Mounting the Modem
The MP 555 GPS can be mounted in the trunk of the vehicle,
under the dashboard, or under a front or rear seat.
Selecting a Mounting Location
16
When selecting a mounting location, consider the following
factors:
•
The modem should not be exposed to weather and
environmental conditions beyond the ranges listed in the
technical specifications on page 29. Avoid excessive heat
from the engine compartment, heaters, or the exhaust
system, and extreme cold from direct contact with air
conditioners or other cooling systems. Never immerse the
modem in water or any other liquid.
2130297
Page 17
Installing the MP 555 GPS Modem in a Vehicle
• If you are replacing an MP200 modem, the MP 555 GPS is
smaller, but can be mounted in the same location using
the existing mounting holes. The MP200 has six mounting
holes, and any four adjacent ones will line up with those
on the MP 555 GPS.
• Every device connected to the MP 555 GPS, as well as the
modem itself, should be grounded as appropriate for the
installation. (See “Grounding the Modem” on page 18 and
“Power Harness Grounding” on page 22.)
• Wiring and connections should be as simple as possible.
Cables for power, antennas, the computer, and any I/O
devices must be routed to their destinations without using
excess wiring.
• All connectors and the reset button should be easy to reach
and the indicator lights should be visible.
Mounting Procedure
To mount the MP 555 GPS:
1. Use the provided mounting template to mark the location
of the mounting holes.
2. Drill the required 5/32" pilot holes (unless you are reusing
holes from an MP200 modem mounting—see page 16).
3. Use the supplied mounting screws and washers to secure
the MP 555 GPS through the holes along the edge of the
case bottom.

Grounding the Modem
Note: Failing to prov
dedicated ground for each
piece of electrical equipment
can damage the equipment.
Note: If you are replacing an
MP200 modem, you can use the
MP200 power harness rather
than install ng the MP 555 GPS
power harness. The only
difference between the
harnesses is that the MP200
harness has a fused ground wire
whil
has an unfused ground wire.
i
e the MP 555 GPS harness
ide a
It is standard practice in automotive installations to provide a
good quality ground for each piece of electrical equipment. In
most cases, the modem should be grounded by connecting the
black ground wire of the power harness either to the vehicle
chassis or to the negative terminal of the battery.
If other devices connected to the modem (such as a notebook
computer) are not properly grounded, there is some risk that
the other device will ground itself through the cable
connecting it to the modem. This creates a hazardous situation
and could cause equipment damage. If you cannot properly
ground these devices, a potential solution is to install a fuse in
the ground return wire.
The power harness for the MP 555 GPS modem has 5 A fuses
on the red power wire and the white ignition sense wire, but
on the black ground return wire. (See “Power Wiring” on
not
page 20.)
Ground screw
Figure 2-7: The ground screw connector (bottom) on the connector panel.
To facilitate other ground schemes, a ground screw is
provided on the connector panel of the MP 555 GPS. Use of
this ground screw is not required as long as the power harness
is properly grounded. (Use a 16-gauge wire if you choose to
use the ground screw.

CDMA RF Antennas
The MP 555 GPS requires an approved CDMA RF (Radio
Frequency) antenna. The antenna must have 50 ohms
impedance and a cable with a male TNC connector, as well as
the following characteristics:
• The total maximum gain, including the cable loss, must
not exceed 5.2 dBi (if the antenna operates on the PCS
band) or 6 dBi (if the antenna operates only on the Cellular
band).
• The antenna must transmit and receive on the necessary
frequency bands in your coverage area. The MP 555 GPS
supports these RF bands:
· 1900 MHz (PCS)
· 800 MHz (Cellular)
A dual-band antenna that supports both frequencies can be
used. If your MP 555 GPS will only be connected to networks that use one of the bands, an appropriate singleband antenna is sufficient. Contact your service provider
for information about radio bands used in your area.
Figure 2-8: The MP 555 GPS’s SMA connector
for the GPS antenna, and the TNC connector
for the CDMA RF antenna.
The MP 555 GPS requires a CDMA
RF antenna to connect to the CDMA
wireless network. If the built-in GPS
module is used, it requires a
dedicated GPS antenna, or a combination antenna with cables for both
antenna connectors on the modem.
For more information about antennas for your installation,
contact your account manager at your reseller or at Sierra
Wireless.
GPS Antennas
If you are installing a GPS antenna, it connects to the
MP 555 GPS modem using a male SMA connector. Contact
your account manager at your reseller or at Sierra Wireless for
more information about compatible GPS antennas.

Antenna Locations
When selecting locations for the GSM CDMA RF and GPS
antennas:
Refer to the documentation provided with each antenna to
•
determine whether it requires a ground plane.
Ensure that the CDMA RF antenna is mounted at least
•
20 cm (8 inches) from vehicle occupants and bystanders.
Ensure that all radio antennas (CDMA RF, GPS, CB radio,
•
car radio) are separated as much as possible from each
other. Antennas should never be mounted less than 30 cm
(1 foot) apart.
Installing Antennas
To install the CDMA RF and GPS antennas:
Mount each antenna according to the instructions
1.
provided with it.
Thread the antenna cables through the car to reach the
2.

cable into the modem’s TNC (for the CDMA RF antenna)
or SMA connector (for the GPS antenna). Hand-tighten the
connectors; do not use tools.
Note: To avoid RF nterference
problems and possible damage
to the MP 555 GPS, do not
power on the modem before
connecting the CDMA IS-95 RF
antenna.
i
Power Wiring
In a typical installation, the MP 555 GPS is connected to the
vehicle’s battery with the supplied power harness (or if an
MP200 modem was previously installed, with the MP200
power harness). The MP 555 GPS supports a voltage range
between 9 VDC and 36 VDC, and is designed for both 12 VDC
and a 24 VDC vehicle electrical systems.

relevant operational data before powering off.
Ignition sense options
There are three ways to connect the ignition sense wiring:
•
Engine on only. The white ignition sense wire can be
connected to the vehicle’s ignition switch so that the
MP 555 GPS is powered on only when the ignition key is
switched to the full “On” position, i.e. when the engine has
been started. In this configuration, the engine must be running for the modem to be on.
—or—
Accessory on. The white ignition sense wire can be
•
connected to the vehicle’s ignition switch so that the
MP 555 GPS is powered on when the ignition is switched
to “Accessory” mode. In this configuration, the modem is
whenever other vehicle electrical devices can be switched
on
—such as when the radio and windshield fan can run.
on
—or—
Note: If you choose to install a
separate switch, it must still be
connected to the white gnition
sense wire, not the red battery
wire, so that the modem can
perform a controlled shutdown,
as described on page 21.
i
•
Separately switched. The white ignition sense wire can be
connected to a separate switch, mounted under the
dashboard or in another convenient location, which allows
the MP 555 GPS to be turned on or off regardless of the
position of the ignition key. In this configuration, the
modem can be powered on or off even if the key is not in the
ignition.
The modem also has a “Power Off Timer”. When power is
removed from the ignition sense wire, the modem remains on
for the period defined by the Power Off Timer. The maximum
(
duration is four hours.) The Power Off Timer is configured in
Watcher. See the online help for details.
Power Harness Grounding
The black ground wire from the power harness must be
connected to the grounded negative terminal of the vehicle
battery, or another appropriate electrical ground if you are
using an alternate power source. Failing to ground the power
harness properly may damage the MP 555 GPS, may cause
radio interference, and can be dangerous. (See “Grounding the
Modem” on page 18.
The ground wire in the MP 555 GPS power harness is not
fused.
)

Installing the MP 555 GPS Modem in a Vehicle
Making Proper Power Connections
Connecting the MP 555 GPS’s power wires properly is
important—poor connections can damage the wiring, the
modem, or the vehicle’s electrical system, and can also be
dangerous.
Note: Ensure that all wires are
correctly spliced or crimped.
Improper grounding and wire
connections may lead to
equipment damage or safety
hazards.
Correct wire splicing
The wires of the power harness may be spliced to the car
wiring. Proper splicing is essential to reliable operation of the
MP 555 GPS. Do NOT use “quick taps”; they reduce the
integrity of the wire that is cut and let moisture into the cable.
An appropriate method of splicing is to strip a small portion of
the insulation, solder the wires together, then heat-shrink the
connection to re-insulate it.
Using crimp terminals
If suitable terminal connection points are available on the
vehicle for power and ignition sense, then using automotive
crimp terminals is recommended. When using crimp
terminals, do not leave bare wire exposed. Do not use a crimp
terminal for more than one wire unless it is designed for that
purpose.
Powering On the Modem
Once the MP 555 GPS modem is powered on, the Power and
GPS indicators on the indicator panel should light, either
solid-on or flashing.
Data Wiring
The MP 555 GPS modem connects to:
A computer through the DB9 serial or USB connector.
•
Other optional devices through the DB15 I/O connector.

Completing the Installation
Once you have mounted the MP 555 GPS and connected all the
appropriate cables and antennas, you can power on the
computer and the modem.
When you install and configure the supplied software from the
included CD (as described in the MP 555 GPS Software Instal-lation, Configuration, and Integration Guide), you can then test
whether the modem is able to connect to and transmit data
over the CDMA network, and (if you have connected a GPS
antenna) whether the MP 555 GPS can determine its position.
