1. INTRODUCTION
1.1 Description
The GTR64 is an intelligent GSM/GPRS control terminal that encapsulates everything you need for
m
wireless M2M capability in one compact unit. In conjunction with M2
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.

1.3 GTR-64 Wireless modems in a Communication System
Figure 1 and Figure 2 illustrate the main blocks of a wireless communication system using the wireless
modem. Figure 1 shows the communication system when a micro-controller is used. They also show the
communication principles of the system and the interface between the wireless modem and the
application and Figure 2 shows the communication system when the script is embedded on the wireless
modem. The definitions in the figures, as used elsewhere in this manual, are in accordance with the
recommendations of 3GPP TS 27.007.
The MS (mobile station) represents the wireless modem and SIM card. The wireless modem excluding
SIM card, is known as the ME (mobile equipment).
The DTE (data terminal equipment) is the controlling application. This can be either an external host or
an internal embedded application.
The DCE (data circuit terminating equipment) is the serial communication interface of the MS.

1.4 Main Features and Services
The GTR64 performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI and ITUT. The services and functions of the GTR64 are implemented by issuing customised applications
embedded on the device, or by AT commands issued internally, or over the RS232 serial interface.
1.4.1 Types of Mobile Station
The GTR64 is a
table below.
1.4.2 Short Message Service
The wireless modem supports the following SMS services:
• Sending; MO (mobile-originated) with both PDU (protocol data unit) and textvmode supported
• Receiving; MT (mobile-terminated) with both PDU and text mode supported
• CBM (cell broadcast message); a service in which a message is sent to all subscribers located in one or more
specific cells in the GSM network (for example, traffic reports)
• SMS status report according to 3GPP TS 23.40
The maximum length of a text mode SMS message is 160 characters using 7-bit encoding. The wireless
modem supports up to six concatenated messages to extend this function. Concatenation is performed by the
host application.
1.4.3 Voice Calls
The wireless modem offers the capability of MO (mobile originated) and MT (mobile terminated) voice calls,
as well as supporting emergency calls. Multi-party, call waiting and call divert features are available. Some of
these features are network operator specific.
For the inter-connection of audio, the wireless modem offers balanced analogue input and output lines. The
wireless modems support HR, FR, EFR and AMR vocoders.

1.4.4 Data
The wireless modem supports the following data protocols:
• GPRS (General Packet Radio Service)
The wireless modem is a Class B terminal. The wireless modem is GPRS multi-slot class10 (4+2)
enabled, capable of receiving at a maximum of four timeslots per frame (down link), and transmitting
in two timeslots per frame (up link). See section 1.4.5for multi-slot allocation by class.
• CSD (Circuit Switched Data)
The GR64 wireless modem is capable of establishing a CSD communication at 9.6 kbps over the air.

1.4.6 SIM Card
The GTR64 supports an external SIM card through the integrated SIM holder. Both 3V and 1.8V SIM
technology is supported. Older, 5V SIM technology is not supported.

The power consumption figures shown represent typical average current for maximum transmitted power,
single uplink (transmit) slot, and single downlink (receive) slot. The module will consume more average power
in different multi-slot configurations, the worst case being that of two uplink and three downlink slots.
1.5 Precautions
The GTR64 as a standalone item is designed for indoor use only. To use outdoors it must be integrated
into a weatherproof enclosure. Do not exceed the environmental and electrical limits as specified in
“Technical Data”, page 32.
