This document provides instructions for the Nokia 12 GSM module (hereafter Nokia 12 module) hardware integration. The document is intended to help the system integrator to integrate the Nokia 12 module into a remote end hardware application and to gain the necessary type approvals. The document describes the mechanical, electrical and radio frequency (RF) integration as well as antenna installation. In addition the document describes the technical characteristics of the Nokia 12 test board, and lists the certifications and technical requirements needed for type approval. The Nokia 12 module can be used in several applications due to its three different operating modes. Simple I/O applications can be easily implemented by using the Nokia 12 module in the User control mode that offers message personalising, secure messaging, and timing functionality for SMS controlled I/O applications. MECHANICAL INTEGRATION, The Nokia 12 module contains two holes for mounting screws. The screws can be used in mounting, but are not compulsory. The Nokia 12 module has been tested according to the automotive standard DIN 72300-3 (although not in various temperatures), and it can be integrated into various applications without the screws. Timing of clock and transmission signals, PCM timing diagram. RF AND ANTENNA INTEGRATION, An adapter cable between the MMCX connector and the antenna may be needed. Suitable connectors and cables are available, for example, from Amphenol, TYCO, and IMS Connector Systems. The Nokia 12 module is certified with a Smarteq dual-band antenna (art no: 1140.26 for 900/1800MHz and 1140.27 for 850/1900MHz). Suitable antennas are available, for example, from Smarteq and Hirschmann.
