RCSP recognizes when the decoder is hooked up. It can see it, but it still does not register the hits. I have a friend that has tested the decoder and says that it works. So we have plans to mock up my scoring system next to his and see what is the weak link. Maybe its my homemade loop and coupling, but if that were the case I wouldnt think that the decoder would beep when a transponder hits the loop. Hopefully its the serial cable and I can replace it and go on with life.

Thanks for at least attempting to help guys. I really appreciate it.
