MTH Wifi Unit can't find TIUs

I know this has been addressed before and in Barry's book, but I'm frustrated. I upgraded my TIUs & remotes to 6.0 with no problem. Now the wifi can't find my tiu.  Before the 6.0 upgrade, the wifi worked. I have uninstalled the app, reinstalled the app, unplugged and restarted the wifi unit. The wifi unit is set for MTH and TIU light is on steady, however the result is the same. No TIUs found.  Any suggestions

I posted a week or two back on this issue. My I phone always finds the TIU.  My Android  started  TIU not found so I bought a @$50, 7in android tablet an it worked fine for  a week then started the TIU  not found.  There has to be a system issue somewhere, in all cases the setup of TIU, Wifi , aux power and track power were not changed. Just turned off and on for run sessions.

Sound dumb, not trying to insult anyone but make sure the device bluetooth is connected to the proper device. 

just like using your wifi on the phone. Seen people struggle with this and they simply overlooked connecting the device and application.

I have exactly the same problem with all my ipads and phones, my system is new so I didn't have to do any upgrades so I cant comment if the problem is in the upgrade

I have taken lots of screenshot pictures of the fault and I am in touch with MTH tech department

When I get the solution I will post it

I have had the wifi working months ago when I first got it. Just back to running locos and can't get wifi working. I have it set to mth. I connect on my iPad to the mth network using the default mthdcswifi password but it won't add engines. Connection times out and I think said no tiu found. Tiu is powered by. Z4000 and I see red light. My handheld works fine, sees TIU and all engines. I have a new TIU do I need to perhaps update the wifi software?the wifi unit is lit showing tiu connection but the app software under settings says no tiu connection. Tried on iPhone and iPad. 

do I need to perhaps update the wifi software?

I expect so, for two reasons:

  • MTH says that you should.
  • You're having problems that no one should even attempt to resolve until you're using the recommended TIU software.

I appreciate that but it’s frustrating  why something would work and then stop for no reason. The Wi-Fi  worked fine at one time. The TIU is new so I thought that was current with software. Anyway I’ll check the TIU and Wi-Fi to make sure both are current- the l process to update the Wi-Fi seems a bit more complicated but let’s see. 

I have been working on my layout for the last two months. Just this last weekend I finally get  a loop put together to run the Polar Express along with other engines. My wifi setup couldn't find the TIU either. My wife's son happened to be over and asked if I was hooked up to the network. I amused it would do this automatically but as it turns out I have to go into my settings on my iPhone (this is where yours and everyone's else's router in the neighborhood is viewed) every time I boot the system and select the MTH network to find my TIU. After that, train life is good.

I'm surprised so many of your are having such a fundamental issue.  We need to get to the bottom of it and get things resolved for all of you.  There is no reason we know of for you to be experiencing this issue given the current version of firmware in your system.  So, let's start with that.  Please be sure your gear is updated to the following revisions:

  1. TIU -  v6.1
  2. WIU - v1.1
  3. App - v3.0.1

 

Once you are fully updated, if things still aren't working properly, reset each component.  I know it's a pain to reset the app if you have a lot of stuff loaded but, just export it and then import the image after the reset.  It's important to get your system to a point that is current and known.

TIU - Reset via the app or remote.  A feature reset should be adequate so you don't lose the TIU address.

WIU - Reset by holding down reset button (on top) for 10 seconds or more.

App - Reset by tapping "More > App Settings > App Reset"

There are some things you can try prior to the updates and reset that could be the issue but, given you guys are experienced, I doubt it.  Now, just because I said that, don't be embarrassed to come back and update us if it was a simple oversight.  I do it all the time.  The system is complex and has many elements.  It's really easy to miss a step.

Go to "More > App Settings" and make sure the app is set to DCS WIU.  (the latest version adds support for the Explorer and this setting may have gotten changed accidentally)

Go to "Settings > Wi-Fi" on your device and verify it is connected to the WIUs MTH network or your home network if you are in HOME mode.

Please report back here with your results.  Hopefully, we'll find the culprit in these steps but, have no doubt, the system is actually working fine and getting more and more stable with each app update.  We're working on a new update now with further enhancements .  It should be out in a couple of weeks.

Today, I switched all the hook ups to my second TIU, but wifi unit still reads No TIUs Found. Could my wifi unit have gone bad? I still need help.

In your case, 6.0 should be close enough.  So, if your other gear is up to date, try just resetting the WIU and cycle power on the TIU.  That is, power it down completely and then after resetting the WIU, power the TIU back up.  If you're connecting the WIU and TIU via USB cable remember TIU is powered by the USB so, unplug it as well.

I appreciate that but it’s frustrating  why something would work and then stop for no reason

What changed is that the app is a newer release than what you used previously.

One more thought.  There is a known bug wherein if you have multiple WIUs powered up but one of the connected TIUs is not powered up.  It causes timeouts and issues because the system doesn't get a response from the dead TIU.  

So, for testing purposes, make sure there is only one WIU powered up or, if there are multiple, be sure all TIUs  are powered up (red LED).

The update we're working on has this issue corrected.  In theory, user's wouldn't have WIUs powered without TIU power but, we ran into it here and so, we're modifying the app to ignore any unresponsive TIUs and just carry on with any that are alive. 

This is another example of how the system will keep improving.  If you kill all the weird corner cases and unusual bugs, the net result is a more robust and stable system.  We've not spent a lot of time polishing the premium app as we were busy developing the Explorer hardware and app.  So, now our attention is turned back on cleaning up some things on the power user side.

Firstly I must publicly thank Nicholas Jones of MTH who spent days with me trying to find the problem

We started by updating and resetting everything then removing all from track and adding engines one by one and testing, I got to 3 MTH engines to work then it failed again with the "no active TIU found" message, also TMCC engines failed to load same message. 

It did look like a problem with the handshaking between the WIU and the TIU because as previously stated the remotes were still working, it was just the WIU to TIU connection that was failing.

However here is the good news, as a last ditch effort this morning in order to minimize any problem with the connection between WIU and TIU I added a separate dedicated  power supply to the TIU via the  "power" socket

As of now all my TMCC and MTH engines are running

Well done Nicholas

I'm really glad you got your issue(s) worked out.  Thanks for your comments and I'll pass them on to Nicholas.  

Let me try to clarify some things that may have been contributing to your woes.  

First, if the TIU is connected to the WIU via USB then the TIU itself is powered however, the track may not be.  You cannot read engines on the track without track power.

If you power the TIU via fixed 1 input then, the track connected to fixed 1 only is powered.  In this case, there is no difference in terms of the TIU behavior.  Said differently, if you are having success powering the TIU with aux power then, powering the TIU using fixed 1 will produce the same results.  The TIU doesn't know the difference between these power sources.

Finally, TMCC engines cannot be "loaded" into the remote or app.  TMCC engines can only be communicated to and do not respond in any way.  There is no way for the system to load them or know if they are on the track or not.  The user must tell the remote or app that a TMCC engine is active.

Again, glad to hear things are working well now.  Even if the cause is unclear.  Maybe the track power supply you were using as input to fixed 1 has some noise or something.  What is the power supply you were using to power the TIU via fixed 1?  Is it operating on 50 Hz? 

Thanks for your thoughts, it could well be that the 50HZ 18V AC 10 amp supply to the TIU had some adverse effect on the TIU as you say cycles or even noise causing the TIU to lose its handshaking with the WIU, that might indeed be the case because it all works for the first few minutes of startup !  all I can say is that feeding the TIU directly with 18V DC has solved my problem.

( ps the input 1 and 2 are both permanently supplying power to the track hence my comment earlier that the remotes work fine, the TIU and the WIU were both powered up during the issues that I was having). 

It might be worth investigating in case some other overseas users are having issues with 50HZ, and unless its a fluke on my setup then the direct DC power to the TIU might solve it.

I understand your TMCC comment, my point was that I could not reconnect them because of the " no TIU found" message, but it works now !

Once again thanks for your efforts

Cheers and a Happy Holiday to all the OGR folks

For me I update the wifi software, I powered the TIU using three power sources, the wifi, the z-4000 in fixed one and another brick. The handheld works fine. The wifi tiu light blinks but the software says no tiu found. If I try to add engine it just times out obviously with no tiu found. I only have one wifi and one tiu  connected. I am connected to the mth router and I have tried reset a couple of times. Maybe just a bad wifi router?

Railmonkey,

What revision of TIU do you have? Are you using a USB cable or a USB to Serial adapter?

 A blinking TIU light on the WIU means the WIU can't connect to the TIU.

Something to also consider. The WIU can power the TIU via a USB connection but the WIU doesn't provide enough power to fully operate the TIU. You will want to make sure you have power to the FIXED 1 port or the AUX power port.

H1000

Its a new tiu region  version L how do I check the software version without a computer hookup? It's connected via USB and I have fixed 1 powered in addition to power to the aux power port. Only thing left I can possibly do is do an update to the tiu - I had already updated the handheld and a previous tiu so maybe something is out of sync assuming a new tiu has the latest version may be a wrong assumption 

Its a new tiu region  version L how do I check the software version without a computer hookup?

If you cannot see the app to see the TIU from the app, then you'll need to use a DCS Remote to learn the TIU's software version Menu/System/TIU Setup/TIU Version

assuming a new tiu has the latest version may be a wrong assumption 

It may well be that it has a version of software that's too old to work with a WIU. You should be using DCS 6.1, although it probably would find the TIU if using DCS 6.0. The Rev. L TIU's originally came with DCS 4.2, which would not connect with the WIU.

My handheld is 6.0, TIU is 6.1 and the app is 3.0.2 which just updated today. On my iPhone I got a tiu connection but would not add engines. On my iPad I still get no tiu connection. At various times I've reset the tiu and the wifi, tried three different power sources, two tiu' s and even swearing but no luck !

Wanted to do show and tell with the grandkids today but luckily the handheld works. I think I'll set this aside until someone else has an issue or a solution is found. I even tried another older serial tiu I have but that didn't connect either. Last thing that crossed my mind is if the wifi update took? 

Thanks for everyone's help tho

 

Firstly two things, have a lovely time with the grandchildren I am glad the handhelds work, secondly I am not trying to cut across all the advice that you have been given.

With the help of MTH I have been successful after 2 weeks of frustration, the advice I was given was to go back to basics 

1. ensure all devices are the current REV 

2. remove all devices from the layout taking power off the track

3. because it worked for me , power the TIU directly into the power socket on the side, I used a Lionel starter set power pack 18V DC ( I know MTH and others have said no need, but I am not convinced)

4. power up and make sure all the 3 lights on the WIU are on and steady, no flashing except the Wi-FI when it is connecting

5. put just one MTH engine on the track

6. power up and start the handheld app, you should be able to fined the engine and run it

Good luck
