The NI 779500-03 is a 3-meter MXI-Express cable delivering high-bandwidth serial communication between a host computer and PXI or PXI Express chassis. This Gen 1 x1 interface enables transparent control of PXI systems from PCs equipped with PCI Express slots, supporting both single and multiple chassis configurations with sustained throughput of 110 MB/s (1 chassis) and 160 MB/s (2 chassis).
Technical Specifications
Interface & Communication

• Sustained throughput: 110 MB/s (1 chassis), 160 MB/s (2 chassis)
Physical Characteristics
• Cable length: 3 meters (9.84 feet)
• Connector type: MXI-Express Plug to Plug
• Copper conductor, shielded
• Black color
– Key Features
• Direct host-to-chassis connectivity eliminates protocol overhead—data transfer appears transparent to applications
• Shielded construction minimizes electromagnetic interference in dense instrumentation environments
• Supports multi-chassis systems for expanded I/O and modular architectures
• Fixed 3-meter length suitable for desktop-to-chassis and rack-mounted configurations
– Typical Applications
• Control of PXI and CompactPCI systems from desktop and server platforms
• High-performance data acquisition across distributed chassis
• Modular instrument configurations requiring extended communication bandwidth
• Integration of PXI instrumentation into existing PC-based test environments
– Compatibility & Integration
Host Systems: PCs with available PCI Express slots
Target Devices: PXI and PXI Express chassis
Required Support Software: PXI Platform Services Driver (for chassis identification, trigger routing, slot detection)
Optional Configuration: MXI-Express BIOS Compatibility software may be required for host BIOS setup
Critical Operational Note: Do not disconnect the cable while the system is powered on—removal causes system hangs and communication errors. If disconnection occurs, reconnect and restart the computer.
