When you input sound for S/PDIF IN, the LINE_OUT will output the sound. Mute LINE_OUT to impede sound output from S/PDIF IN.

15. Infrared Module connector (10-1 or 10-2 pin IR_CON1) (optional)

These connectors support an optional wireless transmitting and receiving infrared module. The module mounts to a small opening on the system chassis that support this feature. You must also configure the UART2 Use As parameter in BIOS to set UART2 for use with IR.

Use the ten pins as shown in Back View and connect a ribbon cable from the module to the motherboard SIR connector according to the pin definitions.
