Encoder no distance/rate?

We would like to use the encoders that came with andymark supershifter gearbox for getting distance in autonomous. However we do not get any feedback. We pulled off a wire and encoder we used last year that was working fine and plugged it into DIO 1 and 2 with no change. We compared last years code with this years code and they are exactly the same. Can someone offer advise?

When you spin the encoder, do the DIO values on the dashboard change? If they don’t, it’s something wrong with the wiring or the encoder itself.

Have you tried the encoder example? I would make sure that works first.
