1. PREFACE
DRAFT 1 (31.3.03)
1.1 SCOPE 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.
1.2 WHO 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.
1.3 DISCLAIMER
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.
1.4 REGULATORY 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.
1.5 REGULATORY 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 1
Preface
DRAFT 1 (31.3.03)
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.
1.6 SAFETY
1.6.1 User 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.
1.6.2 Antenna 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.

3.1.3 Quick Start
This section describes a series of Quick Start procedures for first-time use of the Developer Board.
3.1.3.1 g20 Connection
Open the top cover of the Developer Board and insert the g20 in its designated position. The g20 should connect to the 70-pin
connector, labeled UUT (P1), and its holes should be aligned with the spacers on the Developer Board.
Fasten the g20 to the Developer Board spacers using two M2x0.4x6 mm screws provided with the kit. PLEASE PROVIDE
GRAPHIC.

DRAFT 1 (31.3.03)
3.1.3.3 Power 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
3.1.3.4 Serial 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
3.1.3.5 Audio 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.
3.1.3.6 SIM 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
3.1.3.7 Default 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.
3.1.3.8 Operating 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.

Developer Board and Interfaces Description
DRAFT 1 (31.3.03)
3.2 COMMUNICATIONS 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.
3.2.1 RS232
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.

3.2.2 USB
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.

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.

3.2.3 SPI
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 11
Developer Board and Interfaces Description
DRAFT 1 (31.3.03)
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.
