Troubleshooting the Controller
The cRIO-905x is Not Communicating with the
Network
Use this topic to troubleshoot possible reasons your cRIO-905
x
is not communicating with the
network.
•
Ensure that the USB Device connection between the cRIO-905
x
and the host computer
and the Ethernet connections between the host computer and the router are secure.
•
Configure the IP and other network settings by completing the following steps.
1.
Use a USB-Type-C-to-USB-Type-A cable (included in the kit) to connect the
cRIO-905
x
USB Type-C Device Port with Console Out to a host computer. The USB
driver creates a virtual network interface card and assigns an IP address to the
cRIO-905
x
in the format of 172.22.11.

.
2.
In MAX, expand your system under
Remote Systems

under
Remote Systems
, use the
Troubleshoot Remote System Discovery
utility to walk through
troubleshooting steps.
3.
Select the
Network Settings
tab to configure the IP and other network settings.
4.
(Optional) Use the RJ-45 Ethernet port 0 or port 1 to reconnect the cRIO-905

x
attempts to initiate a DHCP network connection at
power up.
Note
If the cRIO-905
x
cannot obtain an IP address, it connects to the
network with a link-local IP address with the form 169.254.
