信装置。In a contention type communication system in which a plurality of transmitting/receiving stations share communication channel resources, in the transmitting/receiving station, the communication path from the transmitting section of the own station to the receiving section of the own station is configured equivalently as a resistive bridge circuit, and A communication path shared by the plurality of transmitting and receiving stations is configured such that both ends thereof are terminated with a resistance equal to the characteristic impedance of the transmission cable constituting the communication path, and the communication path is connected to each of the plurality of transmitting and receiving stations. By configuring the communication path to be on one side of the bridge circuit, the communication path is configured to be a bridge side having an impedance half of the characteristic impedance, and further, the communication path is configured to be on the other side of each of the bridge circuits, and By adjusting the resistance value on the other side of each bridge circuit, the transmitting signal of the own station received by the receiving section of the broadcast receiving station is weakened, and by receiving the transmitting signal of the other station while the own station is transmitting, A data communication device characterized in that a communication collision within a communication channel resource is detected.
