Hello list, I would like to announce support for the MIMO cable with UHD. The support is experimental, so its not in the mainline yet, and is only available for USRP2 at the moment. The source for the FPGA code has not yet been pushed but you can get the pre-built images here: http://www.ettus.com/downloads/uhd_images/experimental/UHD-mimo-cable-support/ The supporting host code is available on the packet_router branch of the uhd repo: http://code.ettus.com/redmine/ettus/projects/uhd/repository/show?rev=packet_router Here is an excerpt from the docs on the MIMO cable in UHD: > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > 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 routed 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. I hope that explains it. Feedback is welcome! Thanks, -Josh

Is the FPGA code for mimo cable support available? Is that also on the packet_router branch (you mention only the host code below)? If not, how can I access it? Also, are there example host programs that exercise this code? Thanks, Arun On 12/13/2010 7:34 PM, Josh Blum wrote: > Hello list, > > I would like to announce support for the MIMO cable with UHD.
