Abstract
A multipoint communications system for transmitting the values of a multiplicity of analog parameters from one point digitally to another point and reconverting then into analog parameters. The system includes a plurality of input modules which communicate with respective output modules over a communications link. The input and output modules are configured similarly with a control processor connected to either multiplexing circuitry, in the case of an input module, or demultiplexing circuitry in the case of an output module. The multiplexing circuitry is connected to a plurality of configurable input circuits which receive the values of the various measured conditions or parameters. The demultiplexing circuitry is connected to a plurality of configurable output circuits which output the values of the various measured conditions or parameters. In a preferred protocol, a link master is chosen from among the input modules to generate a polling sequence for the input-output module pairs.
