Another decoder question -

After I set a CV value and then read it back, it always comes up P255 no matter what CV I'm reading back....

toughts??

 

What command station are you using?


Stay cool and run steam.....

 

Oh yeah, Zephyr

Also re-installed decoder to make sure it wasn't loose.

 

I have one Digitrax decoder in a SD-26 that does the same thing. If I read any CV it shows 255 but I can write to it and it accepts the change. Since it takes the change I never pursued it further but I did notice the other day when I went to change CV29 from 50 to 51 the decoder all of a sudden started to read back the correct value.

Must be a bug in the chip. I also use a Zephyr. Does your decoder accept the changed value?

 

Supposedly, but the loco still performs at the default (i.e. warp speed) rate.
