Electronic control device for remote control and teleoperation system using same
An ECU for a main remote control has a termination resistance having a first terminal connected to a high level signal line CAN of a CAN cable and a second terminal connected to an external terminal of a connector. The CAN cable also has a low level signal line CAN connected to an external terminal of a connector. A power wire VCC is divided at its midportion, and respectively connected to external terminals of the connector. When a connector is connected, the termination resistance is connected between the high level signal line CAN and the low level signal line CAN of the CAN cable by a jumper line, and power is supplied through a jumper line. When the connector is disconnected, the termination resistance is not connected and the ECU for a main remote control does not operate since no power is supplied thereto.
