what are the "black dots" on data sheet diagrams adjacant to 2 of the four pins. I have a Triad VSPP28-2000 transformer and on the diagram, by two of the four pins there is a black dot? i've been trying to find out what they mean, if anything? thanks, I'm just getting back into a hobbie that stopped 20 years ago and picking up where i left off?
