Printed Circuit Board and Server Using the Same

A server, comprising:

• a plurality of printed circuit boards (PCBs), each comprising:
• a plurality of receiving components, each comprising:
• a receiving unit configured for receiving a radio signal;
• and
• a first control unit coupled to the receiving unit and configured with a first comparison table storing related information of the receiving component and related information of the corresponding PCB, the first control unit being configured for decoding the radio signal according to the first comparison table, so as to obtain a corresponding control signal;
• and
• a sending component, comprising:
• a sending unit configured for sending the radio signals;
• and
• a second control unit coupled to the sending unit and configured with a second comparison table storing the related information of the receiving components and the related information of the PCBs, wherein when the sending component outputs the control signals through the second control unit, the second control unit generates the control signals according to the related information of the receiving components and the related information of the PCBs, and encodes the control signals to generate the radio signals.
