2 SECURITY

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

INFORMATION BEFORE USE!

Your cellular engine DISCO-B4-GLONASS 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-

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

2.1 General information

Your DISCO-B4-GLONASS 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-GLONASS 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.

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-GLONASS 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!

DISCO-B4-GLONASS HARDWARE MANUAL VERSION 1.0.3

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-GLONASS 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-GLONASS 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 crew­member 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-GLONASS 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.

2.10 Potentially explosive atmospheres

Turn your DISCO-B4-GLONASS 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-GLONASS delivers data in the NMEA-0183 format. Table below lists the NMEA and
FALCOM output messages supported by the DISCO-B4-GLONASS 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,TCP.Client.Send..." 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
be forwarded to a map software for locating the device graphically on it. When you install such a
device in a vehicle, you are 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.

5.1.3 Power saving

SLEEP mode reduces the functionality of the modules of the DISCO-B4-GLONASS device to a
minimum and thus minimizes the current consumption to the lowest level. Settings for activating
one of the supported low power modes 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-GLONASS 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-GLONASS must have enough power to safely wake up the device from a sleep mode. If the
internal battery of the DISCO-B4-GLONASS 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-GLONASS 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-GLONASS 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-B4­GLONASS. 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_FOX­LT_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:

Figure 4: An example block diagram of I/O2 when used as analog input.

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-GLONASS 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-GLONASS 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-GLONASS 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-GLONASS 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-GLONASS device and
then trigger IGN-pin to High – as result the IO1 goes High for 1 sec and Low for 2 sec. To set input 1
(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_FOX­LT_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.

6.1.2.4 How to use IGN pin(pin 3)

The IGN-pin has two functions:

✔ It wakes up the system DISCO-B4-GLONASS 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-GLONASS 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-GLONASS 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-GLONASS HARDWARE MANUAL VERSION 1.0.3

6.1.2.5 Serial communication signals (RxA and TxA)

The DISCO-B4-GLONASS 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-GLONASS Evalboard in order
to communicate with the DISCO-B4-GLONASS 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-GLONASS 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".

6.1.3 4pin row connector

This interface is used to connect a MFD device to the DISCO-B4-GLONASS. The pin out is given in
table below.

6.2 Insert the SIM card holder inside the device

The DISCO-B4-GLONASS 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 by making sure that no damages can occur. 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 stops. Make sure, that the SIM card properly fits in
the SIM card-holder.

4) Flap the card-holder back (without force), then press the slider (metal lock), and at the

same time move it in the direction marked "<- LOCK" on the card- holder until it stops (5).

DISCO-B4-GLONASS HARDWARE MANUAL VERSION 1.0.3

Figure 11: Removing crews around the housing, opening the cover, inserting the SIM card into

the SIM card holder and screwing the housing again.

5) Clean the O-ring (the black rubber ring that goes around the lower case). To maintain the life of

the O-ring we recommend to grease it with silicone "e.g DC4" before closing the case .

Hint: When opening a DISCO-B4 device, the O-ring rubber has to be removed and replaced by a
new one. The O-ring rubber must be greased using silicone "e.g DC4". For each device you need
5g silicone DC4 for greasing the O-ring. We strongly recommend an annual replacement of the O­ring rubber. Don't use the old O-ring rubber anymore. How to replace the O-ring, refer to the
chapter Fehler: Referenz nicht gefunden.

6) Now, hold the lower case in your left hand with the battery showing the left side and the cover in

your right hand as shown in figure above (6). Then place the cover back on to the lower case (7)
by ensuring first that the holes at the outer edge of the upper and lower case s fit exactly to each
other as if both cases fit in place it is not possible to rotate the cover.

7) Finally, press smoothly both cases (8) with your hands with care not to damage the black O-ring

and then screw in all 12 screws (included) on the 12 small holes of housing (see below) using the
Torx T6 Screwdriver. Be careful not to over-tighten these screws as this could damage the device
housing. The maximum tightening torque used on the Torx screws must not exceed the
maximum value of 0.6 Nm, recommend 0.5 Nm.

6. Take the device upper case (cover) and clean the inner edge of cover and grease it
around also with a little silicone on your forefinger.

7. Place the lower case on the left side and keep the cover on the right hand with two
marked pins, see figure above (7), parallel to the antenna board. Otherwise, the cover
can not be closed.

8. Place the upper case (cover) onto the lower case so that the holes at the outer edges
of both cases fit exactly to each other. Press smoothly both cases with your hands until
they fit together with care not to damage the O-ring.

9. Finally, clean the rest of silicone around the device case and then assemble the other parts
together.

6.2.2 How to enter the SIM card PIN:

To insert the PIN of the SIM card follow the steps below:

1) Install and start the FALCOM Workbench software.

2) Connect your DISCO-B4-GLONASS to a free PC COM port (see chapter 6.1.2.5) and power up
your device (see chapter 6.1).

3) Open a COM Port, a Console and an Editor. Select the COM port and port settings (57600
bps, 8 Data bits, No Parity bit, 1 Stop bit, None Flow control) and then click on the Connect
icon on the left of the text "Port", to connect to. Connect the Console to the COM Port and
the Editor to the Console on the Connection view. For more details refer to the Workbench
User's Guide.

4) Finally send from the editor the command "$PFAL,Cnf.Set,GSM.PIN=xxxx" (xxxx = PIN of your
SIM card). For more details refer to the manual “SteppIII_FOX-
LT_bolero_lt_PFAL_Configuration_Command_Set.pdf”.

6.3 Mounting

The DISCO-B4-GLONASS device should be mounted on an exterior flat surface of a vehicle

8.1 Schematics

The figure below illustrates a common schematic when you install your DISCO-B4-GLONASS
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-GLONASS 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-GLONASS
unit from the vehicle body. Do not connect power from a different system to the
DISCO-B4-GLONASS.

Software configured outputs of the DISCO-B4-GLONASS 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-GLONASS (+IN) and d.c. -
power source.

The device should be mounted on an exterior flat surface of a vehicle such as
the roof with the GPS side (top side) facing the sky.

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

antenna connected, attach the power pins to DISCO-B4-GLONASS (FIRST connect the
GND pin and then the +IN pin).

8.2 Setting up DISCO-B4-GLONASS-EVALKIT

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

1) Unpack the unit and the Evalboard from the Kit and connect the 8pin single row connector on the

external cable of the DISCO-B4-GLONASS unit into the 8pin single row connector socket of the
evalboard. To remove it press the "lever" on the back of connector and then pull it out.

2) Unpack the RS232 serial cable from the Kit and plug it into a free COM port on your PC.

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

4) Unpack the AC adapter from the Kit and plug it into the wall socket of your 220V electric mains.

5) Unpack the “PS-002-N/JP3” power adapter and plug the 4pin connector of this adapter into the left

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

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-GLONASS evalboard.

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

“IGN” Switches DISCO-B4-GLONASS 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).

8.3 What should be considered when using the DISCO-B4-GLONASS
device

DISCO-B4-GLONASS is a device controlled by PFAL commands in the operating firmware. Therefore,
in order to create application with the DISCO-B4-GLONASS device and to obtain maximum benefit
from the DISCO-B4-GLONASS operating firmware, you have to build a specific configuration inside
the device. All PFAL commands can be sent to the DISCO-B4-GLONASS 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-GLONASS and other AVL devices
are available in the manual “AVL_PFAL_Configuration_Command_Set.pdf”.
