SERIAL COMMUNICATIONS – RS-485

RS-485, also known as TIA-485(-A), EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported. The standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected

3 STEPS TO UNDERSTAND RS232 DEVICES

Having troubles with controlling your RS232 device? This article will certainly help you understand almost all of the hardware and software standards for RS232.  Step 1: Understand RS232 Connection & Signals RS-232C, EIA RS-232, or simply RS-232, refers to the same standard defined by the Electronic Industries Association in 1969 for serial communication.DTE stands for Data Terminal Equipment. Any computer is a DTE. DCE stands for Data Communication Equipment. Any

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) MSBThe above

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

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. Be

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.) At a first glance, Synchros and

SIMPLE WIRING OF CLOCK AND TRIGGER

One last part of “non-standard” information obtaining and control frameworks is the manner by which bigger frameworks are synchronized. Regularly, it is important that you know “what” happened, as well as “when” it happened. In little frameworks, this is normally simple to fulfill as the simple sources of info and even the yield excitation, are on a similar board. Be that as it may, frameworks with high channel include and,

DO YOU KNOW ABOUT RS-232/422/423/485?

Individuals initially started anticipating the downfall of RS-232 in the 1980s. Obviously, RS-232 is still around and kicking. On the off chance that Mark Twain was as yet alive, I’m certain he’d compose something on the request of “The reports of the demise of RS-232 have been enormously overstated”. The RS-arrangement ports remain to a great degree basic in the information procurement and control field.  RS-232 is more established and

MILITARY’S EQUIVALENT TO ARINC-429

MIL-STD-1553 is the military’s equivalent to ARINC-429, though structurally it is VERY different. The first and most obvious difference is that most 1553 links are designed with dual, redundant channels. Though commercial aircraft don’t typically get wires cut by bullets or flak, military aircraft are typically designed such that a single cut wire or wiring harness won’t cause a loss of system control. If you are looking to “hook” to an

DO YOU KNOW ABOUT ARINC-429?

ARINC-429 is the aeronautics interface utilized by all business air ship (however 429 is not the essential interface on the Boeing 777 and 787 and the Airbus A-380). It is utilized for everything from conveying between different complex frameworks, for example, flight executives and autopilots and in addition to observing more short-sighted gadgets, for example, velocity sensors or fold position pointers.  In test frameworks, it’s frequently basic to organize information
