    Absolute encoders?

    Can anyone tell me what I have to do to switch a system over to absolute
    encoders, and how do they work?

    Thanks!

    A typical absolute encoder will output a 10 or 12 bit wide bit pattern in either true binary or gray code, if your system only accepts quadrature, then these cannot be used.
    Some systems however use a method of battery back up of the quadrature signal, but again, this is system dependant.
    If you go to a web site like BEI that offer absolute encoders, they should have a detailed explanation.
