National Instruments PC-OPDIO-16 Manuale Utente

To install NI-DAQ for Windows, run the 

SETUPWIN

 program on Disk 1.  One way to do this is

to select the File menu from the Program Manager Window, then select Run... and type in

a:\setupwin

, assuming a: is the floppy disk drive containing Disk 1.  When prompted, select

the Install/Upgrade NI-DAQ for Windows option.

Setupwin

 will install examples programs and support files for a variety of languages and

compilers.  Choose all of the languages/compilers you plan to use.  The NI-DAQ installer
examines your computer system to determine the system-dependent files that you need.

After installing NI-DAQ, continue by reading the Software Configuration section to configure
your PC-OPDIO-16.

Before you begin your NI-DAQ application development, you must configure your
PC-OPDIO-16.  NI-DAQ needs the device configuration information to program your hardware
properly.

You can configure your PC-OPDIO-16 board using 

DAQCONF

 or 

WDAQCONF

.  

DAQCONF

 and

WDAQCONF

 are applications that you can use to view and configure your DAQ boards and SCXI

hardware for NI-DAQ to use.  

DAQCONF

 is a DOS-based application while 

WDAQCONF

 is

Windows-based.  If you are using NI-DAQ in DOS, you need to run 

DAQCONF

.  If you are using

NI-DAQ in Windows or LabWindows/CVI, you should run 

WDAQCONF

.  Refer to the

appropriate section that follows according to the system you are using.

The National Instruments switchless devices support switchless and jumperless configuration in
DOS and Windows.  All resources including base address on these devices are fully software
configurable.  No jumpers or DIP switches are needed to configure any of these resources.

The NI-DAQ installer will install a standalone executable called 

NI-PNP.EXE

 in the boot

directory of your root drive.  This program detects and configures any switchless devices you
have in your computer.  The program will run every time you boot from your 

autoexec.bat

file. After configuring your switchless hardware in the system, the program will generate an

NI-PNP.INI

 file in the same directory.  This file contains information about the National

Instruments devices in your system, including switchless devices.

The DAQ configuration utility (

WDAQCONF

 or 

DAQCONF

) will read the 

NI-PNP.INI

 for

information and will automatically configure any switchless devices you have in your computer.
The utility will also deconfigure any previously configured switchless device that you have
removed from your computer.  Running the configuration utility after installing a new switchless
device is important because you will be able to obtain a mapping for the newly installed device
into an NI-DAQ device number.
