ELECTRONIC DEVICE, WORK MACHINE, AND MANAGEMENT SYSTEM FOR TERMINATION RESISTANCES

To easily perform setting (connection and non-connection) of a termination resistor. An electronic device (2) configured to be connected to an in-vehicle network of a working machine (1) and to work for the working machine (1), includes: a termination resistor (4) configured to be connected to the in-vehicle network; a switch part (5) configured to be switched between a connection state where the termination resistor (4) is connected to the in-vehicle network and a non-connection state where the termination resistor (4) is not connected to the in-vehicle network; and a control part (6) configured to control an switching operation of the switch part (5).
