<p><P>PROBLEM TO BE SOLVED: To provide a communication apparatus consolidated device capable of saving the space by installing communication apparatuses in a consolidated manner in a limited space, and saving the wiring of a communication system constituted of a plurality of communication apparatuses without changing the basic constitution of the communication apparatuses. <P>SOLUTION: The ECU (communication apparatus) consolidating device 1 is capable of storing a plurality of ECUs 2, 2 having a microcomputer 20 including a CAN controller 22, and has a CAN transceiver 15 (a transmitter-receiver unit) for achieving the transmission-reception of the signal by a CAN bus 16 by a physical layer in a common circuit 10. The common circuit 10 has a connection circuit 14 which is connected to input/output terminals Tx, Rx of the CAN controllers 22, 22, receives the signal from the output terminals Tx, Tx, outputs the signals commonly to the CAN transceiver 15, receives the signal from the CAN transceiver 15, and outputs the signal to the input terminals Rx, Rx of the CAN controllers 22, 22. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
