HH-8 CVs

[rprdds]

I want to run my HH-8 in reverse. I know there's a CV that can be set to change the forward direction but I can't find a CV table for the decoder. Can anyone help me?

[rprdds]

Maybe a further explanation might help. I know CV 29 is used to change the forward direction of the locomotive. When I try to read CV 29 my cab returns a no decoder message. How can I access the CV?

I believe that CV29 Bit 4 sets the NDOT to Rev...that needs to be ON

But if You cannot connect to the decoder You will need to resolve that issue first
