TANGO55/I & TANGO56/I VERSION 1.03 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 & TANGO56/I VERSION 1.03 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.

TANGO55/I & TANGO56/I VERSION 1.03 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. 1.1.1 GENERAL Your modem utilises the GSM standard for cellular technology.
TANGO55/I & TANGO56/I VERSION 1.03 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. 1.1.5 DRIVING Check the laws and regulations on the use of cellular devices in the area where you drive. Always obey them.
TANGO55/I & TANGO56/I VERSION 1.03 1.1.11 BLASTING 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. 1.1.12 POTENTIALLY 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.

Definition of the GPRS class B mode of operation: The definition of GPRS class B mode is, that the MS can be attached to both GPRS and other GSM services, but the MS can only operate one set of services at a time.
TANGO55/I & TANGO56/I 3.1.2 VERSION 1.03 Power down Normal shutdown after sending the AT^SMSO command. The Power Supply ASIC (PSU-ASIC) disconnects the supply voltage from the base band part of the circuit. Only a voltage regulator in the PSU-ASIC is active for powering the RTC. Software is not active. The serial interfaces are not accessible. Operating voltage remains applied. 3.1.3 Alarm mode Alarm mode restricted operation launched by RTC alert function while the module is in POWER DOWN mode.

No call in progress.
TANGO55/I & TANGO56/I VERSION 1.03 Both interface B and C are not independent usable. The interface B has the highest priority. If you don’t want to use the interface B you must deactivate the signals RTS (or remove connection). With the interface C you have the audio and control functionality on one interface.
TANGO55/I & TANGO56/I VERSION 1.03 ^SHUTDOWN After sending AT^SMSO do not enter any other AT commands. There are two ways to verify when the modems turn off: Wait for the URC “SHUTDOWN”. It indicates that data have been stored non-volatile and the modems turn off in less than 1 second. Be sure not to disconnect the operating voltage VVin+ before the URC “SHUTDOWN” has been issued. Otherwise you run the risk of losing data.

TANGO55/I & TANGO56/I VERSION 1.03 7 APPENDIX 7.1 Recommendations for power supply It is recommended to use the PS002 power supply. Also any other power supply in the range of 10.8 ... 31,2 V DC can be used. It should be able to deliver 2A peak current (for 577µs, rise time 10µs, period 4.615ms, caused by GSM-typical radio transmission), where the ripple voltage of the power supply is recommended to be lower than 300mV.
TANGO55/I & TANGO56/I 7.2 VERSION 1.03 Possible external antenna There is no antenna included in the deliver package, but the below designed antennas can be used. The designed antenna in the figure below are provided by Falcom GmbH.
TANGO55/I & TANGO56/I VERSION 1.03 8 HOW TO UPDATE THE NEW FIRMWARE INTO THE TANGO55/56 MODEMS In order to allow users of TANGO55/56 to utilize newly released firmware, a program has to be available to update the on-board Flash-Memory. The update program with the new firmware will be distributed electronically via Internet or CD. The update procedure of a new firmware erases the whole internal flash memory and the presettings stored on it will be absolutely erased, too.
TANGO55/I & TANGO56/I VERSION 1.03 • Close this dialog box by clicking on the OK button. • Now, (imoprtant !!!!) to start the firmware update, firstly connect the IGN line to the external power source (set to HIGH from 10.8 to 32 VDC), then press the “START” button and within 1 second after the “START” button has been clicked, connect the V+ line to the external power source (set to HIGH from 10.8 to 32 VDC). • The current positions of the programming progress will be displayed in the progress bars.
TANGO55/I & TANGO56/I VERSION 1.03 If download has been completed successfully, power down the TANGO55/56 (disconnect the V+ line). The TANGO55/56 with the new firmware is automatically started at the next power up (connect the V+ and the IGN line to the external power source).
