turbgine,
Absolutely you can run conventional using your DCS hand held remote control thru the TIU TR mode on your hand held remote control. I do suggest you get a copy of Barry's DCS O Gauge Companion book and follow his well written directions for setting it up. Also I would suggest you purchase the side receiver for your Z4K it opens up another Conventional running opportunity via the TR Z4K mode. Also follow Barry's
wiring recommendations for DCS. You should also pick up a copy of the OGR Video Guide to DCS, Rich does a great job on the visual instructions of all this from the very beginning also, a better visual education on DCS you will never see.
