NI CVS-1459RT User Manual
Ethernet Port
The Ethernet port on the NI CVS-1459RT provides a connection between the NI CVS-1459RT
and the development computer, either directly or through a network. The NI CVS-1459RT
automatically detects the speed of the connection and configures itself accordingly.
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 the necessary requirements. While CAT 5 cables may appear to work at 1,000 Mbps, CAT
5 cables can cause bit errors, resulting in degraded or unreliable network performance.
Figure 3-4 shows the pin locations for the Ethernet port.
