National Instruments 777942-01

The National Instruments part number 777942-01, also known as the MXI-3 Interface Kit, is designed to facilitate direct control of PXI or CompactPCI systems from a computer via a robust software and hardware interface. This kit incorporates the PXI-PCI8330 model, which includes a PCI-8330 plug-in board, a PXI-8330 module, and an MXI-3 cable, enabling seamless communication across multiple systems. The MXI-3 technology supports daisy-chaining of up to 254 devices and adheres to the PCI-to-PCI bridging specification, which allows for various configurations, including star setups.

The interface operates without the need for additional software for standard functions and supports copper cable lengths of 2 to 10 meters, making it cost-effective for typical applications. For extended distances or electrical isolation, fiber-optic cable options are also available, though at a higher cost. When connected via copper cabling, the data link can achieve impressive serial data rates of up to 1.5 Gbit per second. The kit's hardware features include the NI MXI-3 ASIC, Serial Transmitter, Serial Receiver, and a High-Speed Serial Data Connector (HSSDC) receptacle, and it operates across various operating systems such as Sun Solaris, Microsoft Windows, and Apple Mac OS.

Physical dimensions of the PCI model are 4.2 x 6.9 inches with a weight of 5 ounces, while the PXI model measures 3.9 x 6.3 inches and weighs 8 ounces. The expected Mean Time Between Failures (MTBF) is approximately 1,080,000 hours for the PXI-8330 and 1,130,000 hours for the PCI-8330. This product is discontinued but remains available for purchase through Apex Waves.
