0 INTRODUCTION
TANGO55/i and TANGO56/i are designed for use on any GSM network in the world.
TANGO55/i and TANGO56/i are Tri-Band GSM/GPRS engines that work on three
frequencies GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz or 850 MHz, DCS 1800
MHz, PCS 1900 MHz, respectively. These full type approved integrated modems
constitute a self contained, fully integrated implementation of the GSM/GPRS.
TANGO55/i and TANGO56/i feature GPRS class B, class 10 (making download at
speeds up to 85 kbps) and support the GPRS coding schemes CS-1, CS-2, CS-3 and
CS-4.
TANGO55/i and TANGO56/i modems incorporate all you need to create highperformance GSM/GPRS solutions; base band processor, power supply ASIC,
complete radio frequency circuit including a power amplifier, internal and external
SIM interfaces and an antenna interface as well.
The physical interface to the cellular application is made through a RS-232
connector. It consists of 9-pin RS232 interface, required for controlling the unit and
transferring data. They can be directly connected via RS232 interfaces to the serial
port of a desktop or notebook computer. Interfaces for audio signals and applying
power supply are also available.
The external dual band or triple band antenna can directly be connected to the
integrated 50 Ω connector on the modem.
The TANGO55/56 are mobile stations for transmission of voice, data calls and FAX as
well as short messages (SMS - Short Message Service) in GSM Network.
To control the GSM module there is an advanced set of AT commands according to
GSM ETSI (European Telecommunications Standards Institute) 07.07 and 07.05
implemented.
About GPRS:
GPRS is standard for General Packet Radio Service that is an add-on to the GSM
(Global System for Mobile Communications) cellular network - a type of network
used to provide cellular phone service.
In regions where GPRS is not available, users can still access their important
information with GSM 14.4 kbps data connections.
Users are advised to quickly proceed to the “Security” chapter and read the hints
carefully.
0.1 The differences between TANGO55/i & TANGO56/i
modems
TANGO55 is a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asian Networks.
TANGO55i is also a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asia Networks. The TANGO55i modem provides a
specific software and hardware (internal TCP/IP stack software with
hardware extension) which has been internally implemented for using
the embedded TCP/IP stack software.

TANGO55/i & TANGO56/i User's Manual Version 1.05
The integration of TCP/IP stack with hardware extension (a TCP/IPmodule added) into the equipment converts it to a stand-alone client
that can be connected to the internet via GPRS network. The modem
can also send and receive data by GSM (set into Command-Mode)
and GPRS network using TCP/IP stack. It supports SMS, DATA and FAX
calls. The TANGO55i modem can be easily controlled by using TCP and
AT commands. The “TCP Command Set” manual is also issued as
separate document and is available on the distributed CD for the
TANGO55i’s users.
TANGO56 is a Tri-band GSM/GPRS device that operates on three frequencies
GSM 900 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the European and Asia Networks.
TANGO56i is also a Tri-band GSM/GPRS device that operates on three frequencies
GSM 850 MHz, DCS 1800 MHz and PCS 1900 MHz, and is available to use
in the American Networks. However, the TANGO56i modem contains
1800 MHz GSM functions that is not operational (not allowed for use) in
U.S. Territories. This filing is only applicable for 850MHz GSM/1900 MHz
PCS operations, whereby only these frequencies (850MHz GSM/1900
MHz PCS) are possible to be used in U.S. Territories. The TANGO56i
modem provides a specific soft- and hardware (internal TCP/IP stack
software with hardware extension) which has been internally
implemented for using the embedded TCP/IP stack software.
The integration of TCP/IP stack with hardware extension (a
TCP/IP-module added) into the equipment converts it to a stand-alone
client that can be connected to the internet through any GSM
850/1800/1900 network. The modem can also send and receive data
by GSM (set into the Command-Mode) and GPRS network using TCP/IP
stack. It supports SMS, DATA and FAX calls. The TANGO56i modem can
be easily controlled by using TCP and AT commands. The “TCP
Command Set” manual is also issued as separate document and is
available on the distributed CD for the TANGO56i’s users.
Regarding the electrical interfaces, mechanical specification (dimension, form etc.)
and electrical specification are the same to all modems.
Please note that, according to your requirement you can choose the desired
device.

1 SECURITY
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM/GPRS MODEM
READ THIS INFORMATION BEFORE USE !
Your GSM/GPRS modem is one of the most exciting and innovative electronic
products ever developed. With it you can stay in contact with your office, your
home, emergency services, and others, wherever service is provided.
1.1 General
Your modem utilities the GSM standard for cellular technology. GSM is a newer radio
frequency (« RF ») technology than the current FM technology that has been used
for radio communications for decades. The GSM standard has been established for
use in the European community and elsewhere.
Your modem is actually a low power radio transmitter and receiver. It sends out and
receives radio frequency energy. When you use Your modem, the cellular system
handling your calls controls both the radio frequency and the power level of your
cellular modem.
1.2 Exposure to RF energy
There has been some public concern about possible health effects of using GSM or
GSM/GPRS modem. Although research on health effects from RF energy has
focused for many years on the current RF technology, scientists have begun
research regarding newer radio technologies, such as GSM. After existing research
had been reviewed, and after compliance to all applicable safety standards had
been tested, it has been concluded that the product is fit for use.
If you are concerned about exposure to RF energy there are things you can do to
minimise exposure. Obviously, limiting the duration of your calls will reduce your
exposure to RF energy. In addition, you can reduce RF exposure by operating your
cellular modem efficiently by following the below guidelines.
1.3 Efficient modem operation
For Your modem to operate at the lowest power level, consistent with satisfactory
call quality:
If Your modem has an extendible antenna, extend it fully. Some models allow you to
place a call with the antenna retracted. However Your modem operates more
efficiently with the antenna fully extended.
Do not hold the antenna when the modem is « IN USE ». Holding the antenna affects
call quality and may cause the modem to operate at a higher power level than
needed.
1.4 Antenna care and replacement
Do not use the modem with a damaged antenna. If a damaged antenna comes
into contact with the skin, a minor burn may result. Replace a damaged antenna
immediately. Consult your manual to see if you may change the antenna yourself. If
so, use only a manufacturer-approved antenna. Otherwise, have your antenna
repaired by a qualified technician.
This confidential document is a property of FALCOM and may not be copied or circulated without previous permission.
Page 11 of 46
TANGO55/i & TANGO56/i User's Manual Version 1.05
Use only the supplied or approved antenna. Unauthorised antennas, modifications
or attachments could damage the modem and may contravene local RF emission
regulations or invalidate type approval.
1.5 Driving
Check the laws and regulations on the use of cellular devices in the area where you
drive. Always obey them. Also, when using Your modem while driving, please: give
full attention to driving, pull off the road and park before making or answering a call
if driving conditions so require. When applications are prepared for mobile use they
should fulfil road-safety instructions of the current law!
1.6 Electronic devices
Most electronic equipment, for example in hospitals and motor vehicles is shielded
from RF energy. However RF energy may affect some malfunctioning or improperly
shielded electronic equipment.
1.7 Vehicle electronic equipment
Check your vehicle manufacturer’s representative to determine if any on board
electronic equipment is adequately shielded from RF energy.
1.8 Medical electronic equipment
Consult the manufacturer of any personal medical devices (such as pacemakers,
hearing aids, etc...) to determine if they are adequately shielded from external RF
energy.
Turn Your modem OFF in health care facilities when any regulations posted in the
area instruct you to do so. Hospitals or health care facilities may be using RF
monitoring equipment.
1.9 Aircraft
Turn Your modem OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use in the air.
To prevent possible interference with aircraft systems, Federal Aviation Administration
(FAA) regulations require you to have permission from a crew member to use Your
modem while the plane is on the ground. To prevent interference with cellular
systems, local RF regulations prohibit using Your modem whilst airborne.
1.10Children
Do not allow children to play with Your modem. It is not a toy. Children could hurt
themselves or others (by poking themselves or others in the eye with the antenna, for
example). Children could damage the modem, or make calls that increase Your
modem bills.

1.11Blasting areas
To avoid interfering with blasting operations, turn your unit OFF when in a « blasting
area » or in areas posted : « turn off two-way radio ». Construction crew often use
remote control RF devices to set off explosives.
1.12Potentially explosive atmospheres
Turn Your modem OFF when in any area with a potentially explosive atmosphere. It is
rare, but Your modem or its accessories could generate sparks. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fuelling areas such as petrol stations ; below decks on boats ;
fuel or chemical transfer or storage facilities ; and areas where the air contains
chemicals or particles, such as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives, in the compartment of
your vehicle which contains Your modem or accessories. Before using Your modem
in a vehicle powered by liquefied petroleum gas (such as propane or butane)
ensure that the vehicle complies with the relevant fire and safety regulations of the
country in which the vehicle is to be used.
1.13Non-Ionising radiation
As with other mobile radio transmitting equipment, users are advised that for
satisfactory operation and for the safety of personnel, it is recommended that no
part of the human body be allowed to come too close to the antenna during
operation of the equipment.
The radio equipment shall be connected to the antenna via a non-radiating 50Ohm
coaxial cable.
The antenna shall be mounted in such a position that no part of the human body will
normally rest close to any part of the antenna. It is also recommended to use the
equipment not close to medical devices as for example hearing aids and
pacemakers.
