Abstract
A time division multiplex system for motor vehicles and other applications in which data signals are adapted to be sent through the system in cyclical fashion during each of a series of time periods. The system includes a communication line, a master unit connected to the communication line which includes a pulse-generating circuit for sending a plurality of timing signals out over the line for defining a plurality of time slots during each time period, and a plurality of transceiver units connected to the communication line. Each of the transceiver units is operable in either a transmit mode or a receive mode and includes an address-decoding circuit for identifying a selected one of the plurality of time slots on the line during each time period, a data-signal-transmitting circuit operable when the transceiver is in a transmit mode for sending the data signal out onto the line during the selected time slot, and a data-signal-receiving circuit operable when the transceiver is in a receive mode for receiving a data signal from the line during the selected time slot. With the system of the present invention, data can be transferred onto the line from any one transceiver and received from the line by any other transciever or transceivers to provide a system having a great deal of flexibility. The system also includes circuitry to permit power for the transceivers to be sent over the single communication line from the master unit.
