2. GT47/GT48 Control Terminals
2.1 Description
Two Control Terminals make up the family; GT47 and GT48, for use in
the E-GSM900/GSM1800 and GSM850/GSM1900 bands respectively.
The Control Terminal has a radio device embedded in it. The GT47
incorporates the GR47 radio device; the GT48 incorporates the GR48
radio device.
Note!
This manual refers to the GT47 and GT48 as Control Terminals. If there
is a difference in the functionality of the Control Terminals the GT47 and
GT48 information will be listed separately.
The Control Terminal is 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.
Small and lightweight, the Control Terminal has standard connectors and
an integral SIM card reader making it easy and quick to integrate. As well
as providing a standard RS232 serial communication interface the Control
Terminal also has an audio interface allowing an analogue handset to be
connected. When the Control Terminal is integrated into an external
application, a wireless communications system is created.
A typical end-to-end system consists of a micro controller in an external
application communicating, via the Control Terminal, with a remote
terminal or host using the GSM network. The micro controller uses a set of
AT commands to control the Control Terminal, and to set up the end-toend communications link, via its 9-way RS232 serial interface.
These Control Terminals are intended to be used by manufacturers, system
integrators, application developers and developers of a wide range of
equipment and business solutions, typically in the following fields:
• Security and alarms
• Vending
• Monitoring and control
• Utilities
• Fleet Management

2.3 Control Terminals in a Communication System
Figures 2.1 and 2.2 illustrate the main blocks of a wireless communication
system using the Control Terminal. Figure 2.1 shows the communication
system when the script is embedded on the Control Terminal and figure
2.2 shows the communication system when a micro-controller is used.
They also show the communication principles of the system and the
interface between the Control Terminal and the application. The
definitions in the figures, as used elsewhere in this manual, are in
accordance with the recommendations of GSM 07.07.
• The MS (mobile station) represents the Control Terminal and SIM card.
The Control Terminal 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.

2.4.7 Serial Communication
The Control Terminal enables an end-to-end communication path to be
established between the telemetry/telematics application, either hosted
internal or connected externally, and a remote terminal or host, via the
GSM network. Once a path has been set up, voice or data communication
can take place. An RS232 9-signal serial interface is available via the
Control Terminal’s 15-way high density data connector.
This primary serial interface can be used to:
1.C o ntro lthe G T47 via an external PC o r m ic ro -c o ntro ller using AT
c o m m ands;
2.Send and rec eive data.
The Control Terminal supports the full set of AT commands according to

Signal OUT-2 on the RJ12 connector is switched in parallel to signal
OUT-4 on the 15-pin high density socket. The individual output signals
are generated by two different low side switches inside the module driven
from a common control signal.
5.1.1 Power Supply Interface
The supply voltage VIN and GND are protected against polarity reversal
and over voltage.
The Control Terminal switches on automatically once the VIN voltage is
applied.
Note!
The Control Terminal will not switch on if TO_IN is shorted to ground
when the dc supply is applied.
Note!
For more information on switching the Control Terminal on and off please
see section “Operation”, page 39
Note!
Please be aware that the total current carried via either the VIN or GND
pins will be the sum of the intrinsic power consumption of the Control
Terminal and any drive current supplied via OUT-1 or OUT-2 (or other
IOs). The current on either of the VIN or GND pins must not exceed 1.5A.
Caution! It is recommended that the system integrator provides appropriate fusing
otherwise the Control Terminal may be damaged. See “Current
Consumption with external +4.8V Supply Active”, page 53 for more
details.

Extended I/O Signals
Digital Inputs
The digital input IN-1 is available on pin 3 of the RJ12 connector. Its state
is detected by IO5 of the embedded Radio Device engine, see Control
Terminal-Radio Device signal cross reference table, page 30.
The distinction between low level and high level signals is at the voltage
level of 3 V. Voltages above 3 V are detected as high level voltages and
voltages below 2.8 V are detected as low level.
Digital Outputs
The RJ12 power supply connector has two different output drivers:
• OUT-1 is driven by a high side switch that applies VIN to pin 5 of the
RJ12 connector. IO1 of the embedded radio device is used to activate
the OUT-1 signal, see Control Terminal - radio device signal cross
reference table, page 30.
• OUT-2 is driven by a low side switch that shorts pin 2 of the RJ12
connector to ground when activated. IO3 of the embedded Radio
Device engine is used to activate OUT-2, see Control Terminal - Radio
Device signal cross reference table, page 30.
IMAGE -TBD
VIN Monitoring
The voltage, VIN, can be monitored internally by the Control Terminal, for
example if the Control Terminal is supplied from an external battery.
ADC1 on the Radio Device is used for this purpose, see Control TerminalRadio Device signal cross reference table, and is calibrated to operate in the
voltage range 0 – 31.875 V. The resolution of the 8 bit converter, ADC1,
provides a measurement accuracy of approximately 3%.

5.2.1 Standard RS232 Serial interface and Signals
The module supports a standard RS232 serial interface (EIA/TIA 574) via
its 15 pin high density connector, shown above.
5.2.2 Serial Data
The Control Terminal supports the standard data character format of 1
start bit, 8 bit data, no parity plus 1 stop bit, in total 10 bits per character.
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).
5.2.3 Serial Data Signals - RD, TD
The default baud rate is 9.6kbps, however higher bit rates up to 230.4kbps
are supported and can be set by AT commands. At start-up the module
transmits and receives data at the default rate of 9.6kbps in either standard
AT mode or binary mode (the first received data - AT or binary format determines the operating mode).
Serial Data From GT47 (RD)
Pin 2
RD is an output signal that the Control Terminal uses to send data to the
external application.

LZ T123 7 605 P1C
5. ELECTRICAL DESCRIPTION
Serial Data To Control Terminal (TD)
Pin 3
TD is an input signal, used by the external application to send data to the
Control Terminal.
5.2.4 Control Signals - RTS, CTS, DTR, DSR, DCD, RI
Request to Send (RTS)
Pin 7
Used to condition the Control Terminal for data transmission. The default
level is inactive by internal pull down.
The exact behaviour of RTS is defined by an AT command. Software or
hardware flow control can be selected. Hardware flow control is the default
selection.
The application must pull RTS high to enable transmission from the
Control Terminal.
Clear To Send (CTS)
Pin 8
CTS indicates that the Control Terminal 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)
Pin 13
DTR indicates that the DTE is ready to send and receive data. It also acts
as a hardware ‘hang-up’, terminating calls when switched low. The signal
is active high. You can define the exact behaviour of DTR with an AT
command.
Data Set Ready (DSR)
Pin 6
An active DSR signal is sent from the Control Terminal to the application
(DTE) to confirm that a communications path has been established. DSR
has two modes of operation, use the AT command AT&S to set the mode.
Data Carrier Detect (DCD)
Pin 1
DCD indicates that the Control Terminal is receiving a valid carrier (data
signal) when high. You can define the exact behaviour of DCD with an AT
command.
Ring Indicator (RI)
Pin 10
RI indicates that a ringing signal is being received by the Control Terminal
when high. You can define the exact behaviour of RI with an AT
command.

LZ T123 7 605 P1C
5. ELECTRICAL DESCRIPTION
Alternative Configuration
It is possible to reconfigure one or more of the signals in this section (RTS,
CTS, DTR, DSR DCD and RI) to be used as digital inputs or outputs if the
full RS232 serial interface is not required. Configuration is achieved using
AT command (AT+E2IO) or via embedded application intrinsic functions,
please refer to Control Terminal-Radio Device signal cross reference table,
page 30.
To be reconfigured as a digital IO, each signal must retain the direction and
the logic voltage levels attributed to it when used as an RS232 signal. For
example DSR can only be reconfigured as a digital output with Vout ≥ ±5V.
5.2.5 Extended I/O Signals
Please refer to Control Terminal-Radio Device signal cross reference table,
page 30, for more information on the relationship between signal names
and pin numbers of the Control Terminal and the embedded Radio Device
engine.
Digital Inputs
Pin 4 & 11
Digital inputs IN-2 and IN-3 are available on the HD15 connector via pins
11 and 4 respectively. The inputs are detected via signals IO4 and IO7 of
the embedded Radio Device engine.
Note!
As an alternative configuration signals IN-2 and IN-3 can be used to
support a second RS232 serial interface as RTS-2 and TD-2. Further
information is given below.
Analog Input
Pin 15
The signal ANA_IN can be used for measuring analog input values in the
range 0 to 12.75V. ADC2 of the embedded GR47 is used to detect
ANA_IN.
The resolution of the converter is 8 bit with an measurement accuracy of
about 3%.
The input impedance of the ANA_IN pin is 50 kΩ.
Digital Outputs
Pin 5 & 12
Digital outputs OUT-3 and OUT-4 are available on the HD15 connector
via pins 5 and 12 respectively. The outputs are controlled via signals IO8
and IO3 of the embedded Radio Device engine.
Signal OUT-4 on the HD15 connector is switched in parallel to signal
OUT-2 on the RJ12 connector. The individual output signals are
generated by two different low side switches inside the terminal driven
from the common control signal, IO3. All Control Terminal output signals
28
LZ T123 7 605 P1C
5. ELECTRICAL DESCRIPTION
driven by low side switches return to open circuit when deactivated. This
allows the external application hardware to determine the desired logic
voltage levels with the appropriate pull-up.
The output drivers are low side switches which short the pin to GND if
they are activated.
Note!
As an alternative configuration signals OUT-3 and OUT-4 can be used to
support a second RS232 serial interface as RD-2 and CTS-2. Further
information is given below.
+4.8V Output Supply
Pin 9
There is a voltage regulator implemented inside the module that is capable
of supplying an external voltage source of +4.8V with a maximum current
of 75 mA.
The voltage source can be switched on/off with the DAC signal of the
internal Radio Device GSM engine.
By default the voltage source is switched on. A high level of 2.75V at the
DAC output of the Radio Device GSM engine will switch the voltage
source off.
Note!
The +4.8V source may be switched on/off via an embedded or external
application and so may be used as an optional digital output with levels of
+4.8V and open circuit.
5.2.6 Second RS232 Serial Interface
IN-3 and OUT-3 can be automatically reconfigured as signals TD-2 and
RD-2, of a second serial interface, by enabling UART3 of the internal
Radio Device. UART 3 may be enabled using AT command or intrinsic
function.
In addition, IN-2 and OUT-4 can be automatically reconfigured as signals
RTS-2 and CTS-2 of the second serial interface by enabling hardware flow
control for UART3 on the internal Radio Device. Hardware flow control
can be enabled using intrinsic function only.
Note!
The signal level thresholds for each of the digital inputs of the second serial
interface are: 3V0.2s, then release.
• activate the main RS232 control line DTR, low to high for >0.2s
The Control Terminal is fully operational after 4 seconds. Logging onto a
network may take longer than this and is outside the control of the Control
Terminal.
Note!
The Control Terminal will not switch on if TO_IN is shorted to ground
when the dc supply is applied.
8.2 Switching Off the Control Terminal
There are two ways to switch off the Control Terminal as described below.
• Use the appropriate AT command (AT+CFUN);
• pull signal TO_IN to ground for t >0.2s, then release.
8.3 Resetting the Control Terminal
A full system reset, independent of the status of the software, may be
applied to the Control Terminal as follows:
• assert HR_IN high for > 3.5s.
8.4 Operating States/LED
The Control Terminal has a green LED, as depicted below, which is used
to indicate various operating states. These states are described in following
table.

8.5 Power Save
The Control Terminal can power down the main RS232 IC when not
needed in order to minimise power consumption. The IC is powered up
automatically at start-up but can be powered down by setting the output
of IO2 on the embedded Radio Device (pin22) to low via AT command or
embedded application. Once powered down, the IC can be woken up by
setting the output of IO2 high on the Radio Device via AT Command.
Even when powered down the IC is able to pass a DTR signal received on
the serial interface. Therefore an embedded application that monitors
DTR, while the IC is powered down, can be made to wake up the IC, if a
signal is received, by setting IO2 on the Radio Device high.
8.6 Controller Mode
The Control Terminal, when powered up, will normally start up its GSM
signalling software and look to register on the GSM network. Any
embedded application script runs as a background process as and when the
GSM software is idle. A feature available via embedded applications allows
the Control Terminal to be placed in ‘controller mode’ whereby the Control
Terminal powers up with a minimal subset of radio functionality. The
GSM signalling software is halted and the embedded applications script
has full control of the processor.
Controller mode allows an application to run with more predictable
response times.

9. SAFETY AND PRODUCT CARE
9. Safety and Product Care
Please read the information in this section and the information in
“Installation of the Control Terminal”, page 44, before starting your
integration work.
9.1 Safety Instructions
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A
COPY OF THEM.
• Always ensure that use of the Control Terminal is permitted. The
Control Terminal may present a hazard if used in proximity to personal
medical electronic devices. As a rule, the Control Terminal must not be
used in hospitals, airports or planes.
• Never use the Control Terminal at a gas station, refuelling point,
blasting area or in any other environment where explosives may be
present.
• Operating the Control Terminal 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.
9.2 General Precautions
• The Control 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”, page 49.
• Avoid exposing the Control Terminal to lighted cigarettes, naked
flames or to extreme hot or cold temperature.
• Never try to dismantle the Control Terminal yourself. There are no
components inside the Control Terminal that can be serviced by the
user. If you attempt to dismantle the Control Terminal, you may
invalidate the warranty.
• The Control Terminal must not be installed or located where the
surface temperature of the plastic case may exceed 85° C.
• All cables connected to the Control Terminal must be secured or
clamped, immediately adjacent to the Control Terminal's connectors, to
41
LZ T123 7 605 P1C
9. SAFETY AND PRODUCT CARE
provide strain relief and to avoid transmitting excessive vibration to the
Control Terminal in the installation.
• Ensure the d.c. cable, supplying power to the Control Terminal, does
not exceed 3 metres. For longer distances please contact Sony Ericsson
Service and Support.
• 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 1.5A fuse in line with the positive supply. An appropiate
fuse should be used see section “Power Supply”, page 45
• Do not connect any incompatible component or product to the Control
Terminal.
Note!
Sony Ericsson may refuse warranty claims where evidence of product
misuse is found.
9.3 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 Control Terminal 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.
9.4 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 Control Terminal to a single antenna. The
Control Terminal can be damaged by radio frequency energy from the
transmitter of another Control Terminal.
• Like any mobile station, the antenna of the Control Terminal 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.
42
LZ T123 7 605 P1C
9. SAFETY AND PRODUCT CARE
• The Control Terminal 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.

10. INSTALLATION OF THE CONTROL TERMINAL
10. Installation of the Control Terminal
This chapter gives you advice and helpful hints on how to integrate the
Control Terminal into your application from a hardware perspective.
Please read the information given in “Safety and Product Care”, page 41
and then the read the information in this section before starting your
integration work.
10.1 Where to Install the Control Terminal
There are several conditions which need to be taken into consideration
when designing your application as they might affect the Control Terminal
and its function. They are:
10.1.1 Environmental Conditions
The Control Terminal 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.
10.1.2 Signal Strength
The Control Terminal 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 Control
Terminal is to a radio base station. You must ensure that the location at
which you intend to use the Control Terminal, 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 10.3.5, page 47.
When an application is completed, you can verify signal strength by
issuing the AT command AT+CSQ. See the GR47/GR48 AT Commands
Manual for more details.
Tip!
Before installing the Control Terminal, use an ordinary mobile telephone
to check a possible location for it. In determining the location for the
Control Terminal and antenna, you should consider signal strength as well
as cable length
44
LZ T123 7 605 P1C
10. INSTALLATION OF THE CONTROL TERMINAL
10.1.3 Connection of Components
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
Control Terminal or equipment.
10.1.4 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 described in section
“Short Message Service”, page 11.
10.2 How to Install the Control Terminal
10.2.1 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 1.5A fuse in line with the positive supply. This protects
the power cabling and Control Terminal.
10.2.2 Securing the Control Terminal
• Before securing the Control Terminal 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 Control Terminal prior to securing it in the application.
• Securely attach the Control Terminal to the host application using two
3mm diameter pan-head screws of appropriate length as shown below.
Caution! Do not exceed a torque of 25Ncm when tightening the fixings screws.
Excessive torque applied to the screws can crack the plastic case.
45
LZ T123 7 605 P1C
10. INSTALLATION OF THE CONTROL TERMINAL
10.3 Antenna
10.3.1 General
The antenna is the component in your system that maintains the radio link
between the network and the Control Terminal. 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.
10.3.2 Antenna Type
Make sure that you choose the right type of antenna for the Control
Terminal. Consider the following requirements:
• the antenna must be designed for the dual frequency bands in use:
EGSM 900/GSM 1800 for GT47, GSM 850/ GSM 1900 for GT48
• 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 Control
Terminal.
10.3.3 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 Control Terminal.
The Control Terminal’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.
46
LZ T123 7 605 P1C
10. INSTALLATION OF THE CONTROL TERMINAL
In general, CE-marked products for residential and commercial areas, and
light industry can withstand a minimum of 3V/m.
10.3.4 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.
10.3.5 Possible Communication 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.

Current Consumption of UART Transceiver in Standard Operation with
active/inactive serial Transmitter1
Note!
It is assumed that every driving signal of the UART1 transceiver
component inside the Control Terminal is driving an impedance of 3 KΩ
to its output level of max. 5.4V (see data sheet of RS232 device: e.g.
MAX3237).
The signals that are driven are: RXD, CTS, DSR, DTR, RI
