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 Host 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.
Table 3. Multiple Host Ethernet Interface Configuration
Device
Host IP Address
Host Subnet Mask
Device IP Address
NI USRP Device 0
192.168.10.1
255.255.255.0
192.168.10.2
NI USRP Device 1
192.168.11.1
255.255.255.0
192.168.11.2
Single Host Ethernet Interface—MIMO
You can configure multiple devices using a single host Ethernet interface when the devices are
connected to each other using a MIMO cable. Assign each device a separate IP address in the
subnet of the host Ethernet interface, as shown in the following table. Connect Device 0 to the
Ethernet interface and connect Device 1 to Device 0 using a MIMO cable.

Single Host Ethernet Interface—Unmanaged Switch
You can connect multiple NI USRP devices to a host computer through an unmanaged gigabit
Ethernet switch that allows a single gigabit Ethernet adapter on the computer to interface with
multiple NI USRP devices connected to the switch. Assign the host Ethernet interface a
subnet, and assign each device an address in that subnet, as shown in the following table.
