<p dir="ltr">Hi,</p>
<p dir="ltr">I want to connect a serial console to my device but need a bit of advice before purchasing components.</p>
<p dir="ltr">According to the article linked below, I need a ' 3.3V TTL to RS-232 level shifter'</p>
<p dir="ltr"><a href="http://www.cyrius.com/debian/kirkwood/qnap/ts-219/serial/">http://www.cyrius.com/debian/kirkwood/qnap/ts-219/serial/</a></p>
<p dir="ltr">Do these converters work bidirectional? Or does it specifically need to be 3.3V TTL to RS-232 and not RS232 to 3.3v TTL?</p>
<p dir="ltr">Anything to avoid?</p>
<p dir="ltr">Probably wishful thinking, but.. I guess TTL to USB wouldn't work without intervening electronics?</p>
<p dir="ltr">Cheers<br>
James <br>
