1: Introducing the MP Modem
???Software
Note: Do not connect the MP modem to a USB port on a computer before installing the software. (See ???Step
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 built???in 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 e???mail 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.
AirLink MP595 / MP595W Modem User Guide
About CDMA
The MP modem operates over
???
???High Speed Downlink Packet Access (HSDPA) ??? up to 3.6 megabits per second (Mbps)
a type of wireless network called Code Division Multiple Access (CDMA). CDMA Third Generation (3G) technology provides a variety of connectivity features, depending on your service provider and account:
???1x Evolution???Data Optimized Revision A
(1xEV???DO Rev. A) supports Internet connections with data rates up to 3.1 Megabits per second (Mbps) downlink from the network and 1.8 Mbps uplink to the network. Average data rates are 450???800 kilobits per second (kbps) downlink and 300???400 kbps uplink. Actual speed depends on network conditions.
???1xEV???DO Revision 0 (Rev. 0) supports Internet connections with data rates up to 2.4 Mbps downlink and 153 kbps uplink. Average data rates are
???1x supports Internet connections with data rates up to 153 kbps. Actual speed depends on the network condi??? tions.
???Circuit switched (dial???up) data, using the earlier CDMA IS???95 specification, supports data connections to any dial??? up service at rates up to 14.4 kbps.
The MP 595 modem is primarily designed to provide 1x or better data connections but it also allows for Circuit Switched Data (CSD) connections in areas that have CDMA IS???95 coverage but no 3G (1xEVDO or 1x) high??? speed packet service.
Quick Net Connect (QNC) provides a simplified way to dial into an Internet connection using CSD, assuming CSD is supported by your service provider.
Once a connection is established, you can open your browser and connect to web sites and access other Internet services such as e???mail.
CDMA account and coverage
You must set up an account with a CDMA service provider for each MP modem you install. After installing the MP modem software, you must configure it to use an account.
Introducing the MP Modem
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
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.
Account provisions Your account may restrict usage of certain networks or may limit your connection time or data transmission.
Supported CDMA radio frequencies
CDMA networks operate on two sets of radio frequency bands. The MP 595 modem is a dual???band product that operates on both bands:
???1900 MHz (also called the PCS, or Personal Communica??? tions Services, band)
???800 MHz (Cellular band)
Receive diversity
The MP 595 modem supports receive diversity for improved signal reception. Receive diversity uses two antennas to enhance the quality of the signal, but does not extend the MP modem???s coverage area.
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 dial???up modem.
AirLink MP595 / MP595W Modem User Guide
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.
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 Access Protocol (RNAP1) 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.
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 12.
Introducing the MP Modem

Plan your MP modem installation
This section guides you through the decisions you need to make before you begin the installation.
Where do you want to install your MP modem?
The MP modem can be installed in a vehicle or in an office. The same installation steps apply with the following exceptions:
???If you are installing the MP modem in a vehicle:
??Use the power harness to connect the MP modem to the vehicle battery.
??Decide how to set the ignition sense option for powering the MP modem on and off (that is, depending on the ignition switch wiring, the MP modem can be turned on when the engine is started, when the ignition is in accessory mode, or independently of the ignition).
???If you are installing the MP modem in an office, an AC/DC adapter is available.
What type of connection(s) do you plan to use?
The MP modem is capable of the following kinds of network connections:
???Serial
???USB
???Ethernet
???Wireless Access Point via IEEE 802.11b/g (MP 595W only)
Data transfer rates vary, depending on the network, but note that the highest data rate using a serial connection is
115.2 kbps.
Before deciding which network interface to use, you need to understand the advantages and disadvantages of each, and any other implications of using one interface over another.
Getting Started
The following table summarizes the advantages and disadvan??? tages of the various interfaces:
a.The wireless access point interface is only available with the MP 595.
b.Note: If you enable a wireless access point or Ethernet interface after a USB connection has already been established, the USB connection is disabled.
You can switch between interfaces after the modem is installed and configured, but before doing so, you need to understand the interface hierarchy.
If you switch from a serial interface to any other interface, the serial interface is disabled. If you switch from USB to either a Ethernet or wireless access point, the USB connection is lost. If you switch from Ethernet to wireless access point (MP 595W modem only), the Ethernet connection is disabled.
Watcher is available for all network interfaces except wireless access point.

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 return wire. (See ???Step
Note: Tighten cables connected to the MP modem by hand. Do not use tools.
Hardware and Software Installation
You can also use a ground screw on the connector panel of the MP modem. Use a 16???gauge wire if you choose to use a ground screw. A ground screw is not required as long as the power harness is properly grounded.

Ignition sense on/off wiring
This section only applies to installing an MP modem in a vehicle. If you are installing the MP modem in an office building, use the AC/DC adapter.
The MP modem???s 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.
Vehicle battery
Figure
???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), de???registering 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 vehicle???s 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.
???Accessory on. Connect the white ignition sense wire to the vehicle???s ignition switch so that the MP modem is powered

AirLink MP595 / MP595W Modem User Guide
Note: If you choose to install a separate switch, it must be connected to the white ignition sense wire, not the red battery wire, so that the MP modem can perform a controlled shutdown, as described on page 27.
Note: Ensure that all wires are correctly spliced or crimped. Improper grounding and wire connections may lead to equipment damage or safety hazards.
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
???Separately switched. Connect the white ignition sense 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. (See ???Ground the MP modem??? on page 22.) The ground wire in the MP modem power harness is not fused.
Power connections
Connecting the MP modem???s power wires properly is
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 heat???shrink the connection to re???insulate 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

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 vehicle??s 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.)
???Accessory on. The MP modem is powered when the ignition is switched to ??Accessories??. (This allows the MP modem to be powered when the engine is off.)
???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.)

NAT mode
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 drop???down 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=??x??, where ???x??? is the password. (Default password is MP3G, e.g. AT!MPCFGOPEN=??MP3G??)
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 device??s 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=??x??, where ???x??? is the password. (Default password is MP3G, e.g. AT!MPCFGOPEN=??MP3G??)
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.

7: Configuring the MP Modem to Report GPS and I/O Data
??? I/O device installation The MP modem is capable of reporting position and heading and configuration 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 8 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 Earth???s 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

AirLink MP595 / MP595W Modem User Guide
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 at www.sierrawireless.com. Information about Trimble GPS modules, including more documentation on TAIP commands, is available at www.trimble.com.
More information on NMEA message standards is available
at www.nmea.org.
GPS protocols and commands
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 pre???configured 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

I/O device installation and configuration
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 is required by the I/O device, and at the other end, the High 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.
AirLink MP595 / MP595W Modem User Guide
Note: No more than 36 VDC should be applied to any I/O pins.
Before using the digital input/output lines, you must configure them as inputs or outputs.
Connector pinouts
The MP modem???s I/O port is a female DB15HD connector with eight active I/O pins:
???Two (2) digital I/O pins.
???Two (2) digital input pins.
???Four (4) analog input pins.
There are also six reserved pins and one ground pin.

Port specifications
See ???I/O port characteristics??? on page 72 for the technical specifications of the I/O ports, including input voltages.
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
The pins report a logic high on an input of 3.45 VDC. An internal pull???up 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).
AirLink MP595 / MP595W Modem User Guide
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
The digital I/O ports provide open???collector 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 vehicle???s 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
The analog input ports use a 10???bit (1024???step) analog???to??? 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.
AirLink MP595 / MP595W Modem User Guide

The Analog Input window (Tools > Options > MP > Input/Output) is used to configure devices on the four analog inputs. Each tab corresponds to a pin:
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 10???bit (1024???step) resolution, so the raw value range is between 0 and 1023.

at www.trimble.com.
Sending Data to Your Network Application
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.
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 ???MP Modem Manager??? on page 11.)
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 Watcher (Tools > Options > GPS) or the AT command 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 66) 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.
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.
Sending Data to Your Network Application
The problem created by Network Address Translation
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.

Solutions to the NAT problem
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 provider???s network. The frame relay connection bypasses the address translation, and is a method of overcoming NAT issues encouraged by some service providers.

Frame relay
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 modem???s Unique Mobile Device ID to the vehicle in which it is installed. The Unique Mobile Device ID is a number derived from the ESN (Electronic Serial Number).
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.
