NI PXIe-1071 User Manual
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-1071 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-1071 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
