National Instruments 779524-01

The National Instruments 779524-01, also known as the VXIpc-875B, is a high-performance embedded controller specifically designed for VXI systems. Equipped with an Intel Pentium III processor operating at 1.4 GHz, this controller delivers exceptional reliability and flexibility suited for demanding industrial applications. The system integrates the Intel 815E chipset, ensuring optimal performance and compatibility with various peripherals and system components.

The 779524-01 supports a maximum of 512 MB of PC133 SDRAM, expandable through two SO-DIMM slots, thereby effectively handling data-intensive tasks, including real-time processing and control within VXI applications. The embedded Intel 82815 graphics controller enhances system performance through dynamic memory video technology (DMVT), particularly beneficial when utilizing high-speed PC133 memory. Networking capabilities include built-in 10/100BaseT Ethernet connectivity via the Intel 82562 Platform LAN controller, facilitating seamless local network integration and enabling remote control and data acquisition.

Additionally, the controller provides two USB 1.1-compliant ports for compatibility with a broad range of peripheral devices. The Wide Ultra2 SCSI interface, supported by the LS153C895A PCI controller, achieves transfer speeds of up to 80 MB/s, making it well-suited for high-speed data retrieval and storage. The unit is further enhanced with a floppy drive and supports booting from an ATA flash memory PC card or over the network via PXE. For expansion capabilities, the NI 779524-01 features two PC card slots that allow users to incorporate additional peripherals, including ATA flash memory or specialized control interfaces.

Communication with external instruments is facilitated through PCI MITE and TNT4882 ASICs for GPIB communication, providing high-speed control with transfer rates up to 8 MB/s when using the HS488 protocol. Designed to operate efficiently in industrial environments, this processor controller boasts a mean time between failures (MTBF) of 86,000 hours and supports an operational temperature range of 5 to 50 °C, along with non-condensing humidity levels from 10% to 90%. The physical dimensions of the unit are 233.35 mm x 340 mm (9.187 in x 13.386 in) and it has a weight of 2.2 kg (4.9 lb). The product comes with a warranty period of 2 to 3 years, ensuring dependable functionality for critical automation tasks.
