SIR/CIR Connector (J13)
If you have an Infrared device, this mainboard can implement SIR (Standard
IR) and CIR (Cirsumer IR) transfer function. To enable the IR transfer func-
tion, follow these steps:
SIR Pin Assignments:
1=VCC 2=VCC 3=IRRX
4=Ground 5=IRTX
CIR Pin Assignments:
1=VCC 2=CIRRX 3=NC
4=Ground 5=NC
Step 1.
Attach the 5-pin infrared device cable to J13 connector. (Refer to
the above diagram for IR pin assignment.)
Step2.
Configure the Infrared transfer mode in the UR2 Mode field of
Integrated Peripherals menu in BIOS Setup. This mainboard sup
ports IrDA, ASKIR, Normal and SCR transfer modes.
