This product manual is only addressed to qualified personnel which is well
skilled in electronical/electrical installation and not addressed to private
consumers/end users. The installation, implementing or setting into operation
of the product can only be performed by this qualified personnel.
1.1 General
This description is focused on the GSM/GPRS and GPS terminal STEPPIII from
FALCOM GmbH. It contains information about purpose and use of the
STEPPIII concept.
In order quickly to start and immediately and comprehensive to use all
functions and to avoid any mistakes of STEPPIII terminal on your utilization, we
recommend to read the following references and suggestions for using your
new STEPPIII terminal.
The
STEPPIII
concept
represents
further
development
of
the
FALCOM STEPP and STEPP II concept. The new device can be easily
integrated into existing STEPPII designs or into a variety of new applications. It
is functional, mechanical and software compatible to the popular
STEPPII-55/56-GPRS device family.
Compared to previous STEPP and STEPP II terminals the new STEPPIII concept
embeds Quad Band GSM/GPRS core, high-sensitivity 20-channel GPS core,
3D-motion sensor, 1100 mA/h Li-Polymer battery.
The STEPPIII terminal is a Plug & Play GSM/GPRS/GPS terminal with an
embedded configurable software that provides even greater performance
and flexibility for its users and system integrators to develop highperformance applications. STEPPIII is a completely self-contained and
battery-powered system with a stand-alone software that provides locationbased applications. It is designed for indoor fixed mounting. 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 area. The
tracking functionality of the embedded mobile client application is
combined with variety of alert messaging capabilities. The configurable alert
messages contain current position and status report and use 2 digital inputs,
4 analog or digital inputs and 4 digital outputs as hardware back-bone.
Depending on how the system is set up, 4 digital outputs allow remote
control of external actuators. In addition to that two predefined digital inputs
are detecting ignition line and main power (car battery) failure, and so you
may handle these events and use as notification. Nevertheless, if the external
power source fails, the internal rechargeable 1100 mA Li-Polymer battery
provides continuous operation for about 10-12 hour after full charged
(configuration dependent).
The embedded software comprises a set of word-like commands termed
“PFAL” needed for executing particular actions, reading or setting particular
configurations. These commands are valid for all kinds of operations
including SMS, CSD, TCP and SMTP.

2 SECURITY
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM,
READ THIS INFORMATION BEFORE USE!
Your cellular engine STEPPIII 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 STEPPIII. Please read this chapter carefully before starting to use the
cellular engine STEPPIII.
2.1 General information
Your STEPPIII device utilizes the GSM/GPRS/GPS standard for cellular
technology. GSM/GPRS is a newer radio frequency („RF“) technology than
the current FM technology that has been used for radio communications for
decades. The GSM standard has been established for use in the European
community and elsewhere. Your modem is actually a low power radio
transmitter and receiver. It sends out and receives radio frequency energy.
When you use your modem, the cellular system handling your calls controls
both the radio frequency and the power level of your cellular modem.
For the use of the acquired devices SIM cards are needed, which are not
included in the scope of delivery of the device. The SIM cards can be
acquired e.g. by specific providers. From the use of the SIM cards can result
additional costs, 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
does not liable also for the fact that the devices are usable with all available
SIM cards. The seller also covers no 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 of using a
GSM modem. Although research on health effects from RF energy has
focused for many years on the current RF technology, scientists have begun
research regarding newer radio technologies, such as GSM. After existing
research had been reviewed, and after compliance to all applicable safety
standards had been tested, it has been concluded that the product is fit for
use.
If you are concerned about exposure to RF energy there are things you can
do to 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.

Page 10
STEPPIII Hardware description
Version 1.0.0
2.3 Efficient modem operation
In order to operate your modem at the lowest power level, consistent with
satisfactory call quality please take note of the following hints.
If your modem has an extendible antenna, extend it fully. Some models allow
you to place a call with the antenna retracted. However, your modem
operates more efficiently with the antenna fully extended.
Do not hold the antenna when the modem is „IN USE“. Holding the antenna
affects call quality and may cause the modem to operate at a higher power
level than needed.
2.4 Antenna care and replacement
Do not use the modem with a damaged antenna. If a damaged antenna
comes into contact with the skin, a minor burn may result. Replace a
damaged antenna immediately. Consult your manual to see if you may
change the antenna yourself. If so, use only a manufacturer-approved
antenna. Otherwise, have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorized antennas,
modifications or attachments could damage the modem and may
contravene local RF emission regulations or invalidate type approval.
2.5 Driving
Check the laws and regulations on the use of cellular devices in the area
where you drive. Always obey them. Also, when using your modem while
driving, please 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 fulfill road-safety instructions of the
current law!
2.6 Electronic devices
Most electronic equipment, for example in hospitals and motor vehicles is
shielded from RF energy. However, RF energy may affect some
malfunctioning or improperly shielded electronic equipment.
2.7 Vehicle electronic equipment
Check your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
2.8 Medical electronic equipment
Consult the manufacturer of any personal medical devices (such as
pacemakers, hearing aids, etc.) to determine if they are adequately
shielded from external RF energy.
Turn your STEPPIII 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.

Page 11
STEPPIII Hardware description
Version 1.0.0
2.9 Aircraft
Turn your STEPPIII 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.
2.10 Children
Do not allow children to play with your STEPPIII 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.
2.11 Blasting areas
To avoid interfering with blasting operations, turn your unit OFF when in a
“blasting area” or in areas posted: „turn off two-way radio“. Construction
crew often use remote control RF devices to set off explosives.
2.12 Potentially explosive atmospheres
Turn your STEPPIII device OFF when in any area with a potentially explosive
atmosphere. It is rare, but your modem or its accessories could generate
sparks. Sparks in such areas could cause an explosion or fire resulting in
bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always,
clearly marked. They include fuelling areas such as petrol stations; below
decks on boats; fuel or chemical transfer or storage facilities; and areas
where the air contains chemicals or particles, such as grain, dust or metal
powders.
Do not transport or store flammable gas, liquid or explosives, in the
compartment of your vehicle, which contains your modem or accessories.
Before using your modem in a vehicle powered by liquefied petroleum gas
(such as propane or butane) ensure that the vehicle complies with the
relevant fire and safety regulations of the country in which the vehicle is to
be used.
2.13 Non-ionizing radiation
As with other mobile radio transmitting equipment users are advised that for
satisfactory operation and for the safety of personnel, it is recommended
that no part of the human body is allowed to come too close to the antenna
during operation of the equipment.

5 STEPPIII APPLICATION INTERFACE
5.1 Power supply
The power supply for the STEPPIII terminal has to be a single voltage source of
VVC+ = +10.8 V...+32.0 VDC. It must be able to provide sufficient current which
typically rises to 1.6 A. The operating voltage (VVC+ and GND) is protected
from reverse pole connection.
5.1.1 Power supply pins (15 and 16) on the MOLEX 16-pin connector
One VC+ pin on the MOLEX 16-pin connector is dedicated to connect the
supply voltage, 4 GND pins are recommended for grounding.
The VC+ and GND pins serve for charging the internal Li-Polymer battery and
powering the STEPPIII device. STEPPIII has automatic power ON-function
when external power is applied. The power supply for the STEPPIII is capable
of utilizing current ranging from VVC+ = +10.8 V ... +31.0 VDC designed for
automotive application.

Grounds)
5.1.2 Automatic shutdown
Automatic shutdown takes effect if:
• the STEPPIII board is exceeding the critical limits of over or under
temperature.
• the battery is exceeding the critical limits of over or under
temperature.
• under voltage is detected.
The automatic shutdown procedure is equivalent to the power-down
initiated, i.e. STEPPIII logs off from the network and the software enters a
secure state avoiding loss of data.
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.
The FALCOM STEPPIII is designed for use as a DCE. Based on the
aforementioned conventions for DCE-DTE connections it communicates with
the customer application (DTE) using the following signals:

6.1.2 Special pin description
6.1.2.1 Analog inputs (2, 4, 6, 8)
Analog voltages up to 32 V with 10 bit resolution can be processed and
remotely evaluated by a server application. Pull-up resistor to a constant
input voltage allows for resistive transducers to ground, e.g. fuel sensor or
thermistors. Because the pins 2, 4, 6, and 8 can operate either as digital or
analog, they have to be configured and calibrated for such purposes
before using as analog outputs.
↓ Connection example for analog input 0 (IN0):
Thus, an analog input can be connected to a temperature sensor (a NTC
resistor for instance). It is possible to set a low temperature alarm and a high
temperature alarm (upper and lower values), passed to required
temperature. Passage through these thresholds will trigger an alarm. We
recommend to use SMS or TCP as alarm type with GPIOP as attachment
protocol. The SMS can be received on a mobile phone, modem or any GSM
device. An application example is shown in figure below:
Figure 5:
Connection example for analog input (IN0)
↓ Connection example for analog input 1 (IN1):
Likewise, on another analog input you can install a tachometer generator.
The maximum output voltage of the tachometer is + 32 V (see illustrated
example in figure below).
Both circuit examples (the NTC diagram above and the Tachometer) are only illustrations to
show the aim of the analog inputs.

6.1.2.2 Digital Inputs (pin 10,12)
The inputs (pin 10, 12) on the MOLEX 16-pin connector are high active so
they can be connected to + 5 V ... 32 V DC. The figure below illustrates how
to connect these inputs. If one of the connected pins (inputs) is activated
(for at least 1 sec), STEPPIII will release an alarm (SMS or data connection).
The alarm type and the alarm text (alarm type SMS) depend on the software
configuration done by the user. The inputs can be configured by using the
Command Set manual. All inputs reserved for customer specific applications
can be connected as shown below:

6.1.2.3 Outputs (pin 5, 7, 9, 11)
The STEPPIII supports four outputs. These can be set remotely by the server
application. The figures below show the schematic of possible output
connections. Each output can be directly connected to a LED, Relay etc.,
which needs no more than 100 mA. The figures below show the schematic of
possible output connections.

6.1.2.4 Ignition (pin 13)
STEPPIII provides two Ignition pins, one on the Molex connector (pin 13) and
one on the AMP connector (pin 13). Their functionality is the same. The
vehicle ignition line (starter lock clamp 15) can be connected to one of the
IGN pins of terminals (Pin 13). Thus, it is possible to send an alarm SMS (by
starting the car engine), prerequisite, the input IGN of the STEPPIII should be
configured for this purpose. Both pins 13 on the Molex connector and AMP
connector are internally connected with each other, so they can be
alternatively used. For more information see the corresponding figure in
chapter 10.1.1.
Note that, the IGN pins on the STEPPIII are not assumed to switch on the
STEPPIII terminal, they are only input pins, which can be used to control, for
example, the vehicle Ignition key.

Page 27
STEPPIII Hardware description
Version 1.0.0
The SIM interface controls an internal small 3 V SIM card. This interface is fully
compliant with GSM 11.11 recommendations concerning SIM functions.
Note: The SIM should not be removed, while the module is powered
on. The SIM must only be removed when the STEPPIII is shut
down. To remove the SIM card press the Eject button (see
figure 11) then pull out the SIM card holder.
Note: The unit is not designed for use of single 5 V SIM cards. These
cards will generate an error which cannot be distinguished
from a faulty SIM card.
6.3 Interfaces C and D
The STEPPIII is fitted with two male SMB FAKRA connectors that accept a wide
variety of GSM/GPS antenna styles. One of them (right) (see figure below), is
provided for GSM RF connection. The GSM RF connector has an impedance
of 50 Ohm. A GSM antenna can be directly connected to this connector.
The other left-one is provided for GPS RF connection. The GPS RF connector
(see figure below) has an impedance of 50 Ohm. Active antennas have an
integrated low-noise amplifier. They can be directly connected to this
connector. The integrated low-noise amplifier of the antenna is internally
supplied with the specified voltage.
FALCOM GmbH provides a combined GSM/GPS antenna, especially, for the
STEPP devices, the GSM antenna operates on four frequencies: GSM 850/900
MHz and DCS 1800/1900 MHz. The GPS antenna operates on 1575.42 MHz
frequency. This antenna is suitable for mounting, covertly if required, in
various locations.
The order name of combined GSM/GPS antenna is: FAL-ANT-5
In order to operate properly the GPS part, it is recommended the GPS active
antenna should not exceed 25 mA. The antenna voltage is supplied
internally. The GPS antenna is protected from reverse pole connection.
The figure below shows the position of GSM/GPS connectors.

10.1 Schematics
The figures below illustrate the recommended schematics for the connection
of the Molex and AMP connectors. For detailed information, please, refer to
the related documents [1.4].
10.1.1 Installation guidance for 16-pin Molex connector
On the top of the schematic the corresponding pin out of the 16-pin Molex
connector can be found.
A general purpose terminal providing multiple digital and analogue inputs as
well as outputs for a variety of uses.
The STEPPIII comprises 5 inputs, 4 outputs and 4 analog or digital inputs
(software configuration dependent).
Of the 5 inputs, 2 inputs are free available for the user application. Three of
the inputs are predefined by the factory as follow:
● 1 x Power supply : Connect to the vehicle battery (clamp 30).
● 2 x Ignition lines : Connect to the vehicle starter lock (clamp 15)
and use it for triggering alarms whenever the
vehicle ignition key is closed (engine started).
4 digital inputs can be used to trigger any alarm type (SMS or data), i.e. they
can be connected to the car alarms or to a door switch, etc.
4 digital outputs allow remote control of external actuators. A schematic
below in this section shows how digital inputs/outputs can be used.
Note that, the outputs of the STEPPIII and VC+ must connected on the
same voltage level as the supply voltage VC+ operates.
STEPPIII device is not protected against over-voltage and over-current.
The operating voltage range must never be exceeded. The positive
wire of the STEPPIII (input power supply) must always be protected
manually with a 2A fuse at +10.8 … +32 VDC. See circuit diagram
below
Please note that, all ground pins of the STEPPIII unit should be isolated
from the vehicle body to avoid ground loops.
CAUTION
IF YOU USE A GROUND-MOUNTED ANTENNA, TO AVOID ANY FAULT
CURRENT ENSURE THAT ANTENNA GROUND DOES NOT COME INTO
CONTACT WITH VEHICLE BODY. PLEASE, DOUBLE-CHECK ALL GROUNDS
AND OTHER USED LINES WHETHER THEY ARE ISOLATED FROM VEHICLE
GROUND.
