Well, after some trial and error, I've come up with the following diagram for my Ross Double Slip. I connected everything on the bench and it works, so I made this diagram so I can duplicate it when I install it this weekend. If you think about how this switch works, it actually makes sense.
However, unless you actually have this switch to look at, the diagram will be hard to follow. The big difference with this switch from a standard switch is each side has 4 points, not two. That is 8 points total. The result is a train does not derail going into the switch, no matter which leg it enters on or how the DZ-2500s are set. It derails as it exits if not set correctly.
That means the #2 DZ-2500 on the left in the diagram gets its non-derail and alternating power wires to the leads from the trackage on the right side, and the opposite for the right #1 DZ-2500. To make it work and keep my wiring colors consistent, the green and yellow wires from the DZ-2500 are connected to the opposite colors on the breakout board.
The wiring to the lead rails is from the switch diagram from Ross (as shown in above posts), so no change there from earlier discussions. I had to play with it a while to understand how that setup worked.
The issue was the non-derailing function. I almost gave up trying to make it work because there really are two non-derailing actions when a train goes through the switch; once when it enters and once when it exists. I was worried that when it exited the non-derailing function would now derail the train. Well, it turns out with this wiring setup the non-derailing function on exit does not change the DZ-2500s position, no mater how the train exits.
You can also arrange the DZ-2502 controllers so that the LEDs line up to help show switch position.
I'll have it installed soon to see if I got it right. In the meantime, go ahead and stare at the diagram for a few hours and it will start to make sense.
