Commands Reference Guide.

Chapter 2 – Setup and Configuration

3. Establish a Wireless Account

Obtain a wireless account through a Wireless Service Provider. This will allow you to use the service
provider's network; for example, Cingular, Sprint, and Verizon.

Cingular and Sprint: Contact Multi-Tech, a certified national activation agent for Cingular and Sprint to

set up one of these accounts.

Verizon and Others: For Verizon and other accounts, contact their activation agents directly.

Activations Instructions: See the Cingular, Sprint, Verizon, and general Customer Activation

Customer Notices included with your modem for a list of the information you must give to the activation
agent. You will receive, depending upon your provider, one or two phone numbers and a service
programming code or lock code. Write these numbers down as you will have to use them to configure
the wireless modem.

If you have any questions or want to set up your account, contact Multi-Tech Systems, Inc. at:

800-972-2439 or 763-717-5863.

4. Establish Internet Access

Internet Access Using:

• GSM with GPRS

• CDMA 1x Data

A single DUN number is generally used by all of a wireless provider’s subscribers throughout its
area of coverage – regional, nationwide, continental, etc. Rather than being a literal phone
directory number, as in conventional DUN, this is a code that gives the modem Internet access.

Internet Access Using:

• GSM without GPRS

• CDMA Point-to-Point Data

A circuit-switched data connection is used. Use the dial-up-network (DUN) to make a
conventional V.32 modem connection to any terminating modem at the other end. The phone
number specified in the DUN can be one supplied by the wireless service provider or another
phone number related to a different dialup modem service (e.g., a dialup modem service phone
number from any commercial or private dialup network).

Parity: N
Stop: 1
Flow-Control: None

• Press the Enter key three times to get to the Login prompt.

• At the Login prompt, type admin.

• At the Password prompt, type admin.

Important: User name and password are case sensitive. They must be typed in lowercase letters.

• Then type dialout serial s1 to start a dialout session. Dialout serial s1 is used to initiate a dialout

session to the modem. You can now enter AT commands to test your modem.

6. Using AT Commands to Test Your Modem

1. Check the signal quality.

This command determines the received signal strength indication (<rssi>)

• Type AT+CSQ

Modem responds with the received signal strength (<rssi>).
Response 0 means -113 dBm or less
Response 1 means -111 dBm
Response 2 to 30 means -109 to -53 dBm
Response 31 means -51 dBm or greater
Response 99 means not known or detectable

2. Check the identity of the modem.

Use this command: ATI (AT is followed by the capital letter i).

• Type ATI0 (The command ends in a zero).

Manufacturing data displays: Wavecom Modem 800 1900

• Type ATI3

Software version displays. Ex: S/W VER: xxxxx

• Type ATI6

Capability data displays. Ex: +CGSM, +CIS707, ...

3. Check the network registration and roaming status.

• Type AT+CREG?

The modem will respond in one of the following ways:
+CREG: 0,0 (this tells you the modem is not registered on any network)
+CREG: 0,1 (this tells you the modem is registered on the home network)
+CREG: 0,5 (this tells you the modem is registered on a network but it is roaming)

serial data that cannot be read when using Windows Terminal or PROCOMM. To view the output of the
TSIP protocol in text format, use the iQ_CHAT or the iQ_Monitor program. These programs are
included on the CD-ROM as part of the MultiModem GPS Developer’s Kit.

About iQ_Monitor and iQ_Chat Utilities

The iQ_Monitor.exe and iQ_Chat.exe files plus a Developer’s Guide entitled
Developing a Software Interface for the GPS Module in the Multi-Tech MultiModem
are included on the CD as part of the MultiModem Developer’s Kit.

iQ_Monitor

iQ_Monitor is used to verify GPS is functioning. The Developer Guide explains
how to setup and use this utility.

It is a 32-bit Windows application that interfaces with a TSIP-speaking receiver
through the GPS serial port. The program accepts TSIP reports and displays
these fields in a window:

Position, Velocity, Time, Receiver Status, and Satellite Track Status.

The program allows you to exercise some basic TSIP commands and can also
log a TSIP report in binary format for later translation.

Pin 5 = GND

iQ_Chat

iQ_Chat is a 16-bit DOS-based application that interfaces with the GPS receiver
through a serial port. It allows you to exercise TSIP commands, configure the
GPS receiver for NMEA or TAIP, and view NMEA or TAIP output. It also logs a
TSIP report in binary format.

Chapter 2 – Setup and Configuration

2. Hardware Setup

1. Using an RS-232 cable, connect a workstation to the GPS connector on the MultiModem.

2. Attach both antennas (included in your ship kit). The GPS antenna is a 50 ohm SMA antenna. The

GSM/ CDMA antenna is a standard SMA antenna.

3. Plug one end of the power cord into the device and the other end into a live power outlet. The PWR

LED lights up.

Warning: Do not connect your wireless modem directly to a vehicle’s battery

for your power source. Doing so may cause power spikes. If you wish to use
the battery as a power source, add a filtering device to the DC input.

3. Verify the GPS Connection

The workstation should be running a utility, such as iQ_Monitor, to monitor GPS satellite signals.
iQ_Monitor is included on the product CD with the MultiModem Developer’s Kit.

Chapter 3 – Setup/Configuration

Examples

Application Example 1

In this example, the GPS side of the MultiModem is monitoring GPS locations and the wireless modem side of
the MultiModem is waiting for incoming data.

A portable workstation, such as a laptop or handheld PC, is connected to this wireless modem to both serial
ports – the GSM/CDMA port and the GPS port.

1. Using an RS-232 cable, connect the GPS connector jack to portable PC’s serial port.

2. Using an RS-232 cable, connect the GSM/CDMA jack to the PC’s other serial port.

3. Attach both antennas (the GPS antenna and the GSM/ CDMA antenna).

4. Set both the S1 and S2 switches up (the default). If you have not changed the switches previously,

then they will be in the default position. Note that the switches are located behind a cover plate on
the connector side of the modem. The cover plate can be removed when you need to change the
switch settings.

5. Connect to a power source; for example, to a cigarette outlet on a vehicle.

6. Run your software application that reads GPS data from the GPS serial port. The wireless modem

is available to the portable PC for transferring data.

7. Your central tracking station can then retrieve the data wirelessly from your CDMA, GPRS, or

EDGE network provider connection.

Chapter 3 – Setup/Configuration Examples

Application Example 2

This example shows the MultiModem GRPS Wireless Modem with GPS
mounted in a truck that can be tracked by a GPS satellite.

This configuration shows a MultiModem located in a vehicle and not connected to a portable PC. The
MultiModem in this example simply reads the GPS data as it is sent from GPS satellite, and then it broadcasts
the data to your central tracking system by way of your CDMA, GPRS, or EDGE network provider connection.

Note that in this example, you cannot configure the GPS; you can only receive data from port 1 of the GPS.

1. Mount the MultiModem in a vehicle.

2. Attach both antennas (the GPS antenna and the GSM/ CDMA antenna).

3. Verify the S1 switch up (the default).

4. Set the S2 switch down. This allows data from the GPS port 1 to flow to the wireless modem side

of the MultiModem. Then, when you call into this modem from a remote location, the GPS data is
displayed on the remotely located workstation’s screen. Note that the workstation can be a laptop
or a handheld device.

5. Connect to a power source; for example, to a cigarette outlet on a vehicle.

6. Your central tracking station can then retrieve the data wirelessly from your CDMA, GPRS, or

EDGE network provider connection.

The Antenna

The antenna sub-system and integration in the application is a major issue: Choice of antenna (type, length,
performances, thermal resistance, etc.) These elements could affect GSM performances such as sensitivity and
emitted power.

EDGE, GSM, and CDMA Antenna

The integrated modem antenna connector is a SMA connector. The SMA connector incorporates a 'Screw-on' action
in order to make the connection easier while providing an excellent RF performance. An additional advantage is its
small physical size, which is 50% of the standard MCX connector.
This type of connector is suitable for the standard ranges of flexible and semi-rigid cables. The characteristic
impedance of the MMCX coaxial connector is 50 ohm. The antenna manufacturer must guarantee that the antenna
will be working according to the radio characteristics presented in the table below.
