Hi, I’m currently in the process of planning a DC layout, I have tested the HM6000 and HM6010 and all seems to work as advertised, I’ve even managed to get two aspect signals working via a Blocksignaling PP15 points position indicator from the same port as the point motor and also two sets of synchronised points from the same port. As I need to operate approximately 18 sets of points, my question is…. Is the limit of three HM6010 units per HM6000, based upon paired units (provisioned ) or connected. it would be helpful to have 4 units paired and to connect and disconnect as required up-to the Apps limit. Hope someone can assist, Thanks
