NI Smart Camera Ethernet LEDs
ACTIVITY/LINK LED
The ACTIVITY/LINK LED indicates whether a link is established between the NI Smart
Camera and the device connected at the other end of the Ethernet cable. The LED is unlit when
no cable is connected or if the smart camera or the device connected at the other end of the cable
are powered down. The LED is solid green when a link is established, but there is no traffic
activity on the link. The LED will flash green when there is traffic activity on the link. If the
smart camera is connected to a corporate network, traffic that is not related to the smart camera
traffic will often be present on the link. In dedicated links between a computer and the smart
camera, typically the only traffic on the link will be the communication between the computer
and the smart camera.
SPEED LED
The SPEED LED indicates the speed of the negotiated link. The NI Smart Camera supports
10 Mbps, 100 Mbps, and 1,000 Mbps (1 Gbps) links, and will automatically select the highest
speed shared by the smart camera and the device it is connected to. The SPEED LED follows
the behavior specified in Table 3-3.
