Chapter 2 Installation and Configuration
Basic PXI System Configuration
The Platform Services 2.5.1 (or higher) software provided on the NI Driver CD-ROM will
automatically detect your PXIe-1073 chassis. To manually configure your chassis follow the
steps outlined below. Refer to Figure 2-7 while completing the following steps:
1.
Launch MAX.
2. In the Configuration tree, click the Devices and Interfaces branch to expand it.
3. If the PXI system controller has not yet been configured, it is labeled PXI System
(Unidentified) . Right-click this entry to display the pop-up menu, then select the
appropriate system controller model from the Identify As submenu.
4. Click the PXI system controller. The chassis (or multiple chassis, in a multichassis
configuration) is listed below it. Identify each chassis by right-clicking its entry, then
selecting the appropriate chassis model through the
Identify As submenu. Further
expanding the PXI System branch shows all devices in the system that can be recognized
by NI-VISA. When your system controller and all your chassis are identified, the required
pxisys.ini
or
pxiesys.ini
file is complete.
5. Apply the chassis number labels (shown in Figure 2-8) included with your kit to each
chassis in your PXI system, and write in the chassis number accordingly in the white space.
Figure 2-7.
Chassis Number Label
The PXI specification allows for many combinations of PXI chassis and system modules. To
assist system integrators, the manufacturers of PXI chassis and system modules must document
the capabilities of their products. PXI Express devices must provide a driver and
.ini
file for
identification. These files are provided as part of the PXI Platform Services software included
with your system controller. The minimum documentation requirements for PXI-1 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 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
