    NI-VXI/VISA software media for the PCI-MXI-2 MXI-2 Description MXI-2 is the second generation of the National Instruments MXIbus product line. The MXIbus is a general-purpose, 32-bit, multimaster system bus on a cable. MXI-2 expands the number of signals on a standard MXI cable by including VXI triggers, all VXI interrupts, CLK10, and all of the utility bus signals (SYSFAIL*, SYSRESET*, and ACFAIL*).

  • Page 18: Hardware Description

    MXI block data transfers which surpass previous block data throughput benchmarks. The new synchronous MXI block protocol increases MXI-2 throughput to a maximum of 33 MB/s between two MXI-2 devices. All National Instruments MXI-2 boards can initiate and respond to synchronous MXI block cycles. Note In the remainder of this manual, the term MXIbus refers to MXI-2.

  • Page 19: Software Description

    NI-VISA has a comprehensive library of software routines not only for VXI/VME programming, but also for GPIB, GPIB-VXI, and serial. You can use this software to program instruments connected via different types of interfaces. © National Instruments Corporation VXI/VME-PCI8026 for Linux...

  • Page 20: Optional Software

    Optional Software Your VXI/VME-PCI8026 kit includes the NI-VXI/VISA bus interface software. In addition, you can use National Instruments LabVIEW to ease your programming task. This standardized program matches the modular virtual instrument capability of VXI and can reduce your VXI/VMEbus software development time.

    Chapter 6 NI-VXI Configuration Utility Note If you do not want to lose 4 KB of DRAM you can get around this limitation by setting the Requested Memory option to double the amount that is installed on the VXI/VME-MXI-2, because the DRAM is aliased throughout the remainder of the requested memory space.

  • Page 83: Request Level

    Chapter 6 NI-VXI Configuration Utility Request Level The VXI/VME-MXI-2 uses one of the four VMEbus request levels (0 to 3) to request use of the VME Data Transfer Bus (DTB). The VXI/VME-MXI-2 requests use of the DTB whenever an external MXIbus device, such as a PCI-based computer with a PCI-MXI-2 interface, attempts a transfer that maps into the VXI/VMEbus mainframe.

  • Page 85: Transfer Limit

    Chapter 6 NI-VXI Configuration Utility Normally, when a cycle maps from the MXIbus to the VXI/VMEbus, any retry response received on the VXI/VMEbus is passed to the MXIbus. If you enable the Auto Retry feature, the VXI/VME-MXI-2 automatically retries any VXI/VME cycle that receives a retry response instead of passing a retry response on to the MXIbus.
