1 INTRODUCTION
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 STEPPII-55/56-LT from
FALCOM GmbH. It contains information about purpose and use of the STEPPII-55/56-
LT concept.
In order quickly to start and immediately and comprehensive to use all functions and
to avoid any mistakes of STEPPII-55/56-LT terminal on your utilization we recommend
to read the following references and suggestions for using your new STEPPII-55/56-LT
terminal.
The STEPPII-55/56-LT is a Plug-and-Play device which provides powerful state-of-the
art technologies (GSM GPS internet) and makes them available for quick and easy
integration into a number of applications for the vertical and horizontal market. The
new STEPPII-55/56-LT concept is a Full Type Approved combined GSM/GPRS/GPS
Smart Terminal.
The compact design of the GSM/GPRS/GSM STEPPII-55/56-LT terminal integrates it in
an all-in-one solution. This combination concept and internally embedded software
(known as firmware) make it available to be used in a wild range of tracking
solutions such as fleet management vehicle tracking navigation emergency
calling location-based services and many others.
The STEPPII-55/56-LT is designed for use on any GSM850 GSM1800 and GSM1900
network. This single compact device is Tri-band GSM/GPRS engine that works on the
three frequencies GSM 850MHz GSM 1800 MHz and GSM 1900 MHz it supports also
state-of-art GPS technology for satellite navigation.
The embedded firmware based on the eCos operating system for the TCP/IP
communication protocol (TCP/IP stack) converts data streams into data packets
and makes GPRS traffic possible for industrial and automotive applications. No PDA
or laptop is needed for establishing a GPRS connection. It has its own TCP/IP and PPP
stack and will work as a stand-alone terminal. STEPPII-55/56-LT features GPRS Multislot
class 10 and supports the GPRS coding schemes CS-1 CS-2 CS-3 and CS-4. The
STEPPII-55/56-LT terminal can send and receive data by GSM and GPRS networks. It
supports SMS data and voice calls as well as Internet and e-mail. The STEPPII-55/56-LT
terminal can be easily controlled by using SMS and PRSF commands provided on the
embedded software for all kinds of operations.
The internal advanced GPS system uses twelve parallel channels providing highly
accurate positional speed time and date information. Using satellite signals the
embedded GPS module enables users to determine the position of device
anywhere in the world. The STEPPII-55/56-LT module has an integrated TCXO that also
improves the GPS system performance. Due to the temperature stabilizing its position
is determined more precisely.
A compact “stacked FLASH/SRAM” device stores the STEPPII-55/56-LT software in the
FLASH memory section of terminal and a static RAM section provides the additional
storage capacity required by GPRS connectivity.
The physical interfaces to the terminal application are made through integrated
connectors. These are required for controlling the unit receiving GPS location data
transferring data and audio signals and providing power supply lines. STEPPII-55/56-LT

provides a serial interface (2-wire and GND on the 16-pin AMP connector) giving you
maximum flexibility for local use.
The internal backup Battery (LiIon- 850 mA/h) is available in case of external Power
failure.

2 SECURITY
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM READ
THIS INFORMATION BEFORE USE!
Your cellular engine STEPPII-55/56-LT 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
STEPPII-55/56-LT. Please read this chapter carefully before starting to use the cellular
engine STEPPII-55/56-LT.
2.1 General information
Your STEPPII-55/56-LT 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 Ex osure 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.
2.3 Efficient modem o eration
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.
