Troubleshooting the NI 9149
The NI 9149 is Not Communicating with the Network
• Ensure that the USB connections between the NI 9149 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 A-to-B cable to connect the NI 9149 USB device port to a host
computer. The USB driver creates a virtual network interface card and assigns an IP
address to the NI 9149 in the format of 172.22.11.x.
2. In MAX, expand your system under Remote Systems.
3. Select the Network Settings tab to configure the IP and other network settings.
4. (Optional) Use the RJ-45 Ethernet port 1 to reconnect the NI 9149 to the host
computer. The NI 9149 attempts to initiate a DHCP network connection at powerup.
Note If the NI 9149 cannot obtain an IP address, it connects to the
network with a link-local IP address with the form 169.254.x.x. The host
computer communicates with the NI 9149 over a standard Ethernet
connection.
• Ensure that you have the correct version of NI-RIO Device Drivers installed on the host
computer. Visit ni.com/info and enter the Info Code swsupport for the minimum
supported versions of LabVIEW and NI-RIO Device Drivers.
Tip If you have recently upgraded LabVIEW, you must reinstall NI-RIO
Device Drivers.
• Ensure that the NI USBLAN adapter is recognized in the Device Manager. On
Windows 7, select Start»Control Panel»Device Manager»Network adapters»National
Instruments»USBLAN adapter. If the USBLAN adapter is not recognized, you must
reinstall NI-RIO Device Drivers.
• Temporarily disable any network firewalls or other security software.
