KOP Encoders.

So would I use the other encoder type that isn't index encoder in robot builder?

I'm not familiar with the particular options in robot builder. But if you are wiring up channels A and B to the digital side car, then you're using the encoder as a quadrature encoder. IF there's an option that says quadrature, pick that one.

For info on what quadrature is, check out these links:

Otherwise if you could provide a list of named options, or a screenshot, I could help direct you better.
