Greetings,
I am not an electronics expert by any means, just a rank beginner. But
in the last year I have been using encoders for some custom
applications and have learned quite a bit about them. Nearly all this
knowledge came from US Digital. Their website is USDigital .com. I
think. Anyway, they sell a device for connecting encoders to long wire
runs. The prices are from $11 to $34 for these cable drivers. Here's
the link: http://www.usdigital.com/products/ea/ . They will answer
your questions and can tell you if their device will work with your
encoder. They were able to help me connect a twenty year old encoder
to one of their displays. Anyway, I'm just a satisfied customer. No
connection to them other than that.
