1.3.3 GPS Cellular Module
The LCU500 manufactured by STARCOM is an Add on (off the shelf unit) in the TTMS. It integrates a GPS
receiver, a cellular network modem (GSM/GPRS/EDGE, CDMA/1X). The system monitors various vehicle
sensors, and provides the customer with a vast variety of real-time activities and information about the
vehicle.
The AVL Reader communicates with the LCU500 via RS-232 . From the moment the system is set, the
electronic sensors and AVL Reader begin to routinely communicate with the driver and control center,
reporting any activity involving the hatches, valves as well as the status of the truck, for complete monitoring
and security.
The GPS – Cellular Module (GPRS) performs the following functions:
• Continuously receives clock and location updates via GPS
• Transmits data between the AVL Reader and the Control Center, where data transmitted to
the Control Center is sent with the clock and location information.
