Thank you @allObjects for the simple response on dual power.
As there appears that re-editing seems to plague this thread, [me included ;-) ] isn't there a missing 'not' or 'never' in the sentence 'This is the reason that . . . ' and a missing closing ')' found in (#24) ?
@Gordon thank you for the clearing that up. I missed (what the device did\was) the 'LM3671' reference in post #22 and your similar responses to those posed by my suggested clarification. I felt it made more sense to ask explicitly so as to tie in with the documentation that appeared to have missing detail. I'm sure that the topic re-visit will help @trusktr and assist @Thinkscape and others as it has me.
Maybe there is a simple way to show how to connect, which pins to connect to, using the three power input choices in table format, perhaps? Bi-Directional [ J2-3 ] gave me fits until I studied the schematic, as the docs currently state it is an output pin.
