Abstract: A diagnostic server and a controlling method are provided. In the method, the diagnostic server receives a packet including at least one frame and performs error checking on each frame included in the packet. The diagnostic server receives a retransmitted packet upon determining from the result of error checking that a frame in the packet has an error. The diagnostic server performs error checking on each frame included in the retransmitted packet and restores the frame included in the packet based on the retransmitted packet when a frame, which is located in a location corresponding to the error frame, included in the retransmitted packet has no error. In the case where a packet including product information is transmitted, this method can reduce the number of retransmissions of the same packet required to acquire an error-free packet.
