If the I/O port level signal collected is high level, 485 communications then between 485 communication ports of described debugging air conditioner device and air-conditioner set are connected, namely user has accessed 485 communication modes according to its actual demand, and therefore, the target communication mode that identifiable design goes out user is 485 communications; Otherwise if the I/O port level signal collected is low level, then user does not access or disconnects 485 communications, this kind of situation then thinks that the target communication mode of user is UART communication.
In other embodiments of the present invention, also compatiblely can adopt above two schemes, and can be as the criterion with the target communication mode of up-to-date acquisition (can obtain by receiving set-up mode, also can obtain by IO detection mode), the communication modes of debugging air conditioner device is controlled.It should be noted that, during compatible employing two schemes, the situation simultaneously being obtained target communication mode by two kinds of approach may be there is, for this situation, by carrying out priority setting in advance, such as give " being arranged by display board " mode higher priority etc., solve the problem that target communication mode that two kinds of modes obtain is inconsistent.

In such cases, UART communication is owing to can not normally can carry out by the interference of 485 chips, and therefore, now, the effective communication mode that debugging air conditioner device adopts is 485 communications.
S303: when described target communication mode is the second communication modes, controls as off working state by the Enable Pin of described communication chip by described communication chip; Wherein, the second communicating circuit of forming of described second communication interface and described pull-up resistor circuit is for providing the communication function of described second communication modes.
If described target communication mode is UART communication, for ensureing that UART communication signal is not disturbed by 485 chips, and then ensure normally carrying out of UART communication, need the technical requirement according to 485 chips, the level state of described 485 chip enable ends is controlled the inverse state for above-mentioned state: low level or high level, guarantee that 485 chips are in off working state, thus, now, the effective communication mode that debugging air conditioner device adopts is UART communication.
