For my FasTrack layout, I prewired my two OTC’s in daisy-chain fashion, according to the Lionel manual. My intention was to use the first OTC for operating tracks and the second for uncoupling. I coded the first to “98” to reflect its use for operating tracks and coded the first wired position as “1”. After I was able to get it operating, I wired up the uncoupling track and coded the second OTC to “99” to reflect its use for uncoupling. I also coded its first wired position as “1”.
Unfortunately, the second OTC doesn’t uncouple; instead it operates as another operating track controller, responding to position “2”.
Should I have disconnected the second OTC from the daisy-chain before I programmed the first OTC in order to avoid inadvertently programming both?
