Title: Data transmission system
Inventor: ASAHI SHIGEO
IPC: H04Q9/00
Filed: 1994-01-13
Abstract: PURPOSE:To secure the high speed response of a device to be controlled by issuing a multi-address command from a master station and making a slave station recognize the data addressing to its own station by the leading address and the relative address when data is transmitted from the master station to each slave station by performing a selecting. CONSTITUTION:At the time of a selecting, a multi-address command is issued from a master station to each slave station 2 to 4 via a signal transmission line 5. This multi-address command notifies to all the slave stations 2 to 4 that a mode enters a special transmission mode from the next time. Next, effective information data is transmitted. This show relative address information. By combining the data with the leading address to be transmitted next, the data addressing to each slave station 2 to 4 can be discriminated. Next, by continuing the data addressing to each slave station 2 to 4 by some bytes or so, the data is transmitted as block data. Thus, instead of successively transmitting address data and control data to each slave station 2 to 4, integrated control data is transmitted together. Thus, the number of times of address transmission can be reduced.
