NIDSP

 is the name you specify during setup.

The 

SETUP

 program prompts you for information including the drive letter and directory in which you have

installed the standard LabVIEW package.  The program also verifies that your hard disk has enough space to hold
the NI-DSP for LabVIEW for Windows files.

If you choose Custom Installation, 

SETUP

 installs only the files you specify.

There are several board configuration parameters that must be established before an NI-DSP application can execute
properly.  These parameters are the board ID number, the board subtype, the base address, the interrupt level, the
DMA channel, and the pathname of the DSP Library files.  These parameters are established differently depending
on whether you are installing the AT-DSP2200 in an ISA (or AT) bus computer or an EISA bus computer.

A configuration utility is supplied with the LabVIEW data acquisition software for establishing all the configuration
parameters on ISA bus computers.  This utility, called 

WDAQCONF.EXE

, saves the configuration parameters in a file

named 

WDAQCONF.CFG

.  Use the 

WDAQCONF

 utility to assign a board ID number to your AT-DSP2200, to choose

the memory subtype (either 64 Kwords or 

≥

128 Kwords), to set the base address, interrupt level, and DMA channel,

and to specify the pathname of the DSP Library file.

Two DSP Library files are supplied with your NI-DSP software–

LV2200S.OUT

 and 

LV2200.OUT

.

LV2200S.OUT

 is intended for use with the 64 Kword version of the AT-DSP2200.  

LV2200.OUT

 is intended for

use with any other version of the board.  With the 

WDAQCONF

 utility, you can enter a complete path that will include

the DSP Library file name.  If you enter complete pathnames, you can configure the NI-DSP software to
automatically load custom versions of the DSP Library files.

If you installed the Data Acquisition Library of LabVIEW, you can find 

WDAQCONF.EXE

 of your 

LabVIEW

directory.  From Windows, you run 

WDAQCONF.EXE

 by double-clicking on its icon.

Installing the AT-DSP2200 board on an EISA bus computer involves two different configuration utilities.

•

A system configuration utility is supplied with your computer by your computer vendor.  This utility, along with
the 

!NIC1100.CFG

 EISA configuration file installed by the LabVIEW 

SETUP

 program, is used to assign a

slot number to the AT-DSP2200, to choose the memory subtype (either 64 Kwords or 

≥

128 Kwords), and to set

the base address, interrupt level, and DMA channel.

There are typically two methods for running your EISA system configuration utility.

1.

Boot from the diskette containing the utility and place a copy of the 

!NIC1100.CFG

 file on this diskette.

2.

Run the utility from a directory on your hard disk and place a copy of the 

!NIC1100.CFG

 file in this

directory.  The EISA system configuration utility is typically named 

CF.EXE

.

•

You must use the 

WDAQCONF

 utility to enter the DSP Library file pathname.  You can only do this after

completing the EISA system configuration.  Refer to the information concerning the establishment of this
pathname in the previous section titled, Installation on an ISA (or AT) Bus Computer.

Before using NI-DSP, you must run 

WDAQCONF.EXE

 to configure your DSP board.

For more information about board configuration, refer to Chapter 1, Introduction and Configuration, of the
LabVIEW Data Acquisition VI Reference Manual.
