Confirming Network Connection
1. Select Start»All Programs»National Instruments»NI-USRP»NI-USRP
Configuration Utility to open the NI-USRP Configuration Utility.
2. Select the Devices tab of the utility.
Your device should appear in the list on the left side of the tab.
Note If your device is not listed, verify that your device is powered on and
correctly connected, then click the Refresh Devices List button to scan for
USRP devices.
Configuring Multiple Devices with Ethernet
You can connect multiple devices in the following ways:
• Multiple Ethernet interfaces—One device for each interface
• Single Ethernet interface—One device connected to the interface, with additional devices
connected using an optional MIMO cable
• Single Ethernet interface—Multiple devices connected to an unmanaged switch
Tip Sharing a single gigabit Ethernet interface among devices may reduce overall
signal throughput. For maximum signal throughput, NI recommends that you
connect no more than one device per Ethernet interface.
Multiple Ethernet Interfaces
To configure multiple devices connected to separate gigabit Ethernet interfaces, assign
each Ethernet interface a separate subnet, and assign the corresponding device an address
in that subnet, as shown in the following table.
