The first thing that I would do is connect a known working string (one from one of the Zeus controllers) to the SSC V4 and see if you can configure it that way. If so, then you know that the problem is with the new nodes. If not, then confirm the string is still working with the Zeus. If it still does, then you know that the issue is with the SSC. If the problem is with the SSC, then post back and we can try and debug it further. If the problem is with the nodes, as twooly said, check the wiring on the nodes. Make sure that not only is the polarity correct, make sure that your data is connected to the node input and not the output. If you connect to the wrong end of the string, it will not light. The power can be connected to either end, as long as the polarity is correct but the data line must be connected to the correct end (input) or the nodes will not see the signal and will not respond.
