Is there a way to take over a M9484 without buying a 135 ohm converter? How does this thing work inside? Does it send out a voltage/current? Can I successfully use two outputs for the B & W? Voltage or current? If my controller is trying to supply the current would that conflict? I am asking because I already have a controller there and this would be a 'no charge' promo. Seems like there's less than 2 volts on the terminals.
