<div dir="ltr"><div><div><div><div><div><div>Guys,<br><br></div>I'm trying to get COR sorted via the Parallell port.<br><br></div>I've figured out I need to ground pin 15 in order to turn RX on and off.<br><br></div>
The problem is, I have a +5V signal from my radio when there is a carrier present.<br><br></div>Can anybody point me toward an easy circuit to be able to convert the +5V to a negative in order to turn the RX on and off? If I set ppinvert, it turns the RX on when I ground the pin - so that seems to be the way to go.<br>
<br></div>I've tried googling, but all sorts of stuff comes up!<br><br></div>Thanks,<br><br>James<br></div>
