    • Does anyone have experience using a three wire pulse generator/hall sensor on a sound decoder without a specific connector for it?  I've installed a Massoth Pulsed Generator into an LGB Uintah steamer originally to connect to a Massoth XLS Sound decoder which has the three pin connector for the pulse generator.  But now my customer instead wants me to install a Phoenix P8 sound decoder which as a connection for a two lead chuff reed switch.  The Massoth decoder documentation indicates the three lead pulsed generator connections as:  Ground; Clock; 6.5 volts.  So, I'm not aware whether the Phoenix decoder can support a pulse generator without a clock feature?



      Note:  I've posted a photo of the Massoth Pulse Generator unit that I installed into the LGB Uintah, for those not familiar with pulse generators that produce the chuff input into a decoder's clock connector.

    • Greg - Specifically, the Massoth S Decoder's Installation Manual states on page 14:  ......."Clock2 is the connector for a second pulse generator, e.g., for cog wheel steam loco Ballenberg.  A reed switch (illustr. #9) can be used as a generator input in this case."  So, the Manual is incorrect about using Clock2 for a reed switch.......doesn't work properly as Roger Bush had found.   Roger did not send me a copy of the read out of all the decoder's CVs that you prepared, instead I did my own using the Massoth Service Tool.  I didn't review all the CVs but focused on adjustments to the CVs I thought would make the simulation chuff work better.    Roger complained that the simulation chuff started before his locomotive even started to move, so first testing an S Decoder I had in stock, I installed it on my test stand motor block, and the S Decoder's Simulation chuff worked fine.  Without having Roger's locomotive to adjust the chuff rate to the locomotive's movement, it would be hard to make the appropriate CV adjustments on Roger's decoder........he did provide me with the voltage his loco would start to move, 6.5 volts.  But his primarly interest was to use the Clock2 and a reed sensor for creating the chuff sound, so that's what I then focused on and received guidance from my Massoth Dealer in Germany.

    • That's great Tom... so again my takeaway is you cannot use clock 2, even though nowhere in the documentation this is stated.

      Also, I assume you got a copy of the printout of the CV's as provided to Roger, and there were ones set to very strange values, did you notice this?

      Make sure you archive the complete list of CV settings, so if the decoder is ever reset, you can set it back.


      Am I correct in assuming it is now using the Clock 1 input for the chuff trigger.


      In any case, congratulations!




      Greg - I'll respond for Roger since I set the CVs for him.  Yes, I found out from my Massoth Dealer in Germany that Clock#1 can work with a two wire reed sensor besides the Massoth three wire pulse generator/hall sensor.  I used the first two connectors:  Ground; Clock1.  The Massoth unit also uses the third connector +6.5v.  I provided Roger a Massoth three wire cable so he can solder his two wire chuff sensor to it and then just plug it into the decoder's clock connector instead of having to solder the wires to the bottom of the decoder.  I also provided him a print out copy of all the decoder's CVs read out:  Contains the current setting of each CV along with their default and the setting maximum and minimum range available.........a nice feature of the Massoth Service Tool.

    • But now you know how to tame the beast. The hard part is over.

    • At long last the saga finally reaches the last chapter. I have received the decoder back from Tom White who programmed it to do what I expected it to do last July - and it now does exactly that! I have installed it in the tender of my mogul and I now am able to hear chuffs determined by reed sensor and magnets on a wheel rather than the "automatic chuff" as advertised by Massoth. This will likely be the only Massoth decoder I will ever own!

    • Your experience parallels those that are common on GscaleCentral (in the UK for people that aren't familiar) and one of the moderators is pretty much an expert on Massoth, and he is sold on using the tool and the "sheets" and fine tunes them until they work.

      It appears to me that using the templates programs all the CVs specified.


      I indeed did a basic reset, and it took a bit of playing to get CVs to write consistently. My Zimo unit was most successful as the programming current is programmable, although the NCE has more control and flexibility over the 3 different programming modes available in service mode.


      Suffice it to say I'm not real impressed with the Massoth decoders and definitely not for people who do not want to become experts in programming.

      So the bottom line is use clock#1 only not matter what the documentation says, and, as I have seen on the European sites, get the massoth service tool and slam one of the files down it's throat (rewriting a bunch of CVs) because a simple reset really does not fully reset the decoder.




      Greg - I tried several times to change CV196=255 (chuff simulation) to CV196=0 (chuff sensor) plus several other CVs using the Massoth Service Tool but most wouldn't permanently take.  So I finally did a CV7=55 basic reset and then I was able to make the changes.  Let's face it, Roger's decoder has been through the ringer with so many people (Roger/Massoth Dealer/Mohammed; you; Massoth Technical-Germany; myself) trying to make CV changes using different DCC wonder it needed a reset when I tinkered with it.  So I wouldn't necessarily ding Massoth for that issue.  But you're right, some of the Massoth documentation's German to English translations are a little vague or inaccurate.  And while I've made many successful CV changes to Massoth decoders using the Massoth DiMax Navigator handheld controller and my Piko Central Station, the surest, fastest and easiest approach for volume CV changes is to use the Massoth Service Tool software (must also use the Massoth PC Interface device).  I'm sure there are many other decoder brands that also have their quirks.  And, under the circumstances, it was extremely helpful that I have a Massoth Dealer in Germany to consult with on Massoth issues.......he knows the products and also has a direct communications channel with the Massoth Germany folks speaking German to German!

    • Okay - The Massoth S Decoder is working fine using a two wire chuff sensor and magnet.  CV196=0 which turns off the chuff simulation.  I had to first do a decoder reset using my Massoth PC Interface Tool/Massoth Service Tool system.......I couldn't at first get the CV196=0 to take.  There had been so many people involved making CV changes trying to help out that it needed a reset.  I also unsoldered the wires that Roger had installed on the bottom solder connections which were for using Clock#2.  Instead I'm providing Roger with a Massoth cable connector he can use that plugs into the Clock connector on the top of the decoder.......he can then solder the two wires from his chuff sensor to this connector.  

      Note:  It's best to use the Massoth PC Interface Tool/Massoth Service Tool software to make CV adjustments on Massoth decoders, especially in this troubled-decoder situation, although I first tried using my Massoth DixMax Navigator which will usually work fine.

      Case closed.

    • Roger - I'm going to send you an off-line email but since I'm currently online with this forum posting in the General Forum Topic, I thought I'd also share my findings with ALCON, as we said when I was active duty Navy officer (All Concerned).

      I heard back from my Massoth Dealer in Germany who has a direct line and standing with the Massoth folks.  The finding is that the Massoth decoder's Clock#2 is to be used only for one specific locomotive that needs it, 

      1. The clock#2 is only to be used for a special locomotive, the Ballenberg, for the control of the steam cycle when the locomotive drives in the rack. For the clock control only the clock input #1 should be used.

      My comment:  The Massoth Installation and Configuration Manuals do not explain this.

      2. The Clock#1 chuff rate threshold can be adjusted with CV193.

      3.  Besides using Clock#1 with a three wire Massoth Pulse Generator/Hall Sensor, can the Clock #1 be used with a 2 wire chuff sensor?  Answer:  Yes!

      My comment:  The Massoth Installation and Configuration Manuals state to only use a Massoth Pulse Generator/Hall Sensor on Clock#1 which is a three wire unit.  Again, the Massoth German to English translations leave some room for improvement!

      I'll test using a two wire chuff sensor on Clock#1 with the Simulation Chuff turned off.  If it works well, then that's your solution.  So we don't need to worry about the double chuff caused by using Clock#2.

      Lesson Learned.......consult the decoder manufacture for technical guidance and hopefully they understand the customer's issue/problem/ this case they did not when Roger shipped the decoder to Massoth in Germany for assistance.

      My Track Cleaning Loco is the latest version, Red LGB/Marklin  The decoder is built in.

      i bought it new about 3 years ago. Interestingly the cleaning motor has always rotated the wheels in the same direction as the movement, not opposite as it is meant too. Easy to change but not necessary, it cleans well. 




      Andrew - I have both the Red version you have plus recently bought a used Yellow version with the onboard DCC decoder.......the last version of the Yellow one. 

      As already mentioned, you just switch the wires going to the cleaning motor.  It's easy to access that motor block as stated in your LGB Owner's Manual.  In fact, there's a reason LGB and LGB/Marklin designed the wheels to turn in the opposite direction........I believe it causes less grinding on your brass rails compared to the forward direction your loco's cleaning wheels are doing.  So suggest you switch those wires.

    • Dan,


      Working on it. getting some good photos and a bit of a tutorial. Probably be ready in a week or so once the kids activities settle a bit.

    • Thanks All.

      A quick update on my progress. After some fussing about, I realized the solution to my clear lenses was right in front of me! My wife makes Rhinestone shirts, and low and behold, clear rhinestones make perfect marker lenses and headlight lenses. Once you scrape the "reflective" or "glue" off the back, that makes them a bit scratched/frosted and a slight hit with 600 grit sand paper, makes the super bright LED's look perfect. A final bit of expanding of the factory holes in the U25, and I have replacement parts for the lenses.


      If anyone is curious it is 6.5mm clear rhinestones that fit like a glove. And to ream out the U25 marker light holes with 1/4 inch drill bit hand turned, not in a drill, to widen them a bit.


      Gilbert, Thanks for the info, let me take a look at your site.

      I may be able to help you with the other missing parts. I replicate the Aristocraft parts by 3D printing. If it is not already in my website listings, I would need an original to measure up to create the CAD file. The original can also be a mirror image or a broken part. 

      If you can ship me the original, the new part is sold to you for the price I will be listing it on my website. I absorb the cost of the product development by listing this new part on my website and selling many more to other railroaders. I return the original with the shipped order of the new part.

      There are over 100 parts in the listings for your Aristocraft engines and rolling stock. Sorry, not many fit on the U-25. My listings probably reflect the popularity and production numbers of the models issued originally by Aristocraft.

      Thank you for the support of guys like David Maynard and Father Fred Mills

    • When I added lenses to my C-16's class lights I wanted a frosted look. I used a paper punch to pop out circles from a yogurt cover. I imagine any clear plastic could be used along with a spray of UV protection.

    • GLX makes some Aristo parts, maybe Gilbert at GLX can help with certain parts. As for clear lenses, you should be able to come up with something for those.

    • Hi All,


      I know for the most part I am SOL, but hoping someone has a solution.


       I need the clear marker light lenses for the front/rear of the engine. Anyone have these or any idea how to make or repurpose something to make them? 


      Also need a few other parts for a Santa Fe red/silver Uboat. If anyone has one for parts in decent shape, would be open to purchase for what I need.


      Any help or ideas or direction is much appreciated.
