Encoders

["Robert Henning" <henning@cars.uchicago.edu>]

I am trying to integrate some Renishaw encoders into EPICS and I am
trying to find a simple solution.  I don't have a lot of experience with
encoders so any comments or suggestions would be welcome.  At this point
I only want to use the encoders to verify my stepper motor position and
I was hoping for a simple RS232 interface.  I know this has been done
with other brands of encoders but I have not seen anything with the
Renishaw brand.  The encoders have "Differential signals in quadrature
to RS422 - output via line drivers".  

I know I could use the OMS58-4 card but I think that is more then I
need.  I just want to be able to read in the information to EPICS for
now.

Thanks in advance,
