PURPOSE:To transmit inexpensively a large capacity of data without reducing the transmission speed of a signal requiring high speed transmission by adding a simple program to a data transmission system using SDA (serial data adaptor). CONSTITUTION:The SDA is provided with a means selecting prescribed pair data consisting of plural data and inputting the selected data to the 1st RAM of the SDA together with a block signal indicating the kind of the data and a means discriminating the kind of pair data by the block signal written in the 2nd RAM of the SDA and reading out prescribed pair data; and a signal requiring high speed transmission is always inputted to the 1st RAM. A signal which may be transmitted at a low speed is transmitted as a pair data. |
