Ok I see all the posts on wireing this board but I don't see how to wire the switches with Atlas track and how you wire the switch machines. It would be great if someone would do a video of some of this stuff. or talked me through the process of powering the frogs of an Atlas O-72 Switch With This board. Any Help would be great. Thanks Scot

Scot here is a link to eric's siegel's site. He has a how to video on there hooking up atlas switches. http://www.ericstrains.com/ Jeff
Atlas power routing wiring diagram with the 6924 relay board. Click on the underlined phrase to link.
Requires:
(7) or (8) wires from the relay board to the switch location.
(3) or (5) additional wires to the relay board for power.
You are using the:
Two short rail pieces off the frog as sensor input rails for automatic non-derail feature. A wire from each isolated rail piece attaches to the board. (2) wires.
One of two wires attached to one of the two isolated pieces of rail off the frog.
Two dead rail pieces in the middle of the switch are powered, logically, through the relay board, to inhibit engine stalling in the middle of the switch. (2) wires.
Wire attached to one of the two dead rail pieces, center of switch.
Common. To the switch motor center terminal. (1) wire.
Out A (straight) To the switch motor outside terminal (1) wire.
OUt B ( diverge) To the switch motor outside terminal (1) wire.
The relay board also requires power. (2) wires, 6 to 18 volts AC or DC. Lower right on the board.
Switch power in, (SW PWR IN) (1) wire. Through the board this will throw the switch either straight or diverge.
Here's another thread that may add some more info for you about the 6924's. I had similar questions. Unfortunately I've not progressed far enough on my layout to get to the wiring of any of them yet.
I just want to thank guys for your input on this matter. Mike CT Do you have any photos of the bottom of an Atlas switch with the jumpers cut and ready to install ? And Any photos of a switch machine ready to install ? I just can't get all of this wireing stuff to sink in and just think I was a member of the I.B.E.W. Local 701 and I used to wire fire alarms in the Chicago area. I guess they say I had a couple of strokes wile I was waiting for the kidney transplant. Well any way thank you all for the information you guys gave. Scot
