Simple and Robust Multipoint Data Acquisition Bus Built on Top of the Standard RS232 Interface

Abstract

A small-scale wired sensor network architecture built on top of the standard RS232 serial link with the minimum additional non-standard hardware components is described. The presented network structure and associated protocol can be used to form a general purpose distributed data acquisition bus. Basic methods of data flow control and failure recovery suitable for the described architecture are proposed.
