Installation and Configuration
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 PXIe-1066DC 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
PXIe-1066DC 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
