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.

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.
NI-USRP Examples and Lessons
NI-USRP includes several examples and lessons for LabVIEW, LabVIEW NXG, and
LabVIEW Communications System Design Suite. They can be used individually or as
components of other applications.
NI-USRP examples and lessons are available in the following locations.
