The National Instruments PXIe-8379 is an interface card that connects a host computer to a PXI Express chassis using Thunderbolt 2. It provides a high speed remote control link, allowing the host computer to control PXI Express modules as if they were installed in the computer. The card is used in automated test, laboratory measurement, and industrial systems where the PXI hardware must be placed near the device under test while the computer remains in a control area.
Remote control separates computing resources from measurement hardware. This separation supports flexible test station layout, easier host upgrades, and centralized software management. The PXIe-8379 brings Thunderbolt 2 connectivity to this architecture, offering high bandwidth over a compact cable.
Thunderbolt 2 Connectivity
The card provides a Thunderbolt 2 link between the host and the PXI Express chassis. Thunderbolt 2 supports high data throughput and is available on many computers and laptops. Engineers should verify host compatibility, cable type, and driver support before deployment.
Cable length and routing should be planned for the installation. Connectors should be fully seated and secured. Documentation of host and chassis settings helps maintenance.
PXI Express Integration
The PXIe-8379 installs in a compatible PXI Express chassis and connects to the backplane. It allows the host to access PXI Express modules through the remote link. Engineers should verify slot compatibility, power requirements, and cooling.
The link should be planned for the required bandwidth. Data intensive applications may require careful selection of modules and data reduction to fit within the link capacity.
System Integration
The card integrates with PXI Express chassis, controllers, and modules. It can be used with a range of instruments and DAQ modules. Engineers should verify software support and driver versions for the host operating system.
For automated test, remote control supports centralized computing and easier software management. The chassis can be located in a test cell or rack while the computer remains in a laboratory or control room.
Applications
The PXIe-8379 is suited to automated test, laboratory instrumentation, production validation, and research systems. It supports flexible placement of PXI Express hardware and centralized host computing.
Installation and Maintenance
Installation requires installing the card, connecting the Thunderbolt 2 cable, and verifying link status. Power should be off during installation. Maintenance includes checking cable connections, verifying link status, and reviewing software configuration.
Summary
The National Instruments PXIe-8379 Interface Card provides a Thunderbolt 2 connection between a host computer and a PXI Express chassis. It supports remote control, flexible test station layout, and high speed communication. The PXIe-8379 is a practical interface for engineers who need remote PXI Express control.
