Intermountain F7 QSI CV numbers needed

[Blind Bruce]

I am going further in testing my program track. I have a very reliable Intermountain F7 with QSI (113) decoder. Now I want to check and possibly change CVs. I have googled all morning and cannot find a SIMPLE table of CV numbers and what they control.I found the NMRA manual but it is more than I can comprehend. I put the F7 on the prog track and pressed the "1" button and that gave me the 113 manufacturer.

Bruce,

Here is a link to a 434 page manual to all CV's on QSI Quantum decoder.

Hope this is what your looking for. Not sure there is a simple table of CV's.

Bruce,

Here is another site from Digitrax that might be helpful.

Actually this link should take you there directly: http://media.wix.com/ugd/0f7119_33c33dacd2ff475f918159313227c7c2.pdf

Do you have any instructions that would have come with that loco?  That way you can be sure which decoder is in it rather than rely on the command station to tell you.

 

If you don't have the documentation, maybe you can contact Intermountain and ask them if they have any documentation.  I did look at Intermountain's website and the only DCC support they offer on-line is for LokSound, which makes me wonder if you really have a QSI.

 

Going beyond that, if you really have a QSI I would think it might be one of the Quantum flavors.  If that is the case here is a link to a Quantum user manual.  On page 9 is a list of basic operational CVs: http://media.wix.com/ugd/0f7119_1b253f400cf946eb9c036681bd56b43a.pdf

 

If you are looking for a list of NMRA "standard" CVs, they can be found on page about half-way down the page here: http://www.dccwiki.com/Configuration_variable#Mode_Control_.28CV29.29

 

What they mean about standard is that any decoder which is supposed to be NMRA compliant will use the standard CV number for any function (for example short address) as any other decoder.  But, that does not mean that all NMRA compliant decoders will actually have the function.  For example, even though it would be "standard" for a decoder to have Vmid on CV 6, if the particular manufacturer did not include Vmid, then CV 6 on that decoder would not change anything.

Thats the one Maxman. I tested the program by adjusting the horn volume. Now I know it works!

Many thanks to all.

Get the appropriate adapter for your DCC system and install JMRI on your computer.

It will read the decoder info and present you with either that specific decoder, or a list of possible choices.  Pick the correct one (or closest one) and it will give you everything about all the CV's in plain language, laid out in logical groupings (motor, lights, sound, etc).  It will also do the calculations for those CV's (like CV29) that need them.** 

You simply click on what you want and tell JMRI to write it to the decoder. If you create a roster entry for the loco (again, just a couple of clicks), it will also save all the CV info for that loco.  Better than doing a factory reset (which JMRI can also do, if you really want) and starting over from scratch.

There's no need to stay stuck in the 1980's with the limited abilities of hand-held throttles when it comes to setting up decoders that may have hundreds of CV's.

**JMRI does a LOT of other stuff, too.  It doesn't "just" program decoders...

As a matter of fact, I still have the keyspan cable I bought when I first tried JMRI. At that time, I had a Digitrax Zephyr and had some difficulty setting it up. I think I will try it again.

Thanks

Blind Bruce and maxman:

I have Intermountain F series locomotives with both Loksound and QSI from the factory. Its pretty easy to tell if you have a QSI because there is a honkin' great big square micro chip right in the middle of the QSI decoder.

FWIW, I'm likely going to dump the QSI and replace it with a Loksound Select when finances permit. Loksound works properly right out of the box. The Intermountain factory installed QSI required a bunch of fiddling to get it to start on speed step 1. That ticked me off given my experiences with Loksound. I will be consisting my F series locomotives. If the QSI won't play nice without a lot more adjusting it will be toast. (There I go pushing Loksound again! I think I should buy shares in the company, but maybe not because that would prevent me from ranting about them here).
