1: Introducing the MP Modem  
Note: Do not connect the MP  
modem to a USB port on a  
computer before installing the  
The Sierra Wireless MP modem provides a wireless network  
connection for portable computers in vehicles or offices.  
If the MP modem is installed in a vehicle, it typically is  
mounted in the trunk and connected to a notebook computer  
in the passenger compartment. A radio frequency (RF) antenna  
mounted on the roof of the vehicle enables the MP modem to  
communicate through a wireless network to a host computer.  
A builtin Global Positioning System (GPS) module provides  
location and heading data that can also be remotely monitored.  
The MP modem has a rugged design that allows it to  
withstand the vibration, shock, humidity, and extremes of  
temperature experienced in the normal operation of police,  
emergency, utility, and field service vehicles.  
You can use the network connection provided by the MP  
modem to access shared data, browse the Internet, and send  
and receive email and text messages. The MP modem also  
allows for sensors, gauges, and alarms (such as panic buttons)  
to be installed in vehicles and remotely monitored from a  
central location.

MP880W Modem User Guide  
Network connections  
The MP modem operates over the following networks, with  
connectivity and speed dependent on your service provider  
and account:  
High Speed Uplink Packet Access (HSUPA)—up to  
2.0 megabits per second (Mbps)  
Universal Mobile Telecommunications System  
(UMTS)—up to 384 kilobits per second (kbps)  
Enhanced Data GSM Environment (EDGE)—up to  
236 kbps  
General Packet Radio Service (GPRS)—up to 56 kbps  
Circuit switched (dialup) data connections  
Once a connection is established, you can open your browser  
and connect to web sites and access other Internet services  
such as email.  
Accounts and coverage  
You must set up an account with a service provider for each  
MP modem you install. After installing the MP modem  
software, you must configure it to use an account.  
The service provider supplies a Subscriber Identity Module  
(SIM) card—sometimes called a smart card or smart chip—for  
each account. The SIM card provides the MP modems identity  
on the network. It contains account information and must be  
inserted in the MP modem for the MP modem to operate. (See  
The ability of the MP modem to obtain service and the type of  
service obtained in any area is determined by several factors:  
Network proximity and HSUPA availability To obtain  
service, you must be within the coverage area of a network  
operating in one of the radio frequency bands supported by  
the MP modem. The type of connection depends on the service  
available in that area. For example, there are areas with UMTS  
service in which HSUPA has not yet been implemented.  
Roaming If you are within the coverage of a network  
operated by a different service provider, your ability to obtain  
service depends on whether a roaming agreement exists  
between your service provider and the one operating your  
current local network. There may be additional fees for  
roaming service. Contact your reseller or service provider for  
information.

Introducing the MP Modem  
Account provisions Your account may restrict usage of  
certain networks or may limit your connection time or data  
transmission.  
Supported GSM radio frequencies  
The MP modem has triband capability on HSUPA and UMTS  
networks, operating on:  
850 MHz  
1900 MHz  
2100 MHz  
and quadband capability on EDGE and GPRS, operating on:  
850 MHz  
900 MHz  
1800 MHz  
1900 MHz  
Connection methods  
You can connect the MP modem to a USB, Ethernet (RJ45), or  
serial (DB9) port on a computer. When connected to a USB or  
Ethernet port, the MP modem behaves like a network card.  
When connected to a serial port, the MP modem behaves like a  
dialup modem.  
The MP modem also supports connections via IEEE802.11b/g  
(MP595). See Chapter 6 for more details.  
Virtual serial port  
The MP modem supports four virtual serial ports (VSPs).  
Three are reserved for internal use by the MP modem. The  
remaining VSP, which is called Sierra Wireless Application  
Interface 2, is assigned to a specific COM port that varies  
between users. This VSP can be used, for example, to send AT  
®
commands, or to run applications such as HyperTerminal .  
Special MP modem modes such as GPS that are supported on  
a serial port are also available on the virtual port. For example,  
with the virtual port enabled, a mapping application on your  
computer that normally listens for GPS messages on a serial  
port listens for those same messages on the virtual port.

MP880W Modem User Guide  
The MP modem VSPs are available on both USB and Ethernet  
interfaces. For information on enabling a virtual serial port, see  
the MP 3G Modems AT Command Reference manual (document  
#2130810).  
VPN support for RNAP  
This feature allows for the exchange of Remote Network  
1
Access Protocol (RNAP ) data between the MP modem and a  
remote server accessible only through a Virtual Private  
Network (VPN) connection. When using this feature, you must  
have 3G Watcher running on the computer.  
The MP modem sends RNAP data over Ethernet or USB to 3G  
Watcher on the computer. 3G Watcher places the RNAP data in  
a User Datagram Protocol/Internet Protocol (UDP/IP) packet  
and sends it over the VPN connection to the server. When 3G  
Watcher receives a UDP/IP packet containing RNAP data over  
the VPN connection, it disassembles the packet and sends the  
RNAP data to the MP modem.  
You can enable this option using 3G Watcher software or AT  
commands. See the 3G Watcher online help and the MP 3G  
Modems AT Command Reference manual (document #2130810)  
for details.  
Software  
The MP modem comes with the following software:  
3G Watcher, the software for the MP modem which allows  
you to manage and monitor your connections.  
The driver that forms the interface between the MP  
modem and your Windows operating system.  
The firmware that is stored in nonvolatile memory.  
The MP modem has an embedded radio module (a  
Mini Card 8775), also made by Sierra Wireless, Inc. There  
are two firmware programs on the MP modem—one  
stored on the controller board of the MP modem and one  
on the radio module.  
The firmware was loaded into the radio module and con‐  
troller board when the MP modem was assembled. As new  
1. RNAP is a Sierra Wireless proprietary protocol that encapsu-  
lates the MTP data that is sent to and from the MP modem. It  
ensures that both the MP modem and remote host recognize  
the data packets. See The Monitoring and Tracking Protocol  
Guide on page 18.

Install the MP modem  
Step 1—Mount the MP modem  
Note: Power off the MP modem,  
your computer, and any other  
devices while you are connecting  
cables.  
If you are using the MP modem in a vehicle, it is usually  
mounted in the trunk, but other possibilities are under the  
dashboard or a seat.  
Select a location for the MP modem  
When selecting a mounting location, remember the following:  
Do not expose the MP modem to weather and environ‐  
mental conditions beyond the ranges listed in the environ‐  
mental specifications on page 74. 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 it in  
any liquid.  
If you are replacing an MP modem, you can mount the  
new MP modem in the same location using the existing  
mounting holes.  
Every device connected to the MP modem, as well as the  
MP modem itself, should be grounded. (See “Ground the  
Route cables to their destinations without using excess  
wiring.  
Make sure all connectors and the reset button are easy to  
reach and the indicator lights are visible.  
Mounting the MP modem  
To mount the MP modem:  
1. Use the provided mounting template to mark the location  
of the mounting holes.  
2. Drill 5/32ʺ pilot holes (unless you are reusing holes from a  
previous MP modem mounting).

MP880W Modem User Guide  
Use the supplied mounting screws and washers to secure the  
MP modem through the holes along the edge of the case  
bottom.  
Figure 3-3: Mounting the MP modem. Arrows indicate the mounting holes. The  
front cover is open for illustration purposes only. Close it before mounting.  
Ground the MP modem  
Note: Electrical installations are potentially dangerous and should be  
performed by personnel thoroughly trained in safe electrical wiring  
procedures for vehicles.  
Automotive installations usually provide a good quality  
ground for each piece of electrical equipment. In most cases,  
ground the MP modem by connecting the black ground wire  
of the power harness to either the vehicle chassis or to the  
negative terminal of the battery.  
If a device connected to the MP modem, such as a notebook  
computer, is not properly grounded, it may ground itself  
through the cable connecting it to the MP modem. This creates  
a hazard and could cause equipment damage. If you cannot  
properly ground a device, a potential solution is to install a  
fuse in the ground return wire.  
The power harness has 5 A fuses on the red power wire and  
the white ignition sense wire, but not on the black ground

Hardware and Software Installation  
You can also use a ground screw on the connector panel of the  
MP modem. Use a 16gauge wire if you choose to use a ground  
screw. A ground screw is not required as long as the power  
harness is properly grounded.

Note: Tighten cables connected  
to the MP modem by hand. Do  
not use tools.  
Step 2—Mount the antennas and install  
the cables  
The MP 880W modem has one Main RF antenna connector and  
one GPS antenna connector. The MP 595W has an additional  
RF antenna connector for an AP antenna. The MP modem  
requires an RF antenna to connect to the wireless network.  
The builtin GPS module requires a dedicated GPS antenna or  
a combination antenna with cables to both the Main RF and  
GPS antenna connectors on the MP modem.  
If you already have an MP modem combination GPS antenna,  
you can reuse it with your new MP modem. This antenna has  
two leads—one for Main RF (TNC connector) and one for GPS  
(SMA connector).  
Main RF antenna  
Use an approved Main RF antenna to connect to the wireless  
network. The antenna must have 50 ohms impedance and a  
cable with a TNC connector, as well as the following character‐  
istics:  
The total maximum gain, including cable loss, must not  
exceed 4 dBi (if the antenna operates on the PCS band) or  
5 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 modem  
supports these RF bands:  
· HSUPA and UMTS networks:  
· 850 MHz  
· 1900 MHz  
Rev 1.5 Jul.08

MP880W Modem User Guide  
· 2100 MHz  
· EDGE and GPRS networks:  
· 850 MHz  
· 900 MHz  
· 1800 MHz  
· 1900 MHz  
If your MP modem 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.  
Access point antenna. The 2.4 GHz AP antenna connects to  
the AP antenna connector on the rear of the MP modem.  
For more information about antennas for your installation  
contact your account manager.  
GPS antenna  
The GPS antenna connects to the MP modem using a male  
SMA connector. Contact your account manager for more infor‐  
mation about compatible GPS antennas.  
AP antenna (MP 595880W only)  
The AP antenna must be installed by an RF professional. The  
AP antenna connects to the MP modem using a reverse  
polarity male SMA connector.  
Note: The WiFi antennas  
approved for use with this device  
must be of either a PCB omni  
antenna with a gain of no more  
than +2 dBi, or a dipole antenna  
with a gain of no more than  
+5dBi. No other antennas are  
approved for use with this  
device.  
Antenna locations  
When selecting locations for the Main RF, GPS, and AP  
antennas:  
Refer to the documentation provided with each antenna to  
determine whether it requires a ground plane.  
Ensure that the Main RF antenna is mounted at least 20 cm  
(8 inches) from vehicle occupants and bystanders.  
Ensure that all radio antennas (Main RF, GPS, CB radio,  
car radio) are mounted at least 20 cm or more apart (30 cm  
recommended).  
(MP 595875W only) Ensure that the AP antenna is  
mounted at least 20 cm from the Main RF antenna.

Hardware and Software Installation  
Note: Do not install an on/off  
switch on the main (red) battery  
line, or connect the white ignition  
sense wire to the red battery  
wire. Both configurations bypass  
the MP modem's controlled  
shutdown sequence, and may  
cause data loss and subsequent  
power-on problems. Incorrect  
wiring may also drain the vehicle  
battery.  
The MP modems power on/off is controlled by the ignition  
sense line (white wire) using internal software, rather than a  
hard on/off switch on the red power line. The red, black, and  
white wires connect to the battery and ignition switch as  
shown in the power harness wiring diagram.  
Note: The battery cable used for a car, truck, or other mobile  
connection must be less than 3 meters in length.

When the white ignition sense line is pulled high (5 to  
36 V), the MP modem powers on.  
When the ignition sense line is pulled low (less than 2 V),  
the MP modem performs a controlled shutdown sequence  
(under software control), deregistering and saving any  
relevant operational data before powering off.  
Ignition sense options  
There are three ways to connect the ignition sense wiring:  
Engine on only. Connect the white ignition sense wire to  
the vehicles ignition switch so that the MP modem is  
powered on only when the ignition key is switched to the  
full “On” position, that is, when the engine has been  
started. In this configuration, the engine must be running for  
the MP modem to be on.  
—or—  
Accessory on. Connect the white ignition sense wire to the  
vehicles ignition switch so that the MP modem is powered  
on when the ignition is switched to Accessory” mode. In  
this configuration, the MP modem is on whenever other  
vehicle electrical devices can be switched on—such as when the  
radio and windshield fan can run.

wire to a separate switch mounted in a convenient  
location, which allows the MP modem to be turned on or  
off regardless of the position of the ignition key. In this  
configuration, the MP modem can be powered on or off  
even if the key is not in the ignition.  
The MP modem also has a “Power Off Timer”. When power is  
removed from the ignition sense wire, the MP modem remains  
on for the period defined by the Power Off Timer, up to a  
maximum of 240 minutes. The Power Off Timer is configured  
in 3G Watcher. See the online help in 3G Watcher for details.  
Ground the power harness  
You must connect the black ground wire from the power  
harness to the grounded negative terminal of the vehicle  
battery, or another appropriate electrical ground. Failing to  
ground the power harness properly may damage the MP  
modem, may cause radio interference, and can be dangerous.  
in the MP modem power harness is not fused.  
Power connections  
Connecting the MP modems power wires properly is  
important—poor connections can damage the wiring, the MP  
modem, or the vehicles electrical system, and can 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  
You can splice the wires of the power harness to the car wiring.  
Proper splicing is essential to reliable operation of the MP  
modem. 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 heatshrink the  
connection to reinsulate it.  
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.

Step 4—Connect the MP modem to  
computer cable  
The MP modem connects to:  
A computer through a USB, Ethernet, or serial port  
Other optional devices through the DB15HD I/O connector  
Note: Do not connect the MP modem to the computer until you have  
installed the software.  
The MP modem connects to a computer using:  
A USB cable (with a Type A connector on the computer  
end and a Type B connector on the MP modem end). The  
maximum of the USB cable is 5.5 m (18 feet). These cables  
are readily available from many suppliers.  
An Ethernet cable with RJ45 connectors. The type of cable  
you use affects the performance of the MP modem. The  
minimum requirement for the Ethernet cable is an  
unshielded twisted pair (UTP) cable, category 3 or 4. For  
better performance, use a shielded, category 5 cable. The  
theoretical maximum length is 100 m (328 feet).  
You can connect the MP modem Ethernet port directly to a  
computer or other Ethernet device with either a crossover  
or a straightthrough cable.  
Note: 5.5-meter cable part  
number: 6000083.  
A serial cable (with a DB9 connector on the MP modem

4: MP Modem Operation  
Operating the MP modem requires some knowledge of both  
the MP modem hardware and the 3G Watcher software. This  
chapter describes the basics of each.  
Turning the MP modem on and off  
If the MP modem is installed in a vehicle, the way in which the  
MP modem is wired determines how it is powered on and off.  
In most cases the power supply for the MP modem is the  
vehicleʹs electrical system and the MP modem is powered on  
and off in one of these ways:  
Engine on. The MP modem is powered only when the  
ignition is on. (The MP modem is only on when the engine  
is on.)  
—or—  
Accessory on. The MP modem is powered when the  
ignition is switched to ʺAccessoriesʺ. (This allows the MP  
modem to be powered when the engine is off.)  
—or—  
Separately switched. The MP modem is connected to a  
separate on/off switch so that it can be turned on and off  
independently of the engine and vehicle accessories.  
Rather than cutting power to the MP modem, the ignition key  
or power switch allows the MP modem to perform a controlled  
shutdown sequence that avoids data loss. (You can also set the  
MP modem to wait up to 240 minutes after the power switch  
has been turned off before it shuts down.)

Non-NAT mode  
In nonNAT configuration, you can connect only one client  
device, such as a computer to the MP modem, as shown in  
In this mode, the IP address obtained from the external  
network is passed directly to the client device, which is why  
there can be only one client.

In NAT mode, you can connect up to 10 devices to the MP  
modem using Ethernet connections and up to 10 additional  
devices using WAP.  
In this mode, the IP addresses assigned by the MP modem to  
the client devices are private IP addresses. The MP NAT  
manages the translation of IP addresses and ports between the  
local and external networks.  
The following illustration shows a sample network with 4  
computers, two connected on an Ethernet LAN and two  
connected with WAP.

Configuring the Router Functions  
Enable the router  
The router features are enabled when NAT is enabled. By  
default, NAT is disabled. To enable NAT:  
1. In Watcher, select Tools > Options > MP.  
2. Under Network Settings, select Network Address Trans‐  
lation (NAT) and from the dropdown list select Enabled.  
The MP modem automatically resets in order for the  
change to take effect.  
File and resource sharing over LAN  
When NAT is enabled on the MP modem, its router capabil‐  
ities allow you to share files and resources such as printers,  
fax, etc. between computers on the LAN.  
Static IP and TCP/UDP port  
forwarding in NAT mode  
If desired, you have the option to set up static IP addresses and  
TCP/UDP port forwarding. The following sections describe  
these optional settings in more detail.  
Set up static IP addresses  
Static IP addresses are used to assign a predefined IP address  
to a specific client on the local network. The client is identified  
by its MAC address. When Static IP is used in conjunction with  
NAT port forwarding, it allows a server application to reside  
on the local network and receive unsolicited data/requests  
from a remote client on the external network.  
Private IP addresses in the range 192.168.1.20 to 192.168.1.254  
for Ethernet and 192.168.2.20 to 192.168.2.254 for wireless LAN  
are available for use as static IP addresses.  
You can set up a maximum of 10 static routes, and these routes  
can apply to either an Ethernet or WAP interface. To set up  
static routing, you need to know the MAC address of the  
computers you want to configure.  
To configure static routes:  
1. Unlock the MP modem configuration. In Watcher, select  
Tools > AT Commands and enter the AT!MPCFGOPEN=ʺxʺ,  
where “x” is the password. (Default password is MP3G,  
e.g. AT!MPCFGOPEN=ʺMP3Gʺ)

Configuring the Router Functions  
2. In Watcher, select Tools > AT Commands, and use the  
AT!MPSTATICROUTE command to set up static routing.  
For more information, see the 3G MP Modems AT Command  
Reference manual (document #2130810).  
3. Reset the modem. Select Tools > AT Commands, and use the  
AT!MPGRESET command to reset the MP modem.  
4. Click OK.  
Set up TCP/UDP port forwarding  
Setting port forwarding on the MP modem causes it to forward  
unsolicited external IP packets with certain TCP or UDP Port  
IDs to specific IP addresses on the local network. If the IP  
addresses specified are static (that is, tied to a deviceʹs MAC  
address), then the packets are always forwarded to specific  
devices. This is required when running a server application on  
the local network.  
When port forwarding is set up, the MP modem routes specific  
UDP or TCP packets from the Internet to a specified port on a  
specific computer (or other device) on the local network.  
To configure port forwarding:  
1. Unlock the MP modem configuration. In Watcher, select  
Tools > AT Commands and enter the AT!MPCFGOPEN=ʺxʺ,  
where “x” is the password. (Default password is MP3G,  
e.g. AT!MPCFGOPEN=ʺMP3Gʺ)  
2. Select Tools > AT Commands and use the AT!MPPORTMAP  
command to configure the ports on the MP modem and  
the computer you want to direct the packets to. You will  
need to know the MAC address for the computer you want  
to configure. For more information, see the 3G MP Modems  
AT Command Reference manual (document #2130810).  
3. Reset the modem. Select Tools > AT Commands, and use the  
AT!MPGRESET command to reset the MP modem.

6: Configuring the MP Modem to  
Report GPS and I/O Data  
The MP modem is capable of reporting position and heading  
information using the embedded GPS module, as well as the  
status of sensors, gauges, and alarms connected to the I/O  
(Input/Output) port. The MP modem is typically installed in a  
fleet of vehicles with the GPS and/or I/O data being sent to a  
central office or dispatch for processing.  
This chapter describes how to implement local reporting of  
GPS and I/O data. Chapter 7 describes how to configure your  
MP modem to exchange data with your private network.  
GPS configuration and  
reporting  
GPS receivers use an array of orbiting satellites operated by the  
United States Department of Defense to triangulate their  
coordinates on the Earths surface. In order to use the GPS  
module in the MP modem, a GPS antenna must be connected  
to the MP modem. (The installation requires either two  
antennas—one Main RF and one GPS—or a single combination  
RF/GPS antenna.)

GPS protocols and commands  
Note: The “MP 3G Modems  
TAIP Reference manual”  
(document #2130312) provides  
a description of the TAIP  
commands that can be used with  
the MP modem. This is available  
Information about Trimble GPS  
modules, including more  
documentation on TAIP  
commands, is available at  
More information on NMEA  
message standards is available  
The GPS module supports two methods of reporting naviga‐  
tional information, using either the TAIP (Trimble ASCII  
Interface Protocol) or NMEA (National Marine Electronics  
Association) protocols. The GPS module is preconfigured for  
TAIP. If you are using a GPS application that requires data to  
be reported according to the NMEA protocol, the MP modem  
must be reconfigured using an AT command. (See the MP 3G  
Modems AT Command Reference manual (document #2130810.)  
NMEA is a reporting protocol only, while TAIP provides the  
ability to send commands to the module to query for infor‐  
mation and configure reports. When the MP modem is set for  
TAIP, commands can be sent to the MP modem in these ways:  
Using 3G Watcher  
Using AT commands  
TAIP commands can be used to:  
Query the MP modem for its current position, heading,  
and speed  
Enable and disable automatic reporting of GPS data, and  
set the interval at which automatic reports are sent  
Configure the format of reports  
GPS display in 3G Watcher  
To view 3G Watchers GPS Display window, which reports  
latitude, longitude, speed, direction, altitude, and local and  
1
UTC time , select Tools > Display GPS or doubleclick the GPS  
icon on the main 3G Watcher window.  
From a cold start (where the MP modem is powered on with  
no stored navigational data), it may take up to 39 seconds for  
the GPS module to obtain satellite fixes and begin reporting.  
1. UTC replaces Greenwich Mean Time as the basis for  
standard time throughout the world. UTC, which uses  
atomic measurements rather than the Earths rotation, is  
the equivalent of mean solar time at the prime meridian  
(0° longitude).

The I/O port on the MP modem allows for remote monitoring  
of gauges, sensors, and alarms. You can use this feature to  
display readings from instruments or gauges and to remotely  
monitor panic buttons or alarms.  
This section describes how to connect and configure these I/O  
devices to work with the MP modem.  
Connecting these devices requires that you make a customized  
I/O cable. The cable must have, at one end, whatever connector

Density DB15 connector. The cable wires must pin to the  
appropriate pin numbers on the I/O connector. The pinouts are  
described in the next section.  
The maximum length of the I/O cable is 15 feet.

Digital input devices  
Digital input devices are those that have only two states and  
send a signal to the MP modem in one of those states. An  
example of a digital input device might be a gun rack alarm  
that sends a signal to the MP modem any time the gun rack is  
open. Another example would be a panic button that sends a  
signal to the MP modem when it is pushed.

Configuring the MP Modem to Report GPS and I/O  
Data  
A digital input can be connected to four of the pins on the  
DB15HD connector: Pins 3, 4, 11, and 12. (Pins 3 and 11 could  
alternatively be used for digital output.)  
Note: Before using the input/output lines, you must configure them as  
inputs or outputs.  
Typically a digital input device should be connected between  
Ground (Pin 10) and the input port (Pin 3, 4, 11, or 12).  
Figure 6-2: A button wired to Pin 4 (digital input) and Pin 10 (Ground).  
The pins report a logic high on an input of 3.45 VDC. An  
internal pullup resistor provides a high condition when the  
switch is open.  
The digital input pins report a logic low on an input between  
0 VDC and 0.8 VDC. Sinking the input pin to ground yields a  
logic low (0x00) when the port is polled.  
If you configure the MP modem to send data to a network  
server, digital input data can be remotely monitored.  
Example: panic button connections  
An I/O cable for a panic button requires a wire to one of the  
digital input or I/O pins (such as #3) and one wire to the  
Ground pin (#10).

Digital output devices  
Digital output devices are those that have only two states and  
the state is controlled by a signal from the MP modem. Any  
device that is to be switched on and off from 3G Watcher  
would be installed as a digital output device.  
A digital output can be connected to two of the pins on the  
DB15HD connector: Pins 3 and 11. (These can be used for  
either input or output.)  
Note: Before using the input/output lines, you must configure them as  
inputs or outputs.  
Typically a digital output device should be connected between  
Ground (pin 10) and the output port (Pin 3 or 11).  
Figure 6-3: Wiring for using Pin 3 (digital output) as an electronic switch. Pin  
10 is Ground.  
The digital I/O ports provide opencollector output to a  
maximum of 500 mA.  
Analog input devices  
Analog input devices are those that generate a signal of  
varying voltage, based on the state of an instrument or gauge.  
An example of an analog input device might be a sensor that  
detects the vehicles speed.  
An analog input can be connected to four of the pins on the  
DB15HD connector: Pins 7, 8, 14, and 15.

Configuring the MP Modem to Report GPS and I/O  
Data  
Typically an analog input device should be connected between  
Ground (pin 10) and the input port (Pin 7, 8, 14, or 15).  
Figure 6-4: A sensor wired to Pin 7 (analog input) and Pin 10 (Ground).  
The analog input ports use a 10bit (1024step) analogto‐  
digital converter over a range from 0 to 3.45 VDC, yielding a  
digital step resolution of 0.0032 V.  
Example: analog sensor connections  
An I/O cable for an analog sensor requires a wire to one of the  
analog input pins (such as #7) and one wire to the Ground pin  
(#10).  
I/O configuration using AT or 3G Watcher  
commands  
Once a sensor, gauge, button, or switch is physically connected  
to the MP modem, the MP modem must be configured to  
manage the input from, or output to, the device. This configu‐  
ration can be done using either AT commands or using 3G  
Watcher.  
For a list of AT commands, please see the MP 3G Modems AT  
Command Reference manual (document #2130810).  
There are separate windows in 3G Watcher for configuring the  
analog and digital ports.

To configure an analog sensor or gauge, select the tab that  
corresponds to the pin you are using and complete the fields as  
follows:  
Label: Enter a description of the sensor or gauge (Measured  
Voltage, Vehicle Speed, etc.), up to 20 characters long.  
Raw value: Shows the analog value from the input (read‐  
only). The analog input has a 10bit (1024step) resolution,  
so the raw value range is between 0 and 1023.  
Zero scale: Enter the minimum value for the units you are  
reporting (used to convert the raw analog value of zero).  
Full scale: Enter the maximum value for the units you are  
reporting (used to convert the raw value of 1023).  
Current value: Shows the resulting converted value using  
the zero and full scales entered.  
Unit: Specify the units of the input (volts, km/h, etc.), up to  
20 characters long.  
Example  
If you are measuring temperature, and the thermometer you  
have connected to the I/O connector measures between 30  
(raw value 0) and +50 (raw value 1023) degrees Celsius, then  
your zero scale is -30.0 and your full scale is 50.0. Your label  
could be “Temperature”, and units, “degrees C”.  
The measurements are calculated for the 81degree range  
(between 30 and +50), which is divided into 1024 steps  
(0.0791 degrees per unit step). A reading of 25 degrees  
(56 degrees above the minimum) would therefore show a raw  
value of 708 (56 degrees/0.0791 degrees per unit).

7: Sending Data to Your Network  
Application  
This chapter discusses how to configure the MP modem to  
send GPS and I/O data to a network server. This is a simple  
process, but if there are any firewalls on your network or your  
service providers network, the data must be routed through or  
around the firewall. A general discussion of some methods of  
dealing with firewalls is provided.  
This chapter also explains how to retrieve the Unique Mobile  
Device ID from the MP modem. This is the number that  
uniquely identifies each MP modem. Any application that uses  
the GPS and I/O data from the MP modem requires this  
number.  
Configure the MP modem to  
route data to a server  
Note: For a full list of AT  
The protocol that defines how MP modem data is packaged is  
called MTP (Monitoring and Tracking Protocol). You can  
configure MTP in 3G Watcher by selecting Tools > Options >  
MP > Monitor and Tracking, or by using the AT command  
AT!MPMTCONF and the appropriate parameters.  
commands and their parameters,  
see the MP 3G Modems AT  
Command Reference manual  
(document #2130810).  
The MP modem provides four independent reporting engines,  
allowing data to be sent to four different destinations. You can  
specify the destination IP address and port number for each  
engine. This allows, for example, GPS data to be sent to one  
host application, and I/O data to be sent to another.  
You can also specify the values for the timers that determine  
the frequency with which the data is to be sent.  
Report frequency timers  
Note: You must configure alarm  
triggers locally on the MP  
modem using either 3G Watcher  
or an AT command.  
The low rate timer, alert rate timer, and GPS timer control the  
interval between reports from the MP modem.  
The low rate timer sets the interval at which reports are sent in  
the absence of any other trigger or timer. It is in minutes with a  
default of five minutes.  
Rev 1.5 Jul.08

MP880W Modem User Guide  
The fast rate timer only becomes active when an alarm  
condition is triggered by a rise or drop in the level of one of the  
digital I/O channels. The default for the fast rate timer is three  
seconds.  
Note: When the fast rate timer is set to 0, a single report is sent when  
an I/O alarm is triggered.  
If the GPS timer is set to a value other than 0, it controls the  
frequency of reports in the absence of any alarm or event  
triggers. (However, if the GPS timer is set to a longer interval  
than the low rate timer, the value for the low rate timer will  
determine report frequency.)

Note: The “MP 3G Modems  
TAIP Reference manual”  
(document #2130312) provides  
a description of the TAIP  
commands you can use. This is  
available at  
If the GPS timer is set to 0, the reporting interval is determined  
by the configuration of the GPS module. If the module is  
configured for TAIP, you can issue TAIP commands to change  
the interval. An advantage of configuring the report frequency  
with TAIP commands is that the interval between reports can  
be based on elapsed time and/or distance travelled.  
Information about GPS modules,  
including more documentation  
on TAIP commands, is available  
You can issue TAIP commands to the module locally through  
3G Watcher using the AT command AT!MPGPSCMD. They  
can also be sent remotely using MP Modem Manager. (See  
Reporting configurations set by sending TAIP commands will  
be erased if the MP modem is powered off unless the  
commands are included in the initialization strings for the MP  
modem. These are executed each time the MP modem is  
powered on. You can configure them locally by using 3G

AT!MPGPSINIT, or remotely with MP Modem Manager.

Note: More information on  
NMEA message standards is  
available at www.nmea.org.  
If the module is configured for NMEA, data is sent at five‐  
second intervals. (The interval cannot be changed when the  
module is configured for NMEA because NMEA is strictly a  
reporting protocol.)  
Monitoring and Tracking configuration  
You can use 3G Watcher to configure the MP modem to send  
MTP data to a network server:  
1. Select Tools > Options > MP > Monitor and Tracking and  
complete the appropriate fields.  
—or—  
1. Issue the AT command AT!MPMTCONF along with the  
required parameters.  
IP Addressing  
To send data to the MP modem, a host application on a  
network server requires the IP address of the MP modem.  
Service providers usually do not provide a static IP address to  
each device on the network. The IP address is dynamically  
assigned each time the MP modem registers on the network.  
This means that the host application must identify each MP  
modem by its Unique Mobile Device ID (discussed on page 70)  
and capture its IP address as it registers.  
If the MP modem has a public IP address, the host application  
can simply check the IP address on the incoming data packets  
to determine the IP address of the MP modem. However, if  
NAT (Network Address Translation) is in use, the IP address  
assigned to the MP modem is likely to be a private IP address.  
This may present problems, as discussed in the next section.

Sending Data to Your Network Application  
The problem created by Network Address  
Translation  
Note: A similar problem may  
occur if NAT is in use on your  
network. The host application  
may reside on a server that has  
a private IP address. You must  
configure the MP modem to  
send data to a server on your  
network with a public IP address,  
and configure the server to  
recognize the MTP data and  
route it appropriately.  
Many service providers use NAT (Network Address Trans‐  
lation) which effectively creates a firewall in front of the  
network. Inside the network, the service providers assign  
private IP addresses to registered devices, since public IP  
addresses are not needed to route data within the network.  
(This saves the service provider the expense of having a large  
pool of public IP addresses.) A public IP address is substituted  
for the private IP address when data packets pass through the  
gateway between the network and the Internet. This public IP  
address might be used on data transmissions from many  
different devices. Therefore, the network server is only aware  
of the substituted public IP address. If the server replies to this  
address, the network cannot identify the device for which the  
data was intended.  
Assume, for example, an MP modem is registered on a  
network. The MP modem is assigned a private IP address of  
10.95.236.1. When the MP modem sends MTP data to the  
network server, a public IP address of 24.7.6.30 is substituted at  
the gateway to the Internet. When the network server receives  
the data, the host application is only aware of the public IP  
address, 24.7.6.30. However, if the network server sends data  
back to the IP address 24.7.6.30, the network has no way of  
identifying the MP modem for which it is intended and is  
unable to route the data appropriately.

Figure 7-1: An MP modem connected to a network server. In this scenario, the  
IP address is “NAT’d” from 10.95.236.1 to 24.7.6.30. The network server is  
only aware of the address 24.7.6.30, but if it sends data to that address the  
network cannot route the data to the MP modem.

Solutions to the NAT problem  
develops client-server applica-  
tions that attempt to overcome  
the issues caused by NAT  
addressing by assigning its own  
consistent private IP addresses.  
This software offers a potential  
solution to NAT issues, but it is  
untested by Sierra Wireless, and  
Sierra Wireless does not provide  
support for it.  
If your service provider is using NAT, it is best to work with  
the provider in devising a solution. Some service providers  
offer, on request, accounts with public IP addresses. (There  
may be additional charges for this.)  
Another solution is to implement a frame relay connection  
between your network and your service providers network.  
The frame relay connection bypasses the address translation,  
and is a method of overcoming NAT issues encouraged by  
some service providers.

Retrieve the Unique Mobile  
Device ID  
In order to associate GPS and I/O data with a particular  
vehicle, you must create a database on your server that links  
each MP modems Unique Mobile Device ID to the vehicle in  
which it is installed. The Unique Mobile Device ID is a number  
derived from the IMEI (International Mobile Equipment  
Identity).  
Use the AT command ATI4 to obtain the Unique Mobile Device  
ID from each MP modem you deploy.  
You may also want to assign a device name to the MP modem  
that identifies the vehicle in which it is installed. You can  
assign this name locally using 3G Watcher or remotely using  
MP Modem Manager. The device name is included in the MTP  
data sent to the network server.

Note: Unauthorized modifica-  
tions or changes not expressly  
approved by Sierra Wireless,  
Inc. could void compliance with  
regulatory rules, and thereby  
your authority to use this  
equipment.  
To ensure that the MP modem meets Health Canadas Safety  
Code 6 requirements, a separation distance of at least 20 cm  
(8 inches) must be maintained between the modems antenna  
and the body of the user and any nearby persons at all times  
and in all applications and uses.  
Additionally, the maximum antenna gain in the PCS band,  
including cable loss, must not exceed 4 dBi, and in the Cellular  
band, must not exceed 5 dBi, to comply with Industry Canada  
and Health Canada regulations limiting both maximum RF  
output power and human exposure to RF radiation.  
For the MP 875W modem, the maximum gain for the AP  
antenna must not exceed 3 dBi, and the AP antenna must be at  
least 20 cm away from the Main RF antenna.  
U.S.A.  
To comply with FCC regulations limiting both maximum RF  
output power and human exposure to RF radiation, the  
maximum antenna gain, including cable loss, in the PCS band,  
must not exceed 4 dBi, and in the Cellular band, must not  
exceed 5 dBi.  
The Main RF antenna must be mounted such that there is a  
separation distance of at least 20 cm (8 inches) between the  
antenna and the body of the user or any nearby persons.  
For the MP 875W modem, the maximum gain for the AP  
antenna must not exceed 3 dBi, and the AP antenna must be  
professionally installed with a separation distance of at least 20  
cm away from the Main RF antenna, per FCC Part 15 require‐  
ments.
