National Instruments is launching its first high-performance dual gigabit Ethernet interface for PXI Express. The NI 8234 module offers two gigabit Ethernet ports with up to 1000Mb/s transfer speeds per port for high-performance machine vision and dedicated LAN/LXI instrument control networks. The new module features a x4 PCI Express interconnect, providing up to 1GB/s bandwidth for real-time data streaming from a single PXI Express slot to give engineers and scientists more available slots for other PXI instrumentation, data acquisition and bus interface modules.
Based on the Intel 82571EB gigabit Ethernet controller, the 1000Mb/s Ethernet ports offer a substantial performance increase from 100Mb/s Fast Ethernet. Compatible with the GigE Vision camera interface for machine vision applications, the NI 8234 delivers high-speed image transmission rates for standard cabling at distances up to 100m. With GigE Vision support, the NI 8234 is NI's first PXI Express module for machine vision applications. Engineers and scientists can add GigE modules to a PXI Express system to use more GigE Vision cameras with the NI 8234. As a result, they can now stream images from multiple GigE Vision cameras simultaneously to a PXI platform.
Matthew Breit, Applications Engineer at Basler Vision Technologies, comments: “GigE Vision provides engineers and scientists with an easy, scalable platform for high-resolution and high-speed imaging. When combined with PXI Express, the new dual gigabit Ethernet bus gives them the tools to unlock the bandwidth’s full potential.”
The NI 8234 is also suitable for LAN and LXI instrument control applications using dedicated private networks. Combined with the NI LabVIEW graphical system design platform, the module simplifies the use of LAN and LXI for distributed instrument control applications by connecting multiple Ethernet-based instruments with a single interface. In addition, National Instruments offers more than 400 freely downloadable instrument drivers for LAN and LXI instruments from the NI Instrument Driver Network to further simplify instrument control.
Compatible with Ethernet standards and cabling, the new dual gigabit Ethernet interface delivers gigabit Ethernet performance with CAT 5 Ethernet cables. It automatically detects cable polarity, thereby eliminating the need for crossover and straight-through cable swapping.
