Ethernet Port
The Ethernet port on the NI CVS-1459 provides a connection between the NI CVS-1459 and a
network. The NI CVS-1459 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 1,000 Mbps (Gigabit)
Ethernet performance. CAT 5e and CAT 6 Ethernet 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.
