Changing a CV via itrain

[Seamus147]

Back again after hours of grief,   Firstly let me say if it wasn't for the itrain tutorial series i would not have a clue where to start......... Well done Guys, thanks.Obviously i'm back and forth in the videos untill i get it right, however i'm stumped with this one.   It may be very simple ................  but if you don't know ???

 

I'am trying to follow the procedure to create an appropriate Speed profile.   On a programming service track via itrain.  i successfully change the CV address 1 from 3  to 18.  and the accel and decell from 5 to 0    

 

i've included a pic  to help explain myself.   

 

Can somebody please explain what's happening here,  i've tried a variety of Max speeds  but the Loco still runs at a max 124kph when tested on a 3 metre run.

 

Why cant i change it ?   what are these 'no entry' signs,  i presume they just mean the change has not been accepted.  I've found absolutely nothing on the web ref. that symbol, not a mention anywhere. 

 

Thanking you in advance.

May I suggest that the best place to ask detailed questions like this about iTrain is on the iTrain forum?

iTrain (English) - iTrain forum (berros.eu)

 

You should also include the TCDZ file for your layout, plus make and model of decoder that you are trying to program.

Thanks Iain,    i've ordered new decoders as i dont have confidence or info on this one.

 

I'll follow your lead.   i would like some explanation, i'll get there eventually.

 

Thanks

CV 7 version 131 suggests a TTS decoder by Hornby and that does not support changing those CVs so I reckon iTrain has got it right.
