A bit of help and advice needed please, from anyone out there who is a bit more familiar than I yet am with the SPROG and the Decoder Pro software....
I'm trying to read and adjust a Massoth LS (installed in a loco) using the SPROG, and it reads all the CVs correctly except for CV7, where it keeps throwing up an error message of "301, no locomotive present". When I go to the full CV list in Decoder Pro, CV7 is highlighted in red, but all other CVs seem to read OK.
According to P.29 (the full CV list) in the LS manual, CV7 is listed as both "software version" (listed as read-only), and "Decoder reset functions".
The other odd thing is that the page for the light functions (in Decoder Pro) is unavailable (greyed-out), whether or not the lighting connector is plugged into the LS - I've tried it both connected and not. However, I can put values into all the lighting CVs individually using the full CV list page (eg: CV50, light dimming value), and it seems to recognise and save the changes.
Anyone got any thoughts? I'm wary of putting the loco on the track on DCC until I've sorted this out, though I have actually tried running it on analogue (without the lights connected) and it runs fine with all the usual analogue sound effects working.
Thanks in advance,
Jon (zerogee)
