x16 Gen2 PCI Express Host, 3.2 GB/s, Copper Cable MXI-Express Device for PXI Remote Control—The PCIe‑8388 is an MXI‑Express remote controller for PXI Express and CompactPCI Express systems from an NI rack-mount controller. The PCIe‑8388 remote controller provides a x16 PCI Express link over a copper cable to the PXIe‑8388 remote control module for PXI control. This link is transparent to software applications and drivers, so NI rack-mount controllers can control PXI Express systems with no additional programming. With NI remote controllers, PXI modules can be used as if they are PCI devices directly installed in the NI rack-mount controller.
