9 i-modul HSPA basic 1.0 Technical Data 2.3 Power supply The i-modul HSPA basic 1.0 can consume up to 3 A temporarily during sending (transmit burst) for a time slot (577 µs each ms). If the power supply cannot deliver this current, no login is possible or the connection establishment is terminated with NO DIALTONE or NO CARRIER.

C U ( I max L I U q )* t ESR U mod 9

10 Technical Data i-modul HSPA basic 1.0 The following applies: t: Duration of a transmit burst t = 577µs I q : The voltage controller can supply a current I q of 1 A at 5 V in this example. I L : The GSM engine can be considered as a current sink with an I L of 2.5 A in the moment of the transmit burst. This is the maximum possible value, which may occur. The actual value depends on the quality of the GSM signal at the site and the adaptation of the antenna. ΔU max : maximum allowed voltage drop (from the nominal voltage) at the GSM engine (during the transmit burst). Specification: ΔU max = 400 mv U mod : Voltage drop at the connector transitions of the i-modul HSPA basic 1.0. Typically: U mod = 100 mv U ESR : Voltage drop at R ESR (equivalent series resistor) of the used electrolytic capacitors. Assumption: U ESR 100 mv This results in the specified case for the capacitor C: (2,5A 1A) *577 s C 400mV 100mV 100mV 4327,5 F This result is the lower limit for the capacity. Moreover, aging (by thermal load) as well as the high tolerance of electrolytic capacitors (typically 20%) must be observed. In order to keep the influence of the ESR (equivalent series resistance) of the capacitor as low as possible, the capacity should be divided into several capacitors connected in parallel (preferably low ESR types). In order to provide sufficient reserve, a parallel connection of 2 pcs µf and one 1000 μf electrolytic capacitors with 10 V dielectric strength is recommended for example. The compliance of the ESR must be tested again after selecting the components. RESR U ESR 100mV U ESR RESR 66, 67m I I I I 2,5A 1A L q L q The complete ESR of the used capacitors should not exceed a value of mω to comply with the assumption of U ESR = 100 mv made in the capacity calculation. 10

11 i-modul HSPA basic 1.0 Technical Data Example: Electrolytic capacitors from the LXZ series of "NIPPON CHEMI-CON" are used: LXZ 10 VB 1000 J16 for 1000µF with an RESR of typ. 68 mω LXZ 10 VB 2200 K20 for 2200µF with an RESR of typ. 38 mω R ESRtot = 68 mω 38 mω 38 mω = mω Moreover, it must be observed when designing the power supply, that the back-up capacitors are placed as close as possible to the connector transitions of the module, and the VCC tracks are as wide as possible to reduce the line resistance here. 2.4 SIM card The i-modul HSPA basic 1.0 requires a 3 or 1.8 Volt SIM card from a GSM provider for operation. The SIM card is the identification against the network provider. The SIM card must be inserted into the holder with the contacts facing down that the contacts get contact. Caution! Damage of the SIM card! Function loss of the SIM card. Changing the SIM card must only be performed with deenergized device. Moreover, it is possible to route the pins outside to implement an external SIM card holder. Otherwise, the pins remain unconnected. Certain approval guidelines are valid for implementing an external SIM card holder, e.g. the maximum line length and the used SIM card holder are defined. Refer to support@insys-tec.de for more detailed information. 11

The outputs are also within the TTL specification; however, it must be observed to control the inputs with CMOS levels. Generally, an application circuitry with components of the HCT family is recommended, which complies with a control with CMOS levels and a voltage tap according to TTL. 25 SYNC Output Optional output for connecting a TTL logic or a low-power LED. A serial resistor (680 Ohm) is required. Enabled: Disabled: 3 V GND Signalling: Indication of the GSM/GPRS transmit burst. The SYNC pin will be enabled 180 µs before a transmit burst and remains enabled during the transmit burst. On the one hand, this can indicate any send activity of the GSM/GPRS engine generally via an LED. On the other hand, this can be used to determine the time of increased power consumption to be able to supply the i-modul HSPA basic 1.0 with sufficient power.

17 i-modul HSPA basic 1.0 Connections 3.8 Connection Example for the SIMPRES Input SIMPRES informs the GSM engine whether a SIM card is inserted (low signal) or not (high signal). If the GSM engine detects that a SIM card is inserted, it enables the supply voltage for the SIM card. For the case that the SIMPRES input is not to be used in the application, a pulldown resistor pretends the presence of a SIM card to the GSM engine that this enables a continuous SIM supply. If SIMPRES is to be used, this pull-down resistor must be "overwritten". For this, use the circuitry in Figure 6. If the switch S1 is open, T1 connects through and VCC_+5V is present at the SIM- PRES input via R3. R3 forms a 1:1 voltage divider with R2 (on the i-modul), which results that approximately 2.5V (high) are present at the SIMPRES input. The GSM engine interprets this as "No SIMCARD" and disables the SIM supply voltage. If the switch S1 is closed, T1 blocks and SIMPRES is connected to GND (low) via R2. The GSM engine interprets this as "SIMCARD inserted" and enables the SIM supply voltage. Figure 6: Connection example for the SIMPRES input 17

18 Function Overview i-modul HSPA basic Function Overview The i-modul HSPA basic 1.0 provides you with the following functions: Automatic baud rate detection The i-modul HSPA basic 1.0 will automatically adjust the data transmission rate, if a connection is made via its serial interface.

21 i-modul HSPA basic 1.0 Operating Principle 6 Operating Principle This chapter describes the basic procedures to operate and configure an i-modul HSPA basic 1.0. In general, the i-modul HSPA basic 1.0 is configured and operated via AT commands. You can enter these commands yourself with the help of a terminal program and the AT command reference. 6.1 Used Interface The i-modul HSPA basic 1.0 is delivered with enabled serial RS232 interface by default. Alternatively, it is possible to enable the USB interface. Information about enabling the USB interface as well as required drivers for Linux and Windows can be requested from our support department under support@insys-tec.de. 6.2 Operation with the Terminal Program In general, any terminal program can be used. We recommend the program Teraterm from T.Teranishi. It is available free of cost on the Internet at You can use the program "minicom" if you work in a Linux environment. Caution! Damage of the serial interface! A possible direct connection of the serial interface of the i- modul HSPA basic 1.0 with a typical RS232 interface of a PC overloads components of the module due to the higher voltage levels. Use an RS232 level converter (e.g. MAX232) to adjust both interface types correctly. Configuring and operating the i-modul HSPA basic 1.0 with a terminal program How to configure and operate the i-modul HSPA basic 1.0 with a terminal program. The i-modul HSPA basic 1.0 is connected to the PC via a level converter or a USB connection and supplied with power. A terminal program is installed on the PC. 1. Start your terminal program. 2. Select the serial port, to which your i-modul HSPA basic 1.0 is connected. This can be a physical COM port or a virtual COM port that has been installed by the USB driver of the i-modul HSPA basic 1.0. COM1 under Windows corresponds to /dev/ttys0 under Linux. 21

22 Operating Principle i-modul HSPA basic Type the character string AT into the terminal program. Complete the entry by pressing the Enter key. Each command input starts with AT and is completed with the Enter key. The i-modul HSPA basic 1.0 replies with OK. If the i-modul HSPA basic 1.0 does not respond, this may have three probable reasons: a) the i-modul HSPA basic 1.0 is switched off or b) the i-modul HSPA basic 1.0 is not in configuration mode or c) the i-modul HSPA basic 1.0 is connected to a different serial port. Check it and repeat step Configure the i-modul HSPA basic 1.0 using AT commands. A reference of the AT commands can be found in the chapter "AT Command Reference". 5. Save your entries with AT&W. Not all configurations at the i-modul HSPA basic 1.0 need to be saved actively by entering AT&W. Some settings are automatically saved immediately. We still recommend sending the command AT&W to the i-modul HSPA basic 1.0 as your last configuration step to ensure that all settings are stored safely and are available for the next restart. 22

23 i-modul HSPA basic 1.0 Functions 7 Functions 7.1 Entering the PIN of the SIM Card The i-modul HSPA basic 1.0 requires a SIM card as well as the associated SIM card PIN to be able to log into a GSM network. The PIN is necessary that the device is able to use the SIM card for logging into the GSM network. If the SIM card requires no PIN, you don t have to enter a PIN in the i-modul HSPA basic 1.0. Note Loss of function of the SIM card! An incorrectly entered PIN can cause that the SIM card will be locked after a wrong code has been entered for three times. Take care, that the passed SIM PIN corresponds with the SIM card or disable the PIN request of the SIM card. A possibly configured PIN has no influence if the PIN request is disabled. Configuration with AT commands In order to pass the PIN, use the command Replace <PIN> with the PIN of the SIM card. In order to check the status of the PIN request between device and SIM card, use the command AT+CPIN=<PIN> AT+CPIN? The following responses inform about the status of the PIN request: No entry required PIN of the SIM card is missing PUK entry required (after repeated incorrect entry of the PIN) SIM card not or incorrectly inserted READY SIM PIN SIM PUK +CME Error: SIM not inserted 23

24 Functions i-modul HSPA basic Insert and Remove SIM Card A SIM card must be inserted that your i-modul HSPA basic 1.0 is able to log into the GSM network and transmit data. Moreover, the i-modul HSPA basic 1.0 must know the PIN of the SIM card. Insert SIM card How to insert the SIM card into the i-modul HSPA basic 1.0. You will need a SIM card. 1.

26 Functions i-modul HSPA basic Checking the Status of the GSM Login The i-modul HSPA basic 1.0 logs in into the GSM network automatically with each device restart. You can query the login status for test purposes. Then, you can determine, whether the i-modul HSPA basic 1.0 is currently logged in or not, a network search is currently performed, a login has been rejected by the GSM network, or the device is logged in into a foreign network via roaming. Configuration with AT commands In order to request the Status of the GSM login, use the command AT+CREG? The status is indicated in the response by the second figure following the comma. Response example +CREG: 0,3 The following status responses are possible: Not logged in, no GSM network search 0 Registered with the standard provider 1 Not logged in, i-modul HSPA basic 1.0 searches for GSM network 2 GSM network rejects a login 3 Registered with a foreign network via roaming 5 26

27 i-modul HSPA basic 1.0 Functions 7.4 Checking the GSM Signal Quality You can check the signal field strength at the location of the i-modul HSPA basic 1.0. The signal quality has an essential influence on the data transmission speed. If the signal field strength is too low, the transmission speed can drop severely or the connection can be terminated at all. Configuration with AT commands In order to display the signal field strength, use the command AT+CSQ The signal quality is indicated in the response by the first figure before the comma. Response example +CSQ: 13,0 The following is valid for the signal quality value: Poor reception, change location Good reception 99 Not detectable The value following the comma indicates the bit error rate. 27

28 Functions i-modul HSPA basic Establishing or Accepting a CSD Data Connection The i-modul HSPA basic 1.0 can call another modem via the GSM network and establish a CSD data connection. After dialling a phone number, the i-modul HSPA basic 1.0 synchronises with the called modem and opens a data connection with the transmission speed allowed by the GSM network. This is usually 9600 bit/s. The speed, which is set at the serial interface of the i-modul HSPA basic 1.0 at the time of connection establishment, will not be changed. All incoming characters are transmitted to the other (called) modem during the active data connection. Therefore, AT commands are not processed during a connection. The i-modul HSPA basic 1.0 must be changed to command mode again using an "Escape sequence" that it processes AT commands again during an active connection. Then, the local i-modul HSPA basic 1.0 processes the entered characters as AT commands and does not transmit them to the remote terminal. The i-modul HSPA basic 1.0 can accept an incoming connection in the same way. It answers after the configured number of ring tones and opens a connection. Configuration with AT commands In order to establish a data connection with the i-modul HSPA basic 1.0, use the command Replace <number> with the phone number of the remote terminal. If the remote terminal accepts the connection, the i-modul HSPA basic 1.0 indicates If the remote terminal accepts the connection with error correction, the i-modul HSPA basic 1.0 indicates If the remote terminal is busy, the i-modul HSPA basic 1.0 indicates If a connection to the remote terminal cannot be established, the i-modul HSPA basic 1.0 indicates An incoming call is indicated with In order to accept an incoming connection, use the command ATD<number> CONNECT CONNECT /RLP BUSY NO CARRIER RING ATA 28

29 i-modul HSPA basic 1.0 Functions In order to configure the number of ring tones after which the i-modul HSPA basic 1.0 answers and accepts the connection, use the command Replace <n> with the number of ring tones (<n> = 2 255, <n> = 0 deactivates the function). ATS0=<n> Take the AT&D setting in account. In order to change to command mode during a data connection, use the escape sequence No data must be transmitted for 1 second before and after that the i-modul HSPA basic 1.0 changes to command mode. In order to change from command mode to normal data transmission again, use the command In order to terminate a connection and cause the i-modul HSPA basic 1.0 to hang up, use the command +++ ATO ATH Terminating the connection via DTR Drop might also be possible. 7.6 Automatic Call Acceptance The automatic call acceptance enables the i-modul HSPA basic 1.0 to accept each call after the configured number of ring tones. Configuration with AT commands In order to enable the automatic call acceptance, use the command In order to disable the automatic call acceptance, use the command In order to configure the number of ring tones after which the i-modul HSPA basic 1.0 accepts the connection, use the command ATS0=1 ATS0=0 ATS=<n> Replace <n> with the number of ring tones (<n> = 2 255). 29

30 Functions i-modul HSPA basic Querying the Digital Inputs The i-modul HSPA basic 1.0 has two digital inputs (UE and UE2), whose state can be queried using an AT command. If the digital inputs are used by the application, the application must initialise the digital inputs with every start, i.e. set the respective I/O as input. Configuration with AT commands In order to initialise the digital input UE, use the command In order to initialise the digital input UE2, use the command In order to query the state of the digital inputs, use the command AT+MIOD=10,1 AT+MIOD=1000,1 AT+MIOC? The states are indicated in the response by the next to last digit <x1> for the digital input UE and the fourth from last digit <x2> for the digital input UE2. +MIOC: Response example 1,1,1,1,x2,y2,x1,y1 The following states are possible for <x>: Digital input to GND 0 Digital input open 1 30

31 i-modul HSPA basic 1.0 Functions 7.8 Setting the Switch Outputs The i-modul HSPA basic 1.0 has two switch outputs (UA and UA2), that can be controlled accordingly using an AT command. If the switch outputs are used by the application, the application must initialise the switch outputs with every start, i.e. set the respective I/O as output to a defined state. Configuration with AT commands In order to initialise the switch output UA or set it to idle position, use the command In order to initialise the switch output UA or set it to operated position, use the command In order to initialise the switch output UA2 or set it to idle position, use the command In order to initialise the switch output UA2 or set it to operated position, use the command In order to query the state of the switch outputs, use the command AT+MIOD=1,0,0 AT+MIOD=1,0,1 AT+MIOD=100,0,0 AT+MIOD=1,0,100 AT+MIOC?

37 i-modul HSPA basic 1.0 FAQ 11 FAQ Problem Possible cause Remedy The i-modul HSPA basic 1.0 does not log in. The i-modul HSPA basic 1.0 is reset during connection establishment. How can I verify that data are being transferred via a GPRS/EDGE connection? How can I verify that data are being transferred via an UMTS connection? (only with i-modul UMTS 4.1 basic) A data connection cannot be accepted with the i- modul HSPA basic 1.0. The location of the GSM antenna is improper. The PIN is not correct. The SIM card is blocked because the PIN has been entered incorrectly for several times. The SIM card is not activated. The power supply is not sufficient. The SIM card is not enabled for incoming data connections. Check the signal quality of the GSM network. Change the antenna location for a low field strength (below 12). Enter the correct PIN with the AT command AT+CPIN. The PUK must be entered to release the card again. Contact the service center of your provider. Check the power supply using the information from the Technical Data section and adjust it, if required. Display the cell information table using the command AT^SMONG and check the value in column G: G 0 GPRS/EDGE not possible 1 GPRS usage possible 2 GPRS is used 3 EDGE usage possible 4 EDGE is used Display the network operator using the command AT+COPS?. If the i-modul HSPA basic 1.0 is not logged in, only the mode will be returned. If the i-modul HSPA basic 1.0 is logged in, also the network operator and, in the last column, the access technology will be displayed. The following applies: 0 Connection via GSM 2 Connection via UMTS Prepaid cards are often not enabled for incoming data connections. Incoming CSD connection can often only be established with a mobile phone contract. Incoming IP connections (GPRS/EDGE) are usually not permitted. Contact the service center of your provider. Refer to for further information. 37

38 FAQ i-modul HSPA basic 1.0 Problem Possible cause Remedy A GPRS connection is not possible temporarily Existing GPRS connection ceases. Update of the SIM card (only with i-modul GPRS 4.1 basic) Some providers disconnect connections with no traffic for an extended period. An incoming call during an active GPRS connection interrupts the data flow. Depending on the provider, it may be possible that SIM cards are updated regularly via SMS. These updates take place automatically and can not be prevented. The AT command AT^SSTA=1,0 enables to delay the updates for 5 minutes after module start. Such disconnections can be prevented using a keep-alive function in the application, which generates regular traffic. The transmission continues after the call is finished. It may happen for extended disconnections that the connection must be re-established again. 38

39 i-modul HSPA basic 1.0 CE/EMC Compliant Integration 12 CE/EMC Compliant Integration When integrating the i-modul HSPA basic 1.0 into an application, the system integrator is responsible for the CE/EMC conformity of the entire device. In order to integrate the i-modul HSPA basic 1.0 CE and EMC compliant into your application, we recommend the following for you to observe during development Your Application The motherboard for the i-modul must be designed according to the applicable CE/EMC guidelines. Always observe short signal lines and sufficient ground surface. Connect the i-modul with a conducting spacer bolt to the device ground. If you develop a platform, which is compatible with several, different i- moduls, you must maintain the respective design criteria for each i-modul (especially concerning the phone connection). The PCB tracks to the i-moduls with network interfaces, like Modem, ISDN, and Ethernet, must be designed with a track distance of 2.5 mm between the tracks of the network interface and all other signals (refer to EN60950) Application Interface / Terminal Strip P1 The TTL RS232 interface should be equipped with ferrite beads directly at the module to reduce interference signals from the motherboard. It is also beneficial to design capacitors (preferably SMD) at all RS232 and I/O signal lines to GND, which can be equipped when needed. Short lines to the connector and good ground are important. The recommended value for capacitors is 22 pf to 47 pf Network Interface / Terminal Strip P2 (for Modem /ISDN) The line to the network interface (line from i-modul to device socket) should be as short as possible and not be routed close to sources of interference (e.g. switching power supplies). Provide the line with ferrite beads directly at the device socket. The phone interface (not for i-modul with Ethernet interface) should be provided with standard ferrite beads (e.g. Murata BLM31A601SPT or Würth Elektronik type ) and with optional ceramic capacitors (100 pf/2 kv, Y2 standard) to ground. In case of extended requirements to the interference resistance of the phone line (especially burst), a current compensated impedance (e.g. Epcos B82790-C2475-N340 or Würth Elektronik type ) can be used. The strip conductors on the Ethernet side should have a wide design (minimum 24 mil). 39

40 CE/EMC Compliant Integration i-modul HSPA basic 1.0 Ethernet receive PCB tracks must provide a minimum width of 25 mil, Ethernet transmit PCB tracks a minimum width of 100 mil (1 mil mm). The PCB tracks must be routed parallel and have the same length Antenna Connection (if equipped) The antenna connection must be connected to ground and a ferrite ring must be installed behind the ground connection (towards i-modul) to increase the interference resistance against burst and ESD at the antenna connection Further Recommendations The required measures will mostly depend on the connections and the layout (especially of the ground surfaces and good ground connections) of the motherboard. To save costs, some of the above mentioned capacitors or ferrite beads may be omitted. However, they should be considered in the layout to be able to integrate it without having to change the PCB, if the EMC tests show that these components are necessary. For the Ethernet module, insert bridges instead of the ferrite beads, while the ceramic capacitors remain unequipped Reference Documents Our evaluation board may be helpful for designing your application.

Possible offence against approval regulations. If the final product is not approved in the U.S. territories, the application manufacturer shall take care that the 850 MHz and 1900 MHz frequency bands be deactivated and that band settings be inaccessible to end users. If these demands are not met (e.g. if the AT interface is accessible to end users), it is the responsibility of the application manufacturer to always ensure that the application be not exported to countries within the area of validity of the FCC. 40
