All the Atlas decoders I have work fine on four digit address. I have some
from the very first run of the Master GP38, number 340 as well as the later
version numbered 341 (don't yet have a four function number 342 decoder). I
don't think Atlas ever said the decoders did not support four digit, they
did say there system did not support four digit.
Did you also set CV29 to allow for four digit addressing? A value of 34
decimal sets CV29 to be four digit, 28/128 speed step, no analog conversion,
no speed tables, forward direction. There's no special config needed, just
set CV17/18 (long address) and CV29.

Subject: [jmriusers] Anomolies
All
I ws programming some locomotives at a friend's operating session last
night and found a couple of anomolies.
One friend had just gotten a brand new DSD-100LC-AT from Soundtrax and it
has software version 35 which DecoderPro said it didn't recognize.
The second one is a little more complicated. He has amassed quite a few
Atlas GP-38s. Without trying he ended up with two road names that had the
same last two digits of the road number. He asked me to find a way to give
them different but easily recognizable numbers. I took the first one and
fired up DecoderPro and promptly changed it to a four digit number. I was
elated, this was going to be easier than I though and Atlas has been lying
to us about the decoder's capability.
The second locomotive would appear to take a four digit address but when
you tried to operate it, it was still responding to the two digit address.
When I went back and read the CVs, sure enough it was only two digit
capable.
So the question becomes, did I get an Atlas decoder with an Easter Egg?
Or is there some special configuration that will allow an Atlas decoder to
accept four digit addressing? Both decoders report the same software
version (45).
Any ideas?
