Smaart and all its functions can ONLY be handled by your RM, so your microphone needs to be plugged into RM. The CS controls the RM, but has no firewire connection to the computer serving Smaart. Many people are missing Smaart and especially RTA on CS very much, but it doesn't look like it will ever be added. The only solution is to place another RM16AI next to the CS and set up an AVB network. The RM mixers get cascaded, the CS handles them as one single mixer. This brings firewire and Smaart back to FOH...
