My NI USB device will occasionally lose connection to the computer, and I have to disconnect and then reconnect it before it will work. Why does this happen, and how can I get Windows to re-detect the ...

I want to know the error associated with the "Non-Linearity" of my DAQ device. What are the INL and DNL errors in the specifications of my DAQ device?

While reading the specifications of my DAQ device, I found a terminology called Absolute Accuracy at Full Scale. What is the meaning of Absolute Accuracy at Full Scale and how can I calculate it?

My NI USB devices are showing up with RAW in their name in Measurement & Automation Explorer (MAX) on my Windows machine. Additionally, I cannot communicate with them using Test-Panels or reset the device. ...

I want more precision on my DAQ device. Can I use a smaller voltage range to get more precision with my analog input?

I am deploying an application that uses a USB DAQ device and everything works fine. However, every time I connect the USB DAQ device, the NI Device Monitor popup window shows up with a Device Detected ...

When using a DAQ device to acquire voltage data, the displayed voltage amplitude is lower than expected.

The PXI(e) card in my chassis will not perform a Self-Calibration in NI MAX. I'm getting the following error message: Status Code: -201295 Device could not complete the calibration operation. Calibration ...

I have two I/O devices of the same type (i.e. two sinking or two sourcing ones). I want to connect them together. Is that possible? Does my sinking output device require an external voltage source?

I have created a DAQmx Task that references multiple devices. I keep seeing error -89137. How can I fix this? I am programming multiple tasks or connecting multiple terminal routes in an NI-DAQmx device.However ...

I am using the Pulse Measurement Counter Input tasks in DAQmx with my DAQ device and I am getting the following error at DAQmx Create Channel VI: Error -200431 occurred at DAQmx Create Channel (CI-Pulse ...

I have old DAQ hardware or hardware that uses DAQmx that I am not sure is supported in my version of LabVIEW. How do I determine if my version of LabVIEW or DAQmx is compatible with my hardware and operating ...

I would like to control a PXI/SCXI Combination Chassis with a PXI M Series device. Which device can be used and what do I need to pay attention to?

I have an NI PCIe (PCI Express) card and I want to know how many bus lanes it uses. In my Development PC, I have a few PCIe slots: x1, x4, x8, x16. Some of them are taken. How can I check if my card is ...

I have one or more channels on my DAQ device not connected to any signal or sensor or the device is disconnected from the computer. Why are all of thechannels reading the same value? Why are my channels/signals ...

I am using some Digital Input (DI) lines on aNI-USB 621x device. How should the ground pins be connected? Can I connect a Digital Ground (D GND) pinon a NI USB-621x to an external ground reference? What ...

You depend on measurements to make key decisions and discoveries. NI offers a wide range of data acquisition products, including the low-cost DAQ family for basic applications such as simple data logging, ...

This document is part of the Getting Started with NI-DAQmx Series. A Pulse Width Modulation (PWM) Signal is a technique for generating digital pulses to control an analog circuit. A PWM signal consists ...

I have multiple NI data acquisition (DAQ) devices. When I acquire data (DAQmx Read (VI) multiple channels) and then merge them in to one TDMS file by usingTDMS Write Function, the resulting file volume ...

I am scanning multiple channels using a multifunction DAQ device, but I am seeing the trends of one channel being reflected in the subsequent channel. However, when I only measure from a single channel ...

I want to control a stepper motor drive (step/direction) using the digital output on my USB DAQ and I have connected all the necessary wiring, so how do I control the motor for some simple moves in LabVIEW? ...

I have a data acquisition device that I would like to use on my Linux machine.Where can I find a list of DAQ hardware modules and devices supported by or compatible with NI-DAQmx Base?

I have a NI Multifunction I/O module with some Analog Output (AO) lines. I need to control an instrument using current. What is the current range the AO lines on my card?

I have a PCIe card, and it shows up in NI MAX and in Windows Device Manager, but it doesn't show up in NI Device Monitor. I have a USB RIO, and it shows up in NI MAX, but it doesn't show up in NI Device ...

When I am using NI-DAQmx with support for LabVIEW, is the Raw Data from the DAQmx Read.vi calibrated? How can I convert the acquired binary values to scaled values?

Why do I receive Error -200558 whenI try to use a task that contains multiple DAQ devices? One task cannot contain multiple independent devices. Create one task for each independent device.
