NI 17xx Smart Camera User Manual B-2 ni.com
• The cable you are using may be inappropriate for the speed of your
network, causing network communication dropout. While 1,000 Mbps
communication over short cables lengths can be achieved with the
CAT5 cable commonly used for 10 and 100 Mbps, CAT5e and CAT6
cables are more reliable and recommended for 1,000 Mbps links. The
smart camera has the ability to perform auto-crossover, allowing the
use of straight or crossover Ethernet cables, independent of the
connection configuration.
The NI Smart Camera Restarts Unexpectedly
Possible causes and solutions:
• The smart camera is configured to acquire an IP address from a DHCP
server, but no DHCP server is available on the network. When the
smart camera is configured to acquire an IP address from a DHCP
server, it waits for up to 60 seconds for the IP address to be acquired
successfully. If the smart camera does not receive an IP address within
60 seconds, it restarts and attempts to acquire an IP address again.
After three unsuccessful attempts to acquire an IP address from a
DHCP server, the smart camera restarts and enters an unconfigured
state. In the unconfigured state, the smart camera has an IP address of
0.0.0.0 and only limited software loads.
In the unconfigured state, the smart camera has network connectivity.
If the smart camera is on the same subnet as the host computer, then
refreshing the list of remote devices in MAX or Vision Builder AI will
cause the smart camera to appear with an IP address of
0.0.0.0. Use
MAX or Vision Builder AI to reconfigure the smart camera IP address,
then restart the smart camera.
Refer to Getting Started with the NI 17xx Smart Camera for more
information about assigning an IP address to the smart camera.
• The smart camera has detected an error in the software configuration
and automatically restarted into safe mode, independent of the state of
the SAFE MODE DIP switch. This usually occurs when an attempt to
upgrade the software is interrupted or if system files are deleted from
the smart camera by the user. Reinstall software on the smart camera.
Refer to Getting Started with the NI 17xx Smart Camera for
information about installing software on the smart camera.
• The smart camera experienced two consecutive software exceptions.
The smart camera automatically restarts after an exception. After the
second exception, the smart camera remains in the exception state,
alerting you to resolve the problem. To correct this issue, reinstall
software on the smart camera. Refer to Getting Started with the
