@BOB WALKER posted:Here's my reasoning on why a bridge from TMCC to DCC is questionable. Achieving interoperability between TMCC and LC is essentially the design of a link between system A and system B. In contrast, ea ch brand of DCC decoder offers a unique set of features and more importantly utilizes a particular approach to the all important management of CV's. Also, each brand has its set of strong adherents. So which one do you choose for the link project? Not a simple decision.
I don't think any of that matters unless you are trying to link a control system like NCE to the Cab1 for example. That be pointless anywasy because there are already things out there that are free and can do that.
DCC decoders are is designed around NMRA standards so they are consistent in physical function of outputs. Decoders that have sound will follow the same outputs of whistle and bell but everything past that will be mapped slightly different between manufactures. BUT since DCC is very user customizable....the user can map the functions in the KEY pattern they want.
LIKE I SAID BEFORE. The best way going about this is almost the same concept of BlueWire and AirWire 900 from CVP products. Where you have a board that goes between the input power from the track in the locomotive to the DCC decoder in that same locomotive and that board responding to TMCC commands via the radio signal converting into DCC commands for the decoder. (mini DCC station)
NOTHING is going between transformer and track. Track is the power supply. Everything is self contained in the locomotive.
