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, […]
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 […]
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 […]
COMMUNICATION INTERFACES
When considering piezoelectric precious stone gadgets for use in a DAQ system, a great many people consider vibration and accelerometer sensors as these gems are the reason for the universal ICP/IEPE sensors. It is, for the most part, comprehended that when you apply a compel on a piezoelectric precious stone it makes the gem misshape […]
OTHER TYPES OF DAQ HARDWARE – PART 3
Output Drive Make certain to research how much momentum is required by whatever gadget you are endeavoring to drive with the analog yield channel. Most D/A channels are restricted to under ±5 mA or ±10 mA max. A few merchants offer higher yield streams in standard yield modules (e.g., UEI’s DNA-AO-308-350 which will drive ±50 […]
OTHER TYPES OF DAQ HARDWARE – PART 2
Monotonicity In spite of the fact that it’s sound judgment to accept that on the off chance that you charge your yield to go to a higher voltage, it will, paying little respect to the general precision. In any case, this is not really the situation. D/A converters show an error called differential non-linearity (DNL). […]
“OTHER” TYPES OF DAQ I/O HARDWARE – PART 1
This article portrays the “other normal” sorts of DAQ I/O — gadgets, for example, Analog Outputs, Digital Inputs, Digital Inputs, Counter/Timers, and Special DAQ capacities, which covers such gadgets as Motion I/O, Synchro/Resolvers, LVDT/RVDTs, String Pots, Quadrature Encoders, and ICP/IEPE Piezoelectric Crystal Controllers. It likewise covers such themes as interchanges interfaces, timing, and synchronization capacities. Analog Outputs Analog […]
COMMON MODE AND CMRR
The distinction between the “normal voltage” of the two differential inputs and the input ground is alluded to as the signal’s Common Mode. Scientifically, the Common Mode voltage is characterized as Where Vhi is the voltage of the signal associated with the V+ (or VHi) terminal and Vlow is the voltage on the V-(or Vlow) […]
