Each NI PCIe-8360 has two MXI-Express connectors. One NI PCIe-8360
may be connected to two different NI PXI-8360 cards in separate
PXI/CompactPCI chassis. If multiple PCI Express slots are available in
the host PC, additional PXI chassis can be connected by installing an
NI PCIe-8360 in any available PCI Express slot.
Figure 1-2 shows how you can use MXI-Express cards to connect multiple
expansion chassis to a PC in a star topology. The star topology is the only
supported topology due to the point-to-point nature of PCI Express.
