Locomotives or powered rail cars with NEM 8-pin connector.
Solder the wires to the correct solder pads according to the
diagram above. The brown wire with the ends of speaker wire is
soldered and insulated.
When installing the decoder in models with a sine motor the
wires for connections Aux 3 and Aux 4 may not be used.
Insert the plug into the connector while paying attention to the
positioning. Place the model, with the body left off, on the pro-
gramming track and test it. If the decoder works with no prob-
lems, the body can be put on the locomotive.

Multi-Protocol Operation
Analog Operation
This decoder can also be operated on analog layouts or areas of
track that are analog. The decoder recognizes alternating cur-
rent or direct current voltage (AC/DC) and automatically adapts
to the analog track voltage. All functions that were set under mfx
or DCC for analog operation are active (see Digital Operation).
Digital Operation
The mSD sound decoders are multi-protocol decoders. These
decoders can be used under the following digital protocols: mfx,
DCC, fx (MM).
The digital protocol with the most possibilities is the highest
order digital protocol. The sequence of digital protocols in de-
scending order is:
Priority 1: mfx
Priority 2: DCC
Priority 3: fx (MM)
Note: Digital protocols can influence each other. For trouble-free
operation, we recommend deactivating those digital protocols
not needed by using CV 50. Deactivate unneeded digital proto-
cols at this CV if your controller supports this function.
If two or more digital protocols are recognized in the track, the
decoder automatically takes on the highest order digital pro-
tocol, example: mfx/DCC; the decoder takes on the mfx digital
protocol (see previous table).
