The synchronous data transmission system terminal of a transceiver always transmits bit by bit transparently when receiving and transmitting data. A computer parallel interface includes three ports respectively for a data register, a state register and a control register. Taking the characteristics of the three registers into account, we use the data register of the parallel interface to transmit data, the state register to receive data and synchronize clock and the control register to control the transceiver's PTT in this paper. At the same time, using the idea of inserting special code groups to realize the group synchronization, we also actualize the design of the synchronous data transmission system terminal of a transceiver and realize the two-way data transmission between the data terminal and the transceiver, providing the implementation scheme and the program design.
