This motherboard supports RS232/422/485 on COM1, 4, 3 ports. Please refer to below table for the pin definition. In addition, COM1, 4, 3 ports (RS232/422/485) can be adjusted in BIOS setup utility > Advanced Screen > Super IO Configuration. You may refer to our user manual for details.

Installation of ROM Socket

Do not apply force to the actuator cover after ic inserted.
Do not apply force to actuator cover when it is opening over 120 degree, Otherwise, the actuator cover may be broken.
The yellow dot (Pin1) on the ROM must be installed at pin1 position of the socket (white arrow area).
Make sure the white dot on the ROM is installed outwards of the socket.
For further details of how to install ROM, please refer to ASRI website. Warning: If the installation does not follow as the picture, then it may cause severe damage to chipset & MB.
