NI PXIe-8880 User Manual
Drivers and Software
If you purchased a system preinstalled with Windows, your hard drive includes a directory called
images
in its root that contains software and soft copies of manuals for the peripherals. The
directory structure under the
images
directory is logically organized into several levels.
In the
images
directory are
drivers
and
NIDRIVERS
directories. The
drivers
directory
contains driver installers for the system peripherals. These files and directories are copied
exactly from the manufacturer distribution disks, so the naming conventions vary from
peripheral to peripheral. The
NIDRIVERS
directory contains the GPIB and PXI Platform
Services drivers preinstalled on the controller.
PXI Express Features
PXI Express Trigger Connectivity
The SMB connector on the NI PXIe-8880 front panel can connect to or from any PXI Express
backplane trigger line. A trigger allocation process is needed to prevent two resources from
connecting to the same trigger line, resulting in the trigger being double-driven and possibly
damaging the hardware. At the time of this manual’s publication, this software is not
yet available for Windows. Contact National Instruments for more information.
PXI Express Chassis Configuration
The PXI Express Platform Services software installed on your controller and available on the
National Instruments Driver DVD
or
PXI Platform Services CD
included with your kit
automatically identifies your PXI Express system components to generate a
pxiesys.ini
and
pxisys.ini
file. You can configure your entire PXI Express system through Measurement &
Automation Explorer (MAX), included with your controller. MAX creates the
pxiesys.ini
and
pxisys.ini
file, which define your PXI Express system parameters. MAX also provides
an interface to route and reserve triggers so dynamic routing, through drivers such as DAQmx,
avoids double-driving and potentially damaging trigger lines. For more information about
routing and reserving PXI Express triggers, refer to KnowledgeBase 3TJDOND8,
