.3 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.
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.
GPS Antenna Location
5.3.4 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.

5.4 Installation Verification
In many cases it is desirable to verify that an installed LMU­42x0™ is working properly. That is, installers
should verify that the GPS and communications functions of the LMU­42x0™ 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 LMU­42x0™. 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 LMU­42x0™ to obtain its current status.
5.4.1 Comm Verification
Installers should first verify that the LMU­42x0™ 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:
ATIC
Depending on the wireless network being used something similar to what is shown below will be displayed. It
is important to verify that 'Yes' values are displayed at the top for Data and Network registration and the
correct APN is displayed.

If any of the responses return Not­Acquired or Not­Registered (and the APN is correct), the wireless network
operator should be contacted for further troubleshooting.

LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
Please note that it may take several seconds (or longer) for the LMU­42x0™ to communicate with the modem
and acquire the wireless network.
5.4.2 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$APP GPS?
The response should be similar to:
Lat=3304713, Lon=‐11727730, Alt=0
Hdg=113 Spd=0 3D‐RTIME HDOP=130 nSats=7
Installers are looking for the 3D­RTIME setting along with a valid Lat, Long pair (i.e. something other than 0).
If the GPS receiver does not have a valid lock within 2­3 minutes, installers should check antenna placement
(see the Installation Notes section for placement suggestions), the antenna connector and that the antenna has a
clear view of the sky. For further troubleshooting, installers should contact CalAmp Support
(M2MSupport@CalAmp.com)
5.4.3 Inbound Verification
The last item to verify is that the LMU­42x0™ is sending data to the correct server. In general, this is a two­
step process that will need the aid of an observer on the back end. That is, a technician will have to be logged
in so they can monitor data coming into the backend mapping/vehicle management application.
First, verify that the LMU­42x0™ is using the correct Inbound IP address by using:
AT$APP INBOUND?
The response should be similar to:
INBOUND

1/28/2015
LMU­42x0 Hardware & Installation Guide ­ PULS Wiki
The installer will need to verify with a backend technician that the, URL (myURL.myCompany.com ), IP
address (ddd.ddd.ddd.ddd) and port () are correct.
The second step is to verify that the LMU­42x0™ is sending data. The best way to do this is to force the LMU­
42x0™ to send in an unacknowledged Event Report (i.e., its current GPS location) with the following
command:
AT$APP PEG SUNRPT 255
The LMU­42x0™ 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.
5.4.4 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:

Human Exposure Compliance Statement
Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS)
equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), § 2.1091
and § 2.1093, as appropriate.
CalAmp DataCom Inc. certifies that it has determined that the LMU­42x0™ complies with the RF hazard
requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart
E of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of
the equipment in accordance with all instructions provided.
The LMU­42x0™ is designed for and intended to be used in fixed and mobile applications. “Fixed” means that
the device is physically secured at one location and is not able to be easily moved to another location. “Mobile”
means that the device is designed to be used in other than fixed locations and generally in such a way that a
separation distance of at least 20 cm is normally maintained between the transmitter’s antenna and the body of
the user or nearby persons. The LMU­42x0™ is not designed for or intended to be used in mobile applications
(within 20 cm of the body of the user) and such uses are strictly prohibited.
To ensure that the LMU­42x0™ complies with current FCC regulations limiting both maximum RF output
power and human exposure to radio frequency radiation, a separation distance of at least 20 cm must be
maintained between the unit’s antenna and the body of the user and any nearby persons at all times and in all
applications and uses. Additionally, in mobile applications, maximum antenna gain must not exceed 3.2 dBi.
