The National Instruments 781394-01, known as the PCI-8361, is an advanced MXI-Express remote control device tailored for the effective management of PXI systems. This module establishes a seamless PCI interface over copper cabling, allowing PXI modules to connect directly to a host computer without any additional programming requirements. It facilitates data transfer speeds of up to 100 MB/s, making it ideal for applications that necessitate the physical separation of measurement or automation systems from the host PC or laptop. The device can connect to various host computers, including desktop PCs, workstations, and laptops equipped with PCI, PCI Express, or ExpressCard slots, enabling control of PXI, PXI Express, VXI, or CompactRIO chassis.

One of the key advantages of the PCI-8361 is its incorporation of PCI Express technology, which ensures reliable performance and high-speed data communication. It supports a diverse range of backplane configurations, including PXI/PXI Express, CompactPCI/CompactPCI Express, CompactRIO, and VXI, which increases the scalability and versatility of industrial automation systems. The MXI-Express x1 kit simplifies control over PXI or PXI Express chassis from host PCs through the integration of PCI Express switches or PCI Express-to-PCI bridges. This bridge design operates transparently with device drivers, enabling PXI or PXI Express devices within connected chassis to deliver CompactPCI-level functionality without requiring additional software. The 781394-01 ultimately enhances the efficiency and flexibility of industrial automation applications.
