1. INTRODUCTION 
1.1 Description 
The GTR64 is an intelligent GSM/GPRS control terminal that encapsulates everything you need for 
wireless M2M capability in one compact unit. In conjunction with M2
m
power package the GTR64 can 
host and control your wireless application, minimising the need for extra components. 
Alternatively, it can be used as a powerful standalone GPRS modem with its intrinsic TCP/IP stack. 
The GTR64 is a self contained terminal with its own SIM card reader and two standard connectors 
interfaces, minimising the need for further hardware development.. This terminal can be used as a 
powerful and flexible device that can be used in a wide range of telemetry and telematics applications 
that rely on the remote exchange of data, voice, SMS or faxes via the GSM cellular network. 
As well as providing a standard RS232 serial communication interface the GTR64 also has an audio 
interface allowing an analogue handset to be connected. Also a USB port is included to allows the 
connectivity to all relevant PCs and control boards in office and industrial environments. The expansion 
port has a wide and useful range of IOs that can be reconfigured to add functions and features that 
make your M2M solution both innovative and cost effective. 
The GTR64 can be used to provide a communications link for a variety of wireless applications including 
fleet and asset management, vending, security and alarm monitoring, e-maintenance and other 
telemetry applications. 
With quad band 900/1800 MHz and 850/1900 MHz, your applications can be used all over the world. 
The control terminal comes with a library of sample script applications to give developers a head start 
where needed. 
The GTR-64 incorporates a Wavecom (legacy Sony Ericsson) GR64/40 GSM/GPRS wireless CPU engine. 
The GTR64 terminal offers compatibility with both SonyEricsson legacy GM28/29 and GT47/48 terminals, 
with enhanced features.
