r (J13, Rear IrDA)
These connectors support the 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 UART 2. Use Infrared in Chipset Features Setup to
select whether UART 2 is directed for use with COM2 or IrDA.
When IrDA is selected in BIOS, COM2 will be disabled. Use the
five pins or six pins as shown and connect a ribbon cable from
the module to the motherboard to the pin definitions.
