Analogue audio can be used for various configurations, including a car kit mode, portable hands free and
speakerphone (with an additional output gain stage).
Five audio profiles are available for GR64 users to configure various modes of operation. Each profile is
factory set to represent different modes, typical of general usage. The customer can modify profiles to
optimize acoustic performance to their specific application.
The analogue inputs and outputs share common uplink and downlink chains which are multiplexed, and
selectively switched by the user through AT-commands.
There five factory-set audio profiles as follows:
• Portable hands free
Low-level is recommended.
• Handset
Low-level is recommended.
• Car kit
Low-level is recommended.
• Speakerphone
High-level is recommended.
• Headset
Low-level or High-level can be used with headset, depending on requirements.
Portable hands free is the factory-set default profile. The modification, configuration, manipulation and
storage of audio profiles is achieved with the AT*E2EAMS (Audio Profile Modification) and AT*E2APR (Audio
Profile).

GTR64
3.6.1 Serial Data
The modem supports the standard data character format of
• 1 start bit, 7 or 8 data bits, 1 optional parity bit, 1 or 2 stop bits
• Programmable baud rate
• Auto-configuration mode with auto-baud and auto-format operation
In line with serial communication terminology the module is the data circuit-terminating equipment
(DCE) and the external application or computer is the data terminating equipment (DTE).
3.6.2 Serial Data Signals - RD, TD
The default baud rate of the UARTs is auto-baud. Baud rates of between 600 bauds to 460 kbauds are
possible. The wireless modem also supports 3GPP TS 27.010 multiplexing protocol, which starts when
the appropriate command is sent.
Serial Data From Modem (RD)
RD is an output signal that the modem uses to send data to the application.
Serial Data To Modem (TD)
TD is an input signal, used by the application to send data to the modem.
3.6.3 Control Signals - RTS, CTS, DTR, DSR, DCD, RI
Depending upon the user application, some, all, or none of the control signals may be needed. Each of
the control signals can alternatively be configured as a general purpose IO. When hardware flow control
is not used in communications between the application and the wireless modem, some applications may
require RTS and CTS to be connected to each other at the wireless modem. Users should familiarize
themselves with the specific implementation of their UART.
RTS and CTS are capable of transmitting at 1/10th of the data transmission speed for data rates up to
460kbps (byte-oriented flow control mechanism).
Request to Send (RTS)
Used to condition the DCE for data transmission. The default level is high by internal pull up.
The exact behaviour of RTS is defined by an AT command. Software or hardware control can be
selected. Hardware flow is the default control.
The application must pull RTS low to communicate with the modem.
The modem will respond by asserting CTS low, indicating it is ready for communication.
Clear To Send (CTS)
CTS indicates that the DCE is ready to transmit data. The default level is high. You can define the exact
behaviour of CTS through an AT command, and can select software or hardware flow control.
Data Terminal Ready (DTR)
DTR indicates that the DTE is ready to transmit and receive data. It also acts as a hardware ‘hang-up’,
terminating calls when switched high.The signal is active low. You can define the exact behaviour of
DTR with an AT command.
The DTR line can also be used to switch on the modem when activated for 0.2 seconds. The DTR line
must be deactivated prior to switching off the modem to ensure it switches off (powers down) correctly.
Data Set Ready (DSR)
An active DSR signal is sent from the modem to the application (DTE) to confirm that a communications
path has been established. DSR has two modes of operation, settable using the AT command AT&S.

GTR64
Data Carrier Detect (DCD)
DCD indicates that the DCE is receiving a valid carrier (data signal) when low. You can define the exact
behaviour of DCD with an AT command.
Ring Indicator (RI)
RI indicates that a ringing signal is being received by the DCE when low. You can define the exact
behaviour or RI with an AT command.
3.7 Expansion I/O port

3.7.2. I2C Serial Control Bus
Because of the nature of the I2C interface signals, SDA (data) & SCL (clock), they utilize a different type
of level-shifting technology to that of the ‘common’ IO. The I2C level shifter IC uses an open drain
construction with no direction pin, ideally suited to bi-directional low voltage I2C port translation to the
normal 3.3 V or 5.0 V I2C-bus signal levels. Unlike the common level shifters, the I2C level shifters have
a very low (6.5ohm RDSON) resistance between input and output pins.
The I2C level shifters use VREF as the host-side voltage reference and the internal 1.8V digital IO core
as the module-side reference.
The I2C interface comprises two signals; data (SDA) and clock (SCL). Both SDA and SCL have pull-up
resistors. Therefore, when the bus is free, both SDA and SCL are in a HIGH state.
The GTR64 implementation of I2C supports only a single master mode, with the module being the
master. The output stages of SDA and SCL must have an opendrain or open-collector to perform a
wired-AND function. The wired-AND function provides the I2C bus ability to perform clock
synchronization on the SCL line. Due to the wired-AND function, the SCL line will be held LOW by the
device with the longest LOW period. Therefore, the device with the shorter LOW period will be in a HIGH
wait-state during this time.

GTR64
Clock synchronization can be used as a handshaking mechanism, to enable receivers to cope with fast
data transfers. On a byte level, a slave (host application-side) I2C device may be able receive a data
transfer, but need time to store the byte received before it is ready to receive another byte. The
slave/receiver will therefore hold the SCL line low, after sending the acknowledge bit following the byte
received, thereby forcing the master into a wait state. Once the SCL is released by the slave/receiver,
the wait state of the master will end. This feature of the I2C standard is known as clock-stretching and
is supported by the GTR64.
The I2C interface supports Standard-mode (100kbps) and Fast-mode (400kbps). It also supports Normal
(7-bit) addressing and Extended (10-bit) addressing

SPI: The implementation of SPI uses the same command structure as the AT command AT*E2SPI. The
current implementation of this function only supports SPI Mode 0 (data is latched on a rising clock edge
and the default state of the clock is low).
4 wires are used - CLOCK (IO1 pin),
DATA INPUT (IO2 pin),

GTR64
All general purpose IO (GPIO) is programmable by the user. The I/O8 has alternate functionality already
associated with it; this is indicated in the default column. This I/O which has alternate function is
effectively multiplexed, so that the user chooses through AT commands the appropriate configuration for
their application.
GPIO is programmable for the following features:
• An input or output
• Level-sensitive or transition-sensitive
• Open drain or direct drive
• Polarity (inversion)
• Internal pull-up resistors
In the GTR64, all IO undergoes level shifting with VREF signal.
In the actual version of GTR64, VREF is connected internally to 3.6V internal VCC, so the level values
are referred to 3.6V.
Only by request, is it possible to change the VREF acting as an input, providing the reference input to
the host side level shifter devices. This enables users of varying technologies to connect directly to the
GR64’s IO by providing a reference from their own application IO.
Users should not that GPIO that is used truly bidirectional cannot be open drain type on both sides. At
least one side needs to be able to drive the signal both high and low.
3.7.5 Real Time Clock
The GTR64 contains a real time clock (RTC) to maintain accurate timekeeping and to enable
“timestamping” of messages.
The RTC is powered with the signal VRTC present in pin 7 of the expansion conector. The user must
connect this pin to an external energy device like a battery or super-capacitor to provide back-up power
to maintain the RTC. Example. If using a 300mF supercap the RTC can be maintain for at least 12 hours.
The GTR64 can accommodate this battery or super-cap inside, and the GTR64 can be ordered with this
special option by request. Please contact your sales nearest distributor.
3.8. Software Updates
It is possible and sometimes necessary to update the GTR64 software.
Updates must be carried out by a approved technician.
Please contact your supplier for details Service/Programming

4. OPERATION
4.1 Switching On the Modem
There are two ways to switch on the modem, once power is applied.
• either assert TO_IN high for > 0.2s;
• or activate the RS232 control line DTR, high for > 0.2s.
The modem is fully operational after 4 seconds. Logging onto a network may take longer than this and is
outside the control of the modem.
The modem can be configured to start up at the time power is applied by permanently tying power
connector signals TO_IN (pin 4) and VCC (pin 1) together. In this case DTR must be used to switch the
modem on again after it has been switched off or reset, while power is still applied.
Note! DTR must be cycled from low to high.
4.2 Switching Off the Modem
There are three ways to switch off (power down) the modem as described below:
• either use the AT+CFUN command;
• or assert HR_IN high for 1 - 2 seconds. A delay of up to 10s is experienced as the modem logs off the
network
• or assert TO_IN low to high for 1 - 2 seconds.
Note! The DTR line must be deactivated prior to switching off the modem to ensure the unit switches
off correctly.
4.3 Resetting the Modem
A full system reset, independent of the status of the software, may be applied to the modem as follows:
• assert HR_IN high for > 3.5s.
4.4 Operating States/LED
The modem has a green LED, as depicted below, which is used to indicate various operating states.
These states are described in following table.

5. EMBEDDED APPLICATIONS
The module has the capability to store and run customer written code in the form of a script during the
processors idle time, through the use of an on board interpreter.
5.1 Features
Main features of embedded applications are as follows.
•C based scripting language (Sony Ericsson specific)
•Over the air upgrade of scripts (NOT GSM software)
•Library of intrinsic functions
•Multiple on radio device script support
5.2 Implementation
The module has up to 512kbytes of space available for storage of two scripts in the scripting language
and 256kbytes of operating RAM. Structures included in this language are:
•If - then - else statements
•While loops
•For loops
All hardware interfaces that are normally available to the module through the AT commands are
available to the embedded application. Further drivers have been written such as M bus and I2C for use
by the embedded application (EA) through the use of the I/O pins.
5.2.1 Limitations
Since the module is processing the script using its own memory, limitations are placed onto the scripts
that are run.
A direct comparison cannot be made to a fully compiled C program in terms of size but a gauge of script
size is that if each line were 128 characters long in the script then the script could be 350 lines long.
Processing power is something that needs to be considered as the script is run as a low priority process
within the software. However, controller mode stops GSM operation and provides all the processing
power for the script to be run. See the Application Guide for more details.

Code cannot be ported directly from an existing application and loaded directly onto the radio device. It
must be re written in the Sony Ericsson Mobile script language so that the radio device interpreter can
function correctly.
5.2.2 M2mpower IDE (Integrated Developers Environment)
The IDE is a windows based package which allows the user to write, simulate, debug and download the
application into a radio device with the embedded application (EA) software. The standard version is
designed to run on Windows XP and 2000.
A guide is available for implementing applications using the developers kit and the embedded application
(EA) functionality.

6 SAFETY AND PRODUCT CARE
Please read the information in this section and the information in “Installation of the
Modem”, before starting your integration work!
6.1. Safety instructions
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM.
• Always ensure that use of the modem is permitted. The modem may present a hazard if used in
proximity to personal medical electronic devices. As a rule, the modem must not be used in hospitals,
airports or planes.
• Never use the modem at a gas station, refuelling point, blasting area or in any other environment
where explosives may be present.
• Operating the modem close to other electronic devices, such as antennas, television sets, and radios
may cause electromagnetic interference.
• This product is intended to be used with the antenna or other radiating element at least 20cm away
from any part of the human body. In applications where this rule cannot be applied, the application
designer is responsible for providing the SAR measurement test report and declaration.
• You are responsible for observing your country's safety standards, and where applicable, the relevant
wiring rules.
6.2. General precautions
The GTR64 Terminal as a stand alone item is designed for indoor use only. To use outside it must be
integrated into a weatherproof enclosure. Do not exceed the environmental and electrical limits as
specified in “Technical Data”.
• Avoid exposing the modem to lighted cigarettes, naked flames or to extreme hot or cold temperature.
• Never try to dismantle the modem yourself. There are no components inside the modem that can be
serviced by the user. If you attempt to dismantle the modem, you may invalidate the warranty.

GTR64
• The GTR64 Terminal must not be installed or located where the surface temperature of the plastic
case may exceed 85°C.
• All cables connected to the GTR64 Terminal must be secured or clamped, immediately adjacent to the
modem's connectors, to provide strain relief and to avoid transmitting excessive vibration to the modem
in the installation
• Ensure the d.c. cable, supplying power to the GTR64 Terminal, does not exceed 3 metres.
• To protect power supply cables and meet the fire safety requirements when the unit is powered from a
battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply.
• Do not connect any incompatible component or product to the GTR64 Terminal.
Note! GTR64 distribuitors and sales offices may refuse warranty claims where evidence of product
misuse is found.
6.3. SIM card precautions
Before handling the SIM card in your application, ensure that you are not charged with static electricity.
Use proper precautions to avoid electrostatic discharges.
• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder.
Caution! Do not touch these connectors! If you do, you may release an electrical discharge that could
damage the modem or the SIM card.
• When designing your application, the SIM card’s accessibility should be taken into account. We always
recommend that you have the SIM card protected by a PIN code.
This will ensure that the SIM card cannot be used by an unauthorized person.
6.4. Antenna precautions
If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided
by the antenna manufacturer.
• Never connect more than one modem to a single antenna. The modem can be damaged by radio
frequency energy from the transmitter of another modem.
• Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid EMI
(electromagnetic interference), you must determine whether the application itself, or equipment in the
application’s proximity, needs further protection against radio emission and the disturbances it might
cause. Protection is secured either by shielding the surrounding electronics or by moving the antenna
away from the electronics and the external signals cable.
• The modem and antenna may be damaged if either come into contact with ground potentials other
than the one in your application. Beware, ground potential are not always what they appear to be.
6.5. Radio Frequency (RF) exposure and SAR
Your wireless modem device is a low-power radio transmitter and receiver (transceiver). When it is turned on,
it emits low levels of radio frequency energy (also known as radio waves or radio frequency fields).
Governments around the world have adopted comprehensive international safety guidelines, developed by
scientific organizations, e.g. ICNIRP (International Commission on Non-Ionizing Radiation Protection) and
GTR64 Integrators Manual V.1.2

GTR64
IEEE (The Institute of Electrical and Electronics Engineers Inc.), through periodic and thorough evaluation of
scientific studies. These guidelines establish permitted levels of radio wave exposure for the general
population. The levels include a safety margin designed to assure the safety of all persons, regardless of age
and health, and to account for any variations in measurements.
Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed
by the body when using a transceiver. The SAR value is determined at the highest certified power level in
laboratory conditions, but the actual SAR level of the transceiver while operating can be well below this value.
This is because the transceiver is designed to use the minimum power required to reach the network.
The GR64 wireless modem device has been approved for applications where the antenna is located >20cm
from the body. In all other configurations the integrator is responsible for meeting the local SAR regulations.
Integrators of the GR64 wireless modem device are responsible for ensuring that they meet the SAR
regulatory requirements of the countries in which they intend to operate the device, and that their
documentation contains the relevant SAR declaration, certification information, and user guidance as
appropriate.
6.6. Personal Medical Devices
Wireless modem devices may affect the operation of cardiac pacemakers, hearing aids and certain other
implanted equipment. If a minimum distance of 15 cm (6 inches) is maintained between the GR64 module’s
radiating antenna and a pacemaker, the risk of interference is limited. If the integrator’s application is likely
to be situated in the vicinity of personnel, a suitable warning should be contained in the equipment manual to
this effect.
7. INSTALLATION OF THE MODEM
This chapter gives you advice and helpful hints on how to integrate the GTR64 Terminal into your
application from a hardware perspective.
7.1 Where to install the modem
There are several conditions which need to be taken into consideration when designing your application
as they might affect the modem and its function. They are:
7.1.1 Environmental conditions
The modem must be installed so that the environmental conditions stated in the Technical Data chapter,
such as temperature, humidity and vibration are satisfied.
Additionally, the electrical specifications in the Technical Data section must not be exceeded.
7.1.2 Signal strength
The modem has to be placed in a way that ensures sufficient signal strength. To improve signal
strength, the antenna can be moved to another position. Signal strength may depend on how close the
modem is to a radio base station. You must ensure that the location at which you intend to use the
modem, is within the network coverage area. Degradation in signal strength can be the result of a
disturbance from another source, for example an electronic device in the immediate vicinity. More
information about possible communication disturbances can be found in section 7.3.5.
When an application is completed, you can verify signal strength by issuing the AT command AT+CSQ.
See “AT+CSQ Signal Strength”.

GTR64
Tip! Before installing the modem, use an ordinary mobile telephone to check a possible location for it.
In determining the location for the modem and antenna, you should consider signal strength as well as
cable length.
7.1.3 Connections of components to GTR64 Terminal
The integrator is responsible for the final integrated system. Incorrectly designed or installed, external
components may cause radiation limits to be exceeded. For instance, improperly made connections or
improperly installed antennas can disturb the network and lead to malfunctions in the modem or
equipment.
7.1.4 Network and Subscription
Before your application is used, you must ensure that your chosen network provides the necessary
telecommunication services. Contact your service provider to obtain the necessary information.
• If you intend to use SMS in the application, ensure this is included in your (voice) subscription.
• Consider the choice of the supplementary services
7.2 How to install the modem
7.2.1 Power supply
• Use a high-quality power supply cable with low resistance. This ensures that the voltages at the
connector pins are within the allowed range, even during the maximum peak current.
• When the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line
with the positive supply. This protects the power cabling and modem.
7.2.2 Securing the modem
Before securing the modem take into account the amount of additional space required for the mating
connectors and cables that will be used in the application.
• Where access is restricted, it may be easier to connect all the cables to the modem prior to securing it
in the application.
• Securely attach the GTR64 Terminal modem to the host application using two 3mm diameter pan-head
screws
7.3 Antenna
7.3.1 General
The antenna is the component in your system that maintains the radio link between the network and the
modem. Since the antenna transmits and receives electromagnetic energy, its efficient function will
depend on:
• the type of antenna (for example, circular or directional);
• the placement of the antenna;
• communication disturbances in the vicinity in which the antenna operates.
In the sections below, issues concerning antenna type, antenna placement, antenna cable, and possible
communication disturbances are addressed. In any event, you should contact your local antenna
manufacturer for additional information concerning antenna type, cables, connectors, antenna
placement, and the surrounding area.
You should also determine whether the antenna needs to be grounded or not. Your local antenna
manufacturer might be able to design a special antenna suitable for your the application.

GTR64
7.3.2 Antenna type
Make sure that you choose the right type of antenna for the modem. Consider the following
requirements:
• the antenna must be designed for the one of the frequency bands in use; please ask your network
provider for more informations:
•
•
GSM 850/900 MHz
GSM 1800/1900 MHz;
• the impedance of the antenna and antenna cable must be 50Ω;
• the antenna output-power handling must be a minimum of 2W;
• the VSWR value should be less than 3:1 to avoid damage to the modem.
7.3.3 Antenna placement
The antenna should be placed away from electronic devices or other antennas. The recommended
minimum distance between adjacent antennas, operating in a similar radio frequency band, is at least
50cm. If signal strength is weak, it is useful to face a directional antenna at the closest radio base
station. This can increase the strength of the signal received by the modem. The modem’s peak output
power can reach 2W.
RF field strength varies with antenna type and distance. At 10cm from the antenna the field strength
may be up to 70V/m and at 1m it will have reduced to 7V/m. In general, CE-marked products for
residential and commercial areas, and light industry can withstand a minimum of 3V/m.
7.3.4 The antenna cable
Use 50Ω impedance low-loss cable and high-quality 50Ω impedance connectors (frequency range up to
2GHz) to avoid RF losses. Ensure that the antenna cable is as short as possible. The Voltage Standing-
Wave Ratio (VSWR) may depend on the effectiveness of the antenna, cable and connectors. In addition,
if you use an adapter between the antenna cable and the antenna connector, it is crucial that the
antenna cable is a high-quality, low-loss cable. Minimize the use of extension cables, connectors and
adapters. Each additional cable, connector or adapter causes a loss of signal power.
7.3.5 Possible communications disturbances
Possible communication disturbances include the following:
• Noise can be caused by electronic devices and radio transmitters.
• Path-loss occurs as the strength of the received signal steadily decreases in proportion to the
distance from the transmitter.
• Shadowing is a form of environmental attenuation of radio signals caused by hills, buildings, trees or
even vehicles. This can be a particular problem inside buildings, especially if the walls are thick and
reinforced.
• Multi-path fading is a sudden decrease or increase in the signal strength. This is the result of
interference caused when direct and reflected signals reach the antenna simultaneously. Surfaces such
as buildings, streets, vehicles, etc., can reflect signals.
• Hand-over occurs as you move from one cell to another in the GSM network. Your mobile application
call is transferred from one cell to the next. Hand-over can briefly interfere with communication and may
cause a delay, or at worst, a disruption.
