The file system of the cRIO-9068 follows conventions established for UNIX-style operating
systems. Other LabVIEW Real-Time targets follow Microsoft Windows-style conventions. In
order to facilitate the porting of applications from those targets, this target supports the
Windows-style /C home directory. This path is bound to the UNIX-style directory /home/
lvuser.
Various LabVIEW Real-Time system files which would be accessible from C: (or /C) on
other LabVIEW Real-Time targets are found in different locations on this target.
UNIX-style file systems support the concept of a symbolic link, which allows access to a file
using an alternative file path. For example, it is possible to link /C/ni-rt/system, where
dynamic libraries are deployed on other LabVIEW Real-Time targets, to /usr/local/lib,
where they are stored on the cRIO-9068, if the application requires this.

Mounting the Device
To obtain the maximum allowable ambient temperature of 70 °C, you must mount the
cRIO-9068 horizontally on a flat, metallic, vertical surface such as a panel or wall. You can
mount the cRIO-9068 directly to the surface or use the NI Panel Mounting Kit. The following
figure shows the cRIO-9068 mounted horizontally.

You can also mount the cRIO-9068 in other orientations, on a nonmetallic surface, on a
35-mm DIN rail, on a desktop, or in a rack. Mounting the cRIO-9068 in these or other
configurations can reduce the maximum allowable ambient temperature and can affect the
typical accuracy of modules in the cRIO-9068. For more information about typical accuracy
specifications for C Series modules and temperature deratings caused by different mounting
configurations, visit ni.com/info and enter the Info Code criotypical.
Caution Make sure that no C Series modules are in the cRIO-9068 before
mounting it.
