Abstract

PURPOSE:To simplify the processing and to reduce the overhead of the central unit and the communicating line in a system composed of the central unit and terminal equipment, by decoding codes of output data and by assigning output data. CONSTITUTION:By decoding codes by defining a UI(0) 3 and a UI(1) 4 of an output message 1 as unit discriminations and a US7 and a US8 as unit separators when output data from a central unit 10 are received at a terminal controlling device 20, it is assigned by the terminal controlling device whether the output data from the central unit 10 are outputted to terminal equipment 40 or to shared output equipment 50. Therefore, in the central unit 10 it can be considered that the shared output equipment 50 is one of output device 41 existing in the terminal equipment 40, an thus output data plementation becomes easier. Moreover, those data can be united by mixing the data of the terminal equipment 40 and the shared output equipment 50 to an output message 1 from the central unit 10.
