8.5. Problems when programming and controlling vehicles
A locomotive does not react to driving and switching commands, although you have entered
the correct locomotive address.
Possible cause: A wrong data format is assigned to the locomotive address. à Change the
data format.
Vehicles with DCC decoder
When programming a DCC decoder the mc² displays an error message.
Possible cause: You have selected a programming type that is not supported by the
decoder. à Check with the instructions for the decoder which programming types it is
designed for.
A locomotive with DCC decoder is already running at very high speed at speed level 1.
Possible cause: The number of speed steps "128" is assigned to the locomotive address,
but the locomotive decoder only supports 14 or 28 speed steps. à Change the number of
speed steps.
On a locomotive with DCC decoder the light cannot be switched and / or the light flickers
when switching up the speed steps.
Possible cause: The setting of the number of speed steps on the decoder and on the mc²
do not match. à Change the number of speed steps on the decoder or on the mc².
Vehicles with Motorola decoder
When switching up the speed steps for a locomotive with Motorola decoder, the speed is
actually changed only at every second speed step.
Possible cause: The number of speed steps "27a" or "27b" is assigned to the locomotive
decoder, but the locomotive decoder supports only 14 speed steps. à Change the number
of speed steps.
During operation locomotives with Motorola I decoders cause problems: They do not react to
driving and switching commands or have a bad driving behaviour.
Possible cause: The length of the signal pause is set incorrectly. à Change the pause time.
During operation, function models with Motorola decoders do not react correctly to digital
commands.
Possible cause: The length of the signal pause is set incorrectly. à Change the pause time.
