Hello TI community,
On this occasion i'm here with the following enquiry: as you can see on the image attached i have a MAX3223 connection which i can't modificate and i need to looking the way to Disable the Power Down mode, that is to say, that i need the TX pin of the DB9 male connector always being enable with a negative voltage.
I dont know what to do, i tried to connect to the CTS pin an external 3.5V voltage but it doesnt work; also i put it a 0V too but neither worked.
Ill wait for your amazing help!!!
