Data Acquisition-Related Configuration
The PC-OPDIO-16 supplies eight channels of optically isolated digital input and eight channels
of optically isolated digital output at the I/O connector.
NI-DAQ Software Installation
This following sections describe the installation of NI-DAQ on different platforms, including
DOS, LabVIEW, LabWindows/CVI, and Windows. Refer to the appropriate section and follow
the instructions to install the NI-DAQ software.
NI-DAQ Installation for DOS
The NI-DAQ distribution diskettes contain the installation utility SETUPDOS.EXE. Running
this installation utility copies the appropriate files to your computer. For example, if your
installation diskette is in drive A, type the following:
a:\setupdos
After installing NI-DAQ, continue by reading the Software Configuration section later in this
chapter to configure your PC-OPDIO-16.
NI-DAQ Installation for LabVIEW
The LabVIEW installation program may have installed the NI-DAQ software for you. However,
the NI-DAQ software that is included with your DAQ hardware may be a more recent revision
than the NI-DAQ software that LabVIEW installed.
After you have installed LabVIEW, you should run the NI-DAQ Windows installer
SETUPWIN.EXE, which will check the NI-DAQ version that LabVIEW installed against this
NI-DAQ version to ensure that the newest version is installed.
Note: You need NI-DAQ Version 4.8 or later to use your PC-OPDIO-16. Since LabVIEW
Version 3.1 installs NI-DAQ Version 4.6.1, you will need to install the NI-DAQ
software included with your PC-OPDIO-16 board if you are using LabVIEW Version
3.1 or earlier.
To upgrade NI-DAQ for LabVIEW, 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 Upgrade NI-DAQ for LabVIEW option.
Depending on your LabVIEW version, it may be necessary for NI-DAQ to update some of the
LabVIEW data acquisition VIs. If so, carefully follow the instructions given in the NI-DAQ
installer and the README.DAQ file.
