You should ask each question clearly. Re-read your post to make sure it's clear what you're asking about. With that in mind, here goes.
You state you downloaded the software for the TIU. You should save it to your desktop when prompted so you can easily find it.
You talk about the LUCI. You just use your remote to check your software inside each TIU. So maybe you are asking about how to check the WIFI software?
I looked over your past posts here on the forum. I couldn't help but notice that you did not directly answer people trying to help you in the past. In each post you did state an issue you had. You just didn't seem to help us after that.
We're not here to make fun of you. To help, we need answers so we can formulate a reply that will help.
You stated that your system works with the DCS remote so that answers a lot of questions already. Just try to provide enough info and answer questions to move forward in the future.
We are not there, so we need you to do extra so we can understand what you're seeing without us being there for ourselves.
