I have a merlin with 3 consoles the first two are QCC the 3rd and last one is a DLC. When I plug the DSS into the DLC console it won't work. But if I plug it in to the other QCC consoles it will work. I'm only using one DSS and I need it plugged into the 3rd console which is the last one and a DLC console. Any ideas why it won't work? Also the DSS has been programmed with the right station numbers.
