LED Indicators and DIP Switches
Device Initialization
While the NI Smart Camera initializes, the POWER LED lights solid green and the STATUS,
IMG ACQ, PASS, and FAIL LEDs exhibit a scrolling pattern. When the smart camera finishes
initializing, the STATUS LED lights solid green. If the system does not initialize within the
expected period of time, the STATUS LED flashes a status code. Refer to the
STATUS LED
section for information about the status codes.
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, it
connects to the network with a link-local IP address with the form 169.254.x.x. 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 7-1.
