getting confusedof programming decoders

[bodiddle]

I am fairly new to dcc and have only bought 3 bachman decoders (the 3 functions one).

Because of the problem in getting these at the moment i went for the Hornby sapphire r8245.

what i dont understand with this decoder is how do i know what the F functions are for this decoder?

You see the Bachman decoders told me this on the instuction sheet but this Hornby makes no mention of them.

Whatever function button i press nothing happens except for the light on/off switch on the dynamis controller.

i really want the shunting mode, but what number function button is it? Do i have to programme this myself ad if so how do i do it?

thanks for any replies.

Shunting mode is enabled by setting CV112 to 1 and disabled by setting it to 0 according to the manual on the Hornby site (which they have hidden so you can't sensibly find it).

thanks Adrian i looked for that on Hornby site and couldnt find it!

i see that the default on the decoder is set to off which i will change but what function button will control it when i change the cv setting?

 

As far as I can tell, once you change CV112 the loco is in shunting mode (no function for on/off), so you would use programming on the main to switch modes. It's not the most elegant way to implement it.
