Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel and incorporate these guidelines into all manuals supplied with the product. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Cinterion Wireless Modules GmbH assumes no liability for customer’s failure to comply with these precautions. When in hospitals or other health care facilities, observe the restrictions on the use of mobiles. Switch off the cellular terminal or mobile if to be instructed to do so by the guidelines posted in sensitive areas. Medical equipment may be sensitive to RF energy. The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be affected by interference from cellular terminals or mobiles placed close to the device. If in doubt about potential danger, contact the physician or the manufacturer of the device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep their hand-held mobile away from the pacemaker, while it is on. This personal subgroup always should check the distance to the mobile. Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it cannot be switched on inadvertently. The operation of wireless appliances in an aircraft is forbidden to prevent interference with communications systems. Failure to observe these instructions may lead to the suspension or denial of cellular services to the offender, legal action, or both. Check the local and actual laws about these themes. Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where blasting operations are in progress. Operation of any electrical equipment in potentially explosive atmospheres can constitute a safety hazard. Your cellular terminal or mobile receives and transmits radio frequency energy while switched on. Remember that interference can occur if it is used close to TV sets, radios, computers or inadequately shielded equipment. Follow any special regulations and always switch off the cellular terminal or mobile wherever forbidden, or when you suspect that it may cause interference or danger. Road safety comes first! Do not use a hand-held cellular terminal or mobile while driving a vehicle unless it is securely mounted in a holder for speakerphone operation. Before making a call with a hand-held terminal or mobile park the vehicle. Speakerphones must be installed by qualified personnel. Faulty installation or operation can constitute a safety hazard. Check the actual and local laws about these themes. BGS2T_HD_v01.301c Confidential / Released Page 14 of 47 2012-09-20 BGS2T Hardware Interface Description 1.3 Regulatory and Type Approval Information 1616 IMPORTANT! Cellular terminals or mobiles operate using radio signals and cellular networks. In that case connections cannot be guaranteed at all times under all conditions. Therefore, you should never rely solely upon any wireless device for essential communications, for example emergency calls. Remember, in order to make calls or receive calls the cellular terminal or mobile must be switched on in a service area with adequate cellular signal strength. Some networks do not allow for emergency calls if certain network services or phone features are in use (e.g. lock functions, fixed dialing etc.). You may need to deactivate those features before you can make an emergency call. Some networks require a valid SIM card to be properly inserted in the cellular terminal or mobile. If a power supply unit is used to supply the device it must meet the demands placed on SELV circuits in accordance with EN60950. The maximum permissible connection length between the device and the supply source should not exceed 3m. According to the guidelines for human exposure to radio frequency energy, an antenna connected to the FME jack of the device should be placed at least 20cm away from human bodies.

BGS2T_HD_v01.301c Confidential / Released Page 22 of 47 2012-09-20 BGS2T Hardware Interface Description 3.5 RS-232 Interface Variant 3232 3.5 RS-232 Interface Variant The RS-232 interface is implemented as a serial asynchronous transmitter and receiver conforming to ITU-T V.24 Interchange Circuits DCE. It is configured for 8 data bits, no parity and 1 stop bit, and can be operated at bit rates from 1200bps to 230kbps. Autobauding supports bit rates from 1.2kbps to 230kbps. For more information see also Section 3.5.1 and Section 3.5.2. 3.5.1 Power Supply The power supply of BGS2T RS232 has to be a single voltage source of VPLUS=8V…30V capable of providing a peak current (pulsed 2x577ms at T=4.615ms) of about 1.2A at 12V during an active transmission. The uplink burst causes strong ripple (drop) on the power lines. The drop voltage should not exceed 1V, but the absolute minimum voltage during drops must be >7.6V. The BGS2T is protected from supply voltage reversal. An external fast acting fuse >0.4A with melting integral I2t (0.15 … 0.25)A2s is necessary to use the BGS2T at a 12V or 24V unlimited power supply system. The power supply must be compliant with the EN60950 guidelines. A switching regulator regulates the input voltage for the internal supply. When power fails for >1ms, BGS2T resets or switches off. When power fails for >15s the RTC will be reset.

Ordering information can be found in Chapter 7. This 12V mains adapter comes with a 6-pole Western plug and provides an internal connection between IGT_IN pin and PLUS pin for auto ignition (power up). 3.5.1.1 Turn BGS2T on BGS2T is turned on by plugging an appropriate power supply unit between PLUS and GND of the 6-pole Western jack. While the RST_IN pin (pin4) is not active (voltage <2V) you can start the BGS2T by activating the RS-232 DTR line if in POWER DOWN mode. The IGT_IN signal (pin3) may be used to switch on BGS2T if in POWER DOWN mode. After startup of the BGS2T the RS-232 lines are in an undefined state for approx. 900ms. This may cause undefined characters to be transmitted over the RS-232 lines during this period. 3.5.1.2 Reset BGS2T An easy way to reset the BGS2T is entering the command AT+CFUN=x,1. For details on AT+CFUN please see [1]. As an alternative, you can shut down the BGS2T as described in Section 3.5.1.3 and then restart it as described in Section 3.5.1.1.

This procedure lets the BGS2T log off from the network and allows the software to enter a secure state and save data before disconnecting the power supply. After AT^SMSO has been entered the BGS2T returns the following result codes: ^SMSO: MS OFF OK ^SHUTDOWN The "^SHUTDOWN" result code indicates that the BGS2T turns off in less than 1 second. After the shutdown procedure is complete the BGS2T enters the POWER DOWN mode. The orange LED stops flashing (see Section 3.11 for a detailed LED description). The RTC is still fed from the voltage regulator in the power supply ASIC. Please note that if there is an auto ignition connection between PLUS and IGT_IN the module will restart automatically after a normal shutdown. Emergency restart: • In the event of software hang-ups etc. the BGS2T can be restarted by applying a voltage >8V to the RST_IN pin (pin 3) for more than 10ms. The RST_IN signal restarts the BGS2T. Caution: Use the RST_IN pin only when, due to serious problems, the software is not responding for more than 5 seconds. Pulling the RST_IN pin causes the loss of all information stored in the volatile memory since power is cut off immediately. Therefore, this procedure is intended only for use in case of emergency, e.g. if BGS2T fails to shut down properly. When the BGS2T enters the POWER DOWN mode, e.g. after you have issued the AT^SMSO command or activated the RST_IN signal, all RS-232 interface lines are active for a period of 50ms to max. 3.5s. This may cause undefined characters to be transmitted on the RS-232 lines which can be ignored. 3.5.1.4 Disconnecting power supply Before disconnecting the power supply from the PLUS pin, make sure that the BGS2T is in a safe condition. The best way is to wait 1s after the "^SHUTDOWN" result code has been indicated.

RS-485 is used in a lot of different fieldbus systems like Profibus, Interbus, Modbus and P-net. RS-485 uses a shielded twisted pair cable where the shield is used as ground return, and the inner pairs are used for balanced communication. The two conductors in each pair are called A and B. RS-485 is usually half-duplex. Data transmission speed depends on the length of the RS-485 bus cable and may be up to 115kbps. 3.6.1 6-Pin Header and Power Supply Via RS-485 interface, the host controller controls BGS2T RS485 including power supply and data transmission.

The best way is to wait 1s after the "^SHUTDOWN" result code has been indicated. 3.7 Automatic thermal shutdown An on-board NTC measures the temperature of the built-in BGS2 module. If over- or undertemperature is detected on the module the BGS2T automatically shuts down to avoid thermal damage to the system. Table 16 specifies the ambient temperature threshold for the BGS2T. The automatic shutdown procedure is equivalent to the power-down initiated with the AT^SMSO command, i.e. BGS2T logs off from the network and the software enters a secure state avoiding loss of data. In IDLE mode it takes typically one minute to deregister from the network and to switch off. Alert messages transmitted before the BGS2T switches off are implemented as Unsolicited Result codes (URCs). For details see the description of AT^SCTM command provided in [1]. Thermal shutdown will be deferred if a critical temperature limit is exceeded, while an emergency call or a call to a predefined phone number is in progress, or during a two minute guard period after power up. See [1] for details. 3.8 Hardware Watchdog The chipset of the internally used BGS2 module features a built-in hardware watchdog. The watchdog is activated automatically after the module powers on. In case the watchdog will not be reset within 2.5 seconds, the module will send a shutdown notification on the serial interface and will shut down itself. The module's firmware is designed in such a way that all the main tasks register to the reset procedure of the watchdog. If one of these tasks is not responding, the module will be shutdown. When using a power supply with the ignition line permanently active (as we use on our reference power supply) the BGS2T will be restarted automatically after such as shutdown. 3.9 RTC The internal Real Time Clock (RTC) of the BGS2T retains the time and date and handles the alarm (reminder) function. The AT+CCLK command serves to set the time and date, and AT+CALA specifies a reminder message. See [1] for details. A dedicated voltage regulator backs up the RTC even in POWER DOWN mode and enables BGS2T to keep track of time and date. However, please note that the Alarm mode described in [1], Section AT+CALA, is not intended for the BGS2T. The AT+CALA command can only be used to set a reminder message, but not to configure the mobile to wake up from POWER DOWN mode into Alarm mode. Therefore, after setting a timer with AT+CALA be sure not to shut down the BGS2T by AT^SMSO or RST_IN signal (BGS2T RS232 variant).

The card holder is a five wire interface according to GSM 11.11. A sixth pin has been added to detect whether or not a SIM card is inserted. SIM extracted SIM inserted Figure 8: SIM interface The SIM - with the circuit side facing towards the Cinterion logo - is inserted by gently pushing it into the SIM card holder until it snaps hold. It is now protected from accidental removal. The SIM can be removed from the card holder by using a flat object such as a screwdriver to carefully press the inserted SIM until it snaps out again. All signals of the SIM interface are protected from electrostatic discharge with spark gaps to GND and clamp diodes to 1.8V resp. 2.9V and GND. Removing and inserting the SIM card during operation requires the software to be reinitialized. Therefore, after reinserting the SIM card it is necessary to restart BGS2T. Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered after removing the SIM card during operation. Also, no guarantee can be given for properly initializing any SIM card that the user inserts after having removed a SIM card during operation. In this case, the application must restart the BGS2T.

Green LED (Power on/off) Orange LED (Operating status) Figure 9: Status LED The orange LED is driven by a line of the integrated BGS2 module which can be configured by using the AT^SSYNC command. For the purpose of the BGS2T it is recommended to retain the default setting of AT^SSYNC=1 (AT^SSYNC=0 is not applicable). The following table lists the possible LED patterns and describes the operating status of the BGS2T indicated by each pattern if AT^SSYNC=1. During the transition from one LED pattern to another the "on" and/or "off" periods of the LED may vary in length. This is because an event that triggers the change may occur any time and, thus, truncate the current LED pattern at any point.

Figure 10: Antenna connector The system impedance is 50. In any case, for good RF performance, the return loss of the customer application’s antenna should be better than 10dB (VSWR < 2). BGS2T withstands a total mismatch at this connector when transmitting with power control level for maximum RF power. Inside the BGS2 module an inductor to ground provides additional ESD protection to the antenna connector. To protect the inductor from damage no DC voltage must be applied to the antenna circuit. For the application it is recommended to use an antenna with an SMA (male) connector: Please note that the terminal should be installed and operated with a minimum distance of 20cm between the antenna connected to the terminal and any human bodies. Also, the transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The allowed maximum antenna gain for stand-alone situation is 7.24dBi (<1GHz) and 3.30dBi for the high bands (>1.7GHz).

Within the extended temperature range (outside the normal operating temperature range) the specified electrical characteristics may be in- or decreased. Due to temperature measurement uncertainty, a tolerance of ±3°C on these switching thresholds may occur. If the BGS2 module temperature rises close to the limit specified for normal operation, while data is transmitted over GPRS, the module automatically reverts from GPRS Multislot Class 10 (2Tx slots) to GPRS Multislot Class 8 (1Tx). This reduces the power consumption and, consequently, causes the board’s temperature to decrease. Once the temperature drops by 5 degrees, the module returns to the higher Multislot Class.
