Reply to "MTH PS3 On DCC"

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:
   
   1. Bring up the CV menu on your DCC handheld
   2. Enter “29” to edit CV29
   3. Enter “38” to change the value of CV29 and hit Enter
   4. 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
5. Call up CV17 and enter the value required for CV17. You will get a two whistle/horn blast response
6. Call up CV18 and enter the value required for CV18. You will get a two whistle/horn blast response

In order to determine your required values for CV17 and CV18 you will need to go download the DCC VC17 and CV18 Conversion Spreadsheet (which can be found on the MTH website or you can use one of the many calculators on line)

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).

John, I have done this many times but not in a long time so I had to look up the instructions. There are many on line calculators you can use to find the values for CV17 and CV18. Here is one for example:

You just put in the 4 digit number you want to be the locomotives long address and the calculator will tell you what values to use for CV17 and CV18. Keep us posted.
