NSColsMP6Is this the case, and if so, why not just ship them with the DCC jumper in DCC mode if it can accept either DC or DCC inputs by default with this setting?
For the first time, modelers are able to run a decoder-equipped locomotive on a standard DC powered (analog) layout, without experiencing the typical speed differential.
NSColsMP6 Before I could run my Atlas DCC locomotive, I first had to change a jumper to switch from DC to DCC. Then I was reading the manual and saw that CV29's Bit 2 is set to 1 by default (page 5 of the manual). This would seem to imply that if I placed the engine on a DC layout, it would run without replacing the jumper to it's original position. Is this the case, and if so, why not just ship them with the DCC jumper in DCC mode if it can accept either DC or DCC inputs by default with this setting?

I think manufacturers may have changed their default settings over time. It's been awhile since I've opened the box on an Atlas dual mode decoder. Most other manufacturers don't have both a jumper and a CV setting to set analog/DCC mode. I also thought that CV29=6 was a pretty common default setting. If you use Digitrax or other similar decoders, there are no jumpers. Just the CV29 setting for the mode.
