Well tonight I was working with EMC2 (http://www.lixuxcnc.org) and getting it all set up on my computer when I realized I had yet another blunder. I ordered a set of 3 cards from Mesa: 7i43-U-4, 7i49, 7i42TA. The computer connects to the 7i43 card with a 25-pin parallel port cable. It's basically a straight-through printer cable all 25 pins go straight through. What I overlooked was my printer cable was male on one end and female on the other. I needed to get a special cable with male connections on both ends. Another F-A-I-L on my part. Back to e-bay tonight! :roll: I didn't even try to find that baby at computer stores. I knew it would be a special item.
Anyway, here are my 3 cards that I got:
It is used specifically with resolvers (which my old TREE has) instead of encoders.
Unfortunately (for my project) we're going on vacation Saturday so I won't be able to really mess with anything until I get back. But due to my blunders, I didn't have all of the pieces I needed anyway, so in effect the vacation will help me from going nuts as I wait for my special cables to arrive.
