In any case, I can't find where to change the samples/rev. Any ideas?
I believe it defaults to 4096 bit but can be changed through the digital interface.

We have tried this encoder on a shooter wheel and it can swamp the cRio pretty quickly. IMHO this encoder would probably best shine in a lower speed continuously rotating system or as a positional sensor.
