The ENDECO® DATA-WATCH ADAPTIVE Packet Telemetry System

The ENDECO ADAPTIVE Packet Telemetry System is a hardware and software package for gathering data from up to 99 sites. Each site accommodates eight sensors (and remote control devices). The base station is an IBM-PC which provides real-time data monitoring, printing, and archiving, and which controls all site functions. Inside the IBM is an ENDECO interface card that links the IBM with a radio and a telephone line. The radio is used to start samples and gather data from each site. The telephone is used to call help automatically if an alert arises (e.g. water level too high). The user can also request data or remote control functions by phone or hand radio. Data is spoken using high-fidelity voice synthesis. All sites can also relay radio packets to increase communications range. Packets are rerouted automatically if any site fails.
