Hi We are doing a project in that project there are three 8 button neo keypads,1 pascal controller and one (Bus coupler). The solution has 3 rooms like hall 1,hall 2,hall 3 these three halls are separated by the movable partition. My client wants when three partitions are closed the 3 neo keypads should work individually to that room only. But if he opens any one partition say the partition b/w hall 1 and hall 2 is opened then the keypads in the both rooms should work same that means the program on the keypads should change. i don't have any idea with the coupler and pascal controller can i do that.
