The 465T replacement transmitter is a direct replacement transmitter for all 1 and 2 button binary systems. The 465T can be coded to systems that originally used the 460T one button binary by following the instructions in step 3. On the circuit board, there are 10 traces which make up the code. On systems that used the 460T, there will be two additional traces which determine the button(s) of the 465T that will control the system.
