Read about, then D/Led the latest veriosn of DecoderPro. Got to
admit, I like the selection system and screen layouts. Problem is I
can't get it to communicate with either my Digitrax EBII or to a
dedicated programming track via a PR-1.

What are the system interface requiremnts of this application. It
looks to me that it requires a Digitrax Chief or a similar system
which supports read and write, not just write functionality as the
EBII has.

Bob,

As you guessed, R/W is required at this time. That means the EB is not
supported.

Bob,
Digitrax is soon releasing the lower cost DCS050 and this unit has a
programming track. I am going to get one when they come out, probably June
or July. Depending on their specs. (it's not exactly known how they would
work with an EB) they might be a good combination with the EB which would
then give a programming track.

Sorry for the slow reply.

The Empire Builder doesn't have the ability to read from decoders. There's nothing a PC can do about that, unfortunately. DecoderPro should still be able to program them, and can keep records of the values you've stored in its roster. That'll help you keep track of what options you've set, and make it easier to make small changes.

If you click any of the buttons that cause a read operation, such as either of the "Ident"s, "Read All", etc, you should get a message saying that the operation failed near the bottom of the window. But the "Write All" and "Write Sheet" buttons should still work OK.

Bob,

When using an EB (I have a DCS100 not a BD150) you would have the problem of
not knowing the initial decoder settings, so does DecoderPro set all the
CV's to a particular value (0 ?) when you open the Programmer window?

After the user has made all their changed from this default above, does
clicking the "Write All" button write all CVs even if they were not changed?
If it does then you could be _fairly_ sure that DecoderPro's and the
decoder's state are in sync.

I have noted a few times people having problems programming decoders and
want to revert their decoder back to "factory defaults" to start again, but
I think that only a few recent decoders have a CV for this. Maybe a "factory
default" attribute could be added to DecoderPro's decoder config files, so
that resetting to factory defaults could be possible and configurable.

This might also be handy for people to create a baseline config that they
use to start from, although I note that you can do this with the copy/rename
functions talked about and maybe added recently.

Each CV has a default value specified for it by the writer of the decoder
specification. Some default to zero while other CVs have defaults configured
to be the same as the defaults the factory sets in the decoder. If I recall
correctly, the default values are displayed when you start the programmer.

After the user has made all their changed from this default above, does
clicking the "Write All" button write all CVs even if they were not changed?

Yes. The fields that are yellow are ones that DecoderPro will write when you
click 'write sheet' or 'write all'.

I have noted a few times people having problems programming decoders and
want to revert their decoder back to "factory defaults" to start again, but
I think that only a few recent decoders have a CV for this. Maybe a "factory
default" attribute could be added to DecoderPro's decoder config files, so
that resetting to factory defaults could be possible and configurable.

That would be a good idea. It would be difficult in some cases as not all
manufacturers clearly state the default values for all CVs, but it is a good
idea.

I think DecoderPro could do this now. Simply open the programmer using the
decoder type rather than roster entry. Then perform a 'write all'. This will
set all CVs to the default value. A specific button to do this from a roster
entry programmer window would be nice.

This might also be handy for people to create a baseline config that they
use to start from, although I note that you can do this with the copy/rename
functions talked about and maybe added recently.

It does look like Bob has a good handle on this one with the copy functions
that he is planning.

cheers,
Mike
