Overview

With NI MXI-Express for PXI Express interface kits, PC users with PCI Express

slots can exercise direct control of PXI Express systems using cabled PCI Express

technology. NI MXI-Express 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.

PCI Express Control of PXI Express

With a MXI-Express for PXI Express link, you can transparently control a

PXI Express system from any PCI Express slot, so you can use desktop computers,

servers, and workstations to control PXI Express systems. MXI-Express for

PXI Express features a transparent link where all PXI and PXI Express modules

appear as PCI boards within the computer itself. However, you benefit from the

increased number of slots, power and cooling per slot, module selection, and

synchronization features provided by PXI. The MXI-Express for PXI Express link

consists of an NI PCIe-8361 or PCIe-8362 board in the PC that is connected via

a MXI-Express cable to an NI PXIe-8360 module in slot 1 of a PXI Express

chassis. The NI PCIe-8361 board provides one PCI Express link, which you can

cable to an NI PXIe-8360 module in a PXI Express chassis. The NI PCIe-8362

board provides two PCI Express links, each of which you can cable to individual

NI PXIe-8360 modules in separate PXI Express chassis. Thus, you can use a

single NI PCIe-8362 board and two NI PXIe-8360 modules to simultaneously

control two PXI Express systems. For your convenience, you can purchase either

a complete MXI-Express for PXI Express kit with all necessary components or the

PCI Express board, PXI Express module, and cable separately.

Cabled PCI Express Technology

The NI PCIe-8361 and PCIe-8362 boards provide one or two cabled PCI Express

links, respectively. The links have x1 (“by one”) lane widths. The NI PXIe-8360

module connects 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 the MXI-Express for PXI Express link

with an application written for a PXI system controlled via a PCI or PCI Express

remote controller, such as MXI-3, MXI-4, or MXI-Express.

Multichassis PXI Systems

You can use a single NI PCIe-8362 board to simultaneously control two PXI Express

systems. You also can incorporate multiple NI PCIe-8361 or PCIe-8362 boards

in a PC with multiple PCI Express slots to add PXI Express chassis to a system.

You cannot use an NI PXIe-8360 module to daisy chain multiple PXI Express

chassis. However, using MXI-4, you can connect a PXI Express chassis to a PXI

chassis in a star or daisy-chain configuration within a single system. To connect

a PXI Express chassis to a PXI chassis with MXI-4, install an NI PXI-8331 (copper)

or PXI-8336 (fiber-optic) module in any PXI peripheral slot of the master PXI Express

chassis, and connect it with the appropriate cable to a second PXI-8331 or

PXI-8336 in slot 1 of the slave PXI chassis.
