2.2 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.
2.2.1 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-4200™.
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.

2.2.2 Placement of Antennas
There are effectively three options for placements of an antenna:
Roof-mount (magnetic or thru-hole)
Glass-mount
Covert (e.g. under the seat, dash, etc…)
2.2.3 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.
2.2.4 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.

LMU-4200™ Hardware and Installation Guide
V1.0.9 November 13, 2010
Copyright ©CalAmp DataCom Inc 2010 - 14 - CalAmp Proprietary & Confidential
7 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.
2.2.5 Access to the SIM (Subscriber Identity Module) Card
When used in a GSM or HSPA 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.
2.2.6 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.
2.2.7 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.

LMU-4200™ Hardware and Installation Guide
V1.0.9 November 13, 2010
Copyright ©CalAmp DataCom Inc 2010 - 15 - CalAmp Proprietary & Confidential
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.
2.2.8 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.
2.2.9 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.
2.2.10 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.

2.3 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:
2.3.1 Place the LMU unit in the vehicle.
Typically, the LMU should be placed under the passenger seat or dashboard of the vehicle.
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.
2.3.2 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.
2.3.3 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.
Figure 8 - GPS Antenna Location
2.3.4 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.
