ABSTRACT:
A receipt acknowledgement method which is applied to a multiplex transmission system provided with a plurality of multiple nodes (11 to 17) connected to one another through a multiplex bus (18), and is capable of conducting efficient data transmission, and in which a transmitting multiplex node (13) sends out a frame and, after entry into an ACK signal area of the frame, sends out a delimiter sign consisting of passive and active two bits with a four-bit interval, thereby dividing the acknowledgement signal area. The receiving multiplex nodes (11, 12, 14 to 17) are synchronized according to an active bit sent out from the transmitting multiplex node (13), and returns ACK signals to the ACK signal area in the predetermined order when data transfer on the transmission request frame has been normally performed, whereby data transmission can be conducted at high speed with improved efficiency.
