specific drive finish before removing the device. Refer to the LabVIEW Help for moreinformation.The file system of the cRIO-9068 follows conventions established for UNIX-style operatingsystems. Other LabVIEW Real-Time targets follow Microsoft Windows-style conventions. Inorder to facilitate the porting of applications from those targets, this target supports theWindows-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) onother 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 fileusing an alternative file path. For example, it is possible to link /C/ni-rt/system, wheredynamic 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.For more information, visit ni.com/info and enter the Info Code RT_Paths.Mounting the DeviceTo obtain the maximum allowable ambient temperature of 70 °C, you must mount thecRIO-9068 horizontally on a flat, metallic, vertical surface such as a panel or wall. You canmount the cRIO-9068 directly to the surface or use the NI Panel Mounting Kit. The followingfigure shows the cRIO-9068 mounted horizontally.Figure 6. cRIO-9068 Horizontal Mounting11. UpYou can also mount the cRIO-9068 in other orientations, on a nonmetallic surface, on a35-mm DIN rail, on a desktop, or in a rack. Mounting the cRIO-9068 in these or otherconfigurations can reduce the maximum allowable ambient temperature and can affect thetypical accuracy of modules in the cRIO-9068. For more information about typical accuracyspecifications for C Series modules and temperature deratings caused by different mountingconfigurations, visit ni.com/info and enter the Info Code criotypical.Caution Make sure that no C Series modules are in the cRIO-9068 beforemounting it.14 | ni.com | NI cRIO-9068 User Manual
