Issue Details

I have a USRP RIO and a x8 MXI Card. Is there any way to connect the two together?


Not directly. The CPS-8910 can bridge this gap using it's x8 MXI upstream port and x4 MXI downstream ports. The alternative is to purchase a x4 MXI card.

Additional Information

The CPS-8910 is a MXI-Express Switch that has a x8 MXI connector to a controller and several x4 MXI connectors to connect to a USRP.
