In a normal telephone cable the red/green wires crossover within the cable. I tried to use normal telephone extensions to increase the length of the stock X50 cord. The unit simply does not light up, an indication of reverse polarity I suppose.
I then opened the telephone cable to reverse the wires, and it worked like a charm. However I needed more length so I decided to make an adapter that reverses the wires.
I plugged in the stock cable directly to make sure the detector is still working, and it worked fine. Then when I used my adapter (two RJ-11 jacks on each end) the unit didn't light up at all.
I then quickly unplugged it and plugged in the stock cable, to find that my X50 no longer works
How is this possible? Even when I plugged in the wrong polarity into the unit before it just doesn't light up. Why would my adapter that simply reverses the wires (correctly aligning the polarity for the detector) fry it?
Doesn't the X50 have a polarity-detecting power supply? This is what I figured after the first time of mistakingly plugging in the wrong cable.
Is my X50 fried? How did this happen?
