Jeremy/all,
? The term "daisy chaining" is tricky and you need to be careful how you use it ...
? There are two "outputs" on the PSX/PSXX series.? One is a 'daisy chaining' and is only
there for the convenience of wiring your layout.? It is on the same end of the board as
the input.? The other output is the 'true' output of the board and is on the other end of
the board.? It is best, when wiring your layout, to avoid ever having any -wiring- from the
output of any PSX/PSXX board to another PSX/PSXX board.
? Please note/pay attention to that I'm not talking about the track, just the wiring.??
However, when using any DCC track circuit breaker - it is best practice to double
gap the track at the breaker boundaries.? And, if the breaker is also a reverser?
that is -necessary- for proper operation of the breaker.? Reversing sections
need to be isolated from the rest of the layout.? And, in general, they need to be
"longer than the longest train that will ever be run thru them" - because if the
train (or two trains) crosses both boundaries at the same time it will "confuse"
the reverser and will be seen as a short instead of the need to reverse.
? Here is how reversers work.? When they see a short they immediately reverse
the polarity of the track they control (the output) and check to see if the short is
cleared.? If it is not they go into "Short mode" - if the short is cleared they leave
it reversed and the train will continue to run.
? And additional 'trouble' is if you have two reversing sections against each other.
When a train crosses that gap it can result in a hard stop of the train - or at
least a noticeable hesitation.? Even if the train is using a Keep Alive - although?
keep alives will usually get the train across this gap - but it may hesitate for
other wheelsets than just the first one and sort of 'stutter across the gaps' (if
you are using all metal wheelsets which is recommended).?
? I hope this clears up some of the confusion about what you are doing/what you are
reading in the manuals or here on the web.
