Abstract

PURPOSE:To convert the transmission speed without changing a control procedure, by converting low-speed transmission data to high-speed data to output, and discriminating received data, which is converted to high-speed data, into low-speed data and high-speed data in a high-speed data detecting circuit. CONSTITUTION:When low-speed transmission data is inputted from an input terminal 3, this data is stored temporarily in a buffer memory 15 and is read out in a high speed and is outputted to a high-speed converted transmission data terminal 11 through a switching circuit 16. High-speed transmission data is inputted to an input terminal 8 and is outputted to the terminal 11 as it is. Meanwhile, when received data which is converted to a high-speed data is inputted from a terminal 12, it is detected in a high-speed data detecting circuit 17 whether this data is high-speed received data or not, and a gate 18 is opened to output it to a high-speed received data terminal 9 if it is high-speed received data. If it is not high-speed received data, the gate 18 is closed, and a gate 18' is opened, and data stored in a buffer memory 15' is read out in a low speed and is outputted to a low-speed received data terminal 4.
