Use two WLED

hello, i use google translate
I have a problem, I just installed a second board.
When I turn on the first board, the second also turns on.
the first at the address Ip: 192.168.200.10 and the second 192.168.200.15.
What parameters do I need to modify ?
thanks
Mickael

Turn off the Sync setting in the first board.
