Hi Peter,
You have to be really careful with TMCC/Legacy in a show environment.
As TMCC communicates by radio other layouts can pick up the signals. So if an layout has TMCC equipped engines running conventionally they can pick up the TMCC signal and think they are on a command layout. Then they won't run conventionally.
Rule number one is to have list of all Powermaster and Locomotive address numbers and to make sure each layout is assigned a group of numbers. So you don't get two engines with the same address number.
Rule number two is that as soon as you have a command base switched on in the building (at least of the size we have for our annual club shows here in the UK) you can't have a conventional layout running TMCC/Legacy engines.
Also never use the number 1 id address. As that is the default address for new engines.
You do not want two engines on different layouts with the same id address!
Oh and if you push the halt button you stop every TMCC layout at the show....be prepared for some ribbing for that
.
With DCS you don't have the radio problem as it communicates through the track. Which is why you had no issues running PS2 or PS3 engines conventionally on your layout.
You would need to be aware if you used DCS to set each remote on a different address and each TIU to a different address from other DCS users at the show.
Hope I explained that okay, and it sort of makes sense
Nick
