 For maximum throughput, one ethernet interface per USRP2 is recommended,
 although multiple devices may be connected via a gigabit ethernet switch.

+MIMO cable configuration
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Using the MIMO cable, two USRP devices can be grouped together in a multi-device configuration.
+Only one device in the configuration can be attached to the ethernet.
+This device will be referred to as the master, and the other device, the slave.
+
+* The master provides reference clock and time synchronization to the slave.
+* All data passing between the host and the slave is router over the MIMO cable.
+* Both master and slave must have different IPv4 addresses but in the same subnet.
+* The master and slave may be used individually or in a multi-device configuration.
