Synchronizing Multiple Devices (Optional)

You can connect two USRP devices so that they share clocks and the Ethernet connection to
the host.
1.

Connect the MIMO cable to the MIMO EXPANSION port of each device.

NI USRP-292X

NI USRP-292X

2.

If you have not already done so, attach antennas to the USRP devices.

If you want to use one USRP device as a receiver and the other as a transmitter, attach
one antenna to the RX 1 TX 1 port of the transmitter, and attach another antenna to the
RX 2 port of the receiver.

The NI-USRP driver ships with some examples that you can use to explore the MIMO
connection, including USRP EX Rx Multiple Synchronized Inputs (MIMO Expansion) and
USRP EX Tx Multiple Synchronized Outputs (MIMO Expansion).

Configuring the Device

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 USRP device 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.
