Overview
Cabled PCI Express Technology
With National Instruments MXI-Express x4 (“by four”) for PXI Express
interface kits, PC users with x4 or higher PCI Express slots can exercise
The NI PCIe-8371 and NI PCIe-8372 boards provide one and two cabled
PCI Express links, respectively. The links have x4 (a link comprised of four
direct control of PXI Express systems using cabled PCI Express technology. x1 PCI Express lanes) lane widths. The NI PXIe-8370 module connects
NI MXI-Express x4 for PXI Express, a high-bandwidth serial link transparent
to software applications and drivers provides the ability to use high-
performance desktop computers, servers, and workstations to control
PXI Express systems.
these PCI Express links to the PCI Express bus used in the PXI Express
chassis backplane. Thus, all PXI and PXI Express modules appear as PCI
boards within the computer itself.
PCI Software Compatibility
PCI Express features software compatibility with PCI. Without making any
modifications to your software, you can use a MXI-Express x4 for PXI Express
link with an application written for a PXI system controlled via a PCI or
PCI Express Control of PXI Express
With a MXI-Express x4 for PXI Express link, you can transparently control a
PXI Express system from a x4 or higher PCI Express slot, so you can use
desktop computers, servers, and workstations to control PXI Express systems. PCI Express remote controller, such as MXI-3, MXI-4, or MXI-Express.
