Installation and Configuration
The capability documentation for a PXI-1 chassis is contained in a
chassis.ini
file provided
by the chassis manufacturer. The information in this file is combined with information about the
system controller to create a single PXI-1 system initialization file called
pxisys.ini
(PXI System Initialization). The NI system controller uses MAX to generate the
pxisys.ini
file from the
chassis.ini
file.
Device drivers and other utility software read the
pxiesys.ini
and
pxisys.ini
file to
obtain system information. For detailed information about initialization files, refer to the PXI
specification at
www.pxisa.org
.
Using System Configuration and Initialization
Files
The PXI Express specification allows many combinations of PXI Express chassis and system
modules. To assist system integrators, the manufacturers of PXI Express chassis and system
modules must document the capabilities of their products. The minimum documentation
requirements are contained in
.ini
files, which consist of ASCII text. System integrators,
configuration utilities, and device drivers can use these
.ini
files.
The capability documentation for the NI PXIe-1082DC chassis is contained in the
chassis.ini
file on the software media that comes with the chassis. The information in this
file is combined with information about the system controller to create a single system
initialization file called
pxisys.ini
(PXI System Initialization). The system controller
manufacturer either provides a
pxisys.ini
file for the particular chassis model that contains
the system controller or provides a utility that can read an arbitrary
chassis.ini
file and
generate the corresponding
pxisys.ini
file. System controllers from NI provide the
pxisys.ini
file for the NI PXIe-1082DC chassis, so you should not need to use the
chassis.ini
file. Refer to the documentation provided with the system controller or to
ni.com/support
for more information on
pxisys.ini
and
chassis.ini
files.
Device drivers and other utility software read the
pxisys.ini
file to obtain system
information. The device drivers should have no need to directly read the
chassis.ini
file.
For detailed information regarding initialization files, refer to the PXI Express specification at
www.pxisa.org
