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 the following steps you will need to write values to CV17 and
CV18 to tell the engine what the long address should be
In order to determine your required values for CV17 and CV18 you
will need to go to
https://mthtrains.com/sites/default/files/CV17-
CV18%20Spreadsheet.pdf
Enter in the long address you want then click anywhere else in the
spreadsheet and it will return the values for CV17 and CV18 (it will
also return the hex conversion of the CV17 and CV18 values if your
DCC system requires this).
Below is an example for extended address 2011:
4. Call up CV17 and enter the value required for CV17. You will get a
two whistle/horn blast response
5. Call up CV18 and enter the value required for CV18. You will get a
two whistle/horn blast response
6. In this step you have to tell the M.T.H. 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 “38” to change the value of CV29 and hit Enter
d. The engine will give you a two-whistle/horn blast response.
NOTE:
If you have elected to use PoM and did not start-up the
sounds of your locomotive, you will not hear the two-whistle/horn
blast response.
Feature/Factory Resetting
Please note, when making setting changes in DCS or DCC, such as
address, please wait a minimum of 5 seconds after removing power to
ensure the settings are stored in the engines memory. Reapplying power in
less than 5 seconds may result in losing the setting changes. 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.
