It depends on which QSI Magnum decoder you are talking about. They built two different versions.. QSI was a key partner in the development of the sandard for the socket and they sold a version where all the pins were connected per the standard they helped develop. QSI was also at the time very involved with Lewis Polk at Aristocraft and tested out a large number of their locomotives. QSI found that several Aristocraft locomotives had unpredicted connections to socket pin #s J1:5, J1:7, J2:4, J2:5, J2:6, J2:7, J2:8, and J2:9, Even Louis did not know that this was the case and indicated that no locomotive in the future would have these strage connections.
To protect their decoder designed for Aristocraft Locomotives, QSI built a special decoder for Aristocraft locomotives where the smoke, chuff input and functions outputs were not connected.
You can use these decoders in the Dash-9 and neither the locomotive or the decoder will be damaged. However you will not be able to control these extra functions without extra work.
Hope this helps.
