It seems like everything is good. I havent purchased the new plasma unit yet, so hopefully that doesnt cause too much interference was its up and running. Im running the optoisolation board and shielded cables so it should be good. You guys have been a great help, i wouldnt have been able to get this running without you. My partner here that was helping me is on a service trip so i woulda been on my own without the forum. Thanks again.
