VXI-MIO Series User Manual
meters
The chassis of a VXIbus system that mechanically contains VXI
modules inserted into the backplane, ensuring that connectors fit
properly and that adjacent modules do not contact each other. It
also provides cooling airflow, and ensures that modules do not
disengage from the backplane due to vibration or shock.
megabytes of memory
A memory storage device that has configuration registers.
multifunction I/O
A National Instruments custom ASIC. A sophisticated dual-
channel DMA controller that incorporates the Synchronous MXI
and VME64 protocols to achieve high-performance block transfer
rates.
Typically a board assembly and its associated mechanical parts,
front panel, optional shields, and so on. A module contains
everything required to occupy one or more slots in a mainframe.
most significant bit
A property of an operating system in which several processes can
be run simultaneously.
multiplexer—A switching device with multiple inputs that
sequentially connects each of its inputs to its output, typically at
high speeds, in order to measure several signals with a single
analog input channel.
