I think it unlikely it has to jibe. (Jive is something else.)

I doubt the receiver requires clean or regulated power, and anything
the "converter" puts out is probably fine, but you have to get the
positve and negative correct. Does the receiver say which is supposed
to be which?

It sez polarity doesn't matter. Like for the push-button.

If so, you can use a volt-meter to see which is which on
the converter.

but I don't think you mean converter. A converter nomrally converts
DC current to AC. They often run off a car. But yours you say takes
a 110 volt input. Do you mean an adapter? Is it a little black cube
with prongs that plug into the wall?

Yes.

Or something like a laptop
power cord. 300ma is three times as much as you need to run
something that at most takes 100 ma. So they'll be a little wasted
power. I'm not sure how much. Not all of it because when there is no
power draw, it won't take as much AC as when there is powerdraw, and
when there is 100 ma dra, it won't take as much AC as if it was in
another situation putting out 300ma. You can sort of tell by how warm
the box gets. All of the warmth is waste heat, and all of the warmth
more than a smaller adapter would give is even more of a waste, but
you can use it and keep your eyes open for a smaller 12 volt DC
adapter.

I just don't see how I can wire it if it is designed to both run off
and connect a 12v DC circuit when the object circuit is 120v AC.
