The National Instruments PXI-8335 MXI-3 is a fiber-optic interface module that bridges host computers to remote PXI and CompactPCI chassis. Using MXI-3 technology, it establishes a transparent PCI-to-PCI bridge, enabling direct control and access to instruments as if locally installed. The module supports multi-chassis configurations, connecting up to 254 chassis to a single desktop PC, and physically separates measurement systems from host computers while maintaining full hardware and software transparency.

– Compatibility & Integration
The PXI-8335 combines PCI, PXI, and CompactPCI devices within unified systems. LabVIEW and Measurement Studio provide application-level integration. As a transparent PCI-to-PCI bridge, it requires no custom software—host systems recognize remote modules identically to local installations.
