Sound Decoders are a specialized item made by a small group of companies (Soundtraxx, TCS, ESU/Loksound, etc...). Instead, they are constrained to certain ranges of functions. You would still call it ‘slow’ but you wouldn’t call it very slow. This is the "how long does the nurse leave the thermometer under your tongue?". SoundTraxx Tsunami Dynamic Brakes. JMRI is looking pretty good. Use 128 speed step mode for all tuning (and running?). BEMF decoders allow the 1 tie a minute type performance but it hard to like cvs for a basic sound starting point on the EQ ,I find the horn seams muted compared to the bell in default and I have a lot of issues trying to Quite that darn bell ! Think of it as the slope of the curve of the error. Consist functions have been disabled; set CVs 21 and 22 to enable functions for consist mode CV 209 is the Kp in the PID. Internet is the definition of slow speed is different between users. A PID controller is a well-known method of doing "process control". mfg id 101 - Bachmann sound decoders / Soundtraxx Tsunami try setting cv 8 to value of 8 tsunami can only program short address on program track to identify a decoder as a Tsunami - function 3 , is short whistle ===== mfg id 11 - NCE . Tsunami Technical Reference Page 5 CV 7 Manufacturer Version ID (Read Only) Description Contains 8-bit software version identifier. You will need to know who makes the decoder in your loco. Watch now to learn how to set the volume of every single sound effect in your decoders! I can get to them with my Lenz throttle, but it takes more keystrokes, so I re-map that sound function down to a lower key, like 6. Page 49 CV 132 sets the Air Compressor volume and may be set between 0 and 255. I occasionally enjoy using F4, for example, and that is a hissing sound. Let’s say that the target speed is 100, the current speed is 90. It takes an iron man to play with a toy iron horse. The GP50 used the new 16-cylinder 645F-series engine producing 3500 horsepower through the new AR-15 alternator. Even the type and size of speaker used has an influence on CV settings. Primary CVs Tsunami2 Steam Technical Reference 7 CV 2: Vstart Description CV 2 is used to set the voltage level applied to the motor at speed-step 1. Is'nt tsunami #3 default grade crossing ? Lightbulbs are burned-out. One of the most important aspects of a PID controller is the idea that it is not expected to achieve the "perfect" value on the first pass. It is rated at 22 volts and it will run there or higher but it doesn't much like it. To set the sound level for a particular effect, set the corresponding CV to any value between 0 (zero volume) and … I first set the address, then CV's 2,3, and 4 for motion control, although I have yet to get a Tsunami to alter its behaviour using CV2...I think I recall that it doesn't matter in Tsunami's. In our case the "process" is the speed of our Tsunami equipped locomotives. After that it will dump you into a manual push mode for blind programming. It includes knowledge I have gained recently in researching the PID process in general and the Tsunami decoders in particular. The other menu option is to press 2 for CV, then you can enter the CV … Kp is the ‘current error’ value. And the PID calculation (for simplicity of this example of how 212 works) is +10. Find SoundTraxx user guides, a DCC-Equipped Start Guide, technical references, and much more. It is a frequency in a number of milliseconds – if the value in 213 is 23 then it takes a measurement every 23 milliseconds. Enter a value from 8 to 13 into CV 8 to reset the desired CVs: 8=Full CV reset, 9=CVs 1-128, 10=CVs 129-256, 11=CVs 1.257-1.512. CV 213 is the specification of how often a BEMF measurement is taken. So, it gets reduced another 10 points at least. This note addresses some of the problems that have surfaced when using the new Tsunami sound ... CV-128 is the Master Volume Control and is set up by default at the value of 192 (75%). The Expectation is Tsunami should do the same but the actual performance can be lacking compared to what other decoders can do with BEMF. And, precisely due to this iterative nature – the formula that is a PID controller uses the history of the past corrections … in addition to the current measurements (in our case the BEMF value that is read during the "off" segments of the PWM. We feature beginner and advanced help on all model railroading scales, including layout track plans, model railroad product reviews, model train news, and model railroad forums. I intend to use this information in order to develop a procedure (or small set of procedures) that will allow you to find the best settings for the motor performance CVs - 209, 210, 212, 213, and 214 primarily … but also the BEMF cutoff, the momentum, and the trim CVs. Fall 2006 Vol. It is probably even a good idea to just do a decoder reset. Successfully managed 8 high volume product launches worth $65 million annual revenue on time ,cost and quality by precise planning and timely execution Launched $18 million annual revenue crash launch project Ford F150 brake pad in 4 months time due to supplier Tsunami crisis on time and cost with successful DV,PV and PPAP approval You need to know that the loco will perform well on its own. Media Converter SoundTraxx Tsunami TSU-AT1000 Application Note. And so on.... To get your loco to perform well at start-out and crawl speeds, you need to do an iterative procedure with the following CV's. To answer the original poster's question CV63 is the Master Volume and it has a range from 0-192. The Kd in the PID calculation represents the rate of change, over time, of the PID calculation. I spent quite some time on the phone with Soundtraxx today. D0-D7: Version Code 64 = Tsunami Steam Decoder, V1.0 65 = Tsunami Diesel Decoder, V1.0 This CV is read only and cannot be modified. If the value of 212 is 255 then 100% of that correction will be used. Others are not so picky. I take a start point near 50-60% of the range for that CV, but I don't automatically take one or the other. SoundTraxx has been providing Tsunami Digital Sound Decoders to Athearn Trains since 2009. Many of the tuning procedures ask you to do something until the locomotive start to move. The second phase is where the loco is moving but it may not be at a steady rate and it may not be "smooth". Locomotive runs in a consist, but without lighting or sound. get with the Tsunami. Which by the way is the main reason I use ESU decoders exclusively. and would like to share them with others ?? A loco with a train behind it may require more throttle in order to move at the same speed as it does light – and that’s a good thing and is a better simulation of an actual locomotive (and will sound better). Even the CV settings for two identical models, such as an Athearn RTR GP, are going to differ because of the different characteristics of the models. When you access CV 505 (when CV 32 = 2), the decoder will recognize it as CV 2.505 (DDE Side Rod Clank Low Volume Limit). The TSU 2200 has 6 function outputs, and a steam locomotive can realistically make use of ... Master Volume Level: CV 128 set to 192 out of 255 for 75% volume level. CV 64 (Master Brightness) has been set to a value of 0. No thanks. A value of 0 disables load compensation altogether while a value of 255 corresponds to full (100%) compensation. CV 212 is the "intensity" of the PID calculation that will be used. and setup of a SoundTraxx Tsunami 2 Steam Decoder (TSU 2200 Steam) into an IHC 2-8-2 Mikado Steam locomotive. After some adjusting of sound selections and levels the value of CV 128 chosen in my case is 60! The manufacturer of the sound decoders decide what sound goes to what button not NCE. Econami is for users seeking a versatile decoder ... What CV value do you use to increase the volume? Once I am happy with the horn and bell, then I normally reduce the other sounds from that set-point. By fisker76. The Tsunami supports both short (CV 1) and long (CV 17,18) addresses. You can't update or modify SoundTraxx decoders. If they come out with an update you have to buy a new decoder. Think of it as an ‘adjustment’ to the Kp – based upon what has happened the past few times the PID value has been computed. There is a master volume control, as well as sub controls for each sound effect. In program track mode press 1 for standard, if you get “cannot read CV”, press enter again, it will try a different read method, it also has a third one too. I take a start point near 50-60% of the range for that CV, but I don't automatically take one or the other. This is not "tie crawling" speed. Jerry. Think of this as the master volume control for BEMF. To re-enable access to CVs 1.257-1.512, re-enter a value of 1 into CV 32. Other Instead, you must fiddle with higher CV's that I will cover momentarily. Short addresses have a range of 1-127 while long addresses have a range of 0001-9,999. This can be increased to the maximum of 255. The basic CVs for motor and light control are going to be different for each type of model based on how each motor performs. If tinkering CVs don't do it,you may have to lift the shell to check the speaker and/or installation (no enclosure for instance). I did this with the J Class about two years ago and was amazed and gratified to find the J turning into a silk purse...it was incredible. The third phase is where the loco is definitely moving and is well above "tie crawling". Many DCC functions can be altered via Configuration Values (CV) utilizing the included chart; Detailed Information; Overview; In 1980, EMD released the GP50, one of the final models using the 645-model diesel engine. All CV values confirmed as read from NCE Programming track. conjunction with CV 2 (Vstart) and CV 6 (Vmid) to configure the 3-point speed table. ... Get SoundTraxx Support. CV 212 sets the amount of load compensation that is initially applied to the motor and may be set anywhere between 0 and 255. It is very hard for the PID controller to do its job – to provide smooth changes of speed and relatively constant RPM when the speed isn’t changing – if you only provide it with 28 steps (because each individual value represents a much larger percentage of the range of the throttle (think PWM). This is all I’m going to write up at this time. You do not need to set any Index CVs first. Soundtraxx set CV128=192 (75%) as default value for Tsunami decoders,wich you should have when resetting so you should still have some room left.SoundValue decoders may differ though. This week we are going to talk about the Volume Control CVs in Tsunami2 and Econami Digital Sound Decoders. 1. bell 2. horn/whistle 3.coupler on  & on. MR subscribers, check out the new All-Time Digital Archives. There is the first little bit of movement – it may even be a little lurch – but the loco does not move continuously and will spend more time stopped than moving. Rod clunk is hokey. Make sure you tackle this when your circumstances are such that you have a clear 30 minutes so that you can get some encouraging results...you don't want to stop and return a day later to find you have really botched everything and now need to do a factory reset....and losing all those other settings and the time it took to find them. CVs Used in This Video: CV 128: Master Volume CVs 129-160: Primary Mixer Volume Levels (129-150 in … The Tsunami also has a CV that determines if it will respond to a playable throttle at. Digital sound decoder for athearn rtr emd gp35 (6 pages) ... featured in Tsunami2. Soundtraxx-Tsunami and ESU are my preferred sound decoders. To the original poster, note you can adjust the volume of many of the sounds the locomotive produces, plus the master volume control (CV 128) will reduce the volume of all sounds. 133 Varies Dynamo Volume (0-255) 134 Varies Blower Volume (0-255) 135 Varies Rod Clank Volume (0-255) 136 Varies Steam Release Volume (0-255) 137 Coupler Volume (0-255) 138 Glad Hand Release Volue (0-255) 139 Brake Squeal Volume (0-255) 140 Brake Release Volume (0-255) 141 Snifter Valve Volume (0-255) 142 Power Reverse Volume (0-255) Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites. What does "starts moving" mean? It is highly unlikely that you will be successful in tuning the motor performance CVs correctly – if the locomotive wheels or the test track are not clean. See Audio Mixer for more details. Wiring: Standardizing Color and Connections, Runaway Technical Discussion (DC Bit Off), User Interface: DT40x vs ProCab Throttles, NCE DCC System Technical Spec Comparisons, Telco Using Ethernet/CAT Cable for Cab Bus/Loconet, http://www.mrdccu.com/curriculum/soundtraxx/tsunami.htm. Genesis HO scale locomotives and rolling stock are noted for their top-of-the-line features, finely nuanced detailing and prototypical sound. The following is a write up of what I was told. For most PID tuning procedures when it says "until it starts moving" we are talking about the 2nd phase. Primary CVs Bit … A PID controller is a well-known method of doing "process control". And also with the goal of changing from any current speed step to a new speed step … smoothly (a nice steady increase or decrease in speed that results in the operator seeing his train moving in a manner that approximates what happens on a real train. As the value of 212 is reduced the number of iterations of the PID correction process that are required to reach a given target from a given start/error point will take longer and longer. I like the QSI Titan version many times better. There's no set list of sound CVs because each different type of model requires different settings, and each person has their own preferences. The lamp wires are broken. Values between 20 and 40 are recommended. Radiator Fan Volume CV 134 sets the Radiator Fan sound volume and may be set between 0 and 255 as discussed under Audio Mixer. One of the confusions found out in the prime mover starts up and is very, very loud!!! Soundtraxx does not allow an active short address to be programmed. But don’t be surprised if you find you have to change one or more CV values – nor even if the settings for one are significantly different from those that ‘work’ in the other one. SoundTraxx Tsunami Articulated Steam Loco Chuff. The following is a write up of what I was told. It is also important to understand that the values for a particular locomotive – make and model and scale – may not work for other locomotive … and may not even work for a ‘sister’ locomotive (one that was produced in the same run of the same make and model). And the task we are working towards is producing a process/procedure that will allow the user to find/discover the best/correct settings for their particular locomotive that will give them the performance they want. CV 8: Manufacturer ID/Factory Reset CV 8 contains the NMRA-issued Manufacturer ID Code (141) assigned to SoundTraxx and it can reset CV settings to factory defaults. factory reset CV30 to value of 2 cv1= short address, default is 3 Instead, you must fiddle with higher CV's that I will cover momentarily. The 3-point speed table is active when bit 4 (STE) of CV 29 is set to 0 and CVs 2, 5, and 6 1. I would prefer to have it on function 3 like other sound decoders, but the design of the decoder doesn't let my arbitrarily re-map sounds. Ki is the integral error value – that is to say that it is the sum of the past few changes (corrections). Tsunami PID/BEMF CV Tuning Concepts. I have a old list from David Bedard (no meatballs) and he had a great generic EQ settings list and a fun list that gave a loco a "running like a prototype " (for fun) setting where it would take awhile to reach a faster speed and would take a while to bring it all to a stop ,Like I said, for fun ,not recommended ....Jerry. Next, I set the Master Volume CV for about what I can stand with all the sounds unaltered. innovator. Sooooo, if 212 has a value of 128 then the PID correction, this time around, would be +5. Think of it as the ‘base value’ (size) of the error (difference between the target and the actual). Press F4 and if I get a scale hiss as if I were about 60' away, that's what I want. All SoundTraxx decoders can be reset by entering a value of 8 into CV 8. Think of the PID calculation as a number. It includes knowledge I have gained recently in researching the PID process in general and the Tsunami decoders in particular. If you are planning to consist the model with other models equipped with SoundTraxx decoders (such as Tsunami or MC1 and MC2 DCC Mobile Decoders), make sure that the value entered in CV 215 is equal to the observed voltage of the track output from your command station, so that the reference voltage is identical to your other decoders. Yes, certainly if you have two sister locos and you have one of them running the way you like it then you should try the same settings (CVs) for this new one … and at least use them as a starting point. It should usually be a low number (25 and below). Tony's Trains is your source for diesel, electric & steam model locomotives, model train accessories & digital command control (DCC) online! 37 No. Okay, now follows a long document that I found authored by one Jim Betz. Take your time, read it at least three times over the next couple of days, and when you are good and ready, and have the I'm-not-kidding free time to complete the steps, have at it. It is how long the window is open. SoundTraxx Tsunami Grade Crossing Logic. The stock setting for master volume, CV 128, has a default setting of 192. If you purchased an Athearn locomotive released prior to 2017 it is equipped with SoundTraxx Tsunami Digital Sound Technology. Next, I set the Master Volume CV for about what I can stand with all the sounds unaltered. Locomotives should be tuned "light" (no train cars behind them). CV 214 is the duration of the BEMF ‘window’ (it is NOT the "D" in PID). After programming CV8 = 8, cycle power to the decoder (i.e. At that initial reduction of the Master Volume, I find the bell still much too loud for a person standing 100' away from the steamer rumbling down a yard track or approaching a passenger platform. An example will help. The Soundtraxx Tsunami is also somewhat limited by track voltage. So the "error" is –10. It should usually be a low number – and it will usually be a lower number than 209. ( it hurts my ears)  NOW I do use decoder pro and a stand alone PR3 and thought " I need my own default list " for starting CV adjustments ... the adjustments I would like to do rite from the get go or addressing ,would be, 1. move or jump at start up, I 'M still not clear on how to adjust this bad habit out where the decoder (loco) starts moving at start-up ,my QSI decoders start up at addressing but the loco does not move ,default, 2. raising the horn (diesel) and lowering the BELL, I take the horn CV to 240 and the bell CV down to under 100 and it (bell)still seams louder, though decoder pro seams to walk you though decoder set up , I was just wondering if others have a "go to list of adjustments " ? Soundtraxx Tsunami Hints II: December 5, 2005 Updated April 17, 2006. And yes, it … I spent quite some time on the phone with Soundtraxx today. turn decoder power off and then on again). This is, in general, a good thing. And when we are talking about this kind of thing there is an assumption that the decoders are also the same make and model. Some want 1 tie a minute type slow speed. The value for the "D" works the same way as the values for 209 and 210 … it is also a range/percent. It is an iterative process and will reach the targer (in our case target speed) after several successive corrections. It drives me crazy at full volume, and only somewhat better at 60%. On some of my decoders, the "coupler clash" sound defaults to one of the higher-order functions. This default volume level is astoundingly high! Thanks, Jim . If the value of 212 is 128 then 50% of the correction will be used. So, it is one of the first other sounds I reduce another 50% or so. OPS Mode Programming is write only for Soundtraxx Tsunami decoders. So if you feel the exhaust is too loud, but other sounds are OK, you might want to try adjusting CV 131, before adjusting CV 128. The idea is to "home in" on the correct value for the PWM – and then to keep adjusting the PWM in very tiny adjustments … all with the goal of having the motor turn at a constant RPM for a given speed setting. I try, often without any apparent success on my BLI J Class to reduce it to almost silent, but so far without success. There is a "D" in the Tsunami PID controller. Login, or register today to interact in our online community, comment on articles, receive our newsletter, I agree Mr B, I LIKE AND USE my coupler sound when hooking up and wish ALL manufactures would use the #3 button fore it ..ex. If you set the BEMF cut off level (CV 10) to a small value then the PID controller will be ‘in use’ over less of the entire speed range. ...oh well,I'll look it up..Jerry. Turn off all momentum (CVs 3 and 4) before starting. That number is actually a ‘correction’ for an error (the result of the PID calculation). Again the value of CV210 is not the actual value of the Ki but rather it is the percentage of the computed Ki that will be used to form the actual correction (final PID output calculation) to the PWM. High values above 200 may cause bucking of the motor. list of CV settings for your tsunami's that you would start with ? Let’s use an example from real life … this is "how often does the nurse take your temperature?". The address on your decoder can be changed on either the programming track (in some cases you will need a PTB-100 programming track booster available from SoundTraxx) or on the mainline. That said, QSI decoders can have their volumes adjusted, if that's what you are trying to program. With the default address of 03 and a 2-digit address is desired, a 4-digit address will first have to be programmed and then the final 2-digit address can be programmed. CV 2.503: DDE Load Offset CV 2.504: DDE Load Slope When the locomotive encounters a grade. Download Tsunami 2 Guide. CV 210 is the Ki in the PID. But the value of CV209 is a range from 1 to 255 – so what CV 209 really represents is a "percentage" of the Kp that will be used. Also note that most locomotive manufacturers do NOT make the decoders that are installed. Legacy of Leadership School of Education University of Michigan inn o v a t o r 37 : 1.
