Thank you. I was slogging my way through that long thread but not finding the answer I was seeking.

I forgot to ask: is the above (bolded) documented somewhere? Before posting here I pulled up the on-line LabVIEW help for the encoder vi but all it said was:

Decoding Type specifies the type of decoding used to decode the quadrature signal. Decoding Type supports three types of decoding for quadrature encoders: 1x, 2x, and 4x.

... which wasn't very informative.
Is there somewhere else that a LabVIEW beginner should be looking for this kind of information?
