Overview

Product Photo/Illustration

1. Introduction

1.1 Target Users

The GR47 and GR48 radio devices are designed to be integrated into machine-to-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 radio device 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 three parts:

Part 1- Overview

This section provides a broad overview of the GR47/GR48 family and includes a list of abbreviations used in the manual.

Part 2 - Integrating the Radio Device

This section describes each of the signals available on the GR47/GR48 radio devices, 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.

Part 3 - Developer’s Kit

This section lists the contents of the Developer’s Kit and provides the information to setup and use the equipment.

2. GR47/GR48 Radio Devices

2.1 About the GR47/GR48 Family

Two radio devices make up the family; GR47 and GR48, for use in the

E-GSM900/GSM1800 and GSM850/GSM1900 bands respectively.

1RWH This manual refers to the GR47 and GR48 as radio devices. If there is a

difference in the functionality of the radio devices the GR47 and GR48 information will be listed separately.

The products belong to a new generation of Sony Ericsson radio devices, and are intended to be used in machine-to-machine applications and manto-machine 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.

The radio devices can either have applications embedded onto them or they can be used as the engine in an application created by the customer. The radio device can send and receive data when a script is executed, the script can be run internally from the radio device itself or from a micro-controller. A typical application, involves a micro-controller and a radio device, in which the micro-controller sends AT commands to the radio device via an RS232 communications link.

2.2 Radio Devices in a Communication System

Figures 2.1 and 2.2 illustrate the main blocks of a wireless communication system using the radio device. Figure 2.1 shows the communication system when the script is embedded on the radio device and figure 2.2 shows the communication system when a micro-controller is used. They also show the communication principles of the system and the interface between the radio device and the application. The definitions in the figures, as used elsewhere in this manual, are in accordance with the recommendations of GSM 07.07.

• The MS (mobile station) represents the radio device and SIM card. The radio device excluding SIM card, is known as the ME (mobile equipment).

• The DTE (data terminal equipment) is the controlling application. This can be either an external host or an internal embedded application.

• The DCE (data circuit terminating equipment) is the serial communication interface of the MS.

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 radio device 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 radio device; these commands are supplemented by Sony Ericsson specific commands.

To find out how to work with AT commands, see the AT Commands Manual.

2.3 Features

The radio device performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI and ITU-T. The functions of the radio device are implemented by issuing AT commands over a serial interface.

5. System Connector Interface

5.1 Overview

Electrical connections to the radio device (except the antenna), are made through the System Connector Interface. The system connector is a 60-pin, standard 0.05 in (1.27 mm) pitch device.

The system connector allows both board-to-board and board-to-cable connections to be made. Use a board-board connector to connect the radio device directly to a PCB, and a board-cable connector to connect the radio device via a cable.

Figure 5.1 below shows the numbering of the connector pins.

A ground connection is provided at the mounting hole next to the RF connector on the radio device as shown below. Connect this ground point to the DGND pins of the radio device by the shortest, low-impedance path possible. The purpose of this connection is to allow any antenna ESD strikes to bypass the radio device’s internal ground path.

Power is supplied to the radio device VCC pins, from an external source.

LZT 123 7589 R1A

5. SYSTEM CONNECTOR INTERFACE

Connect all VCC pins together in your application in order to carry the current drawn by the radio device.

The electrical characteristics for VCC are shown in the table below.

1RWH The radio device has no internal capacitance to supply the large current

peaks during GSM burst transmission. We recommend you follow these general guidelines:

• Fit a low ESR electrolytic capacitor close to the radio device: > 1,000 µF;

< 100 m

• Make sure power supply to radio device line resistance is < 200 m

5.5 Battery Charging Input (CHG_IN)

For battery powered applications, the radio device has a connection to aid and support battery charging. The typical design where this may be applicable is to power the radio device directly from a battery source connected to VCC (pins 1, 3, 5, 7, 9) and to provide a 5V dc power source (600mA max) to the CHG_IN connection (pin 11). The radio device can control an internal switching FET which creates a charging pathway to the battery. While power is provided at CHG_IN, the battery charge can be maintained. If the power should fail or be removed at CHG_IN, the application will be supported by the battery alone. When CHG_IN voltage returns, the battery charging and maintenance will commence once more.

…

Safety considerations should be taken into account. For example, monitoring the temperature of the battery. If the temperature of the battery exceeds its specification limits, battery charging must be stopped immediately. If the battery temperature continues to rise the application should be suspended or the battery disconnected.

1RWH When charging Lithium batteries, the battery pack must have an internal

protection circuit in accordance with the manufacturer’s instructions.
