problem with 2nd tiu ID

 Does one of the TIUs have to be TIU #1?

It should be. Just power up one TIU and set it to TIU #1. You must have done something out of sync for them both to be at address#2.

If your remote or device doesn't show TIU #1 is available you'll have to delete it, and then it will be available. I fear that you may loose your engine associations and any consists may need rebuilding if they don't respond properly.

Maybe I didn't explain the problem clearly. My DCS remote shows that I have TIU 1 (the added TIU) and TIU 2 (the original). However, both TIUs blink twice when they are powered up. How do I reset TIU 1 so that it only blinks once? I have deleted it and then added it back, but it still blinks twice.

Only power up the one you wish to change!

Menu :

TIU set up:

select TIU (#2 the one you wish to change!) :

Edit TIU address (to the one you want now, TIU #1)

or Reset (factory) the TIU

Thanks for your reply. Unfortunately the factory reset didn't work. TIU 1 still blinks twice when I power it up.

Further thoughts?

Joe is right, power up ONLY the TIU you wish to fix.  Make sure the remote has the current TIU address enabled.  You should then be able to edit the TIU address or factory reset it.

I just tried that here, no problem at all.

Are you using a DCS remote or the DCS app to control things?

Did you factory reset TIU #2?

Do you have a four wire handset cord to connect the DCS remote directly to the TIU?

Are you saying that after a factory reset, a TIU still flashes twice? 

As noted above, power up just one TIU, and then using the remote, edit its address to TIU.  If the remote won't let you do this, it will be necessary to delete TIU#1 from the remote first.

It is not TIU #1 inside it's memory. It's a duplicate #2. Maybe that's confusing you here?

You probably had power to both TIUs when you tried changing the address at first. Only power up the one you wish to change. If you can't get the remote to talk to it, we'll go from there.

If you plug the remote in with a 4-pin curly cord, it will ONLY talk to that TIU, that's the way to insure you are dealing with the right TIU.

Maybe this helps you under stand.  The Remote has to have the TIU number added, and the TIU has to have the address you want.  You have the ability to change the TIU to any address you want (1 to 5). The remote can have TIU address 1 to 5.

So as told by others power only the TIU you want to work with.  If it is address 2, address it and then change it to 4 as an example.  Power it off, wait a few seconds and power up.  TIU should blink 4 times.  It you can not change it, then the TIU may be defective.  Possibly memory chip.  G

Didn't have a phone cord and so was unable to try out the suggestions made yesterday. The physical connection was helpful in isolating problems. 

I was able to change the address of the additional TIU back to 1 and it now blinks once. One helpful hint for anyone who encounters this problem in the future is to use the TIU version on the DCS menu to check on the "true" address of a TIU. My remote showed TIU 1, but when I checked the version of TIU 1, an error message came back to the effect of "TIU Failure." (Thus TIU 1 doesn't really exist.) When I checked TIU 2, the remote showed version 5. So I deleted TIU 1 and then edited the address of TIU 2 to TIU 1. (As Engineer Joe observed, there was no TIU 1 in memory.)

The other lesson as several of you pointed out is to make sure that only one TIU is powered up during this process. Otherwise you can end up with TIUs that have the same ID.

Thanks to all of you for your excellent suggestions and patience. This feels like a big hurdle overcome.

When you speak of "TIU version," you're speaking of something different, namely, the software loaded into that TIU.  Version 5 is quite outdated.  All remotes and all TIUs should have the same software version, which is now 6.1.

Glad you got it changed. I was worried that it was out to lunch! Sometimes they go out, in funny ways.

It would be good to update to the latest DCS versions if your stuff isn't.
