This appendix provides instructions for troubleshooting the NI Smart 
Camera.

Possible causes and solutions:

•

The smart camera may not be powered. Verify that there is power to 
the smart camera and that both the smart camera and the development 
computer are properly connected to the network. The POWER LED 
should be lit green and the ACTIVITY/LINK LED should flash green 
when refreshing the list of devices in MAX or Vision Builder AI.

•

The smart camera may have been configured on another network 
subnet and then moved to the current network subnet. Reconfigure 
the smart camera on the current network. Refer to the 

 section of Chapter 7, 

, for more 

information.

•

Another device on the network is using the IP address assigned to the 
smart camera. This can happen when you assign the same static IP to 
two devices, you assign a static IP that is in the range of the IP address 
available for DHCP use on your network, or the DHCP server assigns 
the same IP address to another device. Either remove or reconfigure 
the other device, or reconfigure the smart camera to use a different 
IP address by moving the IP RESET DIP switch to the ON position 
and reapplying power or restarting the smart camera. Refer to the 

 section of Chapter 6, 

, 

for more information.

•

You are experiencing firewall issues. If you are having difficulty 
detecting the system and setting up the NI Smart Camera on your 
network, you must configure the firewall to open the TCP/UDP ports 
used by the smart camera and the host machine. Refer to the 

 section of Chapter 7, 

, for more 

information about TCP/UDP ports.
