44 tonner decoder info

[fritzandotto]

Is there a manual or fact sheet for the 44 tonner decoder other than the sheet supplied with the loco?

I called both Bachmann and Lenz in order to track down a decoder sheet that details the CVs. While I did get help over the phone, it's not the same as a printed sheet, which would be easy enough to include with the loco...

The decoder is a 4.4 XF or a 4.5 XF, similar to a Lenz Value Line.

It compares with the old LE1000. It does NOT have CV05 (top speed), or CV06 (mid). Also, it does not have a speed table.

Stealing from the LE1000 sheet, this decoder probably has:
CV01 (short loco addr) 1-99 [3]
CV02 (start) 1-31 [10]
CV03 (accel) 1-255 [1]
CV04 (decel) 1-255 [1]
CV05 (CONTAINS ONLY A MIRROR OF CV29) 0-39 [6]
CV07 (decoder version)
CV08 (MfgrID) NOTE this is NOT a Lenz ID; This CV serves another purpose: reset.
CV08 (reset) Writing a value of 8 into CV08 (MfgrID) resets all CVs to factory defaults
CV17 (high byte of long address) 192-231

• 
  CV18 (low byte of long address) 0-255
• 
  CV19 (consist address) 0-255
• 
  CV29 (config) 0-63 [6]
  CV50 (decoder config byte 2; special settings) 0-12 [4]
  CV51 (Light dimming for function output) 0-255
• 
  CV52 (dimming CV for function) 0-255 [255]
  CV105 (user CV #1) 0-255 [255]
  CV106 (user CV #2) 0-255 [255]
  CV128 (decoder software version) read only
  
  If you are familiar with values for CV29, you can see that the range of allowed values don't go high enough to permit a speed table...
  
  I hope this helps!
  
  Note that this is the best info I've been able to assemble. I make no claim that it is 100% correct. I still have to take the computer to the layout and use DP to check everything...
