Hi. Thanks for now.
I did that but the 12v did not appear
But I was seeing that when doing that bridge, RE1 is activated if I am not mistaken.
Then I jumped RE1 and the 12v + and the 12 v - appeared
It is seen that the problem is in the standby source despite the fact that 3.3v and 2.5v reach the connector.
Well then I value your answer because I think it is correct.
