National Instruments Corporation G-5 VXI-MIO Series User Manual

default setting A default parameter value recorded in the driver. In many cases,

the default input of a control is a certain value (often 0) that means

use the current default setting. For example, the default input for

a parameter may be do not change current setting, and the default

setting may be no AMUX-64T boards. If you do change the value

of such a parameter, the new value becomes the new setting. You

can set default settings for some parameters in the configuration

utility or by manually using switches located on the device.

device (1) A plug-in data acquisition board, card, or pad that can contain

multiple channels and conversion devices. Plug-in boards,

PCMCIA cards, and devices such as the DAQPad-1200, which

connects to your computer parallel port, are all examples of DAQ

devices. (2) A component of a VXIbus system, normally one

VXIbus board. However, multiple-slot devices and multiple-

device modules can operate on a VXIbus system as a single

device. Some examples of devices are computers, multimeters,

multiplexers, oscillators, operator interfaces, and counters.

DGND digital ground signal

DIFF differential mode

differential input An analog input consisting of two terminals, both of which are

isolated from computer ground, whose difference is measured.

DIO digital input/output

dithering The addition of Gaussian noise to an analog input signal.

DLL Dynamic Link Library—A software module in Microsoft

Windows containing executable code and data that can be called

or used by Windows applications or by other DLLs. Functions and

data in a DLL are loaded and linked at run time when they are

referenced by a Windows application or other DLLs.

DMA Direct Memory Access—A method by which data can be

transferred to/from computer memory from/to a device or

memory on the bus while the processor does something else.

DMA is the fastest method of transferring data to/from computer

memory.

DNL differential nonlinearity—A measure in LSB of the worst-case

deviation of code widths from their ideal value of 1 LSB.

DRAM Dynamic RAM

drivers/driver software Software that controls a specific hardware device such as a DAQ

board.
