DCS Commander Issue.

My son and I have been using an MTH DCS Commander to run a floor layout and it works great with a Rail King Blue Comment set, Rugged Rails. This set is only a couple of years old, but we also have a Rail King Daylight set from the 2002 catalog that has 2.O in it that will not respond to it at all.

The RK Daylight ran with my DCS system and it responds to the Z750 because when I performed the 1-whistle and 5-Bell reset to factory engine one I get the two toots that indicates a return to engine One address.

Everything works just great with the Z750, but the Commander is dead to it, though as stated above it talks to the Blue Comment.

I know the Daylight is 2.O because I used it many times with my DCS system and I doubt if it would of responded to the reset if the system was no longer working.

Could it be possible that the Daylight has a version of DCS that dose not recognize the Commander system? The directions talks about pre 1997 systems not working with it but I don't think any of them are DCS 2.0.
Or is there another reset I should be using?


I know that this topic should be on the DCS page but we have been talking so much about the Commander over the past week or two here I thought the problem might be fun to kick around.

Thank you for any input, even if your answer makes me feel like a dummy.
