DAQ Assistant Says No Supported Devices Found Primary Software: LabVIEW Modules>>Real-Time ModulePrimary Software Version: 5.0 Primary Software Fixed Version: N/A Secondary Software: LabWindows/CVI Add-ons>>Real-Time Module Hardware: Multifunction DAQ (MIO)
Problem: When I use the DAQ Assistant to generate basic DAQmx code, it shows a message saying "No Supported Devices Found" and will not allow me to proceed. How do I fix this? Solution: This message indicates that for some reason National Instruments does not detect any DAQmx devices installed on your local machine. Follow these troubleshooting steps to try and fix this: 1. Ensure that a DAQmx device is installed on your system. If you are developing code that will execute on another computer and the hardware is not present on the local machine, you might get this message because the hardware is not present. This is very common when using LabVIEW or LabWindows/CVI Real-Time module since the hardware is typically installed on a remote machine. In order to proceed with the DAQ Assistant, you either need to install the hardware locally or try using a simulated device. The DAQmx driver introduced Simulated Devices. This functionality allows you to simulate the basic functionality of a multifunction data acquisition device without actually having it installed on your local system. For detailed information about simulated devices, please visit NI-DAQmx Simulated Devices. Since Simulated Devices are configured on the local system as if hardware were present, you will no longer encounter this message. Ensure that the simulated device names are the same as the actual hardware on the target computer (as configured in Measurement and Automation Explorer. Note that not all DAQ devices can be simulated. If your device cannot be simulated, it is recommended that you choose a device most similar to the actual device you are using. 2. Check if the device shows up properly in Measurement and Automation Explorer. National Instruments provides a tool called Measurement and Automation Explorer (MAX) that provides configuration for National Instruments products (and some IVI devices) on your system. You can launch MAX from Start»Programs»National Instruments»Measurement and Automation. Click the plus sign (+) next to Devices and Interfaces. Then click the plus sign (+) next to NI-DAQmx Devices. Here you can find all of the DAQmx devices installed on your local machine (simulated and non-simulated). If this category is not displayed, either the DAQmx driver is not installed on the system or no DAQmx devices are recognized on your system. Ensure that your device is compatible with the DAQmx driver by visiting Data Acquisition (DAQ) Installation/Configuration Troubleshooter. If a device shows up with a white icon with a red X, it is currently not found in your system. If either a device does not show up in this list or it has a red X to the left of it, proceed to step 3. If it does show up in this list and has either a yellow or a green picture of a DAQ card to the left of it, right-click on the device and select "Self-Test". If this passes successfully, right-click on the device and select "Test Panels". Ensure that the device is able to perform basic functionality (Analog Input, Analog Output, Digital Operations, etc). To test your device for most operations, please run the DAQ Diagnostic Utility. If these steps are unsuccessful, please contact support. 3. Check if the device shows up in the Device Manager of Windows. Most hardware that directly connects to the computer (excluding any accessories such as SCXI accessories, SCXI modules, etc.) should show up in Windows Device Manager. To access this list, right-click on the My Computer icon and select Properties. Then select the Hardware tab and then Device Manager. Most DAQ devices will be listed under a category called Data Acquisition Devices. If either this category or a specific DAQ device is not listed in the Device Manager, the device is not recognized on your computer. If the device shows up with question mark or an exclamation point, the device driver is having trouble initializing. This could occur for various reasons. Try the following steps if either of these conditions occurs. First of all, ensure that the DAQmx driver is installed. For PCI DAQ cards, try changing to a different PCI slot. For USB DAQ devices, ensure that the device uses the USB ports on the back of the computer. If using a laptop, sometimes the USB ports do not provide enough power. These are just some basic troubleshooting steps for device recognition. For more recommendations, please refer to the articles below or contact support.
