NECx

NECx
If you get a decode whose protocol name is simply "NECx" that indicates the learned signal is not complete (usually caused by not holding the original remote's button long enough during learning). Enough of the signal is present to accurately determining the device, subdevice and OBC numbers. But not enough is present to determine the exact protocol, which is probably NECx1 or NECx2. This incomplete learn also makes it harder to distinguish NEC from NECx, so a decode of "NECx" might be NEC1 or NEC2 or even Tivo or Pioneer.
