Introduction to the User's Guide Command Manual
1.1
Overview
AT commands are used for communication between the CM52 module and an application. All the AT
commands that are supported by CM52 are described in this AT command manual.
The CM52 Integrator's manual, which is provided with the CM52 module, contains information on the CM52
hardware, mechanics, Developer's Kit and how to get started in general.
This manual assumes that the CM52 module is connected properly as defined in the Integrator's manual and
is ready to start AT command communication.
1.2

This manual is divided into five chapters.
Chapter 1 provides a general overview of the AT command manual. This chapter contains abbreviations used
throughout the AT command manual and also contains information concerning Service and Support.

Chapter 4 contains all of the AT commands that are supported by the CM52 module. Each AT command has

commands in general.
Chapter 5 provides additional information about how to use the AT commands. This chapter contains user
