Chapter1 Introduction
1.1 Overview
The MOXA RS-232 to RS-422/RS-485 bidirectional converters,
A50 and A51, are designed to convert unbalanced (single-ended)
RS-232 signals to balanced (differential) RS-422/RS-485
signals, and vice versa. They are the best choices for those who
want to control devices at longer distance and/or to
communicate with several devices via merely one link,
particularly in the industry area. Point-to-point, multidrop and
simplex operations are available for most users' needs.
