記載のデータ伝送装置。[Claims for Utility Model Registration] (1) A data transmission device that transmits predetermined data by synchronizing a pair of transmitters/receivers connected via a data signal transmission line with a transmitting/receiving timing signal. In the transmitter, the transmitter includes a specific data discrimination circuit that discriminates whether the transmission data matches preset specific data, and a specific data discrimination circuit that determines whether the transmission data matches the specific data set in advance, and a specific data discrimination circuit that determines whether the transmission data matches the specific data set in advance, and a a transmitting circuit that transmits predetermined transmission data; the receiver includes a receiving circuit that receives data transmitted from the transmitting circuit based on the receiving timing signal; and a receiving circuit that receives the receiving timing signal in the circuit. 1. A data transmission device comprising: a data discriminating circuit that deems that the specific data has been received based on the timing when predetermined data is not received based on the timing. (2) The data transmission device according to claim (1), wherein the specific data can be freely set based on transmission frequency or the like.
