The NI 9157 and NI 9159 MXI-Express RIO chassis and NI 9148 Ethernet RIO chassis extend the company’s offering of high-channel-count expansion chassis on a variety of buses. Built on reconfigurable I/O (RIO) technology, the chassis deliver the benefits of field programmable gate array (FPGA)-based hardware and C Series I/O to apps requiring hundreds or thousands of channels. Each expansion chassis contains a Xilinx FPGA that is programmable with the LabVIEW FPGA Module. The 9159 MXI-Express RIO 14-slot expansion chassis with onboard Virtex-5 FPGAs addresses large applications with high channel counts, mixed I/O, and custom signal processing and control algorithms. The chassis is viable for hardware-in-the-loop testing, industrial machine monitoring, and research applications. The NI 9148 8-slot Ethernet expansion chassis adds distributed I/O to RIO systems. Via CAT 5 Ethernet cabling, it communicates with NI CompactRIO, real-time PXI controllers, the NI industrial controller, or any networked Windows PC. It includes onboard FPGA and LabVIEW FPGA software. With either chassis, engineers can also use more than 50 third-party C Series I/O modules including wireless modules based on 802.11, GPS, Edge, and other technologies. Prices for the MXI-Express RIO and Ethernet RIO chassis start at $4,499 and $999, respectively. NATIONAL INSTRUMENTS, Austin, TX. (888) 280-7645.
