Starter-kit including evaluation
and configuration tool
is a Plug & Play GSM/GPRS/GPS terminal with an
embedded configurable software application.
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 4 digital and 2 analogue inputs
as hardware back-bone. In addition to that two
predefined digital inputs are detecting ignition line
and main power (car battery) failure.
Depending on the specific system solution scenario four digital outputs allow the remote control
of external actuators. The integrated two audio
channels allow voice communication too.
The STEPP II concept reduces the efforts for the creation of a turn key tracking and security solution
to the definition of the server (dispatcher) application. In this way the time-to-market, the design-in
risk and the total cost of solution are substantially
The STEPP II-STARTERKIT provides an easy and efficient way to evaluate and configure all system
parameters of the mobile client. The configuration
of the STEPP can be done via local serial link or remotely via the GSM network.
