Yes seriously; can you name one current C4 device that is controlled via serial other than an LU/Leaf VMS?
I would say using the RTI remotes to control the C4 system and I wouldn't go this route. I had to do this with URC when elan didn't have remotes and we did the control with IR. It all worked out but what a huge cluster.
