LEDs and DIP Switches

The initialization scrolling pattern will last longer than usual if the smart camera is configured 
to acquire an IP address from a DHCP server but no DHCP server is available on the network. 
When acquiring an IP address from a DHCP server, the smart camera waits up to 60 seconds to 
acquire an IP address. If the smart camera does not receive an IP address within 60 seconds, the 
device automatically restarts and tries again. The smart camera attempts to acquire an IP address 
from a DHCP server three times. If after the third time the smart camera has not been assigned 
an IP address, the smart camera reverts to the unconfigured state and the IP address resets to 

0.0.0.0

. The STATUS LED flashes to indicate that the smart camera is in an unconfigured 

state.

POWER LED

The POWER LED indicates whether the power supplied to the camera is adequate. The POWER 
LED is green while the camera is properly powered on. When no power is being supplied to the 
NI Smart Camera, the POWER

 

LED is unlit. When power is first applied to the smart camera, 

the POWER

 

LED flashes red for one second while internal systems power up. If the POWER 

LED stays red for longer than one second, it indicates that the voltage is out of range.

STATUS LED

The STATUS LED is green during normal operation. The NI Smart Camera indicates specific 
conditions by flashing the STATUS LED, as shown in Table 6-1.

Table 6-1.

Green

The smart camera IP address or software is unconfigured. The 
smart camera ships from the factory unconfigured. The smart 
camera also enters the unconfigured state if it is configured for 
DHCP and no DHCP server is available. Use MAX or Vision 
Builder AI to configure the smart camera. Refer to 

Getting 

Started with the NI 17xx Smart Camera

 for information about 

configuring the smart camera.

2 Flashes

Green

The smart camera detects an error in the software 
configuration. The camera has automatically started up into 
safe mode, regardless of the SAFE MODE DIP switch position. 
This usually occurs when an attempt to upgrade the software is 
interrupted or if system files are deleted from the smart camera. 
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.
