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.
Table 4. Single Host Ethernet Interface—Unmanaged Switch 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
Programming the NI 292x
You can use the NI-USRP instrument driver to create communications applications for the
NI 292x.
NI-USRP Instrument Driver
NI-USRP features a set of VIs and properties that exercise the functionality of the NI 292x,
including configuration, control, and other device-specific functions. Refer to the
NI-USRP Help for information about using the instrument driver in your applications.
NI-USRP Examples
The instrument driver examples are instructional tools that demonstrate some of the
functionality of the NI 292x. You can use these examples separately or integrate them into
your systems. NI-USRP includes examples for getting started and other SDR functionality.
You can access the NI-USRP examples from the following locations:
