The file system of the cRIO-9039 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-9039, if the application requires this.

Installing the Module Immobilization Accessory
The Module Immobilization accessory, part number 158533-01, ensures that the C Series
module latches cannot be retracted and modules cannot be removed from a system. The
Module Immobilization accessory provides extra system assurance and security when shipping
and installing systems, and prevents accidental removal from a system during operation.
When using the Module Immobilization accessory, NI recommends installing the accessory
prior to mounting the system in any enclosure because the accessory requires tool access to the
top, right, and bottom of the cRIO-9039.
What to Use
• cRIO-9039
• C Series modules
• Module Immobilization accessory kit, 158533-01
–
Module immobilization bracket
– Installation screws
1
• M4 x 0.7 button-head screw, 8 mm
• M3 x 0.5 flat-head screws (x2), 10 mm
• Torx T10/T10H driver
• Torx T20/T20H driver
What to Do
Complete the following steps to install the Module Immobilization accessory.
1
The Module Immobilization accessory kit includes two sets of screws. One set is a standard set of
screws that require a standard driver type, Torx T10 and T20. The other set is a tamper-resistant set
of screws that require a security driver type, Torx T10H and T20H. Use the tamper-resistant set to
help prevent unintended modification of the system.
