Preface

Because of the nature of wireless communications, trans-

mission and reception of data can never be guaranteed. Data

may be delayed, corrupted (i.e., have errors) or be totally lost.

Although significant delays or losses of data are rare when

wireless devices such as the Sierra Wireless modem are used in

a normal manner with a well-constructed network, the Sierra

Wireless modem should not be used in situations where

failure to transmit or receive data could result in damage of

any kind to the user or any other party, including but not

limited to personal injury, death, or loss of property. Sierra

Wireless, accepts no responsibility for damages of any kind

resulting from delays or errors in data transmitted or received

using the Sierra Wireless modem, or for failure of the Sierra

Wireless modem to transmit or receive such data.

Do not operate the Sierra Wireless modem in areas where

blasting is in progress, where explosive atmospheres may be

present, near medical equipment, near life support equipment,

or any equipment which may be susceptible to any form of

radio interference. In such areas, the Sierra Wireless modem

MUST BE POWERED OFF. The Sierra Wireless modem can

transmit signals that could interfere with this equipment.

Do not operate the Sierra Wireless modem in any aircraft,

whether the aircraft is on the ground or in flight. In aircraft, the

Sierra Wireless modem MUST BE POWERED OFF. When

operating, the Sierra Wireless modem can transmit signals that

could interfere with various onboard systems.

Note: Some airlines may permit the use of cellular phones while the

aircraft is on the ground and the door is open. Sierra Wireless

modems may be used at this time.

The driver or operator of any vehicle should not operate a

computer or any other device connected to the Sierra Wireless

modem while in control of a vehicle. Doing so will detract

from the driver or operator's control and operation of that

vehicle. In some states and provinces, operating such commu-

nications devices while in control of a vehicle is an offence.

The information in this manual is subject to change without

notice and does not represent a commitment on the part of

Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES

• Introduction

• References

• Currency

• Document Structure

• Conventions

on the use of modems and AT

commands generally you may

Introduction

This reference details the Attention (AT) command set

supported by the MP 700 Series GPS rugged wireless modem.

You should be familiar with the use of AT commands with

standard wireline modems to use this document.

The Sierra Wireless GSM products present two methods of

controlling the modem: AT commands and CnS (Control and

Status) language. Some features or capabilities of the modem

require the use of CnS. This document presumes that the AT

interface is the only interface available to you; features

requiring CnS are not discussed.

References

This guide covers only the command set used by the

MP 700 Series GPS and does not deal with operational use.

Refer to the product documentation for instructions on using

your modem.

Not all commands include detailed descriptions. Commands

are implemented to be compliant with industry standards and

reference is often made to the following standards:

• IS-131 (Data Transmission Systems and Equipment -

Extensions to Serial Asynchronous dialing and Control)

• EIA/TIA-592 (Asynchronous Facsimile DCE Control

Standard, Service Class 2)

• EIA/TIA/IS-134 (Amendments to TIA-592 to Support T.30-

1993 (Facsimile protocol standard))

Electronic copies of these standards can be purchased at the

ANSI Electronic Standards Store at: webstore.ansi.org. ANSI

Customer Service will respond to inquiries about standards

Terminology and acronyms

This document makes wide use of acronyms that are in

common use in data communications and cellular technology.

Our Internet site provides a Glossary (document #2110032)

that may be helpful in understanding some acronyms and

terminology used in this guide.

Currency

This document is current with version R2_2_7ap of the

MP 750 GPS firmware and version R3_1_2ap of the

MP 775 GPS firmware.
