Joe...Check within these web sites for the encoder manuals.
Or just Google "encoders" on the web.
There is much info to examin....John

ps....all encoders produce a square wave directly proportional to the input voltage. So if 5 vdc is the source the output will be 5 volts. You see, an encoder does nothing but count revolutions. And is capable of direction selection as the encoder can output a negative or positve square wave depending on the shaft rotation.

Resolvers output a sign wave that also can produce voltage either negative or positive, but are analog, not digital.
I hope the web sites I have provided can be more specific and answer any questions you may have......John

gfretwell.... I am not familiar with your application. I was referring to electric motors and equipment. I am not literate in the inner workings of computers....John
