Why Doesn't the USRP Device Appear in the NI-USRP
Configuration Utility?

1.

Check the connection between the USRP device and the computer.

2.

Ensure that the USRP device is connected to a computer with a gigabit-compatible
Ethernet adapter.

3.

Ensure that a static IP address of 

192.168.10.1

 is assigned to the adapter in your

computer.

4.

Allow up to 15 seconds for the device to completely start up.

Why Don't NI-USRP Examples Appear in the NI Example Finder
in LabVIEW?

NI-USRP does not install examples into the NI Example Finder.

Network Troubleshooting

Why Doesn't the Device Respond to a Ping
(ICMP Echo Request)?

The device should reply to an internet control message protocol (ICMP) echo request.
Complete the following steps to ping the device and receive a response.
1.

To ping the device, open a Windows command prompt and enter 

ping 

192.168.10.2

,

where 

192.168.10.2

 is the IP address for your USRP device.

2.

If you do not receive a response, verify that the host network interface card is set to a
static IP address corresponding to the same subnet as the IP address of the corresponding
device.

3.

Verify that the device IP address is set properly.

4.

Repeat step 1.
