Multi-Protocol Operation
The decoders are multi-protocol decoders. These decoders
can be used under the following digital protocols: mfx, DCC
or MM.
Address set at the factory: DCC 03 / MM 77
The digital protocol with the most possibilities is the highest
order digital protocol. The sequence of digital protocols in
descending order is:
Priority 1: mfx
Priority 2: DCC
Priority 3: MM
Note: If two or more digital protocols are recognized in the
track, the decoder automatically takes on the highest value
digital protocol.For example, if mfx & DCC are recognized,
the mfx digital protocol is taken on by the decoder. Individual
protocols can be deactivated with Parameter CV 50.
Note: Please note that not all functions are possible in all
digital protocols.
Notes on digital operation
