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 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 high-performance 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  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. When in regions where GPRS is not available, user 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 VERSION 1.03 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 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.

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. 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. 1.1.2 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. 1.1.3 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. 1.1.4 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 the property of FALCOM GmbH and may not be copied or circulated without permission. Page 10
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. 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! 1.1.6 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. 1.1.7 VEHICLE ELECTRONIC EQUIPMENT Check your vehicle manufacturer’s representative to determine if any on board electronic equipment is adequately shielded from RF energy. 1.1.8 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. 1.1.9 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. 1.1.10 CHILDREN 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.

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. 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. 1.1.13 NON-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.

The terms DTE (Data Terminal Equipment) and DCE (Data Communications Equipment) are typically used to describe serial ports on devices. Computers (PCs) generally use DTE connectors and communication devices such as modems and DSU/CSU devices generally use DCE connectors. As a general rule, DTE ports connect to DCE ports via straight through pinned cables. In other words, a DTE port never connects directly to another DTE port. Similarly, a DCE port never connects directly to another DCE port. The signalling definitions were written from the perspective of the DTE device; therefore, a Receive Data signal becomes an input to DTE but an output from DCE. TANGO55/i and TANGO56/i are designed for use as a DCE unit. Based on the aforementioned conventions for DCE-DTE connections it communicates with the customer application (DTE) using the following signals: TANGO55/i and TANGO56/i Terminal (DCE) to Application (DTE) TxD ◄----------------------- TXD RxD -----------------------► RXD RTS ◄----------------------- RTS CTS -----------------------► CTS DTR ◄----------------------- DTR DSR -----------------------► DSR DCD -----------------------► DCD RING -----------------------► RING Table 7: The signaling definitions between DTE and DCE.
TANGO55/I & TANGO56/I VERSION 1.03 3 GSM/GPRS APPLICATION INTERFACE 3.1 Description of operating modes The chapter below briefly summarizes the various operating modes referred to the following chapters. 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. Class B enables making or receiving a voice call, or sending/receiving a SMS during a GPRS connection. During voice calls or SMS, the GPRS services will be suspended and then resumed automatically after the call or SMS session has been ended. 3.1.1 Normal mode operation 3.1.1.1 GSM/GPRS SLEEP Various power save modes set with AT+CFUN command. Software is active to minimum extent. If the module was registered to the GSM network in IDLE mode, it is registered and paging with the BTS in SLEEP mode, too. Power saving can be chosen at different levels: The NON-CYCLIC SLEEP mode (AT+CFUN=0) disables the AT interface. The CYCLIC SLEEP modes AT+CFUN=5,6,7,8 and 9 alternatively activate and deactivate the AT interfaces to allow permanent access to all AT commands. 3.1.1.2 GSM IDLE Software is active. Once registered to the GSM network, paging with BTS is carried out. The module is ready to send and receive. 3.1.1.3 GSM TALK Connection between two subscribers is in progress. Power consumption depends on network coverage individual settings, such as DTX off/on, FR/EFR/HR, hopping sequences, antenna. 3.1.1.4 GPRS IDLE Module is ready for GPRS data transfer, but no data is currently sent or received. Power consumption depends on network settings and GPRS configuration (e.g. multislot settings). 3.1.1.5 GPRS DATA GPRS data transfer in progress. Power consumption depends on network settings (e.g. power control level), uplink/downlink data rates and GPRS configuration (e.g. used multislot settings).

TANGO55/I & TANGO56/I VERSION 1.03 3.1.2 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. Module will not be registered to GSM network. Limited number of AT commands is accessible.

TANGO55/I & TANGO56/I VERSION 1.03 Figure 6: SIM interface (interface E) 4.1.6 Interface F (Optical indicator interface) The actual state of the TANGO55/i and TANGO56/i is displayed by two LED’s on interface F of the unit (for more details see chapter 4.2 Functional description). Figure 7: Status indicator of modem 4.2 Functional description The GSM/GPRS modem TANGO55/i and TANGO56/i are mobile stations for the transmission of voice, data and fax calls as well as SMS in GSM/GPRS networks. The GSM/GPRS modems TANGO55/i and TANGO56/i consist of the following components: • GSM/GPRS transceiver • Power supply unit • Serial link (V.24) for data transmission and control • GPRS Class B, Class 2 or Class 10. If the GSM/GPRS modem is registered in the network, it acts just like a regular fax/data modem. To control the GSM modem there is an advanced set of AT-commands according to GSM ETSI 07.07 and 07.05 implemented. The two LED’s on the top of Interface C are showing the state of TANGO55/i and TANGO56/i. The yellow LED signals the actual connection of the modem (interface B or C) and the green LED signals power connection, GSM/GPRS network, a “RESET” function and “SOFT-ON ” procedure. This confidential document is the property of FALCOM GmbH and may not be copied or circulated without permission. Page 25
TANGO55/I & TANGO56/I VERSION 1.03 The actual state of modems is displayed by two LED’s at the connector on the top of interface C of the unit. Off Modem is off or run in SLEEP mode 600 ms On / 600 ms Off No SIM card inserted or no PIN entered, or network search in progress, or ongoing user authentication, or network login in progress. 75 ms On / 3 s Off Logged to network (monitoring control channels and user interactions). No call in progress. 75 ms On / 75 ms Off/ 75 ms On / 3 ms Off One or more GPRS contexts activated. Flashing Flashing Indicates GPRS data transfer: When a GPRS transfer is in progress, the LED goes on within 1 second after data packets were exchanged. Flash duration is approximately 0.5 s. Green LED (GSM) On On Depending on type of call: Voice call: Connected to remote party. Data call: Connected to remote party or exchange of parameters while setting up or disconnecting a call. Off Power off or interface C in use. Yellow LED On Power on, interface B in use or both interfaces (B & C) are not connected. 4.2.1 Ignition line The Ignition Line on Interface A uses an internal processor to control the timing of the “TURN-ON” procedure of the internal GSM modem. To switch the modem ON the Ignition Line has to be connected to a high voltage level of (10,8V ... 31,2V). The green LED on interface C shows the progress of the “TURN-ON” procedure (green indicator light). Enter PIN number of the inserted SIM card (if required). After a few seconds it will go flashing slowly (that means the registration into the network is successfully). To switch the modem off the commands AT+CPOF or AT+CFUN=0 (see AT commands manual) has to be issued. To switch the modem on again see above. 4.2.2 Serial handling The GSM/GPRS modem TANGO55/56 allows control of the GSM/GPRS modem over the interface B or Interface C. The interface B is a implementation of a serial interface corresponding to EIA-RS232-C. See table below for details: CCITT V24 Pin Description Direction 102 5 Signal Ground (GND) 103 3 Transmitted Data (TxD).

Page 26
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. See table for connections: Pin Description Direction 1 Power output 10V ± 5% 150mA OUT 2 Received Data (RxD) IN 3 Transmitted Data (TxD) OUT 4 Ground 5 SPK+ OUT 6 SPK- OUT 7 MIC+ IN 8 MIC- IN Table 13: Pin description fo RJ45 4.2.3 Reset configuration In case of malfunction the GSM/GPRS modem offers various RESET possibilities. For a RESET of the GSM/GPRS modem please use the following way: a) Operating voltage remains applied, the Ignition line of the modem remains connected to the operating voltage or any other external power source (10,8V ... 31,2V). b) Then, send for at least 100ms a LOW signal level to the Transmit Data [TxD] pin of the serial interface B or C (means: send a “BREAK” signal to the used Transmit Data [TxD] line from a terminal software). The “BREAK” signal forces the modem to perform a reset by driving the TxD pin of modem to the ground. c) Once the system detects an incomming signal through TxD pin (e.g. type AT <enter> on the terminal screen) the modem set itself into the command mode. (Via IGN line is also posible, by disconnecting the Ignition line (IGN) and connecting it again, the modem set itself also into the command mode). If the GSM software is still running, while the user feels the need to reset the modem, AT+CFUN=1,1 could be used. This will de-register the modem from the network and bring it into the state before the PIN has been entered. 4.2.4 Firmware update The download procedure is documented in chapter 8. 4.2.5 Turn off GSM/GPRS engine of the TANGO55/56 modems using AT command The best and safest approach to powering down the GSM/GPRS engine is to issue the AT^SMSO command. This procedure lets GSM engine log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as POWER DOWN mode. In this mode, only the RTC stays active. Before switching off the device sends the following response: ^SMSO: MS OFF OK This confidential document is the property of FALCOM GmbH and may not be copied or circulated without permission. Page 27
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. While the GSM engine is in POWER DOWN mode the application interface is switched off and must not be fed from any other source. 4.2.6 Maximum number of turn-on/turn-off cycles Each time the modems are shut down, data will be written from volatile memory to flash memory. The guaranteed maximum number of write cycles is limited to 100.000. 4.2.7 Automatic GPRS Multislot Class change Temperature control is also effective for operation in GPRS Multislot class 10. If the board temperature increases to the limit specified for restricted operation (see 2.3 for temperature limits known as restricted operating) while data are transmitted over GPRS, the module automatically reverts from GPRS Multislot TANGO55/56 /I56i returns to the higher Multislot class. If the temperature stays at the critical level or even continues to rise, TANGO55/56 will not switch back to the higher class. After a transition from Multislot class 10 to Multislot class 8 a possible switchback to Multislot class 10 is blocked for one minute. Please note that there is not one single cause of switching over to a lower GPRS Multislot class. Rather it is the result of an interaction of several factors, such as the board temperature that depends largely on the ambient temperature, the operating mode and the transmit power. Furthermore, take into account that there is a delay until the network proceeds to a lower or, accordingly, higher Multislot class. The delay time is network dependent. In extreme cases, if it takes too much time for the network and the temperature cannot drop due to this delay, the module may even switch off. For GPRS connection see related document [2].

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. If the power supply is using input-voltages of more than 50 Vrms or 75 V DC it is the response of the applicant to conform with the safety requirements of Telecommunication Terminal Equipment (such as 73/23/EEC). 7.1.1 External cable for power supply Power cable, included in the package, shall be used for power supply connection. The external power cable is a four-conductor cable with stripped and tinned ends. Connect the white and yellow leads of the external power cable to the positive side of the DC power source. Connect the brown lead of the external power cable to the negative side of the DC power source. The green lead of the external power cable should be left open (not connected). COUTION: Observe polarity when connecting the external power cable. Incorrect input polarity can damage the power adapter. The connector of power cable is a Micro-Fit 3.0 one.

TANGO55/I & TANGO56/I VERSION 1.03 7.2 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. The order numbers are:  ANT-001-M (with FME-male connector, for TANGO55/i)  ANT-010 (with FME-male connector, for TANGO56/i)  Dual-Band GSM antenna (with SMB-female connector, for TANGO55/i)  KA08-F (antenna cable with SMB-female and FME-female connectors) The TANGO55 modem with SMB connector incorporates a 'Snap On' latching action in order to make the connection easier with an excellent RF performance. An additional advantage is its small physical size. Figures (44.a and 44.b) below shows the possibilities of external GSM/GPRS antennas. If your TANGO55 modem provides an external SMB connector on the antenna interface both of the below designed GSM/GPRS antennas can be used. In case of using the ANT-001-M with FME connector, FALCOM GmbH provides a special adapter cable between the TANGO55 and FME antenna connector. The FALCOM type code of this adapter cable is KA08-F. Figure (44.a) shows an external GSM/GPRS antenna with FME connector (ANT-001-M). If your TANGO55 modem provides an external FME connector on the antenna interface only a GSM/GPRS antenna with FME connector (ANT-001-M) can be used. Figure 44.a: ANT-001-M with FME-male connector and KA08-F with SMB-female and FME-female connector. Figure 44.b: Dual-Band GSM antenna with SMB-female connector 7.3 Possible external headset A different microphone inputs and a different speaker outputs are supported by the TANGO55/56 modem, so an external headset interface through the RJ45 connector (interface C) is available. Follow the characteristics to install a headset: 2K differential Microphone impedance 2V Microphone bias voltage 0,5mA Microphone input current >32Ω (<1nF) Speaker impedance This confidential document is the property of FALCOM GmbH and may not be copied or circulated without permission.

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. In order to update a new TANGO55/56 firmware, please, follow step-by-step the instructions described below: • Point your web browser to www.falcom.de, go to support  drivers & firmware  TANGO55 or TANGO56 and download the “wswup_mc55_x.exe“ or wswup_mc56_x.exe Update program, respectively. • Connect the serial port of the TANGO55/56 to one of the available COM ports on your PC (e.g. COM1). • If TANGO55/56 is still powered on power it down. Make sure that the V+ and IGN lines are disconnected from the external power source. • Start “wswup_mc55_01.06.exe” Update program. The Dialog Window shown below appears. • Please, refer to the figure above for the following points. Select the Skip radio button near the Pre-Check progress bar. • Click on the “Serial Config” button, and in the “Com” settings box select the COM port where your TANGO55/56 is connected (i.e COM1) and in the “Baud” settings box select the Baud rate to 115200.
