Hi, it sounds like we are trying to do the same thing and I've run up against exactly the same problem (data communication down the return opto). I know this thread is a bit old and you've probably forgotten about it entirely but did you make any progress or find a work-around? At the moment all I can think of is a micro-crontroller board to mimic the serial data but that my last resort. Any help would be incredible, thanks.
