Factory resets on ALL TCS decoders are performed by programming?with a value of 2.?

NOTE:?Any TCS decoder manufactured on or after July 1st of 2019 supports the use of values of 2?or?8 in??to perform a factory reset.

Good afternoon Dan, Andrew,
So I have removed JMRI / DecoderPro from our test case.
I am using a Digitrax DCS240+ command station, a SoundTraxx PTB-100 programming track booster, a Digitrax UR93, and a Digitrax DT602D duplex/wireless throttle.
I attempted to do a "nuclear" reset by programming the CV's directly by using the throttle.
I am using my dedicated programming track. I set the throttle to use Direct Mode on programming track (Digitrax documentation says this is the preferred mode)
CV201 = 5, CV202 = 0, CV203 = 0, CV204 = 8
I did the nuclear test sequence and nothing.....No Nuclear Reset..I read back the DCC address and it did not change.
I would have expected it to have gone to 3. (Correct???)
What are your thoughts? Any ideas?

Originally you talked about the "Preset 1" now it is Nuclear Reset. Being upside down on the other side of the world, Nuclear Reset means something totally different.

I have attached a photo from a repair last week to show our Nuclear Reset.

Yesterday I tried one of my locos? save all its settings in Preset 1, then change some settings - then use Preset 1 to reset them. All setting came back as they should.

I then did a full reset (except speed table) - every thing went back to factory default including the number. I then used Preset 1 and all my settings were set back the way they were.

What is the date of the firmware in you decoder?

I hope the photo comes through!

I am confused - User Preset 1 Reset - a preset is when you store all your CV settings in Preset 1, Preset 2, Preset 3 or Preset 4. The idea of the assorted presets is to store different setting e.g. home layout, club layout or exhibition layout. It only takes a few second to reload - unlike Decoder Pro which would take a few minutes. In the early days, Decoder Pro was a "swear word" at TCS, this is back in 2014 - 2015 era.

Manuals - there are five of them to my knowledge each one is different but there is no way of working out which is the correct one for a particular decoder. I used to discuss all this with J.D. the bosses son who did most of the earlier programming.

What is the date of the firmware in your decoder? All my steam locos have WOW V4 decoders with different firmware dates - I will look for one that is close to yours.

A nuclear reset will change 100% of the configurations of the decoder. Due to time constraints in certain circumstances, a standard factory reset has been designed to ignore certain CV's and settings. The reset above will load User Preset 1, thereby overwriting everything. If no configurations were previously saved to User Preset 1, the decoder will be loaded will all default settings.

Tim,

I would like to say that the other users in this thread are trying to be helpful. They are fans of our products just as you are. Making a fuss and asking users to leave this discussion does not solve anything. Being impatient does not solve anything. I was out of the office for a business trip and I was unable to respond to any emails.?

Now a question I have is what version of a WOWSound decoder do you have? If it is Version 4.6, the 4 CV 'Nuclear Reset' will not work. This only applies to V4 decoders and older. The statement?If no configurations were previously saved to User Preset 1, the decoder will be loaded will all default settings.?This statement is 100% true. By loading in an empty preset (I've tested this with a fresh V4.6 decoder) it will load in all factory defaults for the decoder.?

Another thing I would like to point out is this statement underneath the 'Nuclear Reset' page on the Documentation Wiki:?NOTE:?This method of factory reset will not work in TCS Non-sound, or Version 5 WOWSound decoders. I did do this with an old V4 decoder that was lying around the shop. The 4 CV method did work it reset the decoder, except the DCC Address.

Since I'm guessing we are messing with V4.6 here this does not apply to the current situation.?

I hope this helps.
I apologize for the wait.

Good afternoon group,
#1.)
Please accept my apologies to this TCS users group especially to Carson and Gerry. Clearly I need to lower my frustration level and have more patience.!!
I was not aware that you were out of the office on a business trip.

#2.)
So I read CV7 and it said 4 which I believe means it is version 4.xxx. So how do I tell what sub-version number it is? Is there another CV for that?

The manufacturing date code is 05/14/2021 if that helps.

So I don't know how to tell if it is version 4.6 or not since I am unable to determine the sub version number. Maybe for the next version of the WOW-121 Steam decoder

you could add a way to read the sub version number.

#3.)
What is the very latest and greatest version of the TCS WOW-121 Steam Decoder? I will try to get those. I have 3 of those decoders.

#4.)
I would recommend that you add a note to the fact that a nuclear reset does not work for version 4.6 of your decoders to your tech support Wiki.

#5.)
Please note that I have NOT EVER saved anything into USER PRESET 1. I am using a TCS WOW-121 Steam Decoder. My goal IS to do a nuclear reset
and reset EVERYTHING back to factory default settings.
I am VERY confused by your response.........
In Paragraph 2 of your response you said.

If it is Version 4.6, the 4 CV 'Nuclear Reset' will not work.

Then near the end of paragraph 2 you said......

By loading in an empty preset (I've tested this with a fresh V4.6 decoder) it will load in all factory defaults for the decoder.?

So does it work or not???

#6.)
In Paragraph 3 you said

The 4 CV method did work it reset the decoder, except the DCC Address

So I am TRYING to do a nuclear reset (nothing saved in USER PRESET 1). So what I want to see is the ENTIRE decoder get reset to factory system defaults.
So how can I tell if it worked if it doesnt change the DCC address. That's what I was looking at to see if the nuclear reset worked or not!!
So what is a CV that I can change to what value and then try the nuclear reset. Then after that I can read back that CV and determine if the decoder got reset or not.
I would have expected a NUCLEAR reset to reset the DCC address back to 3 but you're saying that the DCC address does not get reset.
so could you please clarify your response for me (and others).

Thank you! Have a good day.
Tim


 

Tim,

Sorry for not jumping in on this. I have been out of the office for a week and am still catching up...

A TCS WOWSound "Nuclear Reset" is just a nickname I gave to the CV-programming-shortcut for "load User Preset 1"

Firstly - IF you have ever saved any data to User Preset 1, that data is being restored when you load the preset using this process. As an alternative, you can use a value of 8, 9 OR 10 in CV 204 and it will load User Preset 1, 2, or 3 respectively.

Second - Decoder Pro DOES program CV 201->204 in order properly when you "write full sheet" in decoder pro on the 4-CV programming pane. It is actually written on the pane itself HOW to use it. I use this feature frequently.

Third - Can you confirm the Manufacturer of the DCC Command Station you are using with Decoder Pro?

Fourth - You can accomplish the same goal using AUDIO ASSIST. 8888-4-2-2-3 is the button sequence for "load preset 1" If this process does not work, something is severely bungled. Make sure you load an unused User Preset, though.

Fifth - You can do a simple factory reset ON THE MAIN using CV 8 => 2 OR 8. DON'T use the programming track; then power cycle the decoder. There are strict timings on how long the decoder needs to finish a factory reset. If not given enough time, it will not reset and will instead stay as it is. Performing a reset on the main ensures the power never goes away and the reset is guaranteed to complete.

Okay guys.........I'm going to go through this again. This is at least the 10th time I've gone through this
so PLEASE read carefully and pay attention!! This will be the 32nd post for this topic and ZERO progress so yes I'm a bit frustrated.

I have a TCS WOW-121 Steam Decoder. I have that decoder mounted on a B-MB4 motherboard in my HO BLI Steam Locomotive.
CV7 which I believe indicates the version of the decoder is showing a 4 which means version 4.xxxx.
My understanding is that there is no way to determine the sub version ( .xxxx) of this decoder.
The date code is showing 05/14/21.

I have NEVER saved anything into USER PRESET 1. It is my understanding that a NUCLEAR reset will completely re-configure the ENTIRE decoder
using factory default settings since I have never saved anything into USER PRESET 1. Is this correct?
THIS IS EXACTLY WHAT I AM TRYING TO DO.

I am trying this nuclear reset on a dedicated programming track. i am using JMRI / DecoderPro.
I also tried to do this nuclear reset by setting the CVs directly using my throttle which would have eliminated a possible JMRI / DecoderPro problem.
Neither the DecoderPro method and the Throttle methods worked.

I am NOT getting any error messages from DecoderPro.

I am using ALL Digitrax equipment. I have a Digitrax DCS240+ command station and a Digitrax DT602D throttle (wireless / Duplex) and the UR93 wireless / duplex receiver,
I am setting the 4 CVs to the correct values in the correct order using the 4 CV Programming Pane. I have confirmed that DecoderPro is writing the correct CVs
with the correct values and in the correct order.

In an earlier post today Carson said that the Nuclear Reset does NOT work. His post was very confusing and didn't make any sense with his conflicting statements.
He also said that it is possible that the Nuclear Reset does NOT change the DCC address. I did not see this anywhere in the documentation wiki's, manuals, etc.
I would have thought that a Nuclear reset would have reset the DCC address to 3. Does it do this or NOT? I was looking at the DCC address in DecoderPro
to try to confirm that yes a nuclear reset has been done. If a nuclear reset does NOT change the DCC address then can you please give me another
CV that I can change to some value that DOES get modified by the nuclear reset. Then I can confirm if it worked or did nothing at all.

Writing a value of 8 to CV8 DID reset some (but NOT all) of the CVs in the decoder. But again my goal is I want a way to return ALL CVs / EVERYTHING
back to factory default settings.?

Thanks, have a good evening!
Tim

Hi Bill,

Yes I forgot to mention that I am using a SoundTraxx PTB-100 programming track booster and it seems to be working well.

I am able to read / write various CVs without any DecoderPro error messages.

Use the Audio Assist method I mentioned in my last post and not your Digitrax command station's programming track. Let me know if that works.

Thanks Dan........

I will try that this evening...........HOWEVER.......

I need to know a CV that I can write a value to, do the nuclear reset, and then read that same CV back to determine if the nuclear reset has done anything or not.

In a prior post Carson said that a nuclear reset might not change the DCC address, so I need to know a CV that I can write a value to,

perform the nuclear reset, and then read that same CV back to see if has been reset.

Thanks,
Tim


Tim Kelley
 

Hi Dan,
I have good news and bad news...........

Good news.....

I THINK I WAS able to successfully perform a NUCLEAR reset (USER PRESET 1) using the Audio Assist method. 8-8-8-8 4-2-2-3
The DCC address DID get reset to DCC address 3 so I would assume that the rest of the decoder DID get reset as well. (Although I have not confirmed this)
I have NEVER saved any settings into USER PRESET 1` so it should have loaded factory default settings.

Bad news.

It looks like trying to do a NUCLEAR reset via the writing of 4 CVs method does NOT work.
I did the following
CV201 = 5 / CV202 = 0 / CV203 = 0 / CV204 = 8
I tried doing this using JMRI / DecoderPro and it did NOT work.
I tried doing this directly using my throttle and that also did NOT work.

Can you please confirm on YOUR test bench that using the 4 CV method does NOT work?

Thanks, have a good day!
Tim


 

Hey Tim,

Went back and read through the thread, still confused, so let me ask, why do you want to do this particular reset? ??

jim


 

Tim,

I am not having any issues on this end when testing with an LT-50 current production decoders.

This form of decoder reset takes about 3-4 seconds to complete. If you are using a Digitrax programming track the reset will not finish before the system shuts off the power. "Always-on" programming tracks like the NCE PowerCab, LT-50, and a few others will not have an issue because they do not remove power between programming operations. You need to do the programming on the main, or the easier way through Audio Assist which gives you an audio cue when the reset/loading is complete.

Thanks Dan........
I'm using a Digitrax DCS240+ command station with a SoundTraxx PTB-100 programming track booster.
Yes I believe you are correct that the command station shuts power off to the programming track
pretty quickly when it thinks the CV write operation should have completed. I'll give it a try this evening with programming on the main and get back to you.
Thanks again.
