Aha. That feature is not implemented, but it is not far away. For the
time being, the devices will need a shared PPS to sync. I believe that
you can configure one of the USRP2 to lock reference over the mimo
cable, but you will have to modify the python code a bit.

When the MIMO cable support is completed, you will plug one device into
the ethernet (this will be the master). And the slave device will lock
its reference and sync its time over the MIMO cable. Both devices will
communicate to the host via ethernet.
