In all the rigamarole I went through to program an engine a ran across a thought about making sure the TIU is set to one. Barry has confirmed for programming this is not necessary, only if recovering an engine.
In an attempt to reset an extra TIU to Address one I found it absolutely refuses to be changed. At first, not responding to a remote, I thought it was a transciever board issue. Upon reseating the board I got the unit talking with the remote, but it still won't change the address.
I have tried using power on fixed one, aux., tethered and untethered. What could possible be the problem. Thanks.
