Figure 1. NI MXI Express uses cabled PCI Express to connect a PC to PXI
The x1 MXI Express form factor shown above uses a PCI Express slot in a desktop PC to connect to a PXI chassis. The
ExpressCard form factor shown below supports a x1 cabled PCI Express link to a PXI chassis using the same cables.
Thus the PXI module and cables are common to both laptops and desktops allowing for higher reuse.
