John,
I don't have the AIU for my DCS system, how does one control the various function of a device if you use more than one channel? Is there a way to make it look like it's integrated or are they simply separate channels?
Part IV - Accessory and Switch Track Control of The DCS O Gauge Companion 2nd Edition has very detailed discussions of how to best use the AIU to wire a wide variety of switch tracks and accessories, including specific examples of, among others, how to use it to control a Lionel transfer table and Atlas turntable.
This and a whole lot more is all in "The DCS O Gauge Companion 2nd Edition", now available for purchase as an eBook or a printed book from MTH's web store site! Click on the link below to go to MTH's web page for the book!
