The NI PCIe-8381 is an MXI-Express Gen II x8 remote controller module that establishes high-bandwidth communication between a host PC and PXI Express or CompactPCI Express chassis. Operating as a transparent link to software and drivers, it enables industry-standard computers to control remote PXI modules without requiring additional programming. The module connects via PCI Express Gen II x8 slot to a PXIe-8381 or PXIe-8380 remote control module using copper or fiber-optic cable, delivering up to 3.2 GB/s unidirectional throughput. This architecture supports multiple chassis control from a single host PC, providing physical separation between the measurement system and the host computer.
