1.4. Document Structure
This document focuses on the operational view. The hardware view is covered in a reference
section at the end.
There is a Getting Started chapter in this section intended to help you quickly get the toolkit
components connected and communicating.
The operational view follows, starting with the basics of the Watcher and WirelessExpert™
software provided with the toolkit. Important background on the modem basics, including
terminology used in this guide, starts you into the operational elements of getting your modem
configured and operating. There are separate chapters covering modem operation in each of the
three possible modes with sample configurations.
The hardware view is covered in two chapters. The first describes the modem product
descriptions including the hardware integration issues of each of the modems. The second is a
reference to the Multipurpose Interface Board (MIB) used to test and configure the modem during
product development.
1.4.1. Modem Operations
The various modes, states, and conditions the modem can be placed in are described in the chapter
on Basic Modem Operations. That chapter also discusses the communication interface between
the host (DTE) and the modem.
The types of protocols supported in each mode are described but examples of configuring the
modem will be found in the chapters on operations for each specific mode.
1.5. Conventions Used in this Reference
Hardware signals are named with a convention of:
NAME active high (5 Volts)
\NAME active low (0 Volts)
Result Code – This is a numeric or text code that is returned after all commands (except resets).
Response – This term indicates a response from the modem which is issued prior to a return code.
Reading registers or issuing commands that report information will provide a response followed
by a return code unless the command generates an error.
Hexadecimal values are shown with a prefix of 0x, i.e. in the form 0x3F.
Character codes which are described with words or standard abbreviations are shown within angle
brackets: such as <CR> for Carriage Return and <space> for a blank space character.
AT Command and register syntax is noted using an alternate font:
AT+WS46=4
