1. INTRODUCTION

Scope

This document covers the more significant standard and proprietary AT commands provided by Telit's modules. Several module features are described and for each one of them the related AT commands are explained through examples. This document is not an exhaustive description of the AT commands implemented on the Telit's modules series, its target is only to give you an entry point to the AT commands world.

Audience

The present User Guide is addressed to users that need to learn and use quickly standard and proprietary AT commands. The reader can learn the use of the AT commands through simple examples shown in the document, and then deepen the interested AT commands reading the documents [1]/[17] in accordance with the used module.

2. OVERVIEW

Before dealing with the technical characteristics of the CMUX Standard Protocol [1] provided by the GE310-GNSS Module and the setting up and use of the Telit Serial Port MUX tool running on DTE (PC-Windows), it is useful to show how the two software components can be used together and which advantages they give. The GE310 shows three virtual connections (VC1, VC2, VC3) which are running on a unique physical serial line (COM1/ASC0); the Module has entered the Multiplexed Mode.

The three different Applications running on DTE are tied, via the virtual connections, to three Access Points in order to communicate with three different Services provided by the Telit Module.

The main steps to enter the Multiplexed mode are:

• Telit Module and DTE are physical connected via ASC0/COM1 serial ports, and both are

powered on;

• Run the Telit Serial Port MUX tool on DTE, refer to chapter 6;

• On DTE start, for example, three Hyper Terminals connected to three virtual ports

provided by the Telit tool, e.g. COM3, COM4, COM5.

• Now the Hyper Terminals can send and receive data from the Module on three

independent Virtual Channels by means of the Multiplexer Protocol implemented by the Telit Tool.

Tab 1 summarizes the VSD Configuration of GE310

Legend:

“ASC0/VCx”: Virtual Connection (channels) that must be used to reach the Access Point

indicated on the top of the column. The user can use one or more Access Points.

Tab 1: CMUX vs. Access Points

NOTE

with the term “instance” is intended an AT Commands Parser. TELIT modules provide three logically independent AT Commands Parsers. Any instance is connected to an Access Point. In general, the Access Point is the connection between the communication path and the Service offered by the module.
