Abstract

PURPOSE:To reduce a hardware quantity and simplify a program logic to reduce the unit cost, by providing a means, which adds information for transmission error detection to information from the terminal which does not add information for transmission error detection, in the part corresponding to the receiving circuit of this terminal. CONSTITUTION:Though cyclic redundancy check CRC information is added to information transmitted from terminal 2, CRC information is not added to information transmitted from terminal 3. Then, CRC information is added to the end of information, which is transmitted from terminal 3, in CRC operation information adding circuit 7 before information is inputted to data transmitting and receiving circuit 4, and thus, this information has the same format as information from terminal 2. Consequently, the same logic can be adopted in respect to data transmitting and receiving circuit 4, CRC operating circuit 5, CRC check circuit 6 and programs.
