Ok... First off, I admit I have never been strong in the wiring department... I know it is simple... two sets of wires on a control panel.  A common Daisey chained wire and the switch line which runs to the breakout board (I am using a KE72T with iox36)  My question is...  What do I connect my common wire to?  Is it the ground screw down on the iox36?
If it is, any ideas as to why I receive an keyboard failure notice when I do?  I actually ran two commons to help narrow down wiring issues.
THanks!!!
