As one embodiment of the invention, status indicator lamp 30 is additionally provided with circuit board, for being currently connected with interface
The processor of the connection of device 10 is identified.
What Fig. 4 showed the communication interface changing method of processor provided in an embodiment of the present invention realizes flow process, the process
The communication interface changing method of device is applied to the circuit structure of the circuit board shown in Fig. 3.As shown in figure 4, the communication of processor connects
Mouth changing method is comprised the following steps：
Step S101：When electricity on the circuit board, switching switch conduction corresponding with default default processor is controlled,
Control except other switching switch OFFs switched in addition to switching corresponding with the default default processor, will be described default
The communication interface of default processor be attached with the interface connector.
In embodiments of the present invention, when circuit board does not go up electricity, switch S is in off state, i.e., now do not process
Device is connected with interface connector 10.When electricity on circuit board, control switching switch S corresponding with default default processor and lead
It is logical, other switching switch OFFs in addition to switching switch corresponding with default default processor are controlled, will be default
The communication interface of default processor is connected with interface connector 10.
Wherein, default default processor can be any one processor in multiple processors (X1～Xn), preset
Default processor can be pre-set by user, for example, user can arrange processor 1 for default default processor, also may be used
