PRODUCTRONICA, Munich – Two system expansion options National Instruments can be used to create multichassis PXI Express systems. The NI PXIe-8364 and NI PXIe-8374 are the first NI PXI Express remote control modules that make it possible to directly interface multiple PXI Express chassis to a single host computer using any expansion topology, without requiring complex custom solutions.
The NI PXIe-8364/74 modules use x1 and x4 MXI-Express links, respectively, to connect downstream and upstream PXI Express chassis, and all PXI modules in the downstream chassis appear as local devices in the upstream chassis. Because MXI-Express links are software transparent, no interconnections require programming, which greatly simplifies multichassis system setup.
The modules use cabled PCI Express as their underlying communication technology, which offers extremely high bandwidth and low latency. The NI PXIe-8364/74 modules provide a maximum data bandwidth of 250 MB/s and 1 GB/s, respectively.
The modules can be used to create systems with multiple PXI Express chassis connected in complex topologies such as star, line or tree.
