PURPOSE:To make the data conversion to a different code and the switching of a plurality of input and output switching with a program on a central processing device, by providing a switch code in a received electric message, in an interface device between a central processing device and a terminal device. CONSTITUTION:In a received electric messages (1)-(4), the types of an output device outputting the succeeding data 2 and the data conversion before the output is designated by an output designation switch code 1, and an input designation switch code 3 designates the input device inputting the data to be transmitted to a central processing device and the types of the data conversion to the inputted data. When the device is in reception state, a transmission control section 5 transmits the received electric message to a switch code detection section 6 and the result of the detection is registrated on an electric message control table 7. An electric message control section 8 makes the data conversion of the received data according to a table 7 and outputs the data via an output interface section 10 corresponding to the registrated output device. In the transmission state, the data is inputted from a designated input device with the table 7 and the electric message control section 8 and transmitted after the data conversion. |
