Abstract

PURPOSE:To prevent a receiving error of a control code and also make it unnecessary to discriminate a character of a general data, by transmitting and receiving a general data and a control code by use of separate channels of the high speed circuit. CONSTITUTION:The high speed transmission and receiving control part 10 selectively operates the low speed adaptor 17 and the control code generation part 16 by use of the selective signal line 11. A data and a control code from the low speed circuit 15 are loaded on the high speed channel bus line 12 by the adaptor 17 and the control code generation part 16 under control of the control part 10, and are sent out to the high speed circuit 14 through the high speed adaptor 13. A multiple frame which is received by the high speed adaptor from the high speed circuit 14, at the time of receiving, is divided into 8 bits each, and the data of channels 1-n are transmitted and distributed to the low speed circuit 15 corresponding through the low speed adaptor 17. Also, the control code of 8 bits of channel (n) is decoded by the control code generation part, and the state of each channel is controlled.
