I'm having trouble getting my friend's DCS remote to communicate with the TIU. I spent the afternoon upgrading the TIU and remote to version 4.20 software. I had no issues when I downloaded the software.
I tested the TIU and remote on a layout that I knew had no issues with DCS. So I swapped out the existing TIU and remote with my friend's equipment. I could not get my friend's remote to communicate with his TIU. I even performed a reset on both the TIU and remote, but still no change. I then tried supplying a tether between the remote and TIU. To my surprise, the system worked perfectly. I know this isn't a signal interference issue, because the remote on the other DCS system had no trouble communicating wirelessly with the TIU.
Is it possible that a board in my friend's TIU or remote has gone bad?
