A detonator includes a control circuit and a charging circuit. The control circuit receives a first signal transmitted using a voltage applied to a cable by a blasting device and transmits a second signal to the blasting device using a current flowing to the cable. The charging circuit performs a charging operation by receiving the voltage through the cable. The charging circuit stops the charging operation while the control circuit transmits the second signal to the blasting device.
