Configuring NI 292x Devices
Setting Up the Network (Ethernet Only)
The device communicates with a host computer over gigabit Ethernet. Set up the network to
enable communication with the device.
Note The IP addresses for the host computer and each connected USRP device
must be unique.
Configuring the Host Ethernet Interface with a Static IP Address
The default IP address for the NI 292x is 192.168.10.2.
1. Ensure the host computer uses a static IP address.
You may need to modify the network settings for the local area connection using the
Control Panel on the host computer. Specify the static IP address in the Properties page
for Internet Protocol Version 4 (TCP/IPv4).
2. Configure the host Ethernet interface with a static IP address on the same subnet as the
connected device to enable communication, as shown in the following table.
Table 1. Static IP Addresses
Component Address
Host Ethernet interface static IP address 192.168.10.1
Host Ethernet interface subnet mask 255.255.255.0
Default USRP device IP address 192.168.10.2
Note NI-USRP uses user datagram protocol (UDP) broadcast packets to
locate the device. On some systems, the firewall blocks UDP broadcast packets.
NI recommends that you change or disable the firewall settings to allow
communication with the device.
Changing the IP Address
To change the USRP device IP address, you must know the current address of the device, and
you must configure the network.
1. Verify that your device is powered on and connected to your computer using the gigabit
Ethernet interface.
2. Select Start»All Programs»National Instruments»NI-USRP»NI-USRP
Configuration Utility to open the NI-USRP Configuration Utility.
3. Select the Devices tab of the utility.
Your device should appear in the list on the left side of the tab.
4. In the list, select the device for which you want to change the IP address.
If you have multiple devices, verify that you selected the correct device.
