    Linux Installation Guide. 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 15: Hardware Description

    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. In the remainder of this manual, the term MXIbus refers to MXI-2.

    Chapter 3 VXI-MXI-2 Configuration and Installation VXIbus Logical Address Each device in a VXIbus/MXIbus system is assigned a unique number between 0 and 254. This 8-bit number, called the logical address, defines the base address for the VXI configuration registers located on the device. With unique logical addresses, each VXIbus device in the system is assigned 64 bytes of configuration space in the upper 16 KB of A16 space.

    Chapter 6 NI-VXI Configuration Utility VXI/VME Auto Retry The VXI/VME-MXI-2 has an automatic retry feature for cycles that map from the VXI/VMEbus to the MXIbus. By default this option is disabled. Normally, when a cycle maps from the VXI/VMEbus to the MXIbus, any retry response received on the MXIbus is passed to the VXI/VMEbus.

    The VXI/VME-MXI-2 has a limit on the number of automatic retries it will perform on any one cycle. If the limit is exceeded and the VXI/VME-MXI-2 receives another retry, it will pass a retry back to the MXIbus even though Auto Retry is enabled. © National Instruments Corporation 6-27 PCI-MXI-2 for Linux...

  • Page 90: Transfer Limit

    Chapter 6 NI-VXI Configuration Utility Transfer Limit You can use this feature to control how many data transfers the VXI/VME-MXI-2 will perform on the MXIbus before releasing it to another master device that is requesting use of the bus. The default setting holds the MXIbus for an unlimited period of time.
