Here is a photo of the power supply that cannot be used with another source of power unless you have a data only cable between it and the other source of power. The connector on it connects to a command bus port just like the command bus cables. If you did not get a starter pack then you probably do not have one since the do not come with a X10, WE, XD or controller only on X4, X2, X3 or XS. The latter are the only ones that would need t if they are not in a collective with other controllers that have power.
