NI-VXI Software Installation and Configuration
Step 3. Change the Path for the Utility Files (Optional)
If you want to run the NI-VXI utilities from any directory other than /usr/nivxi, set the
environment variable NIVXIPATH to the main directory containing the /hlp and /tbl
subdirectories.
Note:
The manner for setting up the environment variable depends on the shell you are using.
Consult the online manual pages for information on setting up an environment variable.
For example, for the Bourne shell (the default shell on ISC 386/ix), if your main directory for the
NI-VXI software is /usr/nivxi, add the following statements in the .profile file in your
home directory:
NIVXIPATH=/usr/nivxi
export
If you are using the C-Shell (csh), and your main directory for the NI-VXI software is
/usr/nivxi, add the following statement in your .cshrc file in your home directory:
set
If you set the NIVXIPATH environment variable in this manner, the NI-VXI utilities can access
table, configuration and help files from the /usr/nivxi/tbl and /usr/nivxi/hlp
directories. You can also add this directory to your default search path by modifying the PATH
environment variable.
Configuring the NI-VXI Software
Run the vxitedit device configuration utility if you need to make any changes to the default
software configuration. You can also run vxitedit if you just want to examine the software
configurations.
The following sections describe how to modify and/or view the configuration information for
the AT-MXI board. To modify or view manufacturer names, model names, or device ID
associations, or to obtain more information on non-VXI devices, refer to the NI-VXI Text
Utilities Reference Manual.
