Installation Instruction
USB3 ;USB4;Serial Port Connector(COM2)
Besides USB1,2 on the back panel, P2E/333 series of mainboards also have two 8-pin head-
ers on board which may connect to front panel USB cable( optional ) to provide additional four
USB ports. The serial port COM2 is not available on the back panel. Therefore, we provide a 9-
pin header.
Infrared Header (IrDA)
This connector supports wireless transmitting and receiving device. Before using this func-
tion, configure the settings for IR Address, IR Mode and IR IRQ from the INTEGRATED
PERIPHERALS section of the CMOS SETUP.
