Abstract
A modular bus system for reporting the status of a plurality of geographically distributed data points. The data points may be independently located or grouped with the status of each being monitored by a processor which is coupled to the data points via a bus multiplexer, a plurality of buses and a plurality of single point and multiplexed transmitters. Each bus may be coupled to a plurality of the transmitters and may be configured open or closed loop. The system operates to simultaneously interrogate each of the buses via interrogation signals, which also supply the power to the transmitters, and produces a serial response signal containing the status information of the interrogated data points.
