Hi Chris,
Thanks for your reply. I no longer have multiple TIUs in my remotes, only TIU 1, I've deleted the extras & all TIU's are number 1. I enter my engines and record their addresses in a written log so there are no conflicts. At this time it is working for me & I have no need to utilize more than one TIU at a time.
I could try some of your suggestions but this approach is working for me. I may not have found a glitch in the system but there isn't a need for me to get something to work that I will never do. I don't know how many operators use more than 1 TIU at a time but the more complicated we make it the more problems seem to arise.
This all started with me trying to upgrade to VER 6.1 which I have on all my remotes & TIU's now & its working. I just want to run my trains with my Grandsons & friends.
There are a lot of ways to skin a cat & for me, I found a solution. Thanks again for your input.
Joe
