Title:
DUAL BOARDS AND METHOD FOR CONFIGURING MASTER/SLAVE OF DUAL BOARDS
Document Type and Number:
WIPO Patent Application WO/2020/091255
Kind Code:
A1
Abstract:
The present invention relates to a method for configuring a master/slave board during initial booting of dual boards, and to the boards. The dual boards, according to one embodiment of the present invention, each comprise: a power source input unit to which AC voltage due to initial booting is applied; a voltage conversion unit for converting the applied AC voltage to DC voltage; a communication unit for transmitting, to the other board, a DC voltage value corresponding to the converted DC voltage, and receiving, from the other board, a DC voltage value of the other board; and a control unit which resets the voltage conversion unit, if an initial booting signal and the AC voltage are applied from the outside, and which converts the DC voltage converted in the voltage conversion unit to the DC voltage value, and which configures as a master board or a slave board by comparing the DC voltage value of each board transmitted and received via the communication unit.
