The Ethernet port on the NI CVS-1450 device provides connection
between the NI CVS-1450 device and the development computer, either
directly or through a network port. The NI CVS-1450 device automatically
detects the speed of the connection and configures itself accordingly.
If you are connecting the NI CVS-1450 device to the development
computer through a network port, use a standard Ethernet cable. To connect
the NI CVS-1450 device directly to the development computer, use an
Ethernet crossover cable.
