Patent ID: 8588328

Claim:
An information transmission system comprising: a first information transmission device, including, a first transmission section that transmits information to a first transmission path of a pair of transmission paths that transmit information serially, a first reception section that receives the information from a second transmission path of the pair of transmission paths, a first waveform shaping section that, according to first setting information, shapes at least one of a signal waveform of the information for transmission from the first transmission section, and/or a signal waveform of the information for reception by the first reception section, and a first controller that, when establishing communication, controls the first transmission section so as to transmit predetermined first information that requests communication establishment, and effects control so as to change the first setting information and controls the first transmission section to re-transmit the first setting information when the first reception section has not received the first information within an interval from the beginning of transmission of the first information until a predetermined duration required for communication establishment has elapsed; and a second information transmission device including, a second reception section that receives the information from the first transmission path, a second transmission section that transmits information to the second transmission path, a second waveform shaping section that, according to second setting information, shapes at least one of a signal waveform of the information for transmission from the second transmission section and/or a signal waveform of the information for reception by the second reception section, and a second controller that effects control so as to change the second setting information and controls the second transmission section so as to transmit the first information, when the first information is received by the second reception section.
