Hi all Just wonder, is there any way to diagnose the DSK subsystem without connection to the control cabinet (x9 connector disconnected)? because in case of the problems like communication fault the ZID only shows the "heidelberg CP TRONIC". So what I do to find out where the problem is, move the DSK to another working machine. If it's working then the problem is in somewhere else. Is there any other way to get the status of the DSK by itself? (For example, keep pressing the numeric pad key while power on or something...) I think this will important for many people out there Thanks.
