National Instruments 779524-01 Pentium III Processor Controller

The National Instruments 779524-01 (Model Name: VXIpc-875B) is a high performance embedded controller designed for VXI systems. It is powered by an Intel Pentium III processor that offers flexibility and reliability for demanding industrial applications. The controller operates at speeds of 1.4 GHz and provides sufficient computing power for a wide range of control tasks. It is integrated with the Intel 815E chipset and ensures optimal performance and compatibility with various peripherals and system components.

The 779524-01 controller supports a maximum of 512 MB PC133 SDRAM memory that is expandable through two SO-DIMM slots. This memory is critical for handling data-intensive tasks such as real time processing and control in VXI applications. The embedded Intel 82815 graphics controller leverages dynamic memory video technology (DMVT) and dynamically manages video memory to improve system performance especially when working with high-speed PC133 memory. Networking capabilities are built-in featuring 10/100BaseT Ethernet connectivity via an Intel 82562 Platform LAN controller. This allows for seamless integration into local networks and enables remote control and data acquisition over Ethernet. The controller includes two USB 1.1-compliant ports that make it compatible with a wide range of peripheral devices.

The 779524-01 controller’s Wide Ultra2 SCSI interface provided by the LS153C895A PCI controller supports transfer speeds up to 80 MB/s. It is ideal for high-speed data retrieval and storage. The system also includes a floppy drive and can boot from an ATA flash memory PC card or over the network through PXE. To further extend its functionality, the NI 779524-01 model offers expansion via two PC card slots. This allows users to add additional peripherals such as ATA flash memory or specialized control interfaces. The controller uses PCI MITE and TNT4882 ASIC for GPIB communication. This enables high-speed control of external instruments with transfer speeds of up to 8 MB/s when utilizing the HS488 protocol.

This processor controller is designed to operate efficiently in industrial environments with a mean time between failures (MTBF) of 86,000 hours. It supports a wide operating temperature range of 5 to 50 °C and can handle non-condensing humidity levels from 10 % to 90 %.
