MXI-Express Gen II x8 Series User Manual
Note
In this manual, whenever a PXI Express chassis is referenced, a CompactPCI
Express chassis could be used instead.
Larger MXI-Express Gen II x8 Systems
If multiple PCI Express slots are available in the host PC, additional PXI
Express chassis can be connected by installing an additional NI PCIe-8381 in
any available Gen II x8 or wider PCI Express slot.
You can also daisy-chain from a PXI Express chassis that is already
controlled by an embedded controller, host PC, or laptop to additional
PXI Express chassis using MXI-Express Gen II x8 products. Figure 1-6
shows how you can use MXI-Express Gen II x8 cards to connect multiple
PXI Express expansion chassis to a PC in a star or daisy-chain topology.
