Dave,
Thanks for the trick with the long and short addresses for multiple
decoders within one engine. I was fiddling with cumbersomely positioned
jumpers all the time when I needed to program something, and this is SO
much easier! True, a bit more discipline is needed when going at it,
because not taking very good care in choosing POM or Program Track can
cause a real mess, but it's a small price to pay.

I haven't heard of the Phoenix decoders either. There are other brands of
sound-only decoders represented in JMRI.
As far as two-decoder locos are concerned, you just have to create two
separate roster entries, one for each loco. They will have the same DCC
address, but that is no problem for JMRI. However each loco needs a unique
ID so you could do something like "xxxxxx - motor" and "xxxxxx - sound" for
the two IDs, that way they will stay adjacent if you sort by ID.
There are special considerations for programming dual-decoder locos:
- Sometimes the two decoders have no conflicting CVs so you can simply
program both in tandem. But you will generally not be able to read back CVs
in this configuration.
- If both decoders support the NMRA Standard CV15/16 locking you can set
up different decoder type IDs in CV16 and use CV15 as the key to unlocking
one or other decoder. But you will have to separate the two decoders
electrically to initially set up the unique IDs. <
Decoder_Programming_Lock>.
- If the decoders do not support CV15/16 locking you can set up different
short addresses in CV1 with a common long address in CVs 17 & 18. You then
use the long/short address selection bit in CV29. With long address
selected you drive the loco. With short address selected you can program
each loco separately. But you will have to separate the two decoders
electrically to initially set up the unique IDs.
- Or you just separate the two decoders electrically to program them and
reconnect when finished.
If all this sounds complicated and confusing, that is one of the reasons
most of us avoid sound-only decoders like the plague (there are other
reasons as well).

Hi All, I run 1.20.3 locomotive with dcc and have just started using
JMRI. I have added some of my locomotives to the roster using Panel Pro and
have not had too much trouble. What I don't understand is how to add a
locomotive which uses one decoder for motor (NCE D405SR) and one for the
sound (Phoenix Sound PB11) in the same locomotive. The NCE decoders seem to
be well represented but for sound only like Phoenix I don't see anything
listed. I don't know how to create a loco in the roster with two decoders
in the same loco even if both were in the decoder list. As I said, I am new
to JMRI and it is a little overwhelming in the beginning so please bear
with any dumb questions I might not realize I am asking.
