Techiess,
Thank you for contacting National Instruments.
Do you have the current DAQmx driver installed on your computer? If you don't or are unsure, you are able to download the latest
DAQmx driver. Please look through the
DAQ Getting Started Guide, which walks through the installation of the PXI device. Also step through the
Configuring Your PXI System in MAX 3.x and Above, which steps through the configuration of the PXI System in Measurement & Automation. The previously referenced link
MXI-3 and MXI-4 Troubleshooting Guide, is another great reference to walk through troubleshooting your MXI-4.
If none of these suggestions solve the issue, please send me a screen shot of the Device Manager, with the appropriate device fields expanded, and Measurement & Automation with the device fields expanded.
Thank you very much.
