RxD, TxD Active

Common Options : Hi, Hi or Lo, Lo or Hi, Lo or Lo, Hi

Quick Review

This BIOS feature allows you to set the infra-red reception (RxD) and transmission (TxD) polarity.

It is usually found under the Onboard Serial Port 2 BIOS feature and is linked to the second serial port. So, if you disable that port, this feature will disappear from the screen or appear grayed out.

There are four options available, based on combinations of Hi and Lo. You'll need to consult your IR peripheral's documentation to determine the correct polarity. Choosing the wrong polarity will prevent a proper IR connection from being established with the IR peripheral.
