Single Ethernet Interface—One Device
You can configure multiple devices using a single host Ethernet interface when the devices are
connected to each other using a MIMO cable.
1.
Assign each device a separate IP address in the subnet of the host Ethernet interface, as
shown in the following table.
Table 3. Single Host Ethernet Interface—MIMO Configuration
Device
Host IP Address
Host Subnet Mask
Device IP Address
USRP Device 0
192.168.10.1
255.255.255.0
192.168.10.2
USRP Device 1
192.168.10.1
255.255.255.0
192.168.10.3
2.
Connect Device 0 to the Ethernet interface and connect Device 1 to Device 0 using a
MIMO cable.
Single Ethernet Interface—Multiple Devices Connected to an Unmanaged
Switch
You can connect multiple 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 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.

USRP Device 0
192.168.10.1
255.255.255.0

USRP Device 1
192.168.10.1
255.255.255.0
192.168.10.3
Programming the Device
You can use the NI-USRP instrument driver to create communications applications for the
USRP device.
NI-USRP Instrument Driver
The NI-USRP instrument driver features a set of functions and properties that exercise the
capabilities of the USRP device, including configuration, control, and other device-specific
functions.
Related Information
Refer to the NI-USRP Manual for information about using the instrument driver in your
applications.
