No, the consumer must insure the product they are purchasing conforms.
Soundtraxx and Bachmann do.
2.2.1. Command Station output signal
A bipolar signal must appear differentially on a two-wire cable with a signal amplitude of no less +-8V and no greater than +-22V.
And, you might want to read this:
http://www.nmra.org/standards/DCC/standards_rps/S-91-2004-07.pdfThe max is 24v, if I recall.
The minimum spec I've been told is 21v on the track, and Soundtraxx meets that.
The issue you have needs to be taken up with Soundtraxx about voltage.
Bachmann doesn't build them, Soundtraxx does.
And, as I've said before, if the consumer doesn't know what to do, they need to either learn or not do it.
The posts of folks wanting to know how to remove a shell, then install a decoder, is mind-boggling.
If someone hasn't the skill to take a shell off, they need to learn how.
Asking is fine, but to ask both at the same time is beyond me.
Like newbies wanting to know how to edit their registry.
At 23.8v on MTS, they are pushing the 24v max anyway.
In electronics, you never want to be that close.
All this is what I've read and been told, and even after 40 years in electronics, I am NOT INTERESTED in ANY KIND of dcc control.
If I want to run trains, I want to run and not mess around with a freaking computer or setting CV's.
I want to know where the wire goes, what the max current is (try to find out THAT information on OEM stuff) and something easy to fix.
In 15 years, guess how many radio control units I've had to rip out because they failed?
