I know that the pci-6711 is supported since nidaq 6.5 and that since that version the at-mio-16x is no longer supported. Thus, there is no way to get them to install in the same computer. Either you must install them in different computers, or you should get a new board which performs the same operations of the mio-16x. There is a huge variety of E series boards which perform operations much better than that legacy board. Maybe you can get it to exchange with your Sales Rep.
Hope this information is useful.
