There is a 16 pin interface between its faceplate and the control box. I want to replace the faceplate by my computer.
Right now, I have decoded the control command that send from the faceplate, they are analog signals, and the pin is KEY0 and KEY1. However, I cant decode the response signals from the control box. It seems that they are using I2C. So, have any ideas? Or anyone know its protocol?
