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, 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.
