GM47R5/GM48R5 RADIO DEVICES
2 GM47r5/GM48r5 Radio Devices
2.1 About the GM47r5/GM48r5 Family
Two radio devices make up the family; GM47r5 and GM48r5,
for use in the E-GSM900/GSM1800 and GSM850/GSM1900
bands respectively.
Note! This manual refers to the GM47r5 and GM48r5 as radio
devices. If there is a difference in the functionality of the radio
devices the GM47r5 and GM48r5 information will be listed
separately.
The products belong to a new generation of Sony Ericsson
radio devices, and are intended to be used in machine-tomachine applications and man-to-machine applications. They
are used when there is a need to send and receive data (by
SMS, CSD, HSCSD, or GPRS), and make voice calls over the
GSM network.
The radio devices can either have applications embedded onto
them or they can be used as the engine in an application
created by the customer. The radio device can send and
receive data when a script is executed, the script can be run
internally from the radio device itself or from a micro-controller.
A typical application, involves a micro-controller and a radio
device, in which the micro-controller sends AT commands to the
radio device via an RS232 communications link.
2.2 Radio Devices in a Communication System
Figures 2.1 and 2.2 illustrate the main blocks of a wireless
communication system using the radio device. Figure 2.1
shows the communication system when the script is embedded
on the radio device 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 radio device 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 radio device and
SIM card. The radio device excluding SIM card, is known as
the ME (mobile equipment).

GM47R5/GM48R5 RADIO DEVICES
• 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.

5 System Connector Interface
5.1 Overview
Electrical connections to the radio device (except the antenna),
are made through the System Connector Interface. The system
connector is a 60pin, standard 0.05 in (1.27 mm) pitch device.
The system connector allows both board-to-board and board-tocable connections to be made. Use a board-board connector to
connect the radio device directly to a PCB, and a board-cable
connector to connect the radio device via a cable.
Figure 5.1 below shows the numbering of the connector pins.
A ground connection is provided at the mounting hole next to
the RF connector on the radio device as shown below. Connect
this ground point to the DGND pins of the radio device by the
shortest, low-impedance path possible. The purpose of this
connection is to allow any antenna ESD strikes to bypass the
radio device’s internal ground path.

Note! Unused pins can be left floating.
5.2.1 General Protection Requirements
• All 2.75 V digital inputs will continuously withstand and suffer
no damage in the power-on or power-off condition when
subjected to any voltage from - 0.5 V to 3.47 V (3.3 V + 5 %).
• All 2.75 V digital outputs will continuously withstand a short
circuit to any other voltage within the range 0 V to 3 V.
• All analogue outputs will continuously withstand a short
circuit to any voltage within the range 0 V to 3 V.
• The SIM output signals and the SIMVCC supply will
continuously withstand a short circuit to any voltage within
the range 0 V to 4.1V.
Note! Although the unit should be able to withstand the higher
voltages the unit should not be driven at the levels as it will
result in failures over time.
5.3 Grounds
Pin Signal Description
2, 4, 6, 8, 10, 12 DGND Digital ground
60 AGND Analogue ground
There are two ground connections in the radio device, AGND
(analogue ground) and DGND (digital ground). Pin assignments
are shown in the table above.
Note! AGND and DGND are connected at a single point inside the
radio device. They must not be joined together in your
application.
5.3.1 Analogue Ground - AGND
AGND is the return signal, or analogue audio reference, for
ATMS (Audio To Mobile Station) and AFMS (Audio From Mobile
Station). It is connected to the DGND inside the radio device
only. The application must not connect DGND and AGND.

5.7 Analogue Audio
Pin Signal Dir Description
57 AFMS O Audio from mobile station
59 ATMS I Audio to mobile station
60 AGND - Ground (return) for analogue audio
ATMS is the audio input, and AFMS is the audio output, of the
radio device. These signals can be used in car kit mode.
There are three factory-set audio profiles:
• portable handsfree
• handset
• car kit
Portable handsfree 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).
5.7.1 Audio To Mobile Station - ATMS
ATMS is the analogue audio input to the radio device.
Internally, the signal is sent to the CODEC (COder/DECoder),
where it is converted to digital audio in PCM (Pulse Code
Modulation) format. The encoded audio is sent to PCMOUT via
the internal PCM bus.
ATMS provides a DC bias when it is used as the microphone
input in Portable Handsfree applications. All other sources must
be a.c.coupled to avoid attenuation of low frequencies, and to
prevent incorrect biasing or damage to the ATMS input. Use a
capacitor greater than the value shown in the table below.
The ATMS input is a passive network followed by the transmit
part of the CODEC.

5.8.1 PCM Data Format
All of the radio device’s PCM signals, including signals between
its CODEC and DSP conform to the PCM data I/O format of the
industry standard DSP from Texas Instruments.
PCMCLK (bit clock) and PCMSYNC (frame synchronisation)
are both generated by the DSP within the radio device.
The DSP within the radio device is the master therefore all
external PCM clocks and data from external devices must be
synchronized to it
13-Bit PCM Mode
Bit Contents
D15 to D14 Equal to D13
D13 to D1 Two's complement of the 13-bit PCM
D0 LSB, not used
The radio device implements 13-bit PCM with the 13-bit data
embedded in a 16-bit word within a 24-bit frame (see Figure
5.8). Each PCM word contains 16-bits: D0 to D15. D13 to D1 is
the two’s complement value of the 13-bit PCM, with D13 as the
sign bit. D14 and D15 are always set to be equivalent with D13.
D0, the LSB, is not used as shown in Figure 5.7 below.

Note! Digital 2.75V CMOS input/output electrical characteristics apply.
The standard character format consists of 1 start bit, 8 bit data,
no parity and 1 stop bit. In all, there are 10 bits per character.
5.9.1 UART1 (RS232) - RD, TD, RTS, CTS, DTR, DSR, DCD and RI
UART1 signals conform to a 9-pin RS232 (V.24) serial port.
Note! UART1 signal levels do not match standard RS232 (V.28)
levels. The relationship between the levels is shown in the table
below.
RS232 level RD, TD RTS, CTS, DTR, DSR, DCD, CMOS level
< – 3 V 1 OFF > 1.93 V

Conversion between the radio device CMOS levels and RS232
levels can be achieved using a standard interface IC, such as
the Maxim Integrated Products MAX3237.
5.9.2 Serial Data Signals - RD, TD
The default baud rate is 9.6 kbits/s, however higher bit rates of
up to 460 kbits/s are supported, set by an AT command.
UART1 starts at a rate of 9.6 kbits/s in standard AT command
mode. The radio device also supports GSM 07.10 multiplexing
protocol and starts when the appropriate command is sent.

RTS and CTS are capable of transmitting at 1/10th of the data
transmission speed for data rates up to 460 kbit/s (byteoriented

if a 5 V SIM card is fitted.
SIM voltage levels, as shown in the following table, are
dependent on the type of SIM card detected by the radio
device.

5.10.1 SIM Detection - SIMPRESENCE
SIMPRESENCE is used to determine whether a SIM card has
been inserted into or removed from the SIM card holder. You
should normally wire it to the “card inserted switch” of the SIM
card holder, but different implementations are possible.

Signals which have an entry in the Default Signal column in the
above table are multiplexed.
The operational modes of multiplexed signals are controlled by
AT commands and also by intrinsic functions available to an
embedded application.
The following table gives you the input impedance. These
values only apply when the ports are configured as input
signals.
Parameter Min. Typ. Max. Units
Input impedance (pull-up) 50 100 120 kΩ
Note! I/O6 (LED) doesn’t have an internal pull up. If this pin is
configured as an input, it should not be left floating.
I/O7 (TD3) has a pull down instead of a pull up.
5.15 Extended I/O capabilities
To increase flexibility and variety of radio device peripherals,
the RS232 hardware flow control shares its physical interface
with the extended general purpose I/O capability. This sharing
means that it is not feasible to operate all these features
concurrently, however, with care, dynamic switching from one
feature to another is possible.
5.15.1 LED/IO6 Capabilities
The LED function pin can be used as a general purpose digital
I/O when the flashing LED function is not required. However,
this pin does not have an on-board pull-up resistor. It is required
that an external pull-up or pull-down resistor be provided by the
host circuitry when either not used or when used as a digital
input.
5.15.2 I#/O#
If pins labelled I# and O# are not being used for an alternative
function they may be used for general purpose inputs or outputs
respectively. The inputs have an on-board 100k pull-up resistor
and the outputs are driven rail-to-rail at 2.75V levels.
45
LZT 123 8020 R1A
SYSTEM CONNECTOR INTERFACE
5.15.3 UART3/IO#
The UART3 pins have been given alternative functions as
general purpose I/O, both pins may be used for either input or
output. However, the TX pin has a 100kΩ pull-down resistor to
ground and the RX pin has a 100kΩ pull-up resistor to 2.75V.
This must be taken into consideration when designing the host
circuit.
5.15.4 IO#/ADC#
To increase analog input capabilities, the radio device optimises
the I/O by multiplexing or sharing different features on single
pins. There are two digital I/O pins which now have an
additional ADC input. When configured as digital I/O, the
software will not read the voltages at the two new ADC inputs.
When configured as ADC inputs the software will configure the
digital I/O pins as input or high impedance tri-state. In this state
any applied voltage between 0V and 2.75V can be read as an 8
bit value.
Because the additional ADC inputs (ADC4 and ADC5) are
common with digital I/O, the input circuit of the ADC is not the
same as for the original circuits ADC1-3. It is important to
understand the input structure of the pin so that the correct
analog voltage is read by the application.

AT command is sent to the radio device. The radio device

Because the ADC inputs, ADC4 and ADC5, are common with
digital I/O, the input circuit of these ADCs is not the same as for
the circuits ADC1, ADC2 and ADC3. It is important to
understand the input structure of the pin so that the correct
analog voltage is read by the application (at position 'A' in
Figure 5.12 below). The input structure is provided in Figure
5.12. It consists of a 100kΩ pull-up to 2.75V followed by a
series 10kΩ and 1nF capacitor to ground which make a low
pass filter with a 3dB roll-off at about 16kHz. The input
impedance of the analog IC is 1MΩ minimum. At position 'A' in
Figure 5.12 below, the input characteristics are the same as for
the table above.

The Real Time Clock operates in two modes when connected
to a separate power supply:
• RTC normal mode: the radio device is in ON or OFF mode
and it is supplied with power (VCC is applied).
• RTC back-up mode: VCC is disconnected and the RTC is
maintained by a separate backup power supply connected
to the VRTC input (see Figure 5.13 below).
Backup power is provided by a capacitor, golden-capacitor or
battery in your application and must be connected to the VRTC
pin. During RTC normal operation, the back up source will be
charged.
In back-up mode, the back-up source must provide enough
power for RTC operation. Refer to the table for the amount of
current required.

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 radio device 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.

HINTS FOR INTEGRATING THE RADIO DEVICE
• In the final application, the antenna must be positioned more
than 20 cm away from human bodies. When this rule cannot
be applied, the application designer is responsible for
providing the SAR measurement test report and declaration.
• Even if SAR measurements are not required, it is considered
good practice to insert a warning in any manual produced,
indicating it is a radio product and that care should be taken.
7.2 Installation of the Radio Device
7.2.1 Where to Install the Radio Device
There are several conditions which need to be taken into
consideration when designing your application as they might
affect the radio device and its function. They are:
Environmental Conditions
The radio device 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.
Signal Strength
The radio device 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 radio device is to a radio base station.
You must ensure that the location at which you intend to use
the radio device, 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 page 58.
When an application is completed, you can verify signal
strength by issuing the AT command AT+CSQ. See the AT
Commands Manual for further details.
Note! Before installing the radio device, use an ordinary mobile
telephone to check a possible location for it. In determining the
location for the radio device and antenna, you should consider
signal strength as well as cable length
55
LZT 123 8020 R1A
HINTS FOR INTEGRATING THE RADIO DEVICE
Connection of Components to Radio Device
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 radio device or
equipment.
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 2.3.2 Short Message Service, page 10.
7.2.2 How to Install the Radio Device
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. An electrolytic capacitor should be placed close to
the power supply pins of the radio device to supply the peak
currents during burst transmission. See 5.4 VCC -
Regulated Power Supply Input.
• See section 5.2.1 General Protection Requirements, page
24.
Grounds
A ground connection is provided at the mounting hole next to
the RF connector on the radio device (see figure 5.1, page 20).
Connect this ground point to the DGND pins of the radio device
by the shortest, low-impedance path possible. The purpose of
this connection is to allow any ESD picked up by the antenna to
bypass the radio device’s internal ground path.
Note! It is recommended that you use a cable with a maximum
resistance of 5 m
56
LZT 123 8020 R1A
Ω for the ground connection.
HINTS FOR INTEGRATING THE RADIO DEVICE
Note! AGND and DGND are connected at a single point inside the
radio device. They must not be joined together in your
application.
Audio
Use a coupling capacitor in ATMS line if the application does
not use the radio device’s bias voltage. See also Figure 5.5
Microphone connections to the radio device, page 32.
Software Upgrade
To upgrade the software, the system connector must be
accessible in your application. The pins SERVICE, TD2, RD2
and the power signals are used for this purpose. Please contact
customer support for more details.
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 radio device. 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
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.
antenna operates.
7.3.2 Antenna Type
Make sure that you choose the right type of antenna for the
radio device. Consider the following requirements:
• the antenna must be designed for the dual frequency bands
in use:
57
LZT 123 8020 R1A
HINTS FOR INTEGRATING THE RADIO DEVICE
E-GSM900/GSM1800 for the GM47r5 and
GSM 850/GSM1900 for the GM48r5.
• 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 radio device.
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 radio device.
The radio device’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 highquality, 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 Communication Disturbances
Possible communication disturbances include the following:
• Noise can be caused by electronic devices and radio
transmitters.
58
LZT 123 8020 R1A
HINTS FOR INTEGRATING THE RADIO DEVICE
• 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.

LZT 123 8020 R1A
8 TCP/IP Stack
An on board IP/TCP/UDP stack has been integrated into the
software negating the need for the customer to implement one
in their own code base.
The TCP/IP stack is accessible via AT commands.
8.1 Implementation
The following types of commands allow various functions:
• Open/closing IP connection - Negotiates/closes a dynamic
IP address with the web server.
• Send/Receive TCP packets - Performs all TCP operations to
send and receive packets.
TCP/IP STACK
• Send/Receive UDP packets - Performs all UDP operations
to send and receive packets.
• Resolve URL to an IP address - Similar to nslookup
command in DOS
• Server/listen mode - This allows the unit to negotiate an IP
address for itself and then listen for incoming traffic.
The implementation effectively provides a transparent
communication link from the application to an internet server
over GPRS.

11 Introduction to the Universal Developer’s Kit
The developer’s kit is designed to get you started quickly. It
contains all the hardware you will need to begin the
development of an application. The only items you need to
provide are; a radio device, a computer, a SIM card with a
network subscription, and a knowledge of programming with AT
commands.
Note! Before connecting up and using the developer’s kit, we strongly
recommend you read “Integrating the Radio Device”, page 16
and all of this section. There are many switches, jumpers and
connector options in the developer’s kit. Knowledge of the
functionality of the radio device is therefore essential before you
start altering the hardware settings.
The main hardware of the UDK is an open board onto which
you plug the radio device. Connectors, switches, jumpers and
SIM card holder are provided to allow you to configure and
access all the functions of the radio device.

To Power on the unit, ensure a 12VDC supply is connected to
J101 and toggle the power switch S102. CR101 upper should
illuminate. Press S400 and hold down for at least 0.5 seconds.
CR103 upper should illuminate then about 4 seconds later
CR103 lower will illuminate and a random character should
appear in your terminal program (if connected to Serial port 1
and port settings are correct). Refer to GX-47/48 Family;
Connection, page 67.
USING THE UNIVERSAL DEVELOPER'S KIT
12.10 Flow Control
The developer's board has the ability to disable and enable the
routing of HW flow control signals between the PC and the
module. This is accomplished by setting S501 as per section
14.3.
Whenever communications difficulties arise with the module,
disable HW flow control both on the developer's board and in
your terminal program as a first step.
12.11 Power Down
When shutting down the developer's board and/or module it is
important that the module is allowed to perform and orderly
shutdown before power is removed. Do NOT simply pull the
plug. Press S400 (the hardware shutdown button) and hold
down for at least 1.5 seconds. Or send AT+CFUN=0. The radio
device takes a few seconds to shut down properly. CR103
upper will stay illuminated until shutdown is complete.
