Experimenting with the Legacy controller to switch command routes. It would seem from my experiments, that more turnouts in a route increased the probability that a turnout will not switch. This maybe implies a voltage drop issue with say four switch machines all trying to switch at the same time. I may do some experiments with this idea. Currently, I am powering the layout with two CW-80s ganged together, putting out maximum voltage, with the engine running while I hit the route. The turnouts take power from the track.
I also notice that if the route button is held down, the controller will send a command repeatedly in successive pulses. I have even seen a route behave this way, with the button held the entire time: pulse-1: switch one fires, the others buzz. Pulse-2, another switch fires, the others buzz, etc until all four turnouts have switched, and the button is released.
Sending a command to an individual turnout: they are all switching reliably as individuals.
The open circuit voltage output of the CW-80 is 17.9v.
