Earl, please rename this thread.

Progress Report

The problem with Rev. G Variable Channel #1 operation has been corrected. MTH, I and other beta testers have verified that the bug, indeed, has been slain.

The problem had to do with debug code in the TIU software that was set to sense if a port line had voltage present at Variable 1. Based on the particular port, this would only occur on Rev. G TIUs.

At this time, MTH is working on correcting a few additional, more obscure issues in 4.0 and expects to have a new release available as early as next week.

Earl, I'd appreciate it if you would change the name of this thread to "TIU Rev. G Variable 1 Issue Corrected in Beta". That should alert most interested parties to review the latest posts.

Thanks!

Original Post:

Does anyone know of the status of DCS Rev 4.0 revisions to make it compatable with the Rev 'G'/Var 1 channel? Has the problem been duplicated at MTH? Is any software revision in Beta test? Is MTH, for sure, going to correct the problem?

Folks,

I am wondering if I should call MTH Service on Monday and report my Rev G/Var 1 upgrade outage, "RGV10", or just wait and see if MTH releases new software.

Craig,

Don't call MTH. When there's a fix you'll hear about it on the forum. Right now, there's nothing at all that can be done to correct the problem. MTH Development is working on a solution.

Thank You webmaster!

Barry,I know you and others beta test the software they give you so my question is when they make new upgrade software don't they test all current and past tiu releases for possible glitches just curious would appreciate any insight on this I have never done my own upgrade to tiu etc and am going to wait till things level out or may not as I prefer to use the cab-1 or 2 remote I have big hands and the current cab2 is a one hander for me no problem and use other hand to run dcs. is there anything new in 4.0 that enhances the operation of locos that don't have quilling whistle and other new features if not then no sense to me for upgrading as more into working to finish layout than buying more locos and cars. hope you all have a nice warm day. $oo

Yes, we and MTH do a considerable amount of regression testing. The problem here is that this issue crept in surfaced mid-way through beta testing. However, since I was the only one reporting the problem and MTH could not replicate it (not all TIUs have the problem or in the same form), I chalked it up to a bad TIU channel on my venerable never-been-repaired-or-upgraded Rev. G TIU.

Actaully you mentioned the problem to me and I could replicate it and we both reported to Jason (who couldn't seem to replicateit). You, having a non repaired TIU, and I, having a repaired TIU (yes folks, both Rev G)

I also have an original, pre-ordered before they were on the market, TIU. What do you mean repaired TIU. I have never had my TIU in for any repairs. Was there a problem with the TIU that should have been sent in for repair?

Thanks
Tracy

Mine is a repaired Rev G too.

If it fails it needs to be repaired, yours obviously has not failed.

Is the failure the var 1 channel? And what is the cost of repair? For my future reference.

Tracy

After the advent of the Rev. H TIUs, whenever a Rev. G TIU went back to MTH for any kind of repair it was automatically upgraded with some of the Rev. H engineering, e.g., heavier traces, signal generator improvements, etc. However, fuses were not added.

Not the one mentioned with DCS 4.0, but any channel in general. As it so happened, Mine lost the DCS signal on VAR1 and about a week later on VAR2. As long as yours is working, you need not worry.

Thanks for the info.

I can not speak for MTH; however, I would anticipate that because the issue surfaced in the middle of the 4.0 beta testing and it did not happen before on mine and other's units under 3.11, that it will be another software download of DCS 4.x at some point which under MTH policy is free.

I wonder if their might be a problem with Var 2 also. My Var 2 failed when I had DCS 3.10 in the TIU and 4.0 in the remote. The voltage dropped from 18v on the input to 12v on the output on Var 2. I was unable to get the voltage up by dialing up the voltage on the remote or putting the Var 2 in Fixed mode. I chalked the problem up to the oddball DCS 3.10/4.0 that I was operating with and did not report it on this forum. After using Barry's advice to do the resets before and after the DCS 4.0 upload, my system is working fine on Fixed 1 and Var 2. I am not using Fixed 2 and Var 1 is still inop.

Is anyone else having problems on Var 2 with DCS 4.0? It would be good to get all DCS 4.0 problems defined so that MTH can fix them in one upgrade.

People, stop confusing the current issue that DCS 4.0 has with var1 Rev G TIU's and those of us that have had our Rev G TIU's repaired in the past. They have nothing to do with each other.

Earl, My TIU repair was back in 2003, long beofre even DCS 3.0 was out, and actually before 2.21 was out. It had nothing to do with DCS 4.0. And, there is no reason to mix software revisions between the TIU and remote.

Winrose, the repair issue we are discussing has nothing to do with DCS 4.0.

Rod, the reason I had DCS 4.0 in the remote and 3.10 in the TIU was because my Var 1 channel was not working. That was before we knew that there was an issue with the Rev 'G' TIU and DCS 4.o on Var 1. I reinstalled 3.10 in the TIU to see if I could regain control of Var 1. Barry then advised me to do some resets and reinstall DCS 4.0 in the TIU. I followed his advice and Var 1 worked OK for about an hour and then started acting strangely. I eventually abandoned the Var 1 channel by moving the connections to Fixed 1 which I am still using.

Earl

I know the repairs to the TIU I asked about do not have anything to do with the software. I was inquiring if there were some hardware issues I was not aware of and if I should have sent my TIU in for the hardware upgrades.

I know know if the TIU fails and not because of the V4.0 upgrade I should send it in and MTH will repair it and upgrade it as Barry mentioned.

I am holding off installing V4.0 until the TIU V "G" issue is solved.

Hope I didn't start the confusion in this thread, just saw something I did not fully understand and figured I ask.

Thanks for explaining it to me.

Thankyou
Tracy

What is the problem involving Rev 4.0 software and Rev G Tiu's?

Al

It has been reported on the forum by some, myself included, that after upgrading to DCS V4 on a REV G TIU that the variable 1 channel would not raise the voltage when in the variable mode or have little or no DCS signal in fixed. It doesn't seem to be affecting everyone with Rev Gs. All other outputs seem to work fine.

Barry has reported that MTH is aware of this and working on a solution.

Rod for me, my TIU G repaired in Dec, lost the "watchdog" signal on Variable 1 once I loaded DCS 4.0 this past weekend. It worked properly on 3.11 and when I addressed it with Barry he indicated in his email that it started around midway in the beta testing (Dec).

How did you determine that the "watchdog" signal was lost?

Winrose, my point is that people are confusing the improvements that MTH made to the Rev G TIU's when they were returned for repair with that having anything to do with the Rev G Var1 problem DCS 4.0 has. This is NOT the case. DCS 4.0 has issue with the Rev G TIU Var1 regardless of whether or not the TIU has been repaired.

That should be evident to those that have read every word that has to do with this situation on this forum, Barry himself has stated the TIU he had issues with HAD NOT been repaired, and I have stated that mine HAS BEEN repaired (with Rev H improvements less the fuses). Understand?

I'd like to clarify that this wasn't so in my case and I suppose it could be the same way today.

My Rev G TIU went south well after the Rev H TIU's had been released. It was repaired under warranty, but there were no mods made to the TIU, I took photos of the before and after repair.
The second time my TIU went south, MTH did in fact install the upgrades, as it was quite evident when compared to the previous photos..
