National Instruments VME-MXI VMEbus Extender
Features

• Interfaces the VMEbus to the MXIbus
• Extends VMEbus to Multiple Mainframes
• Allows Multiple VMEbus Mainframes to Appear as a Single VMEbus System
• Supports Dynamic Configuration of MXIbus Devices

The National Instruments VME-MXI interface is a single-slot, 6U VMEbus board. It interfaces the VMEbus to the MXIbus by using address mapping to transparently translate bus cycles on the VMEbus to the MXIbus and vice versa. This interface can be installed in any 6U slot in a VMEbus chassis or in any slot except Slot 0 of a B-size, C-size or D-size VXIbus mainframe. The VME-MXI has 4 address windows that map bus cycles into and out of the VMEbus chassis.

The VME-MXI has the following features:
– extends VMEbus to multiple mainframes, external MXIbus-equipped instruments, and external MXIbus-equipped personal computers
– provides integrated block mode for high-performance data users
– allows multiple VMEbus mainframes to appear as a single VMEbus system
– supports dynamic configuration of MXIbus devices
– no restrictions on Commander/Servant hierarchy or physical location of devices
– provides optional interlocked bus operation for prevention of deadlock conditions
– is fully compatible with VMEbus, VXIbus, and MXIbus specifications
