NI 17xx Smart Camera User Manual 7-2 ni.com
Note A CAT 5e or CAT 6 1000Base-T Ethernet cable is required to achieve maximum
1,000 Mbps (Gigabit) Ethernet performance. CAT 5e and CAT 6 Ethernet cables adhere to
higher electrical standards required for Gigabit Ethernet communication. CAT 5 cables are
not guaranteed to meet necessary electrical requirements. While CAT 5 cables may appear
to work in some installations at 1,000 Mbps, CAT 5 cables are likely to cause increased bit
errors resulting in degraded or unreliable network performance.
Ethernet LEDs
Figure 7-2 shows the Ethernet LEDs on the NI Smart Camera.
Figure 7-2. 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 7-1.
