Bob J,
I don't know if I've uncovered a bug in version 1.1 or if I'm having
trouble programming a 4-digit address simply because I don't
understand the mechanics behind doing so.
During reprogramming of min/mid/max voltages for a Digitrax DN121
decoder, I ran into a situation where DecoderPro set the address of
a previously programmed and functional decoder to 03. This occurred
even though I had entered a short address of 86 and a long address
of 1586. I've been able to replicate this twice through the
following steps;
- Utilize a suitable method to program a DN121 decoder with a
short address of 86 and a long address 1586. Set the decoder to use
extended addressing then test it to ensure the address has been
correctly programmed.
- Open DecoderPro then select Program Track, moving to the
decoder selection window.
- From the Digitrax drop down list, select and open the
programming pane for a DN121 decoder. Do not utilize an existing
profile.
- Once the programming pane opens and the default values are
displayed, change the short address to 86, the long address to 1586,
select the 4 bit extended address button then write the sheet (not
all.)
- At this point you'll need to move the loco off the program
track and onto the mainline. Once there, attempt to run the loco
utilizing long address 1586. If the problem was successfully
replicated, the loco won't respond. Change the address on your
throttle to 86, the loco's short address, and try again. Again the
loco won't move. For the final test, select an address of three on
the throttle and test the loco once again. This time it should
move. ¨C but why, it's address is supposed to be 1586!
Please also note that DN121 decoders do not sport a speed table. The
inclusion of such on this decoders' programming pane may lead some
folk to believe it does. Not a problem if they don't utilize it, but
it can sure be frustrating for newbie's who don't know better.
Believe me when I say I know those frustrations all to well!
