The FIR Module
The Notebook is equipped with two FIR modules located on the rear and front
panels. Please see Figure 3-6 if you are having trouble finding these modules.
The FIR (Serial Infrared) module consists of one Light Emitting Diode (LED)
and one photo sensor. The operation of the FIR module is similar to the
operation of a television remote control device. The LED functions as a
transmitter and the photo sensor acts as a receiver. The transmitter emits a
signal stream consisting of data as pulses of infrared light. The receiver picks
up pulses of infrared light transmitted by other FIR modules.

= Make sure the “Infrared Port” field under the System Devices menu in the
BIOS Setup program is set to an available address. The “UART 2 MODE”
field should be set to Fast IR and the “Fast IR DMA Channel” should be
configured for DMA 0. Refer to Chapter 2 for information on the BIOS
Setup program.

= Ensure that the Notebook’s FIR module is properly lined up with the other
device’s FIR module. The FIR baud rate can reach 115,200 at a distance of
1 meter and a bias angle of 15
