15) Infrared Connector (10-1 pin IrDA)
This connector supports an optional wireless transmitting and receiving infrared
module to the CIR and SIR connectors for both wireless transmitting and remote
control functions through an external infrared module. This connector supports
an optional wireless transmitting and receiving infrared module. This module
mounts to a small opening on system cases that support this feature. You must
also configure the setting through UART2 Use Infrared (see 4.4.2 I/O Device
Configuration) to select whether UART2 is directed for use with COM2 or
IrDA. Use the five pins as shown in Back View and connect a ribbon cable from
the module to the motherboard SIR connector according to the pin definitions.
(NOTE: The SIR module does not come with the motherboard package.)
