The NI MXI Type M3 180761-01 is a 1-meter bus cable that extends the MXIbus between National Instruments mainframes and MXI-compatible devices. This Type M3 variant implements the MXI-2 generation standard, delivering up to 33 MB/s synchronous block data transfers while maintaining software and hardware transparency as a PCI-to-PCI bridge. The cable carries VXI triggers, all VXI interrupts, CLK10, and utility bus signals including SYSFAIL*, SYSRESET*, and ACFAIL*, enabling integrated control across multi-device systems.
Technical Specifications
• Cable Length: 1 meter
• Bus Standard: MXI-2 (MXIbus generation)
• Data Throughput: Up to 33 MB/s (synchronous MXI block protocol)
• Signal Composition: VXI triggers, VXI interrupts, CLK10, utility bus signals (SYSFAIL*, SYSRESET*, ACFAIL*)
• Protocol Architecture: Synchronous MXI block data transfers; PCI-to-PCI bridge (transparent to software and hardware)
• Connector Type: Right-angle point to right-angle daisy-chain configuration
– Key Features
• Backward compatible—all MXI device accesses function with MXI-2 devices
• Daisy-chain connector topology supports multi-mainframe configurations
• Right-angle connectors optimize cable routing in space-constrained installations
• Comprehensive signal extension includes triggers, interrupts, and utility control lines
• Synchronous block transfer protocol surpasses previous throughput benchmarks
– Typical Applications
• Multi-mainframe VXI system interconnection
• PXI chassis-to-chassis communication
• CompactPCI system extension
• Distributed data acquisition and instrument control networks
– Compatibility & Integration
The Type M3 cable integrates with National Instruments PXI, CompactPCI, and VXI platforms utilizing MXI-2 technology. Systems with multiple MXI devices require daisy-chain connectors. All accesses initiated by standard MXIbus devices operate transparently with MXI-2 endpoints, ensuring legacy system support while enabling performance.
