Long loco addresses - issue setting up

[model-trains]

I am endeavouring to change to long loco addresses. I have a Class 66 044 currently with a short address, I am wanting to use 6640 as this loco's address.

 

First  have run a DCC Extended Address Calculator

For address 6640 it provides...

CV17 = 217

CV18 = 240

 

I have then done the following...

CV29 - write 29

CV29 - write 38 to edit

Next

CV17 - write 217

CV18 - write 240

 

The Railcom address, the loco address remains at 3, have I done something wrong here?

 

I am using iTrain 5 software, reading and writing CV's on the main track (RailCom)

I don't understand why you are writing 29 to CV29 and then writing a value of 38.  You should only need to write one figure to CV29, depending on which features you want - see http://www.2mm.org.uk/articles/cv29 calculator.htm

 

A value of 29 in CV29 would imply a short address, while a value of 38 would imply a long address, but with Railcom turned off.  Do you want to use Railcom?

 

The values in CV17 and CV18 look okay.

Hi David

 

Yes I wish to keep RailCom,.

 

I got the information from a website regarding writing the two items of data to CV29

 

I have written 217 to CV17 and 240 to CV18, but it is still recognising address 3 in CV1 loco address?
