RJ-45 Gigabit Ethernet Ports
The cRIO-9081 has two tri-speed RJ-45 Gigabit Ethernet ports. By default, both Ethernet ports
are enabled and configured to obtain an IP address automatically. The Ethernet ports can be
configured in MAX.
The following table shows the pinout for the RJ-45 Gigabit Ethernet ports.

Note
Both Ethernet ports perform automatic crossover configuration so you do not
need to use a crossover cable to connect to a host computer.
The following NI Ethernet cables are available for the cRIO-9081.
