Configuring Startup Options
Complete the following steps to configure the cRIO-9068 startup options in MAX.
1. In MAX, expand your system under Remote Systems.
2. Select the Startup Settings tab to configure the startup settings.
cRIO-9068 Startup Options
You can configure the following cRIO-9068 startup options.
Table 1. cRIO-9068 Startup Options
Startup Option Description
Force Safe Mode Rebooting the cRIO-9068 with this setting on starts the cRIO-9068
without launching LabVIEW Real-Time or any startup applications. In
safe mode, the cRIO-9068 launches only the services necessary for
updating configuration and installing software.
Enable Console
Out
Rebooting the cRIO-9068 with this setting on redirects the console output
to the RS-232 serial port. You can use a serial-port terminal program to
read the IP address and firmware version of the cRIO-9068. Use a null-
modem cable to connect the RS-232 serial port to a computer. Make sure
that the serial-port terminal program is configured to the following
settings:
• 115,200 bits per second
• Eight data bits
• No parity
• One stop bit
• No flow control
Disable RT
Startup App
Rebooting the cRIO-9068 with this setting on prevents any LabVIEW
startup applications from running.

Startup Option Description
Disable FPGA
Startup App
Rebooting the cRIO-9068 with this setting on prevents autoloading of any
FPGA application.
Note When you reset the cRIO-906x controller either
programmatically or by using the RESET button, you also reset
the FPGA. All FPGA I/O lines are tri-stated after a reset, and
will enter predefined states once loaded.
Enable Secure
Shell (SSH)
Logins
Rebooting the cRIO-9068 with this setting on starts sshd on the
cRIO-9068. Starting sshd enables logins over SSH, an encrypted
communication protocol.
Note Visit ni.com/info and enter the Info Code openssh for
more information about SSH.
LabVIEW
Project Access
Rebooting the cRIO-9068 with this setting on enables you to add the
target to a LabVIEW project.

Chassis Grounding Screw
The cRIO-9068 provides a chassis grounding screw.
12 | ni.com | NI cRIO-9068 User Manual

Figure 5. cRIO-9068 Grounding Screw

1. Grounding Screw
For EMC compliance, you must connect the cRIO-9068 to earth ground through the chassis
ground screw. Use wire that is 2.0 mm2 (14 AWG) solid copper wire with a maximum length
of 1.5 m (5 ft). Attach the wire to the earth ground of the electrode system of the facility.
Caution If you use shielded cabling to connect to a C Series module with a plastic
connector, you must attach the cable shield to the chassis grounding terminal using
2.0 mm2 (14 AWG) or larger wire. Attach a ring lug to the wire and attach the wire
to the chassis grounding terminal. Solder the other end of the wire to the cable
shield. Use shorter wire for better EMC performance.
For more information about ground connections, visit ni.com/info and enter the Info Code
emcground.
Internal Real-Time Clock
The cRIO-9068 contains an internal real-time clock that maintains system time when the
cRIO-9068 is powered off. The system clock of the cRIO-9068 is synchronized with the
internal real-time clock at startup. You can set the real-time clock using MAX, or you can set
the clock programmatically using LabVIEW.
Refer to the specifications on ni.com/manuals for the real-time clock accuracy specifications.
Battery
The cRIO-9068 contains a lithium cell battery that stores the system clock information when
the cRIO-9068 is powered off. There is only a slight drain on the battery when power is
applied to the cRIO-9068 power connector. The rate at which the battery drains when power is
disconnected depends on the ambient storage temperature. For longer battery life, store the
cRIO-9068 at a cooler temperature and apply power to the power connector. Refer to the
specifications on ni.com/manuals for the expected battery lifetime.
The battery is not user-replaceable. If you need to replace the battery, contact NI. Refer to the
specifications on ni.com/manuals for information about battery disposal.
File System
LabVIEW mounts USB devices to the media/sdx1 directory and creates symbolic
links /u, /v, /w, or /x to the media mount point, starting with /u if it is available. To prevent
any file corruption to external storage devices, verify that any file IO operations with the
NI cRIO-9068 User Manual | © National Instruments | 13

specific drive finish before removing the device. Refer to the LabVIEW Help for more
information.
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.
For more information, visit ni.com/info and enter the Info Code RT_Paths.
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.
Figure 6. cRIO-9068 Horizontal Mounting

1. Up
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.
14 | ni.com | NI cRIO-9068 User Manual

Tip Before using any of these mounting methods, record the serial number from
the back of the cRIO-9068 so that you can identify the cRIO-9068 in MAX. You
will be unable to read the serial number after you mount the cRIO-9068.
