1. INTRODUCTION

The Nokia 12 GSM connectivity module has been designed for M2M (machine-to-machine) applications and other wireless solutions. There are two versions of the Nokia 12:

• RX-2 dual-band GSM device supporting EDGE, GPRS, HSCSD, CSD, and SMS in EGSM 900/GSM 1800 MHz bands

• RX-9 dual band GSM device supporting EDGE, GPRS, CSD, SMS in GSM 850/GSM 1900 MHZ bands.

The Nokia 12 can be used in several applications due to its three different operating modes. Simple I/O applications can be easily implemented using the Nokia 12 in the User control mode that offers message personalising, secure messaging, and timing functionality for SMS controlled I/O applications. Additional intelligence for I/O applications can easily be implemented with Java. In the AT command mode, the Nokia 12 can be used as a GSM modem that supports Java for creating extra intelligence. In modem use, all supported bearers are available, subject to network support.

The Nokia 12 is compatible with the Nokia M2M Platform. In the M2M system mode, the Nokia 12 communicates with the server application through the Nokia M2M Gateway, and all the compatible features of the Nokia 12 are available for developing a wide range of M2M applications.

In addition to these operating modes, the Nokia 12 has an integrated TCP/IP stack which enables direct GPRS or GSM data connection between a remote end application and a server application. Due to the integrated TCP/IP stack, the HTTP and Socket APIs of the Nokia 12 are available for application development.

In addition to the bearers and operating modes listed above, the Nokia 12 supports several Java APIs, location service for external GPS module integration, reliability features like AutoPIN, GSM encryption and security codes, reset mechanism and Nokia M2M Platform authentication. Java™ technology support enables upgrading the application software over the air, and smart messaging makes the installation flexible. GSM phase 2+ supplementary services enable developing voice applications.

Note that all data bearers as well as TCP/IP are dependent on network support.

This document describes the main characteristics of the Nokia 12 and is intended to help the system integrator both integrate the Nokia 12 in an application and gain the correct approvals. Basic product information is available in Ref 1.

2. MECHANICAL INTEGRATION

The Nokia 12 contains two holes for mounting screws. The screws can be used in mounting, but are not compulsory. The Nokia 12 has been tested according to the automotive standard DIN 72300-3. The module can be assembled to various applications without the screws.

3. ELECTRICAL INTEGRATION

3.1 M2M SYSTEM CONNECTOR

All signals are routed through the M2M system connector, except the antenna, which is routed through the MMCX RF connector.

The M2M system connector is a 60-pin (2 rows, 30 per row) 1.27 mm pitch pin header connector. It has a frame that helps in the assembly and also holds the Nokia 12 firmly in position.

The possible mating connector is described in Table 1.
