Example SynchAI-AO does not work
Hello! I use a USB 6621 and I tried to run the code example, ANSIC C SynchAI-AO delivered with the equipment. First of all, I got the following error message: DAQmx error: terminal Source routing is not found on the device Make sure that the name of
Do not understand RMS voltage
Hello I have to write a measurement software that uses a NOR-DAQ 6071E. C++ is used as programming language and the new DAQmx interface is used and seems very well at the moment. Now, I have a few Questions about the two functions DAQmxCreateAIVoltag
Analog output using DAQmx task
I need a signal to analog waveform using 6259 output, I followed the instructions to "Build an analogue output VI in NOR-DAQmx" in the developer area OR, when I run the code I receive thefollowing error message "Error-50103 occurred in the DAQmx writ
I overload with cDAQ-9172 and the NI 9234
The DAQmx Read property for ' overloaded channels exist "is not supported by my hardware (cDAQ-9172 with NI 9234). What can I use to stop the vi if the tension in the analog input is overloaded?
DAQ + DAC... OR PCI-6143 + PCI-6731 vs only PCI-6229?
Hi, I try to control a XYZ stage using a feedback program in LabVIEW and wonder about my computer card options for the acquisition of analog data (1) analog inputs and 2 digital outputs. One suggestion I've gotten is the NI PCI-6143 of data acquisiti
LabVIEW code for two daq cards
Hi all I'm reading the analog signals using the USB-6210 device and function DAQmx. How to write my code so it would work with the NI USB-6210 or USB-6218 since both a pinout similar devices. Thank you dp128
Find the time to intersampling between two channels AI USB 6251
Hello I want to know how late it is between two-channel sampling of HAVE in a USB-6251 (term mass) used in conjunction with a block of connection SCB - 68 (Labview 8.5, Windows XP). I realize that there's only an ADC and simultaneous acquisition is
With the help of RTD in PCI-6259
Hello I'm trying to measure temperature using a 3 wires RTD and a 6259E PCI data acquisition card. All examples and tutorials that I found were the RTD module or not use regular data acquisition. Is there a way to connect to the RTD in a regular data
Why can't program (USB-6251, Labview8.5)
Hi all My task is: 3 inputs analog 01 analog output 01 or 02 outputs using counter, which put permanently off pulse train. I do not understand why I could not stop my program (can not stop all looped) by pressing the stop"" button. Program stops when
Problem to stop the task of continuous using API C DAQMx data acquisition
I'm doing the acquisition of data in the PCIe-6536 continuously using DAQMx C API. But whenever I try to erase the task and put end to my application, program stops and it is not completed by the Task Manager and task killer applications. Can someone
Error code 200020 after self-test when chassis turns off
Hello This may seem absurd, but I accidentally ran a self-test to the MAX on one of the NI PXI boards (6533) in my chassis (NI 1042 q) when chassis power was off. He returned with an error code of 200020. The same thing has happened with three other
How the ND_SCANCLK_LINE signal used in DAQmx? It is complete Hold event?
I have moved an old application (using the PCI-6013-OR map) to DAQmx recently, but have some difficulty working. When starting, the signals are configured as shown below. Select_Signal (1, ND_PFI_2, ND_IN_CONVERT, ND_HIGH_TO_LOW);Select_Signal (1, ND
Problem with the help of several sensors piezo with DAQ
Hey there, For a drum program, I have 2 buzzers piezo related to data acquisition in the code, I put it in place so that a different sound sample would be assigned to each sensor. However in the beginning, when I run the code, I hit a sensor (a1), he

I have a question about the "scheduled" to complete a call to ibwrite. Here is a code snippet... This code works well but the question I have is regarding the time required to complete the call. Synchronization of data below were collected with a HP
Visa and executable
Hello everyone! I have a problem with the visa and files executable labview. I did a VI that use a serial port visa and who have a control to let the customer choose with serial port on which he wants to work. The program works correctly in Labview.
Can I set up the weather station of parallel port?
Hi guys,. I am designing the weather station via a parallel connection. Is it possible to control signal and receive the result through parallel communication? Because I could find no option for connection in parallel in the entry/exit labview instru
Understand the values fixed point of a NOR-9203
I have a cRIO-9073 with a NI 9203 module. In LabVIEW FPGA, the card values are returned as a fixed point. LabVIEW chosen fixed point properties are (+/-, 21-4) that apparently offers a range of (- 3.125E - 2, 3.125E - 2, 2.98E - 8), and the current c
