I've got an O scale C424 and a QSI Titan FX-DO decoder to be mated with it. I only recently noticed that the new decoder came with the wrong sound file. The prime move is the ALCo 251 but the sound fi

I just did a little more inquiry. The top page of my decoder paperwork is labeled FX-O-TOP . That's what I reported above. However, when I ran the QSI software it reported: FX-DO 7021 hardware. Kelly

Hi Joo, Thus far you have suggested you'd like to purchase 1/ a QSI Titan FX-DO and 2/ a QSI programmer. All of these items are new in stock at QSI. Why don't you simply ask QSI? Kelly is from QSI and

Hi Joo, Sorry, the decoder is not for sale. I have a locomotive in which I want to install the decoder. I'm not sure that we have the same decoder. I just checked, mine is the Titan FX-O. # 670-0200.

Hello Joo, Sorry about your name spelling. I don't know how to type accents on my keyboard. I have a new in box Titan FX-DO and just had a quick look. There is a error on the drawing for the bottom bo

Hi Paul, I highly recommend first downloading and reading the smaller Revolution - U User's manual. Many of the Titan connections are the same as the Revolution's connections. I find, for someone new

Hi Don, I'm not familiar with a version 5 decoder. However, you can easily try turning off the 'acknowledgment' that interferes with double CV changes. Try POM --> CV62 = 0 . Then try running the JMRI

Hi Frank, Thank you for your reply. Come to think of it, Kelly (of QSI) mentioned the motor output runs through an H bridge chip. I don't know about availability. Have you tried directly contacting Ke

Hi Morgan, I wish to add to the above. The steps to Programming On the Main (POM) is slightly different depending on the manufacturer of your DCC system. I don't remember the button sequence on the Di

Hi Frank, Unfortunately, obsolescence is a thing. I know that's why QSI went to the Titan design instead of continuing the Q1a / Revolution decoder. I don't know if components of that era are still av

BTW Don, You don't actually need a QSI programmer for CV management. You can use either JMRI Decoder Pro or (if you have an NCE DCC system) download the free CV Manager program. The CV manager program

Oops! Yes, it was a typo. <laughing> as I wrote the word "typo", I actually typed "type". *GRIN* Thanks Dave! Don, my apologies. When doing a CV value 'Query' you Program On Main --> CV 64 = x* (where

Hi Don, The QSI decoder is JMRI compatible. What version (CV7) is the decoder? (Hint: Program On Main --> CV 62 = 7 ) If you were able to set it back to factory settings does the locomotive run proper

Hi Morgan, Your situation is exactly the purpose of this forum. We are here to help. I suggest going through the Revolution U - users guide first. Obviously, it's for the Revolution U decoder installa

Hi Morgan(?), The version 7 decoder has (among other things) a 'variable brake'. In order to use the working brake, one needs to have momentum values above 0 (zero) and BEMF turned on. I highly recomm

You make a good point. However, it is a challenge to make user friendly a sophisticated device, such as a QSI Titan sound decoder. The complication is of necessity. I think QSI has done a very good jo

Whew! Yes, I think you have it. :-) Best regards, KJ P.S. The K is for Ken not Steve.

Bruce, Dave's answer is correct. I would like to add a little clarification to the bit 7 issue. Please bear with me. I'll try to write this for everyone to understand - even those who have no idea how

Dave, thanks for pointing out my error pointing out Greg's error. Hehehehe! Yes, the correct CV number is 1 for short address. CV2 is for slow speed minimum. Nick, thanks for pointing out the talk bac

Greg has highlighted one of the really useful features in the QSI Titan, Revolution and all version 7 decoders. The decoders can 'speak' using the CV 64 query. The example Greg used needs a slight twe
