National Instruments 778957-01 MXI-4 Interface Module 

National Instruments part number 778957-01 is an identifying part number for the PXI-8336, an MXI-4 Interface Module with fiber optic cable wire of 200 m. This device can be linked with either the PCI-8336 or another PXI-8336 card. As part of the MXI-4 Series, this card is designed to connect two distinct bus systems. The connection is established via a data link that supports data transfer speeds of up to 1.5 GB/s. When using a 778957-01 with a PCI-8336, users can manage a CompactPCI/PXI backplane from a PCI-based computer. Additionally this device operates on a single slot. The 778957-01 is designed to automatically detect whether it is installed in a controller or non-controller slot and adjust its configuration accordingly. 

By using multiple MXI-4 pairs, users can create extensive PXI/CompactPCI/PCI systems. The MXI-4 hardware fully supports PCI standards, allowing for the simultaneous operation of up to 255 bus segments within a single PCI hierarchy. Moreover, the 778957-01, along with other MXI-4 Series cards, can provide additional PXI or CompactPCI slots for user applications. This solution enables a rapid separation between automation or measurement systems and the host PC. 

The MXI-4 system supplies the necessary resources to integrate CompactPCI, PCI, and PXI devices within a single system. The 778957-01 card can be configured in two primary ways: it can be installed in either the controller slot or a non-controller slot of a compatible PXI/CompactPCI chassis. MXI-4 allows for the connection of multiple PXI chassis in either a star or daisy-chain configuration within a single system. To link two PXI chassis using MXI-4, insert a PXI-8331 (copper) or PXI-8336 (fiber-optic) module into any peripheral slot of the master chassis. Then, use the corresponding cable to connect to a second PXI-8331 or PXI-8336 module installed in slot 1 of the slave chassis.
