They are fully floating. You can tie the + side of one of the 5V outputs to ground and that automatically makes the other terminal -5V. It's called 'stacking" with the center node tied to ground.t06afre: I have 2 adaptors as in adaptors you plug into the wall. Its output is +5V DC and I believe one is ground and the other is +5. I was wondering how to change one to -5V DC
Yes that is corret. Just connect what you call GND on adaptor 1, to +5 on adaptor 2. This will be the new GND in your system. The ground on adaptor 2 will become -5 voltSo ok, let me clarify this for myself: Each adaptor I have has 2 outputs: one is +5V and other is GND (ground). So what you're saying is:
Adaptor 1: Keep +5V, and keep GND
Adaptor 2: Connect +5V to some other ground, and GND will become -5V??
