simonhaz Posted February 10, 2013 Share Posted February 10, 2013 Hi, I'm completely new to this. I am looking to build a layout. Will be aiming to get Elite DCC and Train Master. Could someone explain how you would connect a traintonics 2 aspect R/G or Y/G up to DCC. Am I correct in thinking it will be as simple as connecting it to the accessory decoder? How would you then also go about controlling a 2 aspect signal with 1 or 2 junction indicators (feathers)? Please be gentle with me, not an expert with electrics!

Fishmanoz Posted February 10, 2013 Share Posted February 10, 2013 If my memory serves me correctly, don't these include a decoder? If so, just connect it to the programming track, select an accessory address and you are away. If I'm wrong and they don't have a decoder,then connecting to an accessory decoder is the way to do it. I'll let someone else answer about junction indicators. Link to comment Share on other sites More sharing options...

Hi The TT signals whether or not supplied with a Junction Indicator (Feather) should ideally be worked by the TT301 dedicated decoder. This allows full DCC control of the signal aspects and the J/I too. It should work with all DCC systems that are NMRA compatible and the TT301 decoder controls a 2, 3 or 4 aspect signal plus a left and right J/I Google TT301 for further details.

St1ngr4y Posted February 12, 2013 Share Posted February 12, 2013 Hi, The problem with TT 4-aspect signals is that you have to repeatedly send signal clear's to step the aspects through their sequence. So if the signal is at red, a clear will set it to single yellow, another clear to double yellow, a third clear to green, and a fourth clear back to red. If a R/I is fitted, a stop message toggles the R/I on and off. What it means is that if the signal is at single yellow when a train passes, you want the signal to go to red immediately. However, because of the above sequence you have to send it 3 quick clear's in a row to achieve red, and double yellow and green flash briefly in the process, not exactly realistic!! I much prefer One-Touch signals by Train-Tech. These have their decoder built into their base - no larger than your thumbnail - and 4-aspect signals are given two consecutive port addresses, one for red/green, the other for single/double yellows. And yes, it CAN be switched directly from single yellow to red. The down side is that they haven't yet produced a signal with a route indicator, but I'm sure demand will be such that they could produce one with a third port address to control the R/I.
