18) Standard IR (SIR) (5-pin) and Consumer IR (CIR) (5-1 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 connector
according to the pin definitions. An optional consumer infrared (CIR) set con-
nects to the CIR and SIR connectors simultaneously for both wireless transmit-
ting and remote control functions through one external infrared module. Wake
On PS2 KB/Mouse in 4.5.1 Power Up Control must be Enabled in order to use
Consumer Infrared (CIR) power up.
