    on the download area of the FALCOM website.

    1.1 General

    FALCOM is providing all kinds of GPS and Telematics products as required by the

    market today. The new DISCO-B4 is an unique, low-cost and weatherproof device that

    uses a quad-band GSM/GPRS technology for two way communication and the latest

    GPS technology for positioning. The DISCO-B4 comes with a protection class IP6K9K

    ideal for applications with extreme environmental conditions. This protection class

    IP6K9K allows the device to be mounted on an exterior surface of the vehicle. The

    DISCO-B4 device comprises an embedded configurable software that provides even

    greater performance and flexibility for its users and system integrators to develop high-

    performance applications that allow vehicle tracking via SMS and over the Internet.

    The device concept is targeting for direct implementation as a mobile client in a wide

    range of high volume, low-cost flexible system solutions like AVL, fleet management,

    vehicle security and recovery and other related areas. The configuration of the DISCO-

    B4 can be done via local serial link or remotely via SMS or TCP/Internet. The tracking

    functionality of the embedded mobile client application is combined with a variety of

    alert messaging capabilities. The configurable alert messages contain current position

    and status report and use 3 multi-function I/O. In addition to that two predefined digital

    inputs are detecting ignition line status and main power (car battery) failure, so you

    may handle these events and use as notification.

    By default, DISCO-B4 is offered without an internal battery. Should you need a

    DISCO-B4 device with an internal battery, please see “Ordering Guide” and

    choose one which meets your application requirements.

    The embedded software can be controlled by word like “PFAL” commands needed

    for executing particular actions, reading or setting particular configurations. These

    commands are valid for all kinds of operation channels including Serial, SMS, CSD, TCP

    and SMTP.

    DISCO-B4 provides Geofence features for territory management, route verification,

    prohibited locations, parking area and more, with exception reporting to a wide variety

    of events such as arrivals, departures, deliveries, pick-ups, illegal entries, unauthorized

    movement, etc. DISCO-B4 contains a data-logger (history feature) that enables you to

    archive unique vehicle locations in sequence for up to 45 days for later analysis and

    evaluation (for example, archive interval up to 20 sec.).

    The physical interface to the device application is made through an integrated 8pin

    connector. It is required for controlling the device, receiving GPS location data,

    transferring data and providing automotive power supply lines. This connector provides

    1 serial interface giving you maximum flexibility for local use. A separate 4pin double

    row connector (containing RX, TX, GND and VOUT - on STEPPIII known as second serial

    interface) is for connecting a MFD device and two separate audio jacks for directly

    connecting an active speaker and a microphone.

    2 SECURITY

    IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM, READ

    THIS INFORMATION BEFORE USE!

    Your cellular engine DISCO-B4 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.

    This chapter contains important information for the safe and reliable use of the

    DISCO-B4 device. Please read this chapter carefully before starting to use the

    cellular engine DISCO-B4.

    2.1 General information

    Your DISCO-B4 device utilizes the GSM/GPS 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 DISCO-B4 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.

    SIM cards are needed for the use of the acquired devices, which are not included

    in the scope of delivery of the device. The SIM cards can be acquired e.g. by

    specific providers. Additional costs can result from the use of the SIM cards which

    are to be borne by the purchaser (client) of the devices. The seller does not cover

    the extra costs for the use of the devices. The seller gives no recommendation for

    the use of specific SIM cards and is not liable for the fact that the devices are

    usable with all available SIM cards. The seller is also not liable for any other costs

    that are needed for the application of the customer in connection with this device.

    2.2 Exposure to RF energy

    There has been some public concern about possible health effects when using

    GSM modems. 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

    minimize 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 guidelines below.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    2.3 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 DISCO-B4 while driving, please

    pay 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!

    2.4 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.

    2.5 Vehicle electronic equipment

    Check your vehicle manufacturer’s representative to determine if any on board

    electronic equipment is adequately shielded from RF energy.

    2.6 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 DISCO-B4 device 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.

    2.7 Aircraft

    Turn your DISCO-B4 OFF before boarding any aircraft. Use it on the ground only with

    crew permission. Do not use it 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.

    2.8 Children

    Do not allow children to play with your DISCO-B4 device. 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.

    2.9 Blasting areas

    To avoid interfering with blasting operations, turn your device OFF when in a

    “blasting area” or in areas posted: „turn off two-way radio“. Construction crew

    often uses remote control RF devices to set off explosives.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    2.10 Potentially explosive atmospheres

    Turn your DISCO-B4 device OFF when in any area with a potentially explosive

    atmosphere. It is rare, but your modems or their 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.

    4.2 NMEA data message

    DISCO-B4 delivers data in the NMEA-0183 format. Table below lists the NMEA and

    FALCOM output messages supported by the DISCO-B4 device and gives a brief

    description for each protocol. For further description about these protocols, refer to

    the related documents [1].

    The running firmware inside the device offers the possibility to switch on and off

    each protocol that is listed in the table below. As mentioned above the firmware

    inside the device supports a lot of PFAL commands enabling full control of the

    device. There are also PFAL commands which allow sending of these protocols via

    SMS, TCP, Data call and e-mail. For example, the PFAL commands

    "PFAL,GSM.SMS.Send..." and "PFAL,GSM.Send.TCP..." allow you to send an SMS

    message to a user or a TCP packet to a TCP server to let him know the current

    location, GPS state, UTC time, Date, Speed and Course over ground of the device.

    The received SMS contents or TCP packet can then be forwarded to a map

    software for graphical representation of the device location. When you install such

    a device in a vehicle, you are then able to have always full control of the vehicle.

    In this way you will know where your vehicle is, what is happening with your vehicle,

    has your vehicle been moved without authorization from a park area, real time

    vehicle movements and more. The TCP server developed by FALCOM called

    "Trace4You" has a lot of such features allowing you to have full control of your

    vehicle, fleet and other assets.

    5 DISCO-B4 APPLICATION INTERFACE

    5.1 Power supply

    The power supply for the DISCO-B4 unit has to be a single voltage source of V

    +IN

    =

    +10.8 V...+32.0 V DC. The operating voltage (V+IN) has to be permanently applied

    to the DISCO-B4 unit and able to provide sufficient current of up to 1.9 A.

    The operating voltage (V

    +IN

    and GND) is protected against voltage spikes and reverse

    polarity, but not against continuous-overvoltage.

    NOTE: Operating voltage range must never be exceeded; care must be taken in

    order to fulfill min/max voltage requirements.

    5.1.1 Power supply pins (1 and 2) on the 8-pin connector

    One +IN pin on the 8-pin double row connector is dedicated to connect the supply

    voltage, and the GND pin for grounding.

    Both +IN and GND pins serve for charging the internal Li-Polymer battery

    (option) and powering the DISCO-B4 device. DISCO-B4 has an automatic

    power ON-function when external power is applied. The power supply for the

    DISCO-B4 is capable of utilizing current ranging from V

    +IN

    =+10.8 V... +32.0 VDC

    designed for automotive application.

    Signal name I/O Parameter Description

    +IN I +10.8 V...+32.0 VDC. The

    operating voltage must never

    be exceeded.

    Positive operating voltage.

    For security reason, it is recommended to integrate

    externally a 2A fuse link between interconnection plug (8-

    pin connector) and d.c.-power source (see Fig 15).

    GND - 0 V Ground

    5.1.2 Automatic shutdown

    Automatic shutdown takes effect if:

    • battery voltage level runs low and external power supply is

    disconnected.

    • supply voltage is below the specified input voltage range.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    5.1.3 Power saving

    SLEEP mode reduces the functionality of the modules of the DISCO-B4 device to a

    minimum and thus minimizes the current consumption to the lowest level. Settings

    can be made using the $PFAL,Sys.Device.Sleep command. For details, see

    example in table below.

    Following SLEEP modes are supported by the DISCO-B4 device:

    Modes Description

    IGN

    Device goes to sleep and wakes up when IGN (pin 3 - blue color) changes its digital

    level from Low to High (performs a rising edge).

    Ring

    Device goes to sleep and wakes up when the GSM module receives a voice call or

    an SMS.

    Timer=1:20:00

    Device goes to sleep and wakes up after the defined time has expired.

    Motion=5,20,20

    Device goes to sleep and wakes up when motion is detected.

    ExtPwrDetect

    Device goes to sleep and wakes up when external power (higher than 9 V) is

    connected to the device.

    ExtPwrDrop

    Device goes to sleep and wakes up when external power is disconnected or it drops

    below 8 V.

    AiWu=5.1,12

    Device goes to sleep and wakes up when the voltage on I/O1 (pin 4 used as analog

    input) exceeds the defined upper or lower threshold.

    Example $PFAL,Sys.Device.Sleep=IGN+Ring+Timer=1:20:00

    IMPORTANT: The sleep and wake-up procedures are quite different depending on

    the selected sleep mode. Please keep in mind that the power

    saving with "Ring" parameter works properly only when PIN

    authentication has been done and the device is already registered

    in the GSM network. If you attempt to activate power saving while

    the device is not registered in the GSM network, the SIM card is not

    inserted or the PIN not correctly entered, the device responds with

    an error "ring shutdown aborted due to bad GSM coverage" and the

    power saving does not take place. For more details, refer to the

    manual "steppIII_FOX-LT_bolero_lt_PFAL_Configuration_Command_Set.pdf".

    NOTE (This note is related to the battery-powered devices only): The internal battery of

    the DISCO-B4 must have enough power to safely wake up the device from a sleep

    mode. If the internal battery of the DISCO-B4 device does not have enough power,

    the device cannot complete the wake up operation.

    5.2 Determining the External Equipment Type

    Before you connect the serial port pins on the aforementioned terminals (DCE units)

    to external equipment, you need to determine if the external hardware serial ports

    are configured as DTE or DCE.

    DISCO-B4 is designed for use as a DCE device. Based on the aforementioned

    conventions for DCE-DTE connections, it communicates with the customer

    application (DTE) using the following signals:

    DISCO-B4 Terminal (DCE) to Application (DTE)

    RxA <---------- TXD

    TxA ----------> RXD

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6.1.2 Special pin description (Pins 4, 5, 6)

    These pins have dual functions. All of them are controlled by the internal firmware of

    DISCO-B4. Therefore, the user must specify whether they will be as analog or digital pins.

    This function is controlled by the command PFAL,IO0[1,2].Config. If, for example, you

    want to use I/O1 as an analog pin, and the I/O2 and I/O3 as digital, the command

    settings would look like this:

    PFAL,IO0.Config=AI,2,11 //0 = I/O1; AI = analog; 2 and 11 = min. and max.

    voltages for Low and High events.

    PFAL,IO1.Config=DI,5,10 //1 = I/O2; DI = digital; 5 and 10 = min. and max.

    voltages for Low and High events

    If a pin from I/O1 to I/O3 is configured as a digital pin, then the pin must be assigned as

    an input or an output. If you want I/O2 to be an input and I/O3 to be an output, the

    command settings would look like the following:

    PFAL,IO1.Config=DI,5,10 //1 = I/O2; DI = digital; 5 and 10 = min.

    and max. voltages for Low and High

    events.

    PFAL,IO6.Set=high[low,hpulse,lpulse,cyclic] //6 = I/O3; high = sets output to high.

    Some examples how to use them are given in sections below.

    When using an I/O as digital you must set it to high first (with PFAL command

    “$PFAL,IO4[5,6].Set=high”), otherwise 0V will be measured (and the device could be

    damaged).

    6.1.2.1 How to use them as analog inputs

    Because these pins can operate either as digital or analog, they have to be configured

    and calibrated with PFAL commands before using them.

    Analog voltages of up to 32.0V with a 10 bits resolution can be processed and remotely

    evaluated by a server application. A pull-up resistor to a constant input voltage allows

    for resistive transducers to ground, e.g. fuel sensor or thermistors.

    To use these IOs as analog, the following command should be set to the device.

    PFAL,IO0[1,2].Config=AI,2,11

    where 0, 1 and 2 are indices corresponding to IO1 (pin 4), IO2 (pin 5) and IO3 (pin 6)

    respectively. While the value 2 and 11 are min. and max. voltages that will be used to

    generate Low and High events, respectively.

    Detailed information can be found in software manual “steppIII_FOX-

    LT_bolero_lt_PFAL_Configuration_Command_Set.pdf“.

    ↓ Connection example 1 (for I/O1 and I/O2):

    An analog input can be connected to a temperature sensor (a NTC resistor for

    instance). In the diagram below is used a fixed resistor is used from the input

    voltage to the I/O 2, and a variable resistor (Negative Temperature Coefficient -

    whose resistance or capacitance decreases when temperature increases) to ground.

    It is possible to set a low temperature alarm and a high temperature alarm.

    Passage through these thresholds will trigger an alarm. We recommend to use

    SMS or TCP as alarm type with GPIOP protocol. The SMS can be received on a

    mobile phone, modem or any GSM device when changes are detected. The

    analog-to-digital converter (ADC) inside the unit has an input voltage range

    from 0 to 2.5 V. An application example is shown in figure below:

    ↓ Connection example 2 (for I/O1 and I/O2):

    An analog input can be connected to a tachometer generator. The

    maximum output voltage of the tachometer should be + 32.0 V (see

    illustrated example in figure below).

    Both circuit examples (the NTC diagram above and the Tachometer below) are only

    illustrations to show the aim of these I/Os when used as analog inputs.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6.1.2.2 How to use these pins as digital Inputs (Pin 4, 5, 6)

    These pins are high active when used as digital inputs, so you can set V

    IN(LOW)

    and

    V

    IN(HIGH)

    to any levels within the range from +0 to +32.0 VDC. The High and Low levels

    can be set with PFAL command (e.g. PFAL,IO0[1,2].Config=DI,5,10) - where 0, 1 and 2

    are indices corresponding to IO1 (pin 4), IO2 (pin 5) and IO3 (pin 6) respectively. While

    the values 5 and 10 are min. and max. voltages that will be used to generate Low and

    High events respectively. Detailed information can be found in software manual

    “steppIII_FOX-LT_bolero_lt_PFAL_Configuration_Command_Set.pdf“.

    The figure below illustrates how these inputs can be used in practice. When the internal

    software detects input changes from High to Low or vice versa, a Falling or Rising edge

    Event is respectively generated. Therefore, depending on the alarm type, the DISCO-

    B4 can react to the input changes and release different alarms such as sending out an

    SMS, email message, TCP packet, opening a CSD connection or activating an output

    port. The alarm type is user-dependant.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6.1.2.3 How to use these pins as digital outputs (Pin 4, 5, 6)

    The DISCO-B4 device supports three IOs which can be used either as input or

    output. These outputs are open collectors. They can be directly connected via

    resistors (R) to LEDs, Relays etc., which need no more than 100 mA @ up to + 32.0 V DC.

    The figures below show the schematic of possible output connections. To use and

    activate these outputs use the command $PFAL,IO4[5,6].Set=high[low,hpulse,lpulse,

    cyclic] for IO1, IO2 and IO3 respectively or you can configure one or more alarms that

    activate these outputs when specific events occur (e.g. PFAL,Cnf.Set,AL0=IO.e8=redge:

    IO4.Set=cyclic,1000,2000).

    In order to evaluate this alarm, first send this configuration to the DISCO-B4 device and

    then trigger IGN-pin to High – as result the IO1 goes High for 1 sec and Low for 2 sec. To

    set IO1 to Low, just execute the command PFAL,IO4.Set=Low. For more details how to

    activate an output and how to configure an alarm, refer to the manual

    “steppIII_FOX-LT_bolero_lt_PFAL_Configuration_Command_Set.pdf“. Both figures

    below show the schematic connections of how to use this output. Please note: do

    not apply power directly to an output pin without having a device (e.g. a resistor)

    between the output pin and external power.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6.1.2.4 How to use IGN pin(pin 3)

    The IGN-pin has two functions:

    ✔ It wakes up the system DISCO-B4 from the IGN-sleep mode (when

    sleeping),

    ✔ and can be used to monitor the vehicle ignition state, to report/store the

    START and STOP of a trip by using the events IO.e8=redge and IO.e8=fedge

    for START and STOP respectively.

    IGN-sleep mode is one of the eight supported energy-saving modes of operation in

    which all unnecessary components are shut down. Once the device is awakened by

    IGN high signal, it returns to full functionality.

    Note that, the DISCO-B4 device powers on automatically when external power is

    applied, and IGN pin provides an additional “wake up” function for the IGN-sleep

    mode when it is requested.

    Using IGN pin you can configure the system to store a specific location or to deliver

    an alarm SMS or TCP packet if an unauthorised entry to start your vehicle is

    attempted. In such a case use the IGN generated event as a condition to start vehicle

    tracking.

    NOTE: All battery powered DISCO-B4 devices are shipped into the IGN-sleep mode. Therefore, to wake

    up the device, connect the IGN-line to the d.c.-power source.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6.1.2.5 Serial communication signals (RxA and TxA)

    The DISCO-B4 device incorporates a full duplex serial channel which allows two

    devices to communicate directly with each other via the RS232 serial port. All

    supported variable baud rates are software-controlled. It is recommended to use

    the DISCO-B4 Evalboard in order to communicate with the DISCO-B4 device, as

    there you will find all you need to evaluate with it.

    This serial channel (RxA, TxA) operates at ±12 V signal level according to the V.24.

    The signals on these pins are obtained to RS232 compatible signal levels.

    RxA This is the main receiving channel and is used to receive

    software commands to the board from any software (e.g.

    HyperTerminal). Moreover, the firmware update can also be

    done through this serial port.

    TxA This is the main transmitting channel and is used to output

    navigation, measurement, response and system data to

    any software (e.g. HyperTerminal, FALCOM Workbench).

    You may connect this port to a Bar code scanner and with the help of the serial

    event Sys.eSerialData0 you may process the incoming data from a scanner.

    Moreover, the incoming data on the serial line may be forwarded/sent via TCP to

    an internet server and there processed/stored into a database. Therefore, you have

    this data in real-time irrespective in which country they have been scanned. The

    interface type and port settings of the bar code scanner must be compatible with the

    DISCO-B4 one. For more information how to implement such an application, refer to the

    application note "AppNotes_connecting_a_bar_code_scanner_to a_STEPPII.pdf".

    6.2 Insert the SIM card holder inside the device

    The DISCO-B4 device is equipped with a GSM modem. To use it, you must insert a

    SIM card in the appropriate holder inside the device. There is no SIM card shipped

    with the unit. The customers must provide their own SIM card for use. The unit has

    altogether 12 screw holes. Because the SIM card must be inserted by the customers

    only 2 screws are screwed on.

    Attention: The opening and closing of the housing must be performed by

    qualified electricians.

    The SIM card is obtained from your mobile provider and must be activated for GSM

    data services before using it. Together with the SIM card, you receive a 4-digit PIN

    number. Entering of the PIN allows your device to access the mobile network.

    To insert the SIM card into the SIM card holder inside the device, follow the steps

    below:

    1) Remove the power supply and any other connections from the device, then

    place the device on the back. The housing has been screwed down by only 2

    screws for quick opening and inserting the SIM card. These are located opposite

    to each other on the housing ring. Unscrew these 2 screws (1), (2) by using a Torx

    T6 Screwdriver. In the delivered package there are also 10 other screws which

    should be used to assemble the housing after inserting the SIM card.

    2) After unscrewing both screws, carefully open the housing cover (3) by using your

    fingernails and then pull them apart using your finger. If you cannot open the

    case with your fingernails, then use a flat non-metal object. The case has a black

    rubber ring around the lower case of the housing which is advertised to make the

    device whether proof. Improper handling of this rubber ring can lose the whether

    proof capability of the the device housing.

    Attention: Do not remove any of the cable connectors inside the device case!

    3) Locate the SIM card holder (4) on the side where the PCB revision ID is shown.

    Push the slider (metal lock) of the SIM card-holder (4) in the direction marked “-

    >OPEN”. Flap the card-holder up. Insert the SIM card into the SIM card-holder

    (with care not to damage any components of the circuit board) - the bevelled corner on

    the SIM card is facing toward the top of the card-holder and the golden contact

    area is facing downwards when the holder closes. Push the SIM card down until it

    8 APPENDIX

    8.1 Schematics

    The figure below illustrates a common schematic when you install your DISCO-B4

    hardware in the vehicle and use it for vehicle security. For detailed information,

    please, refer to the related documents [InVehicleMounting.pdf].

    8.1.1 Installation guidance for 8-pin connector

    On the top of the schematic you can find the corresponding pin out of the 8pin

    double row connector.

    When installing your DISCO-B4 you will not only be able to track and locate objects

    all the time, but you will also be automatically notified when disagreements occur

    between the configuration and device behaviours themselves. Depending on your

    application requirements, the I/O pins can be configured and used as digital

    outputs to lock/unlock vehicle doors, to activate a relay, buzzer, turn on a lamp; or

    as digital inputs to detect when something in the vehicle is opened or closed. Input

    changes may trigger an output to high or low. The IGN line can be connected to

    the vehicle ignition key to monitor its ON/OFF position.

    Note: Turn car ignition off before making any connection. Use a common ground

    point for all ground wires. To avoid ground loops, isolate all ground pins of

    the DISCO-B4 unit from the vehicle body. Do not connect power from a

    different system to the DISCO-B4.

    Software configured outputs of the DISCO-B4 must operate at the same

    voltage level as the supply voltage +IN operates.

    The operating voltage range must NEVER be exceeded as device is not

    protected again continuous overvoltage. For security reasons it is

    recommended to integrate externally a 2A fuse link between the positive

    wire of the DISCO-B4 (+IN) and d.c. - power source.

    The device should be mounted in the dash or on the windshield of the vehicle

    with the GPS side facing the sky and the antenna has a clear view to the sky.

    Connect the power cable to the DISCO-B4. With the vehicle ignition off and

    antenna connected, attach the power pins to DISCO-B4 (FIRST connect

    the GND pin and then the +IN pin).

    8.2 Setting up DISCO-B4-EVALKIT

    To get started quickly with DISCO-B4 EVALKIT, follow the steps below:

    1) Connect the 8pin single row connector on the external cable to the 8pin single

    row connector socket on the evalboard. To remove it press the "lever" on the back

    of connector and then pull it out.

    2) Plug the RS232 serial cable into a free COM port on your PC.

    3) Plug the other end of the RS232 serial cable into the 9pin serial port on the

    evalboard.

    4) Plug the AC adapter into the wall socket of your 220V electric mains.

    5) Plug the 4pin connector on the “PS-002-N/JP3” power adapter into the left input

    socket on the evalboard marked "POWER 10.8 V …32 V”.

  • DISCO-B4 HARDWARE MANUAL VERSION 1.0.3

    6) On the evalboard, turn the switches marked “E/ON”, “D/ON”, “IGN” to ON and

    “Current” to CURRENT.

    “E/ON” Supplies power to the DISCO-B4 evalboard.

    “D/ON” and “Current” Supplies power to the DISCO-B4 device.

    “IGN” Switches DISCO-B4 from IGN-sleep mode to full functionality

    (Battery powered FOX devices are shipped by the factory in IGN

    sleep mode. Therefore, the device requires a Low to High signal

    on IGN-pin to be activated).

    Figure 18: Turn on switches on the the evalboard

    8.3 What should be considered when using the DISCO-B4

    device

    DISCO-B4 is a device controlled by PFAL commands in the operating firmware.

    Therefore, in order to create application with the DISCO-B4 device and to obtain

    maximum benefit from the DISCO-B4 operating firmware, you have to build a

    specific configuration inside the device. All PFAL commands can be sent to the

    DISCO-B4 with the help of the Workbench software which can be free of charge

    from the FALCOM's website (http://www.falcom.de). The commands supported by

    DISCO-B4 and other AVL devices are available in the manual

    “SteppIII_fox_bolero_lt_PFAL_Configuration_Command_Set.pdf”.
