The interaction between vehicle and Decoder Manager
With the Train Coupling & Communication System (TCCS) T4T enhanced the functionality of the digitally controlled
model trains considerably. If used as intended, not only can the traction vehicles and locomotives be controlled via the
DCC-protocol but also any imaginable function in the wagon as well as functions that develop from the interaction bet-
ween the vehicles. In doing so, the locomotives are controlled via LD-1x decoder. In addition, the vehicles are control-
led via the wagon decoders of the WD-xxx-series.
The decoder types are the being linked via TCCS respectively via the current-conducting, remotely controllable coup-
ling TC-H0 which establishes a 2-pole connection throughout the whole train (trainbus).
Why does it require a separate device, such as the Decoder-Manager?
The locomotives are always parameterized via the track interface in the service mode as defined by the NMRA.
This standard DCC-protocol interface supports basically all control units and is sufficient for all standard controlling
(conducting) and parameterizing (setting CVs) of locomotives. Now the wagons are equipped with the option to execute
functions such as controlling the TC-H0 coupling, the tail lights or the interior lighting, etc. As a result, the settings of a
wagon decoder can be changed if the factory settings are not sufficient for the required tasks, such as the adjustment of
the brightness of the illumination or the correlation of function outputs to the users.
Though it is possible to program the WD-xxx decoders via the connected locomotive, this is a tedious way that does not
allow the read-out of the variables. The Decoder Manager works like a locomotive with display and can therefore show
all CV-values on its display and allows the modification of the data.
