Hardware

  • PXIe-1065
  • PCIe-8381
  • PXIe-8381

Issue Details

My project requires multiple daisy-chained PXI chassis connected via MXI to my host computer. How many PCI buses will the chassis and modules use?

Solution

The total amount of PCI buses varies based on the amount of chassis and cards in the system. Estimates of how many resources your PXI system requires can be found in Mitigating MXI-Express PC Incompatibility. 

Additional Information

You can determine how many the amount of PCI buses your computer has available by referencing Determining the Number and Range of PCI/PCI Express Root Bus Devices.
