[0051] In combination Figures 2-10 , the power supply process and the debugging process of the connecting device to the bus device 6 are described in detail:

[0052] Power supply process:

When the output switch SW2 of the power supply output circuit 302 is opened, the initial output voltage Vout is transmitted to the power supply modulation circuit 501 for modulation to obtain the working power Output_OUT for the bus device 6 to work.

[0055] Debugging process:

[0056] The host computer 8 is connected to the bus device 6 through the J6 interface (physical interface) in the USB interface circuit 201, and the host computer 8 sends instructions or configuration parameters in sequence through the USB signal circuit 203, the signal processing module 4 and the signal modulation circuit 502, so as to convert them into communication signals (KNX signals) readable by the bus device 6 through the signal processing module 4 and the signal modulation circuit 502.
