Claims

[Claims for Utility Model Registration] A data line termination device or a data terminal device configured such that a data transmitter and a receiver correspond to each other and can transmit and receive data to each other, and a connection between the two devices or a data communication line. an output standard discriminating device that determines whether the output standard of the connector is that of a data line terminating device, or whether the output standard of the connector is that of a data terminal device that is different from the data line terminating device; A connector fitting member that fits into a predetermined terminal of the connector in an electrically connected state; and a signal detection device that detects the state of a signal flowing to the predetermined terminal of the connector via the connector fitting member. and a standard for determining whether the connector conforms to the output standard of a data line termination device or the output standard of a data terminal device, based on the state of the signal flowing to a predetermined terminal detected by the signal detection means. An output standard discriminating device comprising: discriminating means;
