PXI System Configuration with MAX
Configuration of the PXI system is handled through Measurement &
Automation Explorer (MAX), included on the NI Driver CD-ROM
packaged with your kit. MAX creates the
pxisys.ini file which defines
the layout and parameters of your PXI system. After installing the software
on the NI Driver CD-ROM, the MAX icon will be present on the desktop.
The configuration steps for single- or multiple-chassis systems are the
same.
