1. About this Guide
1.1. Introduction
This guide is intended to assist both hardware integrators and application software developers with
the setup, installation, testing, and design of applications for the Sierra Wireless SB300 Series
OEM modems. You should be familiar with the use of modems, communication media (PSTN
and Cellular), protocols, and the use of AT commands.
This guide describes the full feature set of the entire SB300 series, so some sections may not apply
to the particular model you are using. Consult the Product Descriptions for a summary of the
features available on each product.
1.1.1. Getting Started
Chapter 2 covers the setup up of the OEM Developer’s Toolkit (the toolkit) and establishing host
communication with the modem. If you have any uncertainties about the Multipurpose Interface
Board (MIB), the modem, or the connectors, consult the Hardware View reference chapters.
1.1.2. Operational View
The main body of this document covers the operational issues of the SB300 Series modems.
Installation and use of the application software Watcher and WirelessExpert™ is covered. These
programs are designed to manage use of the modem in a Microsoft Windows
®
95/98/NT
environment without the need for further interface programming.
If custom applications are required, additional information is provided covering connection issues
and tips for writing applications. A complete reference to the available modem commands is in a
separate document (2110031 included with the toolkit).
Use of a terminal application for initial setup and testing of a modem may be required. Terminal
emulation software is not provided nor described in this guide.
1.1.3. Hardware View
This guide provides product descriptions of the SB300 Series OEM modems including the
information needed for the physical integration of the modems.
A full description of the Multipurpose Interface Board provided with the OEM Developer’s
Toolkit is also included in this guide.
