Hm, what has "differential" to do with "positive" and "negative" ?
Isn't the whole idea with differential that you don't need
to know wheither one or the other line is positive or
negative, as long as one is *more* positive (or *less* negative)
then the othter ?

There is no ground reference in a differatial line, right ?
