I have been working my way through the steps to update the software in the TIU and Remote.  I have successfully updated two TIUs (early and rev L releases) with the help of several knowledgeable forum members (Note: the problem with updating my TIU got resolved when I did a power cycle on the TIU realizing that for the rev L the the USB provided power and unplugging the auxiliary power source did not interrupt the power AND when using the RS-232 interface one must ensure that the cable does not come undone at the TIU).

 

CURRENT PROBLEM: When trying to update the remote (version 2.10), I removed the stereo cable and connected the remote with a (4-wire) telephone handset cable.  I am using a USB cable and have the appropriate drivers from MTH installed on my computer.  An issue with the remote displaying messages on the screen while pressing and holding the power button got resolved after I purchased a second new handset cable.   Now when I start the MTH Loader program to upload a software update to the remote, the screen remains blank which I have been told by others is the way it should be.

 

When instructed by the loader app to press and hold the power button down, I do so fully and firmly.  However, within less than 2 seconds the Loader app asks me to release it, then 1 second later asks me to press and hold the button.  This cycle repeats (seemingly) indefinitely.  I never get to the point of benefiting from the use of a clamp.

 

I have attached a PDF file that has two screen shots of the Loader software display ("press and hold" and "release") and would very much appreciate someone who is familiar with the process to have a look at the screen shots and let me know if the content is normal, especially on the second screen shot ("release" the power button) which under status states "reconnecting to the remote via using TIU on COM3".

 

When the Loader app works properly, does it display a status bar with percent complete?

 

I really want to get back to working on my layout and running trains.

 

Thank much,

 

Tom

For the record,  should someone find this forum discussion in search to a solution to the problem described above:  basically, I missed an important warning made by Barry and Rayman4449.  I had the handset cord connected to the AIU INPUT rather than the REMOTE INPUT.  I was careful initially and had it set up right, but after discovering that I had a bad handset cord, I got sloppy and incorrectly plugged the new card into the wrong port.

Actually, I knew about the warning from MTH (and others) and paid careful attention to plugging the Remote Handset cord into the remote port.  But, I kept swapping things back and forth between two TIUs (early and rev L) and for some reason I mistakenly convinced myself that the handset was not fit into the AIU port.  Anyway, definitely my (embarrassingly) bad.

 

The good news is that both TIUs recognize the AIU so it would appear that I didn't damage either TIU (I don't have any accessories connected to the AIU yet for a final check).  And, the problem with my Variable channels not receiving power mysteriously went away and now that problem is behind me too.

 

I can now enjoy the hobby of running trains and completing my modest  garage layout.

IMO, it was somewhat of a bonehead move by MTH to use connectors that you could screw up like that.  They did a good job on the PS/2 boards, every connector is a different pin count.  It's a shame that thinking didn't carry over to the TIU.

 

Yes, I know that the AIU port is actually different, but you can stuff the handset cord into it and toast the port, so it's not "different" enough!

 

There is a mod for the TIU to prevent damage in the case of inserting the remote tether, I can't seem to lay my hands on it.  It requires surgery inside the TIU.

Come on John.  Bone head?  You can place the 7 pin connector on the 8 pin slot of PS-2 if you don't pay attention.  You can put the 2 pin battery on the 8 pin of a PS-2 5V if your not careful, especially on the side mounted Revs.

 

As with any wiring, you need to double check before applying power.

 

Mistakes happen.  G

John,

 

I'm with George on this one.

 

The connectors are different and MTH issues warnings before every DCS Loader Program process where the remote has to be plugged into the TIU. Further, the warning must be acknowledged, by clicking "OK", in order to proceed.

 

If someone is careless and doesn't pay attention, they suffer the consequences. Such is life. Those people are the "bone heads", not MTH.

IF a 7 pin versus 8 pin exact fitting is obvious how come a 4 pin small square versus a 6 pin large square on opposite sides of the TIU are not obvious?  It is not like they are side by side?   G

It might help if they were side by side.  Then you'd see two similar places to plug, and you might think more about it.  If you only spot one, some will just assume that's the socket and plug away.  If that weren't the case, we wouldn't be talking about it, and there also wouldn't have ever been a fix specifically developed to fix the AIU port when it gets toasted by plugging a remote into it.

 

Your analogy with the PS/2 boards isn't really all that germane, as most end users won't be opening up the locomotive and unplugging the electronics.  I have less empathy with someone that is working something that implies a certain level of expertise and then makes an obvious connector screw up.  However, the TIU was made for end user installation and configuration, IMO the connectors should be even more "idiot proof" than the internal electronic connections.

 

In any case, it's clear we'll have to agree to disagree as to the wisdom of the connector choice in this case, that's fine with me.

Wow Barry, I think I need to bump my post count just one more post.  I guess for some reason that silly member rating actually means something to you, I could really care less.

 

Your opinion is different than my opinion, yet somehow you feel that your opinion is right, and mine is wrong.  The mind boggles...

 

It must be really satisfying to know you're always right, at least in your mind.

 

You can have the last word, I'm done here.

Gentlemen,

    For you guys who work on this stuff all the time, things are easy because of your knowledge, however MTH could have set this up for the novice like Guns points out, with a completely different plug in type set up, completely eliminating any chance of mistake, making it idiot proof engineering.   My question is why didn't they make it fool proof from the beginning.  Heck I have had NASA engineers who do not read directions working for me, from time to time, it should have been made idiot proof from the beginning, this is toy train technology for the masses, fool proof it.

Dave - I am a retired aerospace engineer and agree with your perspective.  I love what MTH has done for the hobby and I used to be an MTH dealer and advocate through my wife's store (Artisans' Depot, later  renamed to the Village Depot) until we sold it in 2001.

 

My mistake (plugging the Remote into the AIU port) happened after I had removed a TIU from my layout so I could get off my back under the layout and have more light.  I was very careful with the connections as I was trying to program two TIUs.  When one didn't work, I would switch to the other and even rotate the TIUs once ... got sloppy along the way. In the future, if I remove the TIU from the layout for reprogramming, I will place "painters tape" over the AIU port.  While the TIU is installed in my layout, I have a USB and handset attached to the correct ports and will attempt to reprogram while it's in place.

 

I would recommend to MTH that they consider:

 

(1) adding some error detection logic with messages or warnings (perhaps in the Loader software) would make it more fool proof for impatient types like me

 

(2) tweaking the design so that power cycle resets are no longer required or having the ability to do this with a button on the side of the TIU or through the remote control.  It took me awhile to discover that the USB cable provides power to the TIU.   I kept removing and reinstalling the auxiliary power thinking that I was effecting a TIU power cycle but of course it did not and the Loader software would never have found the TIU.  

 

Barry,

 

Didn't see a "post above" saying that this was already in place, but I probably missed it like the AIU port warning ROTFLMAO.  

 

But, to clarify my suggestion:

A warning saying "REMOTE NOT FOUND!!!!  Please ensure that (1) the remote is connected to the Remote Port and not the AIU Port and (2) that you are using a WORKING 4-wire telephone handset cable and try again" would be welcome.  The software lets the user know when it can't find a TIU.  Not sure the Loader software suggests power cycling the TIU - if not, it should.  And, it should advise for Rev L to disconnect/reconnect the USB cable to recycle power (while having the aux power cable disconnected during the upload process).

Tom,

A warning saying "REMOTE NOT FOUND!!!!  Please ensure that (1) the remote is connected to the Remote Port and not the AIU Port and (2) that you are using a WORKING 4-wire telephone handset cable and try again" would be welcome.

First of all, there is a message displayed when the remote cannot be found, as you well know.

 

Second, if the TIU looks for the remote and it's already been erroneously plugged into the AIU port instead, the damage may already have occurred. That's why the message is issued before the TIU attempts to look for a remote, rather than after.

The software lets the user know when it can't find a TIU.  Not sure the Loader software suggests power cycling the TIU - if not, it should.

Actually, the Loader Program does issue a message after every upgrade or backup/restore operation that states that the TIU should be power-cycled.

 

The only thing that isn't explicitly stated is that the computer's connection to a Rev. L TIU's USB port does, indeed, provide power for the TIU itself, and for DCS Remote and TIU software upgrades, and DCS Remote backup/restore.

Tom,

There was no message displayed that the remote could not be found as I well know as I was there.  

You're correct as to the wording of the message not naming the remote, however, there are messages issued.

 

In one case, the Loader Program will issue a message stating that the TIU cannot be found, even though the remote is what's actually "missing".

 

In the other case, you get a pretty good hint when the Loader Program keeps telling you to hold in, and then release, the remote's power button. That can get old pretty quick!  

I have the same problem where I have updated the TIU from version 4 to version 6.10 but, I can not update the remote.

The remote is at version 4 currently, everything is plugged in correctly and I get the alternating message of "hold power button", "release power button".

I'm going to try a different phone cord when I find one, and search for how to reset the remote to factory before trying again. Any other suggestions?

It does not state that I need the stereo cable plugged in the TIU while doing this, and I have tried both ways to no avail. Any help is appreciated. I don't feel like buying a WIU yet.

The real question I ask when I read threads like this is why any newbie to DCS would ever want to buy it! :-) Just when I move an inch towards maybe trying to upgrade from DCS Explorer (which works beautifully, BTW. And the app updates automatically, and so far there has been no requirement to upgrade firmware), a post like this makes me rethink spending hundreds of dollars and buying Barry's very informative book, and sticking with the simplicity of what I've got. 

I really admire you guys who venture into this world and have the stamina to stick with it and make it all work. I am increasingly convinced that I'd wind up with a pile of hardware that I'd hopelessly screw up!

 

Thank you RJR. I'll borrow a few phone cords from work tonight and make sure I press the button firmly. I did notice it required a TIU power down to retry again and again. I'll also eliminate the stereo cord from the equation. Thanks!

PDXTRAINS. The stuff I have is getting on in age. It is quality stuff and will run for a long time to come, but it does come with these little obstacles if you want to bring it up to speed with the latest tech. I could have left my setup at version 4.0, but I'm going to upgrade to a Wi-Fi setup sooner or later and had time to try today. 

Thanks again RJR!

And just like that I'm up and running version 6.10 on the remote and the TIU. The problem was a sub-par phone cord. As a side note, I set up my trains and ran them while the TIU was at version 6.1 and the remote was still at 4.0. Everything worked fine.

Again to PDXTRAINS; Don't hesitate a second to upgrade to new tech, or even buy the older stuff. These guys at MTH got the best setup around in my opinion, and with the knowledge base you have here and  enthusiasts / technicians around the country, there are very few problems that will keep you from running your trains.
