All of the DIP switches are in the OFF position when the chassis is shipped from National
Instruments.
SAFE MODE Switch
The position of the SAFE MODE switch determines whether the embedded LabVIEW Real-
Time engine launches at startup. If the switch is in the OFF position, the LabVIEW Real-Time
engine launches. Keep this switch in the OFF position during normal operation. If the switch is
in the ON position at startup, the cRIO-9072/9073/9074 launches only the essential services
required for updating its configuration and installing software. The LabVIEW Real-Time
engine does not launch.
If the software on the controller is corrupted, you must put the controller into safe mode and
reformat the controller drive. You can put the controller into safe mode by powering it up
either with the SAFE MODE switch in the ON position or with no software installed on the
drive. Refer to the
Measurement & Automation Explorer Help
for more information about
installing software on a controller and reformatting the drive on the controller.
CONSOLE OUT Switch
With a serial-port terminal program, you can use the CONSOLE OUT switch to read the IP
address and firmware version of the controller. Use a null-modem cable to connect the serial
port on the chassis to a computer. Push the switch to the ON position. Make sure that the
serial-port terminal program is configured to the following settings:
•
9,600 bits per second
•
Eight data bits
•
No parity
•
One stop bit
•
No flow control
The serial-port terminal program displays the IP address and firmware version of the chassis.
Keep this switch in the OFF position during normal operation.
