Ethernet Ports
The Ethernet ports on the smart camera provide a connection between the smart camera and the
development computer or other network devices. The smart camera provides one
10/100/1,000 Mbps Ethernet port. The NI 1732/1752/1754 provide a second 10/100 Mb/s
Ethernet port. Figure shows the Ethernet ports on the smart camera.
Figure 3-2.
NI Smart Camera Ethernet Ports
Port 1 is the primary port and port 2, when available, is the secondary port. The primary port can
be configured to acquire an IP address from a DHCP server. The secondary port can only be
configured for a static IP address.
The primary Ethernet port of the smart camera can connect to a 10, 100, or 1,000 Mbps (1 Gbps)
Ethernet network at either full or half duplex. The secondary port can connect to a 10 or 100
Mbps Ethernet network at either full or half duplex. The smart camera automatically detects the
speed and duplex capabilities of its link partner and configures for the fastest common interface.
The smart camera can also perform auto-crossover, allowing the use of straight or crossover
Ethernet cables, independent of the connection configuration.
When shielded Ethernet cables are being used, ensure that the shields on the Ethernet cables and
the POWER-I/O cable do not contact each other to maintain full Ethernet signal integrity.
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.
