  • 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 busses will the chassis and modules use?

Solution

The total amount of PCI busses varies based on the amount of chassis and cards in the system.
In general, use the table below to get an estimate of how many resources your PXI system requires:
 
PCI Bus Reservations
HardwareBus Requirement
Large Chassis (18 Slot)~25
Compact Chassis (4-9)~10
MXI-Express Host Card (PCI Express)~3
MXI-Express Controller Card (PXI Express)~7
MXI-Express Peripheral Card (PXI Express)~2

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.
