の接続検出装置。[Claims for Utility Model Registration] Multi-channel transceiver connection that creates a control signal for switching communication lines of the multi-channel transceiver based on detecting whether an external transceiver is connected to the multi-channel transceiver. The detection device is characterized in that the control signal is output by converting a change in the output current of the multi-channel transceiver into a voltage change as power is supplied from the multi-channel transceiver to the external transceiver. Multi-channel transceiver connection detection device.
