  • Data bus
    Patent number: 6453374
    Abstract: A bus system including a bus user apparatus and a method for communicating via the bus system are disclosed. The bus user apparatus includes means for means for selectively coupling a transmitter to the transmission line according to a protocol of the bus system. The bus system provides bi-directional communication over a single transmission line. The transmitter of the transmitting device is coupled to the transmission line during transmission. Upon completion of transmission, the transmitting device sends a permission to transmit signal to the next transmitting device according to the protocol, and decouples its transmitter from the transmission line. The next transmitting device couples its transmitter to the transmission line and begins transmission of data. Multiple bus users, both transmitters and receivers, are accommodated by the bus system, and bi-directional communication is supported.
