Preface
Scope of this Manual
Data terminal equipment (DTE) OEM teams are often pulled together quickly from other work
groups.
For this reason, OEM team members often need advice about how to best sustain a concerted
design
And development effort. The goal of this guide is to assist the team to successfully produce a
ireless
Product that integrates a Motorola c18 wireless modem.
Who Should Use This Manual
Our readers are intended to be data terminal equipment (DTE) OEM integration team members.
Teams historically consist of representative from the disciplines of hardware, software, and RF
engineering.
Disclaimer
This guide provides advice and guidelines to OEM teams. Responsibility for 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
specification.
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 c18 modem is not a stand alone transceiver but is an integrated
module, the c18 cannot be tested by itself for EME certification. It is, however, the integrator
responsibility to have the completed device tested for EME certification.
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 c18 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 c18 must be operated at the voltages described in the technical documentation.
3
Developers Manual
Abc
2. The c18 must not be mechanically nor electrically changed. Usage of connectors should follow
the
guidance of the technical documentation.
3. The c18 has been designed the meet the EMC requirements of ETS 300 342.
4. When integrating the c18 into a system, Motorola recommends testing the system to
ETS300342-1.
5. The c18 meets the safety requirements of EN60950.
6. Systems using the c18 will be subject to mandatory EMC testing under directive 89/336/EEC
and
only optional (see 3.) Other directives like the LVD directive 73/23/EEC might also be applicable
to a
system using c18.

User Operation
Do not operate your telephone when a person is within 8 inches (20 centimeters) of the antenna.
A person or object within 8 inches (20 centimeters) of the antenna could impair call quality and
may cause the phone to
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 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 following requirements must be met.
Antenna Installation
1. A minimum separation distance of 20 cm must be maintained between the antenna and all persons.
2. The transmitter effective radiated power 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 6.1 dBi.
operate at a higher power level than necessary and expose that person

P500 – Power Supply connector intended for use with laboratory power supplies. Power supply should
be capable of providing 4.5V dc and continuous current of at least 1.5A. Protection circuitry generates
voltage drop of approximately 0.5V at full load (maximum c18 power), therefore providing c18
module with nominal 4.0V.
Supply for active GPS antenna should be connected to pin #1 of this connector for c18 models with
active GPS antenna capability. Voltage and current supply requirements for power supply for active
GPS antenna depend on the type of the active antenna (typically 3 or 5V, with currents of up to tens
of mA).

Switch S500 serves as the Developer kit ON/OFF switch. In its OFF position, supply voltage to c18
module and all Developer board circuitry is disconnected. In its ON position voltage supply is routed
to the Developer board circuitry and c18.
Note that GPS_ANT_POWER is not influenced by S500 – active antenna supply is directly routed to
c18 interface connector.
NOTE: Do not apply both power supply connectors simultaneously! Damage to the kit
and/or power supplies might occur. If Power for active GPS antenna is needed, use P500
only.

Two different modes of operation are supported for this input. In the first mode, it can be directly
routed to the c18 interface connector, via 1uF capacitor. In the other mode, this input is routed
through a preamplifier on Developer’s Board. In the preamplifier mode, a DC bias can be added to
the audio input, thus making an interface capable of accommodating different active microphones
(typically found in car-kit like applications). Preamplifier gain is set to 9.1.
Behavior of this input is defined by P401, P402, P406 and P403 jumper position:
