Infrared (IrDA) Port

The Infrared Data Association (IrDA) port provides a two-way wireless communications port using infrared as a transmission medium at the basic level. There are two basic infrared implementations provided; the Hewlett-Packard Serial Infrared (HPSIR) and the Amplitude Shift Keyed Infrared (ASKIR) methods. HPSIR is a serial implementation of infrared developed by Hewlett-Packard. The IrDA (HPSIR and ASKIR) signals share Serial Port 2 with the modem and RS232 functions on the port. This port can be enabled/disabled and configured for HPSIR or ASKIR signals in the BIOS Setup Utility. Refer to Chapter 4, BIOS Setup Utility for more information.

The HPSIR method allows serial communication at baud rates up to 115k baud. Each word is sent serially beginning with a zero value start bit. A zero is sent when a single infrared pulse is sent at the beginning of the serial bit time. A one is sent when no infrared pulse is sent during the bit time.

The Amplitude Shift Keyed infrared (ASKIR) allows serial communication at baud rates up to 19.2k baud. Each word is sent serially beginning with a zero value start bit. A zero is sent when a 500 kHz waveform is sent for the duration of the serial bit time. A one is sent when no transmission is sent during the serial bit time.

Both of these methods require an understanding of the timing diagrams provided in the Super I/O controller chip (W83627HG) specifications available from the manufacture’s web site and referenced earlier in this manual. For more information, refer to the Winbond Electronics, Corp. chip specifications and the Infrared Data Association web site at http://www.irda.org.
