1 Security
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM-MODEM, READ THIS INFORMATION BEFORE USE!
Your cellular engine STEPP 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 STEPP. Please read this chapter carefully before starting to use the
cellular engine STEPP.
1.1 General information
Your STEPP device utilises 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 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.
1.2 Exposure to RF energy
There has been some public concern about possible health effects of using
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.
1.3 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.

STEPP
VERSION 1.10
1.4 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.
1.5 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 fulfil road-safety
instructions of the current law!
1.6 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.
1.7 Vehicle electronic equipment
Check Your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
1.8 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 STEPP 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.
1.9 Aircraft
Turn Your STEPP 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.

1.10 Children
Do not allow children to play with Your STEPP 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.
1.11 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.
1.12 Potentially explosive atmospheres
Turn Your STEPP 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.
1.13 Non-ionising 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 be allowed to come too close to the antenna
during operation of the equipment.
The radio equipment shall be connected to the antenna via a non-radiating
50 Ohm coaxial cable.
The antenna shall be mounted in such a position that no part of the human
body will normally rest close to any part of the antenna. It is also
recommended to use the equipment not close to medical devices as for
example hearing aids and pacemakers.

4.1.1.1 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 terms DTE (Data Terminal Equipment) and DCE (Data
Communications Equipment) are typically used to describe serial ports on
devices. Computers (PCs) generally use DTE connectors and
communication devices such as modems and DSU/CSU devices generally
use DCE connectors. As a general rule, DTE ports connect to DCE ports via
straight through pinned cables. In other words, a DTE port never connects
directly to another DTE port. Similarly, a DCE port never connects directly
to another DCE port. The signaling definitions were written from the
perspective of the DTE device; therefore, a Receive Data signal becomes an
input to DTE but an output from DCE.
For cabling, to connect a DTE device to a DCE device, all you need is a
straight through pinned cable.
However, to connect two DTE devices (for example, PC to PC), to transfer
data over their serial ports you need a cross pinned cable to simulate the
missing pair of DCE devices (modems or DSU/CSUs). This cable is usually
called a null modem cable because DCE devices are typically modems.
The Falcom STEPP 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:

7.1.2.1 Analog inputs (pin 2, 4)
Analog voltages up to 32 V with a resolution of 8 bit can be processed and
remotely evaluated by a server application.
↓ Connection example for analog input 2:
Pin 2 (analog input 2) can be connected to a temperature sensor (a NTC
resistor for instance) with restriction values, if the temperature rises/falls,
the STEPP reacts, and sends a message (SMS with voltage values
depending on the user configuration) to the receiving device (mobile phone,
modem or any GSM device), see the illustrated example in the figure below.

7.1.2.5 Ignition (pin 13)
STEPP provides two Ignition Pins (pin 13) on the Molex and AMP
connectors. Their functionality is the same. The Ignition line of the vehicle
(starter lock clamp 15) has to be connected to the Pin 13. Thus it is possible
to send an Alarm SMS (by starting the engine), provide the STEPP has been
configured respectively. Pin 13 of the Molex connector and AMP connector
are connected internally, so that they can be connected alternatively. For
more information see the corresponding figure in chapter “Installation
guidance for 16pin Molex connector”.

The SIM interface controls a internal small 3V 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 STEPP is shut down. To
remove the SIM card press the Eject button (see figure 12) then
pull out the SIM card reader.
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.

10.1 Schematics
The figures below illustrate the recommended schematics for the connection
of the 16 pin Molex and 15 pin AMP connectors.
10.1.1 Installation guidance for 16pin Molex connector
On the top of the schematic the corresponding pin out of the 16-pin Molex
connector can be found.
The STEPP provides 6 inputs, 4 outputs and 2 analog inputs.
Of the 6 inputs, 4 input are free available for the user. Two of the inputs are
pre-assigned at the factory:
-
Power Supply - connect to vehicle battery (clamp 30).
-
Ignition - connect to starter lock (clamp 15).
Ensure that the operating voltage (V+) of the terminal and external power
source (i.e. car battery) incorporates a protection circuit against over current,
which has to be limited to 2 A at +10.8 … +32 VDC. See circuit diagram
below.
A microphone can be connected to pin 1 and pin 3 of the 16-pin Molex
connector.
The figure 18 shows an example for the installation of the STEPP-I/O’s in a
motor vehicle.
