16) Serial Infrared Module Connector (5-pin IR)

This connector supports an optional wireless transmitting and receiving infrared

module. This module mounts to a small opening on system cases that support

this feature. You must also configure the setting through 4.4.5 Peripheral Setup

to select whether UART2 is directed 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 IR connector according to the pin definitions.

17) SMBus Connector (5-1 pin SMB)

This connector allows you to connect SMBus (System Management Bus) de-

vices. SMBus devices communicate by means of the SMBus with an SMBus

host and/or other SMBus devices. SMBus is a specific implementation of an I

bus, which is a multi-device bus; that is, multiple chips can be connected to the

same bus and each one can act as a master by initiating data transfer.
