Hi Donald,

I looked and found those but being electronically challenged was not sure they would work. May have to order a couple and give them a try.

Nothing to lose at this point.

I have found a replacement MOSFET transistor pair chip (8 lead device) for the one in the motor driver H-Bridge on QSI Revolution board used in the Walthers N scale Mallet loco.  I replaced the blown chip, and that fixed the decoder.  But the transistor pair chip on that  decoder has different markings than "ZXMC 3A16 0406".

I just checked and CV7 = 5.

 

This decoder does not show up on the latest version of JMRI, that I can tell and the tech at BLI said that it’s obsolete, doesn’t work with JMRI and is no longer supported. When our club train master tried to program the address using JMRI, the head/tail lights became deactivated and a number of other functions also either disappeared or were changed to totally different keys.

 

I bought the Heavy Mikado used and have no documentation. It evidently was made around 2004.

 

This is the email I got from BLI.

Hello Don,

We no longer support the QSI equipped locos. They have been discontinued, and the one you have there is over 17 years old.

Also, due to the age of that model and a lack of parts, we can no longer work on QSI equipped engines.  We will not accept that model for repair in our service bay anymore.

I can tell you that it will not be compatible with JMRI or Decoder Pro though.

Any support documentation we have for it can be found here under "QSI Quantum Sound Equipped Locomotives": https://www.broadway-limited.com/supportdocumentation.aspx

I will lay out the most common support tips and tricks for you here on a QSI loco:

I would recommend the hardware reset.

A video for the hardware reset procedure can be found here under "Hardware Reset for Quantum Sound equipped Locomotives" : http://www.broadway-limited.com/howtovideos.aspx

Written instructions are below:

Turn the power off on your track

*** If a Magnetic Wand was included with your model ***
Place the engine on the track
Hold the Magnetic Wand that came in the box with your loco (A small black plastic square with the Broadway Limited logo on it, rounded edge is the magnet), over the Relay switch (a small glass tube with a reed switch inside of it). Relay switch is located on the decoder under the tender shell.
Skip to Section 2

*** If there was no Magnetic wand included ***
Remove the Black jumper plug or flip the tiny reset switch to the opposite position
Place the engine on the track
Go to Section 2

*** Section 2 ***
Give the track power.
In DC spin the throttle up to about 75%
In DCC turn the track power on, select loco number 3, and turn the throttle up.
The engine should announce "RESET" or play the horn 3 times.

Turn the throttle down, track power off.
If you removed the jumper replace it now, or if you flipped a reset switch, return it to its default position.

Your engine should now be on address 3 and all settings restored to factory default.

To set a long address on a QSI equipped loco, you must first set CV17, then CV18, and finally CV29. ON THE MAINLINE USING YOUR HANDHELD THROTTLE. QSI WILL NOT WORK WITH JMRI.

A CV calculator can be found here:

http://www.2mm.org.uk/articles/cv29%20calculator.htm

You can use this calculator to determine what you should set CV's 17 and 18 to.
For example, if you want to set the loco address to 3751 - type it in the box labeled "Long Locomotive Address", and then click "-> Calc CVs".
This will display CV17: 206 and CV18: 167 on the right side in their respective boxes.

Program the long address (CV’s 17 and 18) on the main, (sending commands to DCC address 3), then send the command CV29=38 (or CV29=34 if you never use DC operations) to DCC address 3.
Lift the engine off the rails, place it back on them, send the throttle-up command to the long address that you just programmed, and see if you can blow the horn.

To read a CV:

Please set CV64 equal to the CV you want to know the value of on the mainline and listen for the verbal response.

For example, after the reset set CV64=1 in Operations Mode on the mainline using your handheld throttle, and the decoder should speak the words "C V ONE EQUALS, THREE".

As for upgrades - we do not do that here in the service bay. Our reason for existing is to get a model back to the way that it was intended to be when it left the factory floor - or as close as we can get. And that is primarily on warranty support.

Train Service Depot is authorized by us to do upgrades though, so if you want to inquire with them on what they will or will not accept for an upgrade and their pricing, they can be found online here: http://www.trainservicedepot.com/

Hope this helps, have a great day!

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 properly?    Why do you want to swap decoders?   Perhaps we can help get the existing running to your satisfaction.

  The QSI version 7 (and higher) decoder has several features that are only now showing up in high end decoders.   Features like working fully variable brake, Heavy Load (allows simulating climbing or descending a mountain grade with a heavy load) at the touch of F9 key.   Decoder query allows you to read the CVs while Programming On Main.  Built in speedometer, odometer, and a host of other features can be 'spoken' by the decoder by pressing F10 (Status Report).   There's a whole lot more that many people do not know.

Morgan.

You are correct - off-topic.  Should have been asked on the jmriusers list.

One quick comment that may also help others - please move to jmriusers if you need more help:

You can use JMRI for POM and save the file just like using JMRI on a service-mode programming track.  Look at the bottom right of the DecoderPro roster page;  there are 3 choices.  After selecting the desired roster entry select "Programming on Main' before clicking 'Program.'  You are now programming the address in the file you opened on the main track.  Save the file when done.

Re: Older QSI decoder

 

One question. How do you record CV's and changes with POM? The only way I know of to ensure proper documentation is with JMRI and the xml's. My approach was to save each xml as changes were made. And when finalized on the loco. Just keep the latest xml and the original. And after thinking about it. Even the original is not needed. One can always default the decoder to it's original state. But I like to save the changes as I go along just in case I want to refresh my memory of what I had done. When I only had the DCS50 and tried changing CV's POM, I found I was scribbling notes all over the place. Very un-professional. When I used the pt, I was still doing the same. So I had to buy a SPROG and hook up the PC for JMRI. Now I rely on JMRI and xml to keep a record of what I've done to the loco. In fact, I even print out the CV's on paper. Sorry if this is off target about QSI.

Re: Older QSI decoder

Dave Robinson
 

You're right Morgan, you can't read CVs on the main, only on the programming track.
However, QSI did provide this wonderfull 'CV query' facility, ie CV64, whereby you can ask the decoder (on the main line via programming-on-the-main) 'what's the value in CV x'.  In my opinion, that's the best thing about QSIs; I wish other brands would do this too.
Beware: if doing an indexed CV, you must set the primary index (and the secondary index depending on the CV) BEFORE querying the decoder.

CV62, Programming Acknowledgement, will also speak to you when programming on the main, but IMO it gets old fast.  That's why I turn it off.  And it interferes when a programming service like JMRI is doing indexed CVs.

I'm with KJ, I want to know how to it 'manually' rather than depending on the 'magic' of something like JMRI.  Don't get me wrong; I use JMRI or QSI's CVManager when it's convenient (like when doing _lots_ of CVs), but for just a few changes, I'd rather use POM with a keypad (Digitrax is my choice).  In my club, it's commonly not convenient to have a computer with JMRI up & running; your conditions may be different.  I do keep lots of notes on the fleet along with JMRI & QSI roster files too.

POM is fine but for some things you have to keep your wits about you, like changing decoder addresses.  And once in a while I muck things up and have to recover on the programming track. :-)

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 Kelly?

  If you have a replacement Titan I would use it.   There are so many feature upgrades in the vastly superior Titan.  Gone is the crappy prime mover (UFO whir) sound.

  The Q1 decoder can be repurposed into something else.   e.g.  a commuter cab car with horn, bell and lights.   I did a couple of commuter cab cars with repurposed Revolution decoders (great horns and lights, but lousy prime movers) turned down all motor and prime mover functions and it works beautifully.   Alternately, the Q1 would probably make a decent caboose decoder.

Re: Older QSI decoder

kjlovesya
 

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 Digitrax cabs to get to the POM stage.  Your Digitrax user's manual will help with that.   However, as Peteski mentioned, once you are there you can do the 'Query'.   QSI's Query is simply CV 64 = whatever CV number you wish the decoder to speak.

  The other feature Peteski mentioned is the 'Status Report'.   By pressing F10, the decoder will speak it's status.   While stopped, the decoder will speak it's address.  It will also determine if it's in an advanced consist and report if it is.   The manual also tells you how to use the Status Report to determine distance travelled, speed, a host of other features and which of these are verbally reported. 

  There is a caveat.  Accuracy depends on doing the math.  While the decoder will speak scale speed or distance, it's accuracy is determined by the circumference of the driving wheels and gear ratios.   The manual also explains how to program these into the decoder.

  There really is so much that these decoders can do.  I find half the fun, after setting up appropriate momentum settings, is using the variable brake realistically.     Learning is best done one step at a time.   :-)

Best regards,
KJ


Re: Older QSI decoder

peteski7
 

Morgan,
As far as I know, QSI decoders are the only decoders out there that use human speech for verbal acknowledgment of values written to CVs in POM mode (and only in POM).  You can also (literally) have the decoder read back a value of any CV, again on the main line only.

While the loco is on the main track, do a POM write to one of its CVs. Just make sure that you are addressing the correct locomotive while doing any POM.  For example write some value (like 5) to CV3.  Once you do that, you will hear a male voice speaking "C V three equals five".  Cool, or what?  :-)  Whether this feature is enabled or disabled is controlled by CV62. I have  heard that some users disable this feature as it might cause some problems.

There is also a verbal readout of any CV in the QSI decoders which will literally tell you a value of any CV in the decoder.  That is CV 64.  In POM mode write to CV64 the CV  number you want to find the value of.  For example, if you write 1 to CV64 on the main line, you will hear a male voice speaking "C V one equals three"  (or whatever value is in CV1.  This feature is safe to use.

All of this is described in that thick manual you are afraid of. :-)
Just go right to the page in the manual which describes CV64 and CV62, to explain how it works.

Another cool feature is that when you press F10 on your throttle the decoder will also speak.  When the  loco is stopped, it will speak its address, and when it is moving, it will tell you (in scale miles per hour) how fast it is traveling.

Hi KJ,

 

What caused it? A short on one of the motor leads, now fixed that I missed seeing.

 

I am looking at some possible replacements for the chip as I believe it is a motor control with 3 diodes inside.

 

I do have a few Q1a / Revolution A and U’s as well as some Titans, just hate to lose what was still a good decoder for sound and basic light functions.

Re: Older QSI decoder

 

Wow! This info you guys are providing is priceless. Let me ask a basic question. How do I get the loco to speak? Can I do that on the pt? or must it be POM. (Please give step by step for this novice) And this is the first I've heard that you can get a read back POM verbally. It has always been "known" that on POM, you can not read back. Up till now, I put the loco on the pt/remember I have SPROG and get read back on JMRI. Easy to do. But when I had "any loco" on the layout, I could never get read back - only make changes and never remember what I had before. I had to write everything down. With programming on the pt and JMRI, I always could see what I was doing. POM sounds like a little more dangerous to me. Up till now, I do use POM for CV's 2,3,4,5,6 but nothing else. All other programming was done on the pt/JMRI. And if I did make changes POM, I had to try to remember to get back on the pt to input them in JMRI. After all, JMRI and xml is the place for storage. I even keep a separate file on my desktop with all those old xml's and only keep the latest on my laptop. So, just FYI I now have 3 xml's on this QSI loco plus one sent by a friend. When I get finalized on the loco, only the latest will be easily obtained. All others being on the desktop must be transferred to the laptop/via flash drive if needed. But in reality, that's very remote. Because with all my locos except QSI are finalized. Thanks again to a bunch of really nice people!

Re: Older QSI decoder

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 is very similar to Decoder Pro.

  Conversely, you can program the more tedious (but frugal) way, by individually programming each CV using the manual as a guide.  (That's actually how I first learned the Revolution decoder - What can I say?  I wanted to learn.)

Re: Older QSI decoder

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 x* is whatever CV # you wish to hear the value)  
In the case of version number you program CV 64 = 7.  The decoder will 'speak'  something like, "CV six four equals seven."

Re: Older QSI decoder

KJ, must have been a typo; that CV should be 64 instead of 62.  7 into 62 won't be good when diagnosing problems especially when using JMRI.
Otherwise, excellent answer.

Q1 Motor Diode Chips

ffbrehm@...
 

Hello all, this is my first post since the group moved from Yahoo.

I smoked a Q1 decoder from a Proto GP30. The chip is next to the motor connector. Number is ZXMC 3A16 0406. I believe it is for motor control. Does anyone know where or if these chips are available?

Any help is greatly appreciated. I would just like to save this decoder instead of using a revolution. This locomotive only needs headlight and reverse lights.
