search for curtis 1214 software on this site and go to the other thread. It talks at length about how to talk to your controller. It involves making a cable with mollex and serial cables. the cable is the easy part. The part that is confusing me is the required rs232 ttl max232 adapter. Evidently it also requires an additional sn741s04 component to invert the signal. This is a few steps above my ability and I am working to find a non user fabricated adapter that will plug in to my cable. Look at the other thread and good luck. Ed
