Multiplex Communication System
SYSTEM DESCRIPTION
1. MULTIPLEX COMMUNICATION SYSTEM BASICS
a. The SEQUOIA multiplex communication system uses serial communication, which converts multiple pieces of information into serial
communication data. As a result, they can be transmitted through a single communication wire.
b. Serial communication data consists of bits and frames. A bit is the basic unit that represents the amount of information. A bit is represented by
a binary value "0" or "1". A frame is a body of data that is transmitted together. A frame contains a "header" that indicates the beginning of the
data and an "end message" that indicates the end of the data.
