Remotes suddenly not recognized by TIU

Have you tried to tether the remote with a 4 wire handset cord?

If it will find the TIU when tethered (press read) and doesn't work when unplugged, the transceiver board inside the remote probably became dislodged.

Thank you Engineer Joe,

I just tried each remote tethered to the TIU and got the message ,”TIU error”

"TIU ERROR" often indicates that the TIU number in the remote is different from the actual TIU number.This would only affect remote operation and not using the DCS Application.

When you power on the TIU, note how many times the red LED blinks before coming on steady. That's the TIU's ID#.

Then, press READ on the and note what TIU isn't found. That would be the TIU number that's in the remote. If the two ID#'s are different, that's the source of your problem.h

Thanks for your response, Barry. This is where I am so far. The following applies to BOTH remotes:

Batteries have been changed.

Doing a read, tethered, we get the “ tiu 1 not found” message.

The Tiu (I only have one) blinks 3x, the remotes have been set to 3 and then  to 1, neither finds the tiu and I cannot set the tiu address from the remote because it can’t be found.

I can still run trains through Wi-Fi.

Any further thoughts?

If the TIU still blinks 3 times after you think that you set the remote to "1", you did something wrong. Do the following with the TIU powered on:

• Count the TIIU's blinks when it powers on. I'm going to assume that it still blinks 3 times.
• Using the remote, enter: Menu/System/TIU Setup/Add TIU, and add TIU #3 if it's not already present.
• Using the remote, enter: Menu/System/TIU Setup/Delete TIU, and delete any other TIUs, leaving only TIU #3. 
• Using the remote, enter: Menu/System/TIU Setup/Edit TIU and edit TIU #3 to be TIU#1.

 Trying adding TIU #3 to the dcs remote (if you haven't already)

Delete tiu #1. This will open up Tiu #1  (make it available)  so  you can  can edit Tiu #3 to Tiu #1. Should go now.

Gregg,

There seems to be an echo in here...

 Right ... right   !!  

SUCCESS !!

Thank you Barry,

Your directions did the trick.  The TIU was immediately recognized and now blinks only once as it usually did at startup.

Do you have any idea what might have caused the problem?  

Nothing unusual happened while the trains were running.

Thanks again,

Ron

P.S.   Your book is my bible and is my go-to for troubleshooting, but I just couldn’t get a handle on this issue. 

Ron,

Do you have any idea what might have caused the problem? 

Absolutely - you did something!
