NI roboRIO User Manual
Connecting the NI roboRIO to a Network
Connect the NI roboRIO to an Ethernet network using the Ethernet port. Use a standard
Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable to connect the NI roboRIO
to an Ethernet hub, router, or directly to a computer.
Caution
To prevent data loss and to maintain the integrity of your Ethernet
installation, do
not
use a cable longer than 30 m.
The first time you power up the chassis, it attempts to initiate a DHCP network connection. If
the chassis is unable to initiate a DHCP connection, it connects to the network with a link-local
IP address with the form
169.254.x.x
.
Preparing the NI roboRIO for Competition
For information about configuring the controller for competitive use, refer to the Tutorials tab
in the Getting Started window of LabVIEW for FRC.
User Power
Table 1 describes the user voltage rails for powering external sensors and peripherals. The rails
are independent from the power supplies of internal systems, such as the processor and memory.
