RS-232 was originally adopted in 1960 by the Electronic Industries Association (EIA). Over the 40+ years since this standard was developed, the Electronic Industries Association published three modifications, the most recent being the EIA232E standard introduced in 1991. In this document we will see several parts of the original RS-232C standard and mostly the ones used in the PC world. This document will describe the use and configuration of serial ports using RS-232.

Fiber optic communications is widely used in IS Hazardous environments due to the convenience of installation and use. In an IS environment, copper cables carrying a voltage or current potential are often required to be installed into conduit. This ensures safety in a hazardous environment, but also increases installation and maintenance costs.
