The NI 785550-03 is a 3-meter x8 MXI-Express Gen-3 cable engineered for high-speed data communication between host interfaces and PXI or PXI Express chassis. Built with high-quality copper construction, this cable supports PCI Express Gen-3 speeds up to 8.0 Gb/s per lane per direction across its eight lanes. The 72-pin male MXI-Express x8 connector enables transparent operation with PXI Express devices—no additional software required when PXI Platform Services is installed.
Technical Specifications
• Cable length: 3 meters (9.84 feet)
• Interface: 72-pin male MXI-Express x8
• Data transfer rate: PCI Express Gen-3 (8.0 Gb/s per lane per direction)
• Construction: High-quality copper
• Weight: 0.85 kg
• Included case for storage and transport
– Key Features
• Supports multi-chassis system interconnection
• Compatible with cabled PCI Express specification (PCI-SIG)
• Allows physical separation of measurement or automation systems from host PC
• Flexible port configurations enable bandwidth prioritization or high fanout deployment
• When using multiple cables for a single link, all cables must be the same length
– Typical Applications
• Connecting host PCI Express interfaces to remote PXI or PXI Express chassis
• Controlling multiple PXI Express or CompactPCI Express chassis from a single PCI Express-based PC or PXI Express embedded controller
• Extending measurement system distances while maintaining Gen-3 performance
– Compatibility & Integration
The cable connects to PXIe-8398 or PXIe-8399 PXI remote control modules using Gen-3 x8 copper standards. Compatible with PCI Express-based host interface cards such as the PCIe-8398. Avoid tight bending at small radii, as internal damage may degrade communication speed and data quality. Not recommended for use in toxic or corrosive environments that may affect cable insulation.
