A tracking device based on the GSM network for data exchange. It uses GPS to precisely calculate its position, and then sends this data via SMS to a call center. Digital input and output is integrated into the equipment and optocoupled for interface to external devices, along with 2 analog inputs for measurement  and 2 analog outputs for control .All I/Os are controlled by SMS .

APPLICATIONS:

Vehicle tracking  for logistic and security systems , alarm and monitoring applications , or I/O remote control .

OPTIONS:

Complete software for security systems based on PC , with digital Map

FUTURE DEVELOPMENT :

A compiler for LADDER language will soon be avaliable , so the customer can develop the application themselves.

This product is an example of an application of the DDS129, where it is used to create a DMX console which is programmable over distance.

In this application, the firmware generates DMX512 through the RS485 serial port, making it possible to program and monitor the 512 DMX channels via SMS, or by point-to-point connection. For instance, you could switch on/off lights or colours in a lighting system just by a message made from a GSM cell phone or GSM modem .

This application is available in US by 1900Mhz GSM phone on request .

This is an accessory of the DDS129. It is able to display messages from a call center via an LCD screen , input phone numbers through a key pad , unlock security systems by code or store tracking data in a smart media card (16 Mbytes).
