Hello. I got an ESI controller that has a HD-LM Thyssen Krupp door controller. It has a 6300 PA 4 board and a UIT mounted on top with a 6300 HL 1 board. Says show faults no faults. The door board needs to be replaced. Does anyone know how to program the new board ? Can it be done from the on board UIT. I see a telco connection port on the uit.
