GR47

The picture below presents the conceptual mechanical design of the GR47/48. The GR47/GR48 are protected with AISI 304 Stainless Steel covers suitable to fulfil the environmental and EMC requirements. Dimensions, the position of the different connectors and mounting holes are shown in figure 2.2.

The GR47 belongs to a new generation of Sony Ericsson Mobile Communications GSM modules. This document describes the main characteristics and functionality of the GR47. The GR47 should be handled like any mobile station. In the Integrators' Manual you will find more information about safety and product care. In the Technical Data chapter in this document the environmental and electrical limits are specified. Never exceed these limits to ensure the module is not damaged.

Features of the GR47 are:(1)07.10 multiplexing; (2)GPS interoperability; (3)SIM application toolkit, class 2 release 96 compliant; (4)embedded application; (5)on board TCP/IP stack.A typical system is one where a micro controller in an external application communicates with the module over its serial interface.The micro controller will control the module, via the supported set of AT commands. It is assumed that the system integrators have a high technical knowledge and the ability to integrate the module into a system.

The absolute maximum ratings of the GR47 can be summarized as:(1)SIM card interface (external only):3V or 5V;(2)storage temperature:-40 to 85;(3)operating temperature range:-25 to 55;(4)maximum RF output power:2W/1W.Processing power is something that needs to be considered as the script is run as a low priority process within the software. An option that can be used to stop this controller mode, this stops GSM operation and provides all processing power for the script to be run.Code cannot be ported directly from an existing application and loaded directly onto the module. It must be re written in the SEM script language so that the module interpreter can function correctly. The Antenna Connector is a hub for transmission of the Radio Frequency (RF) signals from the module to the external customer-supplied antenna. GR47 is a MMCX connector that is mounted on the surface of the module. Most dealers should be able to supply this type of connector.
