Sep 13, 2007  Look at the examples in the Simple Serial library in LabVIEW: C: Program Files National Instruments LabVIEW 7.0 examples instr smplserl.llb LabVIEW Serial.vi. Assuming you are using Windows, go to Start > Programs > Accessories > Communications > HyperTerminal to get a simple application to read and write to a serial port. 147 items - LabVIEW uses the same port to connect to the target RT? I have a dll called 'DLLRTTEST' that I wrote, and claim successfully on my host. The short version is I'm programming a cRIO and apparently the RT. I wanted to use VISA to the serial port of the HyperTerminal on the side-access system in real time.

RS232 communication with a microcontroller using LabVIEW VISA configure serial port Write or read serial port using LabView is achieved with a VISA session. Features are configured to communicate with a 'VISA Serial Port Configuration' to match the microcontroller and computer. The reading is done with 'VISA Read' and a 'Property Node' to read the amount of data received. The writing is done with 'VISA Write' only.

In both cases the session closes with 'VISA Close' and 'Simple Error Handler Hardware In order to connect signals TXD and RXD from a microcontroller to signals RXD and TXD on a PC a conversion between voltage levels is mandatory, and the unit for conversion must also invert the signals. An integrated circuit like MAX232 (Maxim) can be used to convert the voltage levels and invert signals. The chip is placed next to the microcontroller; the principal diagram is given in Fig. Hardware requirements PC computer USB to TTL-RS232 converter cable A pre-programmed microcontroller to read and write to serial port. An integrated circuit like MAX232 Introduction There are many standards describing the connection between a PC and a microcontroller to exchange data (USB, RS232, GPIB.). History of circle kabaddi game history.

The RS232 standard describes wires, connectors, and signals to make a simple and reliable data transfer. The hardware implementing this standard is available in most of contemporary microcontrollers. In order to use the RS232 communication channel the program must first claim its resources by “configuring” the channel. If the requested channel is free to be used then the program can either “write” to or “read” from the opened channel. The program should release the claimed resources before ending, and can do so by “closing” the channel.

This article will explain the following topics in details: 1) 2) 3) After reading this page, you should be able to understand most of the hardware and software (protocol) standards for RS232. If you have a chance to test your RS232 devices with the 232Analyzer software, you should be able to control your RS232 devices in a short period of time. 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 and DCE DTE stands for Data Terminal Equipment. A computer is a DTE.
