Abstract

PURPOSE:To obtain an efficient circuit configuration, by connecting a switchboard and a computer system by 1 group of circuits, in case when a terminal equipment whose code system is different is connected to the computer system through the switchboard. CONSTITUTION:A register 26 has a storage address corresponding to a circuit number of a circuit connected to this system, and stores a kind of a code system used for communication of the circuit corresponding to this address. In this state, when a transmission request of a transmitting data of a data memory 22 is outputted, a communication program 24 reads a kind of a designated circuit code system from the register 26, converts the transmitting data on the memory 22 to a code of a code system of the designated circuit from an internal code by use of a conversion table of a table 25, and stores a converted data in a buffer 27. Subsequently, the transmitting data of the buffer 27 is sent out to the circuit in order through a communication controller 28. Also, when receiving, it can be processed in the same way by use of the register 26.
