Hi all I have a new Athearn Genesis GP7. It is set from teh factory to have the sound come on whenever the decoder gets power. Annoying . Hoe do I change the decoder so that sound comes on either with F8 or wit's speed step 1?
Gary
Since it is probably a Tsunami sound decoder, you will need to adjsut CV114. This value affects the prime move notching as well so be careful. This is from the Tsunami 2 manual.
CV 114: Adjust Auto-Notching Sensitivity Add a value from 1 to 15 to CV 114 to adjust the number of speed steps within each engine RPM notch from 1 to 15. Auto-notching is set to 7 by default, but we recommend a value of 15 when DDE is enabled. You may use the RPM+ (F5 by default) and RPM- (F6 by default) functions to manually adjust the engine RPM notch level during operation when auto-notching is enabled.
CV 114: Enable Manual Notching Set the auto-notching sensitivity level to 0 to enable manual notching and disable auto-notching. When manual notching is enabled, the engine RPM notch level will not be automatically adjusted in response to the throttle setting, and you must use the RPM+ and RPM- functions to adjust the engine RPM notch level during operation. Manual notching is intended for simulating the prototypical operation of a diesel locomotive and allows you to change the engine RPM notch level when most appropriate. Manual notching is disabled by default.
CV 114: Enable Engine Interlock Add a value of 16 to CV 114 to enable engine interlock. When engine interlock is enabled, you must turn on the RPM+ function to start the prime mover before setting the locomotive into motion. Similarly, you will be unable to turn off the prime mover during movement. In other words, the locomotive must be stopped before you start or shut down the prime mover. Engine interlock is disabled by default.
CV 114: Enable Auto-Start Add a value of 32 to CV 114 to allow the prime mover to start when the decoder receives track power. For DCC operation, the prime mover will not start when the decoder receives track power when auto-start is disabled. For analog mode (DC) operation, the prime mover will start when the decoder receives track power regardless of CV 114. Auto-start is enabled by default.
CV 112: Sound Configuration 1 0 = E-stop idle and alarm bell disabled 1 = E-stop idle enabled (default) 2 = Alarm bell enabled 3 = E-stop idle and alarm bell enabled Auto-Notching Sensitivity CV 114 + 0 = Auto-notching disabled CV 114 + 1 = 1 speed step CV 114 + 2 = 2 speed steps ↓ CV 114 + 15 = 15 speed steps Basic Programming Tsunami2 Diesel User’s Guide 36 CV 114: Select Dynamic Braking Modes Selecting a dynamic braking mode will allow the decoder to set the engine RPM to a designated notch level when you turn on the dynamic brake function (F4 by default). Dynamic braking modes are disabled by default. Add a value of 64 to CV 114 to allow the decoder to set engine RPM to notch 1 (idle) when you turn on the dynamic brake function. Add a value of 128 to CV 114 to allow the decoder to set engine RPM to notch 4 when you turn on the dynamic brake function. Add a value of 192 to CV 114 to allow the decoder to set engine RPM to notch 8 when you turn on the dynamic brake function. Note: The dynamic brake function will override the Dynamic Digital Exhaust RPM setting when a dynamic braking mode is enabled in CV 114. The HEP mode function and emergency stop button will override the RPM setting of the dynamic braking mode when the dynamic brake function is turned on.
I hope this helps.

Short version, assuming nothing has been changed from the default, read CV114, subtract 16, and put that value back in CV114. Now you have to hit the RPM+ function button to start the engine after power up.

Wouldn't you subtract 32 ?

It depends on what the OP wants to do. If he wants the press F5 (assuming default mapping) to start prime mover you would subtract 16. To have it start with speed step 1 would be to subtract 32.
Personally I use JMRI and take the math out of it. Makes program way easier.
Glad you posted this!
I was lost after the 1st paragraph of the previous post. That guy knows allot more than me about programming these decoders And his reply is probably easily understood by you and other more advanced DCC users. I read some of that in the manual and thats WHY I posted here hoping for an English interpretation.
Is the RPM+ function button the throttle wheel on the NCE Pro cab?
Ok so I want to subtract 32 so sound starts when I apply speed step 1.
I want to subtract 16 if I want sound to start when I push the Function 5 button on the controller.
Correct?
Yes.
For everyone else - the instructiosn say add 32 for automatic startup, or add 16 for startup on F5. They also say the "add 32" is the default. So I want 16, not 32 - that means I subtract 16. Or if you really must do it in 2 steps, subtract 32 to turn off that option, then add 16 to turn on the F5 startup option.
And remember they are always talking about the base value of the CV. You don't just blindly add 32. You need to read the current value. If it is already 32 or higher, the option is on adn you can;t add another 32 to the total.
Again, this is just like CV29. Pick the value for each option you want, add them up and that's how you get the total to plug in to the CV. It ISN'T hard, don't overthink it.
ANd - why do you want this one to NOT start up when you turn on the power but you want the other loco with a loksound to come up as soon as you turn on the power?
ANd the absolute most silly option is the one where the prime mover doesn;t start until speed step 1 - why Soundtraxx even offers that is a mystery. Looks really silly to see a loco start creeping down the track and then the prime mover cranks up. IS it a hybrid loco, running on batteries and then the prime mover kicks in? Either power on with the track power or start with a function.
Thanks Randy.
I don't want any locos to just come on when the system power is turned on or there would be a bunch of them starting up and idling even if they are not in use. I agree with your point that there should be a function key to start the prime mover and not a speed step.
As always you make the information clear and understandable. Thanks.
I read CV114 and subtracted 16 but it still ones on with layout power. Does this decoder need to be programmed, shut of and then re-energized to take the settings?
Dunno but all you would have to do is tilt the loco to one side so the wheels on one side break contact with the rail.

I'll try that
Tsunami has several decoder versions and associated manuals. This loco was purchased new a few months ago. How can i tell which decoder is in it?
Ok found it on the Athearn site, it's a Tsunami 2. The manual says:
CV 114: Enable Engine Interlock
Add a value of 16 to CV 114 to enable engine interlock. When engine interlock is enabled, you must turn on the RPM+ function to start the prime mover before setting the locomotive into motion. Similarly, you will be unable to turn off the prime mover during movement. In other words, the locomotive must be stopped before you start or shut down the prime mover. Engine interlock is disabled by default
So I subtracted 16 from the default value. Is this what you were talking about the manual being wrong?
When I get home later I will post the original value and the value after I subtracted 16. See if it looks correct.
That says nothing different that the previous information about adding 32 or adding 16.
I get that ordinary people may understand the idea of adding 16 or some number, but you can't blindly do this without knowing the starting point. As I explained in the other thread, adding values like 4, 16, 32, etc. are just turning certain bits on. If it's already on, adding another 16 would change a completely different bit. According to the original information, the bit controlled by the value of 32 is already on as the default. You don't want auto startup but you do want the interlock as controlled by the 16 value. Adding 16 to the default value would turn on BOTH bits - who knows with these things, maybe that's what it wants. Subtracting 16 turns OFF the bit for 32 and turns ON the bit controlled by 16. Subtracting 32 from the default turns off the bit controlled by 32 and makes no other change. Adding 16 after that then sets the bit controlled by 16 on. SO - same thing as just subtracting 16 in the first place.
What really matters is exactly what combination is required. The instructions orignally posted suggest that the 16 and 32 bits are mutually exclusive - you want one or the other. However, if subtracting 16 did not give the desired result - either the original value was less than 32, OR the actual setup required is both bits need to be set.
Ok so the CV 114 value that was programmed into the locomotive when I got it was a value of 103. I subtracted 16 which made it 87. The sound still comes on when the layout is powered up.
gdelmoro Ok so the CV 114 value that was programmed into the locomotive when I got it was a value of 103. I subtracted 16 which made it 87. The sound still comes on when the layout is powered up.
Please correct me if I'm wrong but if the default value of CV 114 is 103 and the interlock feature is OFF by default then you shouldn't you ADD 16 to this value to give a value of 119 to turn on the feature?
Joe
A vaue of 103 has auto-start turned on. So to get rid of that, subtract 32. Then add 16 to turn on the notch+ startup. So, same thing as just subtracting 16.
Now, if the instructions are misleading, as I mentioned in my last post, you can try adding 16 and making it 119. That per the documentation would have both auto start and the manual start on, which would seem to be contradictory. But what do I know, there are reasons I won't use Tsunamis...
Renegade1c CV 114: Enable Auto-Start Add a value of 32 to CV 114 to allow the prime mover to start when the decoder receives track power. For DCC operation, the prime mover will not start when the decoder receives track power when auto-start is disabled. For analog mode (DC) operation, the prime mover will start when the decoder receives track power regardless of CV 114. Auto-start is enabled by default. I hope this helps.
Well turns out that OEM decoders use a different CV than their other decoders. Its actually CV116 for OEM decoders not 114.
this is from User Guide found here. on page 44.
Engine Auto-Start
When active, the Auto-Start feature starts up the prime mover sound automatically whenever the decoder is powered up regardless of whether or not it is addressed by the user. In this manner, the locomotive will begin producing sound without any user intervention. To use the Auto-Start feature, first determine the baseline value for CV 116 based on your choice of manual (setting of 0 or 16) or automatic engine notching (settings 1 through 15). Then to enable auto-start, add 32 to the setting in CV 116.
Example: We want to use automatic notching with a one notch increase for every eight speed steps. From the section under ‘Engine Control’, we determine the base setting for CV 116 to be 8. Then to enable Auto-Start, we add 32. Thus, CV 116 is set to: CV 116 = 8 + 32 = 40. Set the CV to something between 1 and 15 and the primer mover should
So if you set CV 116 to a value between 1 and 15 it should not start up until you select the locomotive. So typically 1 notch for every 7 steps is pretty normal for me. So if you set CV 116 to value a of 7 you should get automatic notching engaged and prime mover shouldn't engage until you select it.

So this whole thread was based on #FAKEInstructions, who woulda thunk?
Holy Mackrel Andy! I was wondering why the manual said CV114 was for the bell .
Ok let me try CV116+7
BTW what is OEM?
Original Equipment Manufacturer

Not based on #FAKEInstructions but the wrong instructions.
Confusion has been created by applying Tsunami2 instructions to a Tsunami decoder.
Fact - Tsunami2 instructions cannot be use for a Tsunami decoder and vice versa.
The decoder factory installed in the Athearn Genesis GP7 currently in the market is a SoundTraxx Athearn Genesis OEM Tsunami decoder. The next release of the Athearn Genesis GP7 scheduled for May 2018 that use SoundTraxx will contain a SoundTraxx Athearn OEM Tsunami2 decoder per Athearn.
RR Baron
Original Equipment Manufacturer, which means 2 things, Athearn puts Tsunami boards in Athearn locos, in this case, and Tsunami also sells their boards through retail outlets.
Your computer has a hard drive. Let's suppose it is a Dell and it has a Western Digital hard drive. You can find on Ebay, an OEM hard disk that is made by Western Dig that is exactly the same. You can also buy Western Digital hard drives, which will also work, but maybe bigger or smaller, faster or slower than the original in your computer.
Back to decoders. They maybe the same as a retail version, but more probably they differ in certain specifications. In this case which CV's do a certain function. The Bachmann sound value decoders always turn on with power, for example.
I have a Bachmann 2-10-0 with a Sound Value decoder that I was able to set so it doesn't start making sound until I enter the engine address. Not sure how I did it now. I have some other Tsunami-equipped engines where I dial in the ID number then have to momentarily advance the throttle to get sound to start.
Tsunamis in general are pretty complicated to set up. There are other sound decoders that are easier to adjust regarding sound start-up, I believe Lok-sound decoders default is to not make sound until you hit a 'start up' function button.

So what is the correct CV for the Soundtraxx Tsunami decoder? I looked at the diesel sound manual ant it says it's CV113 (Pg47). the CV116 did not work Nor did the CV114. CV113 set to 150 worked the first try, then I turned power off and then on again and the loco started up. When I tilted it and pit it back down it was silent until I hit a function key. I could repeat this consistently but layout power off and then on again starts sound up.
Using the Quiet Mode
Tsunami’s Quiet Mode is used to turn the sound on only after the decoder is placed into service. It will also automatically turn the sound effects off when the decoder is not being used. This is particularly useful when you have a large number of sound equipped engines on your layout and don’t wish to have them turn all at once!
To activate the Quiet Mode, simply program CV 113 to any non-zero value between 1 and 255. This value sets the amount of time in tenth second increments, that the decoder will wait before it turns the audio off. Thus, a setting of 120 corresponds to 12.0 seconds.
When the Quiet Mode is active, the decoder will remain quiet when it is rst powered up and then automatically turn on the audio whenever it receives a non-zero speed command or any function is turned on (except Mute). It will automatically mute the audio when the locomotive speed is returned to zero, all functions are turned off and the time set in CV 113 has elapsed.
Setting CV 113 to 0 disables this feature and the sounds will turn on immediately when the decoder is powered up and remain turned on for the duration of the operating session.
wjstix I have a Bachmann 2-10-0 with a Sound Value decoder that I was able to set so it doesn't start making sound until I enter the engine address. Not sure how I did it now. . . .

An aside
wjstix,
You set CV 113 Quiet Mode Timeout Period.
A Bachmann HO USRA 2-10-0 Decapod factory equipped with sound is equipped with a SoundTraxx Bachmann OEM Tsunami decoder not a SoundTraxx Bachmann OEM Sound Value decoder. The Tsunami and Sound Value are different SoundTraxx family of decoders.
BTW, Sound Value does not support CV 113.
Not sure how Bachmann got into the mix. I have an Athearn Genesis GP7 purchased new several months ago from Model Train Stuff. As I understand the posts and replies it has a Soundtraxx decoder.
I'm still unable to get it to stay quiet until I select the loco or a function key.
Tried to call Athearn Tech Support but their website number does not work for Tech Support. Guess I'll try Tsunami.

Yeah I screwed up thats why I posted a correction. I realized after my initial post that I looked at the regular user guide and not the one directly associated with the GP-7 in question.
I will play with one of my Tsunami's at home and see if i can you a value you need to disable this feature.
