Abstract
A master-slave system includes a master and a slave. The master includes a first communication interface, a master controller, and a voltage meter. The voltage meter is connected to the first communication interface and the master controller. The slave includes a second communication interface, an input unit, a slave controller, and a control indicator unit. The control indicator unit is connected to the second communication interface and the slave controller. The salve controller controls voltage of a node between the control indicator unit and the second communication interface to change between a high logic level and a low logic level according to signals from the input unit. The voltage meter is connected to the control indicator unit to detect the voltage of the node. The master controller controls the master to execute a function according to change of the obtained voltage within a preset period.
