How do i connect the pins on a DC power jack? Im upgrading from using a battery, and the power jack i have has 3 pins on it. The power supply im plugging into it has a positive center and negative outside. On the jack, the inside appears to have a pin, but the outside appears to be connected to 2 pins. Do i just leave one of these pins floating, or connect both to a single gnd line. Thanks.
