Jim K,
You will be able to pick the interface from the Roster screen. It will have
another select list, between the power buttons and the programming mode,
that will pick which system you will use for programming. At least it
should, I've not used that lately. Also there are select lists in the single
CV programming to pick the interface. So you should be able to have the
'LocoNet - PR3' and 'LocoNet - CS' to choose from as needed.
