Lionel 255 - Feature;Factory Resetting

To change your engine's Long Address using PoM:
1. Call up the current engine's address on your DCC handheld
2. Enter Programming on the Main on your DCC handheld
3. In this step you have to tell the MTH engine that you want it to start
looking at long addresses. You do this in CV29:
a. Bring up the CV menu on your DCC handheld
b. Enter “29” to edit CV29
c. Enter “34” to change the value of CV29 and hit Enter
d. The engine will give you a two whistle/horn blast response
4. In the following steps you will now need to write values to CV17 and CV18 to
tell the engine what the long address should be
Feature/Factory Resetting
If all else fails and you aren't sure of something, never fear. You can always get
your engine back to a known state by either performing a Feature or Factory
Reset.
There are a couple of ways to reset your MTH PS3.0-equipped engine:
Factory Resets – Clears everything – takes engine to just like it was
when you got it brand new
l Send a decimal 08 to CV 8 to reset everything
entirely back to factory default
l Send a decimal 192 to reset everything except user
speed tables
Feature Resets – There are a couple of Feature Resets that you can use
l Press F28 twice (toggling on then off). This resets the
smoke, volume and lights back to their defaults
l Send a decimal 64 for a Feature Reset. This resets
volumes, smoke and light settings.
l Send a decimal 128 to reset only address values back to
factory default
l This is the same as writing 55 to CV55 to
engine address 55
Note: The engine address has to be
something other than address 55
Lost or Unknown Engine Address and the 55-55-55 Address Reset
In some cases you may not remember or have somehow lost the engine address.
Following the above Feature or Factory Resets will allow you to recover an engine. The
limitation to this is that for most resets you must know the engine address. If you are
