11) Serial IR (SIR) (5-1 pin) and Consumer IR (CIR) (5-pin) Connectors
This connector supports an optional wireless transmitting and receiving infra-
red module. This module mounts to a small opening on system cases that sup-
port this feature. You must also configure the setting through UART2 Use In-
frared (see 4.4.2 I/O Device Configuration) to select whether UART2 is di-
rected 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’s SIR connec-
tor according to the pin definitions. An optional consumer infrared (CIR) set
connects to the CIR and SIR connectors simultaneously for both wireless trans-
mitting and remote control functions through one external infrared module.
Wake On PS2 KB/CIR in 4.5.1 Power Up Control must be enabled in order to
use Consumer Infrared (CIR) power up.
