Dave & Mike, you may forward my answer to the Yahoo group since I am not a
member.
Generally, you would use the decoder lock feature in both decoders in the
following fashion:
The decoder lock is used to change CV's in only one of several decoders with
the same short address (CV1) or long address (CV17 and CV18) that are installed
in the same locomotive. Assign a number to CV16 in each decoder (i.e. 1 to
motor decoder, 2 to sound decoder, 3 or higher to other decoders) before the
decoders are installed in the locomotive. To change a value in another CVof one
of the installed decoders, first write the number 1 (motor), 2 (sound) 3 or
higher (other) into CV15, then send the new value to the CV to be changed. The
decoders will compare CV15 to CV16 and, if the values are equal, the CV to be
changed will be changed. If the values in CV15 and CV16 are different, the
update will be ignored.
The motion decoder has two CVs that you can set to lock the decoder so it won't
listen to re-programming commands. If the DH465 follows Digitrax's standards,
then CV54 set to 0 enables the Lock function and CV16 sets the lock code, (It
is recommended to set the mobile decoder lock code to 1, and write down the
lock code or put it in the memo section of the Roster Entry tab of Decoder Pro
if you are using it).
Once you have programmed the motion decoder to act in the locomotive as you
want and locked it, then follow suit with the sound decoder.

Makes me wish I could help, but I'm still in the dark ages with my Variac, 19-B
transformer and TAB plate-set rectifier; still all one DC block for now. Dave

Subject: {S-Scale List} Dual decoders in the same locomotive
Gentlemen and (if we are so lucky) Ladies;
I am going to install a Digitrax DH465 into my 343 steam rebuild. It has the
heft and function outputs I need. Plus it is already on the workbench. This
locomotive will be programmed to 43.
I am looking at the MRC 1908 sound only decoder. The question is programming.
Do I program both to 43?
Do I program the motor decoder to 43 and the sound decoder to, say, 93 and
then permamently consist the 93 with the 43? Do I reverse this and consist the
motor decoder to the sound decoder?
How does one program a dual decoder locomotive? Am I restricted to
programming-on-the-main? Should I have a way to electrically isolate each
decoder and then use the programming track? If I isolate them, should they
both be 43?
Help!
