GETTING STARTED WITH COMPACTRIO – PERFORMING BASIC CONTROL
The National Instruments Compact An advanced embedded data and control acquisition system created for applications that require high performance and reliability equals RIO programmable automation controller. The system has open, embedded architecture, extreme ruggedness, small size, and flexibility, that engineers and embedded planners can use with COTS hardware to instantly build systems that are custom […]
I²C (INTER-INTEGRATED CIRCUIT)
I²C (Inter-Integrated Circuit), pronounced I-squared-C or I-two-C, is a multi-master, multi-slave, packet-switched, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors). It is typically used for attaching lower-speed peripheral ICs to processors and microcontrollers in short-distance, intra-board communication. Alternatively, I²C is spelled I2C (pronounced I-two-C) or IIC (pronounced I-I-C). Since October 10, 2006, […]
WHAT IS RS422?
RS-422, also known as TIA/EIA-422, is a technical standard originated by the Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit. Differential signaling can transmit data at rates as high as 10 Mbit/s, or may be sent on cables as long as 1500 meters. Some systems directly interconnect using RS-422 signals, or […]
APPLICATIONS OF RS-485
RS-485 signals are used in a wide range of computer and automation systems. In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. RS-485 is used for low-speed data communications in commercial aircraft cabins’ vehicle bus. It requires minimal […]
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 […]
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 […]
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, […]
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 […]
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 […]
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 […]
