National Instruments Corporation xi PC-LPM-16/PnP User Manual

Non-PnP Non-PnP (non-Plug and Play) means that the board requires you to

manually configure the product’s base address and interrupt level with

switches and jumpers. You must perform this configuration before

installing the board into your computer.

PC PC refers to the IBM PC/XT, PC AT, Personal System/2 Models 25

and 30, and laptop compatible computers.

PC-LPM-16/PnP PC-LPM-16/PnP refers to both the Plug and Play and the non-Plug and

Play versions of the board.

PC-LPM-16PnP PC-LPM-16PnP refers to the Plug and Play version of the board.

PC-LPM-16 PC-LPM-16 refers to the non-Plug and Play version of the board.

PnP PnP (Plug and Play) means that the board is fully compatible with the

industry-standard Plug and Play ISA Specification. All bus-related

configuration is performed through software, freeing you from

manually configuring jumpers or switches to set the product’s base

address and interrupt level. Plug and Play systems automatically

arbitrate and assign system resources to a PnP product.

Abbreviations, acronyms, metric prefixes, mnemonics, symbols, and

terms are listed in the

National Instruments Documentation

The

PC-LPM-16/PnP User Manual

is one piece of the documentation

set for your DAQ or SCXI system. You could have any of several types

of manuals depending on the hardware and software in your system.

Use the manuals you have as follows:

•

Getting Started with SCXI

—If you are using SCXI, this is the first

manual you should read. It gives an overview of the SCXI system

and contains the most commonly needed information for the

modules, chassis, and software.

• Your SCXI hardware user manuals—If you are using SCXI, read

these manuals next for detailed information about signal

connections and module configuration. They also explain in

greater detail how the module works and contain application hints.

• Your DAQ hardware documentation—This documentation has

detailed information about the DAQ hardware that plugs into or is

connected to your computer. Use this documentation for hardware
