I recently completed the installation of a Soundtraxx ECO-PNP decoder in a Proto 2K SD9 loco. I set it up here with Decoder Pro. When I ran it at the club I made a few tweaks to some settings while I was there. Now back at the house I wanted to save those changes to my Decoder Pro files on my laptop but all of the "Read" buttons are grayed out so I can't extract the settings from the decoder to save them. What am I doing wrong?

Have you noticed since everyone carries around a camcorder these
days that no one talks about seeing UFOs any more?

My guess is that you've opened the roster entry in "Edit" or "Program on Main" mode rather than "Program Track" mode.

Or you may have a connection/configuration problem and JMRI cannot talk to your DCC system.

The connection is good. Decoder Pro identifies the loco when I press the Identify button. I thought that "Program on Main" was able to read CVs like "Program Track". At least I thought it did with a few previous engines that had factory installed decoders, but now I'm not sure.
I was wondering if the Economi series of decoders didn't support reading of CVs. My understanding is that in the early days of DCC decoders didn't support reading, but I thought all modern decoders did. I'm new to actually using DCC, but have read various articles over the years that it's been available.

Rick,

You only get readback on the programming track. Program on the main is
strictly a one way deal. At least for almost every system, a few with a lot
of extra hardware do create a limited reading ability. That's either RailCom
or Transponding and very few people use it successfully.

Retried it and that worked. I'm new to this and still learning.
Now I'm wondering about the difference between the three address fields on the Basic tab.

What do you call a fish with no eyes? A fsh.

The three address fields work out to the stored 'short' address (CV1), the
stored 'long' address (CV17+CV18), and the 'effective' address that is the
one the decoder responds to. Also there is a funny formula for how CV17 and
CV18 combine to make that 'long' address.
