Part 1: Overview

Product Photo/Illustration

1. Introduction

1.1 Target Users

GM47 and GM48 modules are designed to be integrated into machine­to-machine or man-to-machine communications applications. They are intended to be used by manufacturers, system integrators, applications developers and developers of wireless communications equipment.

1.2 Prerequisites

It is assumed that the person integrating the GM47 or GM48 into an application has a basic understanding of the following:
• GSM networking;
• Wireless communication and antennas (aerials);
• AT commands;
• ITU-T standard V.24/V.28;
• Micro controllers and programming;
• Electronic hardware design.

1.3 Manual Structure

The manual is composed of four parts:
Part 1- Overview
This section provides a broad overview of the GM47/GM48 family and includes a list of abbreviations used in the manual.
Part 2 - Developer’s Kit
This section lists the contents of the whole development kit and provides the information to setup and use the equipment.
Part 3 - Integrating the Module
This section describes each of the signals available on the GM47/GM48 modules, along with mechanical information. The section also provides you with design guidelines and explains what is needed to commercialise an application from a regulatory point of view.

2. GM47/GM48 MODULES

2. GM47/GM48 Modules

2.1 About the GM47/GM48 Family

Two modules make up the family; GM47 and GM48, for use in the 900/1800MHz and 850/1900MHz GSM bands respectively.
Note! As the characteristics of the modules are quite similar, this manual only
refers to the GM48 where a difference exists; by default all other references are to the GM47.
The products belong to a new generation of Sony Ericsson modules, and are intended to be used in machine-to-machine applications and man-to­machine applications. They are used when there is a need to send and receive data (by SMS, CSD, HSCSD, or GPRS), and make voice calls over the GSM network.
GM47 modules are not “stand alone” devices; they are used as the engine in an application created by the customer. A typical application, involves a micro-controller and GM47 module, in which the micro­controller sends AT commands to the module via an RS232 communications link.

Figure 2.1 illustrates the main blocks of a wireless communication system using the GM47. It also shows the communication principles of the system. The definitions in the figure, as used elsewhere in this manual, are in accordance with the recommendations of GSM 07.07.
• The MS (mobile station) represents the GM47 module plus SIM card. The module excluding SIM card, is known as the ME (mobile equipment).
• The TE (terminal equipment) is a micro-controller (i.e., a computer) and is a part of the application.

GM47/GM48 INTEGRATOR’S MANUAL
In accordance with the recommendations of ITU-T (International Telecommunication Union - Telecommunications Standardisation Sector) V.24, the TE communicates with the MS over a serial interface.
The functions of the GM47 follow the recommendations provided by ETSI (European Telecommunications Standards Institute) and ITU-T.
ETSI specifies a set of AT commands for controlling the GSM element of the module; these commands are supplemented by Sony Ericsson specific commands.
To find out how to work with AT commands, see “Part 4: Using AT Commands”, page 79.
Figure 2.2 illustrates the interface between the module and the application. The entire System Connector Interface is described in detail in “System Connector Interface”, page 41

2.3.2 Short Message Service
The module supports the following SMS services:
• Sending; MO (mobile-originated) with both PDU (protocol data unit) and text mode supported.
• Receiving; MT (mobile-terminated) with both PDU and text mode supported.
• CBM (cell broadcast message); a service in which a message is sent to all subscribers located in one or more specific cells in the GSM network (for example, traffic reports).
• SMS STATUS REPORT according to GSM 03.40.
• SMS COMMAND according to GSM 03.40.
The maximum length of an SMS message is 160 characters when using 7-bit encoding. For 8-bit data, the maximum length is 140 characters. The module supports concatenated messages to extend this function. It is disabled if CNMI 3,2 is set (See “AT+CNMI New Message Indications to TE”, page 264).

2.3.3 Voice Calls
2.3.4 Data
The GM47 offers the capability of mobile originated and mobile terminated voice calls, as well as supporting emergency calls. Multi-party, call waiting and call deflection features are available. Some of these features are network-operator specific.
For the inter-connection of audio, the module offers both single ended and balanced analogue input and output lines. Direct interface to the digital PCM (pulse code modulation) bus used within the module is available, thus by-passing the internal analogue circuitry.
The module supports the following data protocols:
• GPRS (General Packet Radio Service) Modules are Class B terminals, which provide simultaneous activation and attachment of GPRS and GSM services. GM47 modules are GPRS 4+1 enabled devices, which are capable of transmitting in one timeslot per frame (up link), and receiving at a maximum of four timeslots per frame (down link).
• CSD (Circuit Switched Data) GM47 modules are capable of establishing a CSD communication at
9.6kbps.
18
• HSCSD (High Speed Circuit Switched Data). GM47 supports HSCSD communication, with one timeslot per frame capacity in the up link and two timeslots per frame capacity in the down link (2+1).

Part 2: Developer’s Kit

Product Photo/Illustration

1. Introduction

1.1 Overview

The developer’s kit is designed to get you started quickly. It contains all the hardware you will need to begin the development of an application. The only items you need to provide are; a computer or micro controller, a SIM card and network subscription, and a knowledge of programming with AT commands.
Note! Before connecting up and using the developer’s kit, we strongly
recommend you read “Part 3: Integrating the Module”, page 37 and all of this section. There are many switches, jumpers and connector options in the developer’s kit. A knowledge of the functionality of the GM47 module is therefore essential before you start altering the hardware settings.
The main hardware in the developer’s kit is a screened box, containing a board onto which you plug the GM47 module. Connectors, switches, jumpers and SIM card holder are provided to allow you to configure and access all the functions of the module.

1.3 General Functioning of the Kit

The following block diagrams are provided to help you understand the general principles of operation of the developer’s kit.
You have the following options as shown in Figure 1.1:
• Connect the GM47 internally, direct to J4 or position it externally and connect to J10 via a flat cable.
• Use the kit’s connectors to access and control the GM47 (all switches and jumpers in their default positions).
• Access and control the GM47 directly via J12 and a flat cable. This allows you to selectively bypass any circuits contained on the board, and test your own application.
