CV's 21 and 22
Posted by CPbuff on Friday, December 18, 2015 4:28 PM

I have a consist that I have set CV's 21 and 22 so I can use decoder features without going back and forth between the consist address and the loco address... These two decoders are both digitrax.

In another consist I'd like to do the same thing but I have a QSI Quantum Revolution-A in one consisted loco and a Digitrax DH163P in the other loco!

I can't seem to find anything about using CV 21 and CV22 in the QSI decoder! Does QSI allow me to set up CV21 and CV22? Or is this decoder incapable of doing it? I can't seem to find anything at the QSI website or manual mentioning these two CV's...

Using MRC Prodigy Advanced for control!

Thanks!

I suspect that you are looking in the user's guide, and that doesn't reference CVs 21 and 22.  But if you look in the reference manual for all Quantum decoders, http://media.wix.com/ugd/0f7119_33c33dacd2ff475f918159313227c7c2.pdf you'll find them on pages 53 and 54.

Having a manual that is 434 pages long for a decoder is absurd. You need a computer science degree to figure it out.

 Long <> complicated. The QSI manual explains each and every CV 1 by 1, not with just some quick blurb that says the default is X and the range is Y-Z, but details about what it controls and what it does, and what other CVs it interacts with.

 Sound decoders will always have more information - there are CVs that don't apply to plaine motor decoders, like all the volume controls. Those short 1 page MRC sound decoder manuals are completely useless as they don't even tell you much more than a list of CVs. No explanation of what the various options do, or what each function key does. They are short and 'simple' - and useless.

The decoder definitions in JMRI reference them so I assume they do since the definitions are based on info from the manauls.

Thanks Maxman for the manual which does explain CV21...somewhat for my limited knowledge... I set CV21 to 7 and get horn, bell and coupler crash from consisted ID, but for some reason I can't get Dynamic brakes and Audio mute... I understand CV 21 but what is the primary index and what is the secondary index for CV 21... or do I have to use another CV to set CV 21 to proper values! I've been away from this for too long! Still trying to scrape off the rust!
