I have an older unlenbrock Intellibox IR system with two IRIS hand held controllers. I have attached to it a 6021 and 2 6040's. I am considering a move to a Marklin CS3, but would prefer to not give up my IRIS handhelds (yes, I realize I can use a smart phone as a controller.) (And I would like to keep the 6040's for awhile too.)

I see there is a Marklin interface (60128) for Marklin 6021/6040 etc. to a CS3. Has anyone (1) any knowledge/experience with the 60128 and (2) whether I could connect my Intellbox IR to the CS3 through it, and use my IRIS controllers? (3) And in turn daisy chain the 6040's??
