1. PREFACE

1.1SCOPE OF THIS MANUAL

This manual introduces the g20 Developer's Kit, and describes the technical details required by the data terminal equipment (DTE) team to successfully integrate the Motorola g20 cellular engine into an original equipment manufacturer (OEM) wireless host device. With the help of this manual, the DTE team can use the Developer's Kit to conduct a full series of test and evaluation procedures on the g20, as well as perform application development.

We at Motorola want to make this guide as helpful as possible. Keep us informed of your comments and suggestions for improvements.

You can reach us by email: GSM support-BSH015@email.mot.com.

1.2WHO SHOULD USE THIS MANUAL

This manual is intended for all members of the DTE OEM integration team who will use the g20 Developer’s Kit, including representatives from hardware, software and RF engineering disciplines.

1.3DISCLAIMER

This guide provides advice and guidelines to OEM teams. Responsibility regarding how the information is used lies entirely with the OEM. Statements indicating support provided by, or offered by, Motorola are subject to change at any time.

Motorola reserves the right to make any changes to this manual.

1.4REGULATORY REQUIREMENTS

The Federal Communications Commission (FCC) requires application for certification of digital devices in accordance with CFR Title 47, Part 2 and Part 15. This includes Electromagnetic Energy Exposure (EME) testing. As the g20 modem is not a standalone transceiver but is an integrated module, the g20 cannot be tested by itself for EME certification. It is, however, the integrator’s responsibility to have the completed device tested for EME certification.

1.5REGULATORY STATEMENT

The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating the g20 module. Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel, and to incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Motorola assumes no liability for customer failure to comply with these precautions.

1.The g20 must be operated at the voltages described in the technical documentation.

2.The g20 must not be mechanically nor electrically changed. Use of connectors should follow the guidance of the technical documentation.

3.The g20 is designed the meet the EMC requirements of ETS 300 342.

98-08901C64-O

DRAFT 1 (31.3.03)

Preface

4.When integrating the g20 into a system, Motorola recommends testing the system to ETS300342-1.

5.The g20 meets the safety requirements of EN60950.

6.Systems using the g20 are subject to mandatory EMC testing under directive 89/336/EEC (see item 3 above). Other directives, such as the LVD directive 73/23/EE, may also apply to a system using the g20 module.

1.6SAFETY

1.6.1User Operation

Do not operate your telephone when a person is within eight inches (20 centimeters) of the antenna. A person or object within eight inches (20 centimeters) of the antenna could impair call quality and may cause the phone to operate at a higher power level than necessary, as well as expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines.

IMPORTANT: The telephone must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting devices.

IMPORTANT: To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile transmitters, the requirements described in the section that follows must be met.

1.6.2Antenna Installation

•A minimum separation distance of 20 cm must be maintained between the antenna and all persons.

•The effective radiated power of the transmitter must be less than 1.5 Watts ERP (2.45 Watts or 33.9 dBm EIRP). This requires that the combination of antenna gain and feed line loss does not exceed 11 dBi.

Developer Board and Interfaces Description

3.1.3.3Power Connection

The Developer Board can be powered using either a wall-mounted adapter, a DC power supply or a battery cell.

Only the adapter option is covered in this section. See “Power Connections” on page 15., when using other power methods.

Note

Connect the adapter to the wall outlet and to the Developer Board adapter connector (J230) labeled Adapter.

The power source selection jumper, labeled Source, must be in the correct position for adapter operation (pins 1-2 shorted).

Note

3.1.3.4Serial Connection

The USB and RS232 serial interfaces are available for PC communications. If a PC connection is required, connect either an RS232 cable with a male D-Type connector to the labeled UART1 connector, or a USB cable with a B-Type connector to the labeled USB connector.

When using a USB interface, be sure the USB jumper (P300) position reflects the g20 version being used. See “USB” on page 11..

Note

3.1.3.5Audio Connection

The Developer Board has several available audio configurations:

•Hands-free audio using the speaker and microphone

•Digital PCM audio

•Personal headset audio

Only the headset audio option is covered in this section. See “Audio Interface” on page 21. when using other audio options.

Note

Connect the supplied headset to the headset connector (J440) labeled Headset.

3.1.3.6SIM Card Connection

Insert a SIM card into the SIM tray (J100).

When using a SIM card, be sure the SIM jumper (P110) position reflects the g20 version being used. See “SIM Card” on page 23. for more details.

Note

3.1.3.7Default Switches and Jumper Settings

The Developer Board jumpers and switches are initially configured to comply with this Quick Start operation mode. If different settings are necessary, refer to the relevant section for details about the required switch or jumper settings.

3.1.3.8Operating the g20

After completing the initial setup, turn on the Developer Board power by switching the power switch (S200) to its on position, and turn on the g20 by depressing the on/off switch (S110) or by depressing the on/off button on the keypad.

DRAFT 1 (31.3.03)

Developer Board and Interfaces Description

3.2COMMUNICATIONS INTERFACES

The g20 Developer Board includes three different serial interfaces:

•RS232

•USB

•SPI

The RS232 and USB ports are multiplexed within the g20, and therefore cannot be operated simultaneously. Their default connection is RS232. The SPI interface is used for debugging.

Each of these serial interfaces is described in the sections that follow.

3.2.1RS232

The RS232 serial port is the primary interface to the g20 UUT via the J350 connector. This port is denoted by the RS232-1 marking beside the 9-pin, D-type connector.

The UUT RS232 signals are active-low CMOS-level signals (0-2.7 V), which are converted by the Developer Board to standard RS232 levels for PC communications.

Developer Board and Interfaces Description

3.2.2USB

The USB interface operates according to the g20 UUT configuration. The Developer Board has a complete USB transceiver circuit to support USB communications for g20 units that do not include a USB driver of their own. The Developer Board USB interface can be overridden manually when using a g20 unit that does include its own USB driver interface.

Pin #	Description

4	Ground

The USB jumper (P300) located next to the USB connector selects between the Developer Board USB interface and the UUT USB interface. By changing the jumper position, the USB_VBUS signal is diverted to the selected driver (in the g20 or on the Developer Board) and operates it.

3.2.3SPI

The Developer Board includes a secondary 4-wire RS232 interface, which is connected to the g20 internal SPI bus through the J500 connector. This interface is used to debug applications. This port is denoted by the RS232-2 label next to the 9-pin D-type connector.

98-08901C64-O

DRAFT 1 (31.3.03)

Developer Board and Interfaces Description

On the Developer Board, the g20 SPI interface is converted to standard RS232 signals for PC communications. The conversion process uses the RS232 interface as a second slave on the internal g20 SPI bus, and communicates with it as such. SPI read and write operations are performed normally, using the CS and IRQ signals provided by the conversion circuit. The IRQ signal is connected to a g20 IRQ pin.
