The
os
directory contains a subdirectory corresponding to the operating
system installed on your computer.
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.
PXI Express Features
PXI Express Trigger Connectivity
The SMB connector on the NI PXIe-8105 front panel can connect to or
from any PXI 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 Chassis Configuration
The PXI Platform Services software included with your controller
automatically identifies your PXI Express system components to generate
a
pxiesys.ini
and
pxisys.ini
file. You can configure your entire PXI
system and identify PXI-1 chassis through Measurement & Automation
Explorer (MAX), included with your controller. MAX creates the
pxiesys.ini
and
pxisys.ini
file, which define your PXI 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 triggers, refer to
KnowledgeBase 3TJDOND8 at

.
The configuration steps for single or multiple-chassis systems are the same.
