Re: Wiring help needed

Tim,

You got the basic idea, the PM42 would be wired after the Zephyr, and then out to the layout.  The PM42 provides short circuit protection, but also gives you the ability to divide the layout into four separate blocks, each with its own short-circuit protection.  So if a train derails in one of the blocks, trains keep running in the other three.  The block with the short circuit will automatically reset itself once the short is removed.

One note, if you do decide to buy a PM42, also buy the PM42 breakout board offered by Accu-Lites.  It make installation very, very easy.  If not, you are looking a using a 44-pin connector which you need to wire yourself.
