x4 Gen1 PCI Express Host, 838 MB/s, Fiber-Optic Cable MXI-Express Device for PXI Remote Control—The PCIe‑8375 is an MXI‑Express remote controller for devices or systems cabled over PCI from a computer with a PCI Express slot. The PCIe‑8375 remote controller provides a x4 PCI Express link over a fiber-optic cable to the PXIe‑8375 remote control module when used for PXI system control. Fiber-optic remote control solutions are ideal for long‑distance‑device control and electrical isolation. This link is transparent to software applications and drivers, so industry‐standard desktop computers and servers can control connected devices with no additional programming. With NI remote controllers, PXI modules can be used as if they are PCI devices directly installed in the computer.
