INTRODUCTION TO RS232 SERIAL COMMUNICATION - PART 2

Assume we want to send the letter ‘A’ over the serial port. The binary representation of the letter ‘A’ is 01000001. Remembering that bits are transmitted from least significant bit (LSB) to most significant bit (MSB), the bit stream transmitted would be as follows for the line characteristics 8 bits, no parity, 1 stop bit, 9600 baud.
 

LSB (0 1 0 0 0 0 0 1 0 1) MSB
The above represents (Start Bit) (Data Bits) (Stop Bit)

Introduction to RS232 Serial Communication - Part 1

Serial communication is basically the transmission or reception of data one bit at a time. Today’s computers generally address data in bytes or some multiple thereof. A byte contains 8 bits. A bit is basically either a logical 1 or zero. Every character on this page is actually expressed internally as one byte. The serial port is used to convert each byte to a stream of ones and zeroes as well as to convert streams of ones and zeroes to bytes. The serial port contains an electronic chip called Universal Asynchronous Receiver/Transmitter (UART) that actually does the conversion.

Computerized Outputs

Digital Outputs require a similar investigation and large portions of indistinguishable contemplation from advanced data sources. These incorporate watchful thought of yield voltage go, greatest refresh rate, and most extreme drive current required. In any case, the yields likewise have various particular contemplations, as portrayed beneath. Relays have the benefit of high off impedance, low off spillage, low on resistance, irresoluteness amongst AC and DC flags, and implicit segregation.

Synchros and Resolvers

Synchros and Resolvers have been used to measure and control shaft angles in various applications for over 50 years. Though they predate WWII, these units became extremely popular during WWII in fire/gun control applications, as indicators/controllers for aircraft control surfaces and even for synchronizing the sound and video in early motion picture systems. In the past, these units were also called Selsyns (for Self-Synchronous.)
