Assuming your XR10 pro’s port is working, sounds like you got a defective unit. I would try turning the plug around and plugging in just to verify that the wires (pins) haven’t been reversed. I once bought a servo that wires where shortened and i guess when they re-pinned it the negative and neutral wires were reversed. You can also try putting power directly to the OTA programmer to see if it powers up. Hopefully you can return or request refund.
