19) Infrared module connector (5-1 pin IR)

This connector supports an optional wireless transmitting and receiving infrared module. This module mounts to a small opening on system chassis that support this feature. You must also configure the UART2 Use As parameter in BIOS to set UART2 for use with IR. See section “4.4.2 I/O Device Configuration” for details.

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.
