National Instruments provides several chassis expansion MXI products you can use to create multichassis PXI systems that interface to the same system computer. The system computer in the master PXI chassis can be either an NI embedded controller or a PC connected via an NI remote controller.
Because MXI links are software transparent, they do not require any programming. All PXI modules in the slave/downstream chassis appear as local devices in the master chassis. Because the underlying communication technology for most National Instruments remote controllers is cabled PCI Express, these controllers offer extremely high bandwidth and low latency. These features simplify the process of expanding PXI systems to include multiple chassis while offering high performance.
