<p>A data transmission system for sending parallel data from the transmitting side to the receiving side. When a predetermined period of time t1 has passed after the transmission of an i-th data item DTi, the transmitting side sends a high level data transmission signal DS to the receiving side. Upon receipt of the high level data transmission signal DS, the receiving side reads the i-th data item DTi and sends a high level data reception signal DR back to the transmitting side. The transmitting side receives the high level data reception signal DR, and the i-th data transmission cycle is completed. To transmit the next (i+1)th data (DTi + 1), the transmitting side sends a low level data transmission signal DS when a predetermined period of time t1 has passed after the transmisssion of the (i+1)th data item. Upon receipt of the low level data transmission signal DS, the receiving side reads the (i+1)th data (DTi + 1) and sends the low level data reception signal DR back to the transmitting side. The low level data reception signal DR is received by the transmitting side, and the (i+1)th cycle of data transmission is completed. The data is thus transmitted successively by repeating the i-th and (i+1)th data transmission cycles.</p> |
