NI PXI-8336 MXI-4 Interface Module

The NI PXI-8336 MXI-4 Interface Module is a fiber-optic bridge solution enabling remote control of PXI systems from a host computer. Using MXI-4 technology, it implements a PCI-to-PCI bridge architecture split into two halves and connected by a 1.5 GB/s serial link, delivering software and hardware transparency. The module integrates PXI and CompactPCI devices into unified systems that operate as direct PCI extensions of the host computer. Its fiber-optic design provides electrical isolation and supports cable runs up to 200 m—ideal for distributed test environments requiring spatial separation between control and instrumentation hardware.
