Can four wireTX connected with TU810?
I have TU810 and AI810 but during installation it found that our system is four wire so i want know that either four wire system is connected with this TU810 model or i need and other type of TU.Document shows that for four wire termination you should use TU830 with AI810.
so i need to find out is it possible to connet four wire signal (external power)with TU 810 if yes provide wiring connection.
