Multi-Protocol Operation
Analog Operation
This decoder can also be operated on analog layouts or areas of track that are
analog.Thedecoderrecognizesalternatingcurrent(DC)andautomaticallyadapts
to the analog track voltage. All functions that were set under mfx or DCC for analog
operationareactive(seeDigitalOperation).
Digital Operation
The decoders are multi-protocol decoders. These decoders can be used under the
followingdigitalprotocols:mfxorDCC.
The digital protocol with the most possibilities is the highest order digital protocol.
Thesequenceofdigitalprotocolsindescendingorderis:
Priority1:mfx;Priority2:DCC;Priority3:DC
Note:Digitalprotocolscaninuenceeachother.Fortrouble-freeoperation,were-
commend deactivating those digital protocols not needed by using CV 50. Deactivate
unneeded digital protocols at this CV if your controller supports this function.
