Hi John - I was typing the above, did not see your reply. See now that "you're the man" for electronic controls for three rail. So based on knowing this board needs to be fed serial data, there is no "cheating" this board to work directly off conventional track fed AC.
Is there some comprehensive source that explains all the different variations of 3R boards that have been used? As stated earlier being a retired Mechanical Engineer I have an insatiable quest for knowledge about how things work.
BTW do you have a junk pile of QSI DCRU boards, or something similar, gutted from Locos you have upgraded? I intend to build my layout around conventional 0-18VAC unless some can convince me otherwise. For an old man like me, staying on the throttle is safer (and less stressful) then trying to keep track of what I am doing with a controller. LOL I really don't want a head on collision between 2 of my brass steam locos. Thank you for your help teaching me what is what - Jim
