If the encoders are plain digital, then this is easy. Any one of the
low-cost
PC DRO kits should work. If the encoder is analog, with interpolation
in the
readout box, then it is MUCH harder.

Heidenhain's web site is http://www.heidenhain.com/

Their manuals on encoders give extremely detailed descriptions of the
signals and connections to the encoders.
